Enamel Erosion
Acid Wear
Enamel erosion is the gradual loss of the tooth's protective outer layer, often caused by repeated exposure to acids rather than bacteria. The process may develop slowly over time, and individuals may notice changes in tooth appearance or sensitivity. A professional dental assessment can help identify the cause and determine appropriate management.

Understanding the Condition
What Is Enamel Erosion?
Enamel erosion — also known as acid wear or dental erosion — refers to the chemical dissolution of tooth enamel caused by direct exposure to acids. Unlike tooth decay, which is driven by acid-producing bacteria in dental plaque, erosion results from acids in the diet, the stomach, or the environment acting directly on the tooth surface.
As the enamel is gradually worn away, the tooth loses its protective outer layer. The underlying dentine — which is softer and naturally yellower — becomes more exposed, leading to changes in tooth appearance and increased sensitivity. Importantly, once enamel is lost it does not naturally regenerate, making early detection and prevention particularly valuable.
Enamel erosion can affect anyone, but certain dietary habits, medical conditions and lifestyle factors can increase the risk. A professional dental assessment can help identify the extent of any erosion, determine contributing factors, and develop a personalised plan to help protect remaining enamel and restore affected teeth where appropriate.
Symptoms & Signs
Increased tooth sensitivity
As enamel thins, the underlying dentine becomes more exposed, leading to heightened sensitivity to hot, cold, sweet or acidic stimuli
Yellowing of teeth
As the white enamel layer wears away, the naturally yellower dentine beneath becomes more visible, giving teeth a darker or more yellow appearance
Smooth or shiny surfaces
Eroded enamel often develops an unusually smooth, glossy or glass-like appearance, particularly on the front surfaces of the teeth
Rounded or worn edges
The biting edges of front teeth and the cusps of back teeth may appear flattened, rounded or slightly translucent as enamel is progressively lost
Cupping or indentations
Small, shallow depressions or cup-shaped defects may appear on the biting surfaces of back teeth where enamel has been dissolved away
Enamel erosion often develops gradually and may not be noticeable until significant wear has occurred. Regular dental examinations help detect changes at an early stage.
Contributing Factors
Common Causes of Enamel Erosion
Enamel erosion results from repeated or prolonged exposure to acids. Several factors can contribute, and in many cases more than one cause is involved.
Acidic foods and drinks
Frequent consumption of citrus fruits, fizzy drinks, wine, sports drinks and vinegar-based foods exposes enamel to repeated acid attacks, gradually dissolving its mineral content
Acid reflux or gastric conditions
Gastro-oesophageal reflux disease (GORD), frequent vomiting or other conditions that bring stomach acid into the mouth can cause significant and characteristic enamel erosion
Dry mouth (xerostomia)
Reduced saliva flow diminishes the mouth's ability to neutralise acids and support remineralisation, leaving enamel more vulnerable to chemical wear over time
Certain medications
Some medications — including aspirin, antihistamines and vitamin C supplements — can be acidic or reduce saliva flow, contributing to an oral environment that accelerates erosion
Environmental or occupational exposure
Individuals regularly exposed to acidic environments — such as professional wine tasters, swimmers in chlorinated pools or certain industrial workers — may experience increased enamel wear
Dietary habits over time
The cumulative effect of long-term dietary patterns matters more than individual episodes — frequent snacking, prolonged sipping and holding acidic drinks in the mouth all increase risk
Why It Matters
Potential Risks if Not Addressed
Because enamel cannot regenerate once lost, erosion that continues unchecked leads to progressive and irreversible thinning of the tooth's protective layer. Over time, this exposes increasingly more dentine, leading to heightened sensitivity and a greater risk of further damage.
As teeth become thinner and weaker, they are more susceptible to chipping, cracking and fracture. The edges of front teeth may become translucent and fragile, while the biting surfaces of back teeth can develop significant cupping and wear. These changes can affect both the function and appearance of the teeth.
In advanced cases, the extent of enamel loss may require restorative treatment — such as composite bonding or dental crowns — to rebuild tooth structure, restore function and protect the remaining tooth. Identifying and managing erosion at an earlier stage can help reduce the likelihood of needing more extensive intervention.
Your Options
Treatment & Preventive Options
Management of enamel erosion depends on the extent of wear and the contributing factors involved. A personalised approach — combining preventive care with restorative treatment where needed — is recommended.
Fluoride Treatments
Professional fluoride applications help strengthen remaining enamel by promoting remineralisation and increasing resistance to future acid attacks.
Learn MoreDietary Advice
Tailored guidance on reducing the frequency and impact of acidic food and drink consumption, helping to slow or prevent further erosion.
Learn MoreComposite Bonding
Tooth-coloured composite resin can be applied to worn or damaged surfaces to restore shape, protect exposed dentine and improve appearance.
Learn MoreDental Crowns
Where erosion is more advanced, crowns can provide comprehensive protection and restore the structure, function and appearance of significantly worn teeth.
Learn MoreManagement of Underlying Conditions
Where acid reflux or other medical conditions contribute to erosion, coordinated management with your GP helps address the source of acid exposure.
Learn MoreMonitoring & Review
Regular review appointments allow your dentist to track the progression of erosion, assess whether preventive measures are effective, and adjust care as needed.

Importance of Professional Dental Assessment
Enamel erosion may not be immediately noticeable to patients, as the changes can develop gradually over months or years. A professional examination allows your dentist to identify both early and more advanced stages of erosion — often before significant symptoms have developed — and to distinguish it from other forms of tooth wear or decay.
During your assessment, your dentist will examine the pattern and distribution of wear across your teeth, review your dietary and medical history to identify potential contributing factors, and may use X-rays or other investigations where appropriate. Understanding the cause is essential, as effective management requires addressing the source of acid exposure as well as the resulting damage.
Based on the findings, a personalised plan will be developed. This may include preventive measures such as fluoride treatments and dietary advice, professional cleaning, protective restorations where teeth are significantly affected, and coordination with your GP if gastric conditions are involved. Regular review appointments allow your dental team to monitor any progression and adjust care as needed.
