Dental Erosion: What Acid Actually Does

Reviewed 31 August 2026. Numbers are quoted from a systematic review and meta-analysis of 24 studies in 21,541 adolescents, a systematic review of 10 studies in 5,805 participants, a laboratory study measuring the pH and acidity of named commercial drinks on human premolars, a retrospective study of 5,449 adults, a case-control study in gastroesophageal reflux, a randomised clinical trial of restorative materials, and fifteen years of one university tooth-wear programme. Each is listed at the end with its PMID. Written for people who have been told their enamel is “gone” and for the clinicians who have to say what to do next. Not medical advice.

The short answers

• Erosion is chemical dissolution of enamel by acid that is not made by bacteria; caries is the same dissolution where the acid is made by bacteria in plaque. The chemistry is shared and so are the modifiers: below a critical pH hydroxyapatite dissolves, and calcium-binding ligands (acid anions, proteins) and the salivary pellicle change how fast (Enax et al., Dent J (Basel) 2026-06-01, PMID 42345977). That single sentence explains why “sugar-free” does not protect a tooth from erosion.
• How common it is in young people has a pooled number now: a 2026 systematic review and meta-analysis of 24 studies covering 21,541 adolescents found an overall erosion prevalence of 37.6% (95% CI 26.3 to 49.7%), and carbonated drink consumption was significantly associated with erosion (OR 1.98, 95% CI 1.42 to 2.77; 7,785 participants), with I² = 80% (Juárez López et al., Oral Health Prev Dent 2026-05-01, PMID 42113589). Roughly one adolescent in three, and the association comes with serious heterogeneity.
• On energy drinks specifically, the honest verdict is “associated, but the evidence is thin”. A systematic review of three databases with no year limits screened 1,196 studies and could use 10 (5,805 participants aged 6 to 89): six looked at erosion, two at caries, two at saliva; 70% (7 of 10) were at high or serious risk of bias. Increased frequency or higher amount of energy drinks was associated with greater erosion risk, while the sports-drink relationship was inconsistent, and evidence for caries was “controversial” (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950).
• The pH facts, measured rather than asserted. In a study that put 75 samples of human premolar enamel into five minutes of Coca-Cola, Red Bull, their sugar-free versions or bottled orange juice, Coca-Cola had the lowest pH (2.36 ± 0.05) and the orange juice the highest (3.68 ± 0.03), while Red Bull had the highest titratable acidity (10.93 ± 1.17 mL NaOH) and buffering capacity (2.97 ± 0.36). Every beverage significantly increased surface roughness (Ra, Rq, Rz) (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138). Two lessons: “diet” versions are not safer on pH, and titratable acidity — how much base it takes to neutralise — matters as much as the pH number people quote.
• Sugar-free does not mean acid-free is testable and fixable: adding calcium formulations to an energy drink raised its pH in proportion to the dose and significantly reduced enamel roughness after exposure in a 60-specimen in vitro study, with a calcium/phosphorus/potassium complex performing best (Jácome et al., PLoS One 2025-01-01, PMID 41329760). This is laboratory evidence about a drink, not a clinical trial about teeth, and it should be read that way.
• Drinks are not the main cause in adults. A retrospective study of 2,482 adults diagnosed with erosive tooth wear against 2,967 controls (records 2019–2023) found significant associations with age 35–54 (OR 1.24, p = 0.03), male sex (OR 1.43), parafunctional habits — clenching, grinding, bruxism — and eating disorders (bulimia and/or anorexia nervosa) (Messias et al., Clin Oral Investig 2026-06-01, PMID 42287456). Two of those four are things a dentist can act on, and one of them is a reason to ask about the stomach, not just the glass.
• The stomach does show up in the mouth. In a case-control study of 100 adults with endoscopy-confirmed gastroesophageal reflux and 100 matched controls, the reflux group reported more acidic beverages, used more acid-suppressing medication and had more dry-mouth symptoms, and had significantly more caries and more erosive tooth wear (BEWE index) with lower salivary pH and flow; the effect was strongest in advanced disease and in Barrett’s oesophagus (Ali et al., BMC Oral Health 2026-07-01, PMID 42436443).
• What “wear” means in rate: fifteen years of the Radboud Tooth Wear Project (184 patients with a Tooth Wear Index ≥ 2, followed up to 9 years) describes tooth wear as a predominantly physiological, age-related process, with measured wear rates of 10 to 500 µm per year and a median patient-level progression of 20 to 100 µm per year and large variation between patients, teeth and surfaces (Loomans et al., J Dent 2026-07-01, PMID 41946429). That spread is why “your enamel is gone” is a bad sentence and “here is your rate of change” is a useful one.
• If you are being sold a big reconstruction, the trial evidence favours the smaller option. In a randomised clinical trial in adults with severe wear, after four years the 85 indirect (polymer-infiltrated ceramic network) restorations had inferior survival to the 88 direct composites — mean annual failure rate 8.7% versus 2.3% (p = 0.008) (Kanaan et al., J Dent 2026-02-01, PMID 41314372). The same group’s two-year randomised trial of opposing enamel wear found 0.41 ± 0.27 mm of wear under indirect milled resin-matrix ceramic overlays versus 0.20 ± 0.05 mm under direct bulk-fill composite (22 restorations in 22 patients) (Elhaddad et al., BDJ Open 2026-02-01, PMID 41723141). And the fifteen-year programme reported direct composite annual failure rates of ≤2.2% anteriorly and ≤2.9% posteriorly at 5.5 years, with molar indirect restorations failing significantly more often (hazard ratio 3.37; 8.5–15.5% versus 3.2–5.4% per year) (Loomans et al., J Dent 2026-07-01, PMID 41946429).

Two acids, one dissolution

The distinction that matters clinically is not “acid vs sugar” but where the proton comes from. In caries, bacteria in dental plaque ferment fermentable carbohydrate and the acid is produced in a sealed space against the tooth, so the exposure lasts as long as the plaque stays and the sugar keeps arriving. In erosion, the acid arrives from outside — a drink, a reflux episode, a swimming pool, a medication — and the exposure lasts exactly as long as the liquid is in contact with the surface, then saliva neutralises it. A recent chemistry review puts the shared mechanism precisely: low pH is decisive, but calcium-binding ligands such as acid anions and proteins accelerate dissolution by removing calcium from the equilibrium, and the protein pellicle and the biofilm both change the diffusion environment — which is why individual variation in saliva and microbiome makes the same habit produce very different teeth in different people (Enax et al., Dent J (Basel) 2026-06-01, PMID 42345977).

Practical consequences that follow from the mechanism, not from slogans. First, citric acid is worse than its pH alone suggests, because citrate binds calcium — which is why the measured titratable acidity of a drink tracks damage better than the pH number quoted on a blog (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138). Second, a sugar-free energy drink has the same acid load as the sugary one; the sugar is a separate problem that adds caries, not the reason the enamel dissolves (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138) (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950). Third, the buffering capacity of the drink matters — how much base it takes to bring it back to neutral — because that is how much saliva has to work with, and Red Bull’s measured buffering capacity in that study was as high as orange juice’s (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138).

How much, how often, and what “at risk” actually means

Frequency is the exposure variable in every design that measures it. In the systematic review of energy and sports drinks, it was “increased frequency or higher amounts” of energy drink consumption that was associated with greater erosion risk, not a single event (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950). In the adolescent meta-analysis, the pooled OR of 1.98 for carbonated drinks came with I² = 80% — meaning four-fifths of the variation between studies is real differences between populations rather than noise, which is another way of saying “the risk depends heavily on which population you are in” (Juárez López et al., Oral Health Prev Dent 2026-05-01, PMID 42113589).

For children, one more difference matters: the tooth itself is different. A 2026 paediatric review notes that primary teeth may be more susceptible to erosive tooth wear because their enamel is thinner, less mineralised and lower in microhardness, and their dentine has higher carbonate content and higher tubule density, with longer acid exposures producing higher demineralisation rates than in permanent teeth; the acquired pellicle in children also differs in composition and protective efficacy (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695). That is the mechanism-level argument for taking a five-year-old’s bottle of squash seriously, and for the review’s own prevention framing: risk assessment, dietary change and chemical protection with fluoride-based agents that form acid-resistant surface layers reducing enamel and dentine solubility (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695).

Now the population-level contrast that people misreport most. In 104 elite athletes, two-thirds reported consuming sports or energy drinks, gels or bars at least weekly, and despite good oral hygiene practices they had high prevalence of dental caries (63.5%), gingivitis (46.1%), irreversible periodontitis (26.9%) and erosive tooth wear (21.2%); 80% reported at least one oral problem with negative impact on daily activities (64.4%) and on training and performance (36.5%) (Khan et al., Nutrients 2022-11-01, PMID 36501119). Read those percentages as the shape of the problem: brushing is not the missing variable — exposure is. That same study’s authors also flag the confounder nobody can remove in cross-sectional designs: athletes who train hard also drink more, breathe through their mouths, and have fewer saliva-rest periods.

Diagnosis: what a dentist measures, and how fast it moves

Erosion is scored, not eyeballed. The index used in the paediatric literature and in the reflux study above is the Basic Erosive Wear Examination (BEWE), which grades severity by sextant (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695) (Ali et al., BMC Oral Health 2026-07-01, PMID 42436443); the wear programme used the Tooth Wear Index and, over the years, intra-oral 3D scanning with surface superimposition for measuring change (Loomans et al., J Dent 2026-07-01, PMID 41946429). The reason to insist on a number is the variation: measured wear rates from 10 to 500 µm per year, with a median patient-level progression of 20–100 µm per year, and large differences between teeth and surfaces of the same mouth (Loomans et al., J Dent 2026-07-01, PMID 41946429). Two patients with the same “look” can be on completely different trajectories — which is precisely why “we will monitor this” is a legitimate clinical decision and not a delay.

What that variation implies about symptoms: sensitivity in worn teeth comes from exposed dentine, and the same programme that measured wear also found direct composite restorations holding up at ≤2.2% annual failure anteriorly and ≤2.9% posteriorly over 5.5 years (Loomans et al., J Dent 2026-07-01, PMID 41946429) — a small, additive, repairable option, and one the patient can afford to try before committing to a full-arch reconstruction.

Treatment, ranked by what the trials actually show

Remove exposure — the part with no evidence of its own

It is embarrassing to say that the most-recommended advice in erosion has the weakest directly measured evidence base: the reviews here recommend dietary modification and risk assessment, and rate the underlying epidemiology as low-to-moderate quality with I² up to 80% (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950) (Juárez López et al., Oral Health Prev Dent 2026-05-01, PMID 42113589) (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695). What exists in the laboratory is the acid-suppression result with calcium additives in an energy drink (Jácome et al., PLoS One 2025-01-01, PMID 41329760) — real chemistry, but no trial of the drink in human mouths with teeth as the endpoint. So: the recommendation to reduce sipping frequency is mechanistically solid and epidemiologically supported, but no randomised trial of “drink less acid, measure less wear” appeared in what we searched.

Chemical protection: fluoride, and the toothpaste question

Fluoride’s role in erosion is to make the surface less soluble — the paediatric review describes fluoride-based agents forming acid-resistant surface layers that reduce enamel and dentine solubility, with combinations with chitosan and other agents under investigation (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695). A 2025 BMC Oral Health study tested whether CPP-ACP and fluoridated toothpastes preserve enamel microhardness after erosion, in a laboratory design of the kind this field uses to make such claims (Al Dehailan et al., BMC Oral Health 2025-10-01, PMID 41063062). Be careful with how far that goes: microhardness in a lab is a surrogate, and the reviews above do not present remineralising pastes as being able to rebuild lost tooth structure. Nothing in the verified material supports “toothpaste grows enamel back” as a claim about a tooth that has already lost surface.

Restoration, when it is needed: less is better

This is the part where the evidence is unusually clear and points against the expensive option. In the pilot randomised trial in severe wear, indirect restorations (polymer-infiltrated ceramic network) survived worse than direct composite over four years: mean annual failure rate 8.7% versus 2.3% (p = 0.008), with failures clustering in the posterior region (p = 0.016), in patients aged 50 or over (p = 0.014), in men (p = 0.017), in people brushing once a day or less (p = 0.008) and in those not cleaning between teeth (p = 0.043); oral health-related quality of life improved after treatment in both arms (Kanaan et al., J Dent 2026-02-01, PMID 41314372). Fifteen patients — this is a pilot, and its p-values should be read with that in mind — but it agrees with the fifteen-year programme’s own finding that indirect molar restorations failed at 8.5–15.5% per year against 3.2–5.4% for the direct approach (hazard ratio 3.37) (Loomans et al., J Dent 2026-07-01, PMID 41946429), and with the two-year trial of opposing wear, where indirect milled overlays were associated with roughly double the enamel wear of direct bulk-fill composite (0.41 ± 0.27 mm versus 0.20 ± 0.05 mm; 22 restorations) (Elhaddad et al., BDJ Open 2026-02-01, PMID 41723141).

The pattern across all three sources is: additive direct composite, repairable and reviewed on a schedule, is the best-evidenced way to rebuild worn teeth; indirect/ceramic full rehabilitation carries a higher failure rate and more wear on the opposing natural tooth, and in the pilot it was also associated with worse survival in exactly the people least able to repeat the procedure. If you are offered “full mouth in six visits”, the evidence-based question is not whether the material is beautiful, but why the smaller option was rejected (Loomans et al., J Dent 2026-07-01, PMID 41946429) (Kanaan et al., J Dent 2026-02-01, PMID 41314372).

Monitor: the option that the long-term data actually support

The Radboud programme’s headline conclusion is that tooth wear is “a predominantly physiological, age-related process”, underpinning a shift toward preventive, risk-based and patient-centred management (Loomans et al., J Dent 2026-07-01, PMID 41946429). With median progression of 20–100 µm per year at patient level (Loomans et al., J Dent 2026-07-01, PMID 41946429), a 25-year-old at the low end of that range will lose roughly 0.2 mm of surface over a decade, and one at the top end about 1 mm — which is a reason to remove the drink and re-scan in three years, not a reason to rebuild the bite now.

What to do, concretely

• Count sipping occasions, not millilitres. The exposure that the reviews associate with damage is frequency and amount of acid contact, not the label (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950). Consolidating drinks to mealtimes is the intervention that follows from the chemistry (Enax et al., Dent J (Basel) 2026-06-01, PMID 42345977).
• Stop the swishing. Anything that lengthens contact time lengthens dissolution. Held-in-mouth drinks, sipping through a straw against the front teeth, and swishing an energy drink “for the fizz” all work against the mechanism, and pH-plus-titratable-acidity data explain why a five-minute exposure already measurably roughens enamel (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138).
• Water afterwards. Saliva has to neutralise a buffered acid; rinsing with water does the same job faster. Nothing in the reviewed literature supports a mouthwash as protection against erosion, and one laboratory study is an argument for not adding one casually: after seven days of immersion in five common products, enamel hardness fell significantly with chlorhexidine (108.28 ± 85.17), Himalaya (104.02 ± 94.22), warm saline (85.42 ± 70.9) and Listerine (55.32 ± 83.68) but not with Colgate Plax; surface roughness rose most with saline and Himalaya, and Listerine produced the greatest colour change (Shanbhag et al., ScientificWorldJournal 2026-01-01, PMID 41913982). Ten extracted teeth per group, in a dish, for fifteen days — that is a caution about a product class, not a trial of erosion treatment.
• On brushing straight after acid: this is the most-quoted rule in the world and I could not find a clinical trial of it in what we searched; the in-vitro erosion-and-abrasion literature exists, but a randomised “wait 30–60 minutes” trial is not in the verified material (Al Dehailan et al., BMC Oral Health 2025-10-01, PMID 41063062). Keep brushing twice a day — in the wear trial, brushing once a day or less was significantly associated with restoration failure (p = 0.008) (Kanaan et al., J Dent 2026-02-01, PMID 41314372).
• Ask about the stomach, the meds and the eating history. Reflux was associated with both more caries and more erosive wear, with lower salivary pH and flow, and the association was strongest in advanced disease (Ali et al., BMC Oral Health 2026-07-01, PMID 42436443); eating disorders were among the significant risk indicators in 5,449 adults (Messias et al., Clin Oral Investig 2026-06-01, PMID 42287456). If wear is on the palatal side of upper teeth, that is a different conversation from a sports drink.
• If you are a heavy user of sports/energy drinks, the same population that needs them for training is the one with 21.2% erosive tooth wear and 63.5% caries prevalence in the athlete study (Khan et al., Nutrients 2022-11-01, PMID 36501119) — so the practical change is the form (dilute, don’t hold, don’t sip for hours), not just the brand.
• Get a baseline and a number. Ask for the severity index (BEWE or a wear index) written in the record, and a re-check with photos or a scan in 12–24 months; the field’s own monitoring data show how much trajectory matters more than appearance (Loomans et al., J Dent 2026-07-01, PMID 41946429) (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695).

How to read this like a clinician

• Record the exposure as frequency, not volume, and separate the two acid sources (extrinsic vs intrinsic) in the note: the association in the adolescent meta-analysis is for a behaviour that is countable (Juárez López et al., Oral Health Prev Dent 2026-05-01, PMID 42113589) (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950).
• Screen the parafunctional and eating-disorder axis explicitly — in the US retrospective study these were as significant as age and sex (Messias et al., Clin Oral Investig 2026-06-01, PMID 42287456), and the airway/bruxism link has its own page in our night-guard article.
• Score severity (BEWE) and rate of change, not impressions; the spread of 10–500 µm/year justifies a monitoring decision for low-rate patients (Loomans et al., J Dent 2026-07-01, PMID 41946429).
• Choose additive direct composite first for rebuilds, and document why an indirect full rehabilitation was chosen if you go there: the pilot RCT and the 15-year programme both favour direct survival (Kanaan et al., J Dent 2026-02-01, PMID 41314372) (Loomans et al., J Dent 2026-07-01, PMID 41946429).
• Do not promise reversal: no verified trial shows a paste restoring lost surface; the fluoride rationale in erosion is solubility reduction, not regrowth (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695) (Al Dehailan et al., BMC Oral Health 2025-10-01, PMID 41063062).
• For children, remember the substrate is more vulnerable: thinner, less mineralised enamel and more soluble dentine (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695) — the threshold for acting on a preschooler’s bottle habit should be low.
• Where the reflux or eating-disorder pathway is active, dental treatment without medical referral fails on exposure, since the acid source is inside the patient (Ali et al., BMC Oral Health 2026-07-01, PMID 42436443).

Cost, coverage, and why the big plan hurts the wallet too

In Utah’s published children’s dental benefit summary (data as of 04 February 2026; see Additional documents), the cheap part is covered and the expensive part needs paperwork. Fluoride treatments including varnish are allowed up to four times per calendar year — which is precisely the agent the paediatric erosion literature recommends as chemical protection against acid dissolution (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695) — and sealants are covered once every two years per tooth on sound first and second permanent molars and premolars. Porcelain-only crowns, by contrast, require prior authorisation, and metal or metal-porcelain crowns are covered on permanent teeth only, with proof of medical necessity and a limit of once every five years per tooth; complete and partial dentures are limited to one upper and one lower every five years, again with prior authorisation. Even imaging has a ceiling: a full set of mouth x-rays, or a panoramic combined with bitewings, is allowed once every two years, and when the full set is billed, no additional individual films are covered at that visit.

The practical translation for erosion: what the payer will fund repeatedly is the low-cost preventive layer (varnish, sealants, reviews), while full rehabilitation is both the out-of-pocket item and, in the trials summarised here, the option with the worse per-tooth survival (Kanaan et al., J Dent 2026-02-01, PMID 41314372) (Loomans et al., J Dent 2026-07-01, PMID 41946429). If an adult is offered “whole mouth in ceramic” as the first move for erosion, the reasonable conversation starts with two questions: what is my measured rate in microns per year, and why is there not an additive direct-composite plan with scheduled review before a ceramic rehabilitation (Loomans et al., J Dent 2026-07-01, PMID 41946429).

What the evidence does not support

• That “sugar-free” or “diet” versions are safe for enamel: in the five-minute exposure study, the sugar-free variants behaved like their sugary counterparts on pH and roughness (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138).
• That occasional energy-drink use is a proven cause of a specific patient’s wear. The best available synthesis is 10 heterogeneous studies with 70% at high or serious risk of bias, and the association is with increased frequency and amount (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950).
• That any toothpaste, serum or powder can rebuild lost enamel surface. The fluoride rationale in erosion is reduced solubility; the remineralising-paste evidence is laboratory microhardness (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695) (Al Dehailan et al., BMC Oral Health 2025-10-01, PMID 41063062).
• That a “waiting time after acid” rule has clinical-trial support: this is the most repeated piece of advice in the field and no randomised trial of it appeared in what we verified (Al Dehailan et al., BMC Oral Health 2025-10-01, PMID 41063062).
• That the ceramic option is the stronger one for worn teeth: the pilot RCT and the 15-year programme both favour direct composite survival, and the RCT found more opposing-enamel wear under indirect overlays (Kanaan et al., J Dent 2026-02-01, PMID 41314372) (Loomans et al., J Dent 2026-07-01, PMID 41946429) (Elhaddad et al., BDJ Open 2026-02-01, PMID 41723141).
• That erosion is mainly a drink problem in midlife adults: in the largest dataset here, age band, sex, parafunction and eating disorders carried the significant associations (Messias et al., Clin Oral Investig 2026-06-01, PMID 42287456).
• That tooth wear always needs treating now: the longitudinal programme frames much of it as physiological age-related change, managed preventively and by risk (Loomans et al., J Dent 2026-07-01, PMID 41946429).

Frequently asked questions

Is my enamel “gone”? Wear is measured in microns per year, and the verified range for patient-level progression is 20–100 µm per year at the median (Loomans et al., J Dent 2026-07-01, PMID 41946429). Ask for your index and your previous photos, and ask what the rate is — not what the impression is.

Does a straw help? The mechanism in the reviewed literature is contact time; the study that produced measurable change used a five-minute immersion (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138). A straw that delivers the drink onto the same surfaces for the same duration is not a protective device, and nothing verified here measured straws.

Should I stop brushing after acid? Do not stop: in the wear trial, brushing once a day or less was significantly associated with restoration failure (p = 0.008) (Kanaan et al., J Dent 2026-02-01, PMID 41314372). The “wait half an hour” rule is common advice without the trial support we could find (Al Dehailan et al., BMC Oral Health 2025-10-01, PMID 41063062).

Are energy drinks worse than soda? On the measured chemistry, Red Bull had the highest titratable acidity of the drinks tested, above Coca-Cola’s, whose pH was the lowest (AlHelal et al., BMC Oral Health 2025-10-01, PMID 41074138). Which one does more damage in whose mouth, over how many years, is not settled: the clinical synthesis is “limited and low-quality evidence” (Luo et al., Dent J (Basel) 2026-06-01, PMID 42345950).

Does my child’s juice habit matter that much? Primary enamel is thinner and less mineralised and the dentine is more soluble, so the exposure produces faster demineralisation than in permanent teeth (Carvalho et al., Eur Arch Paediatr Dent 2026-08-01, PMID 42642695) — and the adolescent pooled association for carbonated drinks is OR 1.98 (Juárez López et al., Oral Health Prev Dent 2026-05-01, PMID 42113589).

Is erosion the same as caries? Same dissolution chemistry, different acid source, and different behaviour of the surface: the same patient can have both, and in the reflux study both were significantly more common (Ali et al., BMC Oral Health 2026-07-01, PMID 42436443) (Enax et al., Dent J (Basel) 2026-06-01, PMID 42345977). Our page on early childhood caries covers the bacterial side.

How this page was built, and what it cannot tell you

Europe PMC was searched for systematic reviews, meta-analyses, randomised trials and large observational studies on dental erosion and tooth wear; each record was then retrieved programmatically with authors, journal, volume, issue, pages, DOI, open-access flag and citation count, and only numbers printed in the fetched abstracts are quoted. Where a review describes its own evidence as low or limited, that adjective travels with the finding. Where a study is a laboratory study, it is labelled as such — this field contains many in-vitro results, and the honest way to use them is as mechanism, not as clinical proof.

What this page cannot tell you: your own wear rate (that needs a baseline index plus a re-measurement, ideally with scans), whether your wear is mainly drinking or mainly reflux or mainly clenching, what your restorations will cost, whether a specific brand is safe, or whether your dentist’s plan for full-arch work is necessary — for that last question the trials here say start additive and reversible, and the rest is judgement about your bite, your money and your tolerance (Loomans et al., J Dent 2026-07-01, PMID 41946429) (Kanaan et al., J Dent 2026-02-01, PMID 41314372).
