## How gastric acid affects tooth enamel

Gastroesophageal reflux disease, widely known as GORD in the UK or GERD in North America, occurs when stomach acid repeatedly travels up the oesophagus and into the mouth. Gastric acid has a very low pH — typically around 1.5 to 3.5 — which is corrosive to tooth enamel. Each episode of reflux bathes the teeth in acid, and over time this dissolves the mineral content of the enamel surface in a process called acid erosion. The pattern of erosion caused by GORD is clinically distinctive. Because stomach acid is regurgitated upward and pools at the back of the mouth, the teeth most heavily affected are the palatal surfaces of the upper teeth — the surfaces that face the tongue and roof of the mouth — and the lingual surfaces of the lower posterior teeth. The erosion pattern is smooth and cupped, and in advanced cases the biting surfaces of the back teeth become flattened and glassy. This is different from dietary acid erosion, which tends to affect labial and buccal surfaces more uniformly.

## How enamel erosion weakens orthodontic bonding

Fixed orthodontic brackets are bonded directly to the enamel surface using dental adhesive. The bond relies on a micro-mechanical interlocking of adhesive into the enamel surface following acid etching. When enamel has already been eroded by gastric acid, the surface is chemically altered in ways that can reduce the reliability of this bond. Eroded enamel is softer, thinner, and may have a different mineral density from healthy enamel. This means that even after etching during bracket placement, the adhesive may not achieve the same bond strength as it would on pristine enamel. In practice this can increase the risk of bracket debond during treatment, which requires unscheduled appointments to rebond the bracket and may temporarily set treatment back. Orthodontists working with patients who have active or poorly controlled GORD may choose to use a more resilient adhesive system or increase monitoring frequency during treatment.

## Effect of enamel erosion on clear aligner fit

For patients using clear aligners such as Invisalign or other thermoplastic appliance systems, enamel erosion presents a slightly different problem. Clear aligners are fabricated from a precise digital or physical scan of the teeth. The aligner fits tightly over the tooth surfaces and relies on that close adaptation to transmit the planned orthodontic forces. When enamel surfaces are thinned or irregular due to acid erosion, the topography of the teeth changes — in some cases gradually and progressively during the course of treatment itself. This can mean that aligners fabricated early in treatment no longer fit the teeth accurately by the time they are worn, leading to tracking issues where teeth do not move as planned. Attachments — small composite bumps bonded to the teeth to help aligners grip — may also debond more readily from eroded enamel surfaces.

## Protective measures during reflux episodes

Managing reflux carefully during orthodontic treatment helps reduce further enamel damage. After any reflux episode, the instinct is to brush the teeth immediately, but this is counterproductive. When enamel is softened by acid it is temporarily more vulnerable to abrasion, and brushing in this state actually removes more enamel than if you wait. Instead, immediately after reflux, rinse the mouth thoroughly with plain water to dilute and neutralise the acid. A fluoride mouthwash or a mouth rinse made with a small amount of bicarbonate of soda in water can further help neutralise acidity. Avoid brushing for at least 30 to 60 minutes after a reflux episode to allow the enamel to remineralise and harden before being subjected to toothbrush abrasion. This guidance is counterintuitive for many patients who associate brushing with cleanliness, so it is worth discussing explicitly with your orthodontic team.

## Importance of controlling GORD before starting treatment

While it is possible to undergo orthodontic treatment with reflux, the outcome is likely to be more predictable if GORD is well controlled before braces or aligners are fitted. Active, frequent reflux throughout treatment means that enamel is continuously being weakened, brackets or aligners are performing on a substrate that is deteriorating, and the risk of significant enamel loss by the end of treatment — which may be 18 to 24 months or more — is higher. Ideally, GORD should be assessed and managed by a general practitioner before orthodontic treatment begins. In mild cases, dietary and lifestyle modifications may be sufficient. In moderate to severe cases, proton pump inhibitor medication is highly effective at reducing gastric acid production and can make a substantial difference to the enamel protection available during treatment.

## Medications and coordination with your GP

Proton pump inhibitors such as omeprazole and lansoprazole are commonly prescribed for GORD and are generally very effective. If you have been prescribed PPI medication but are not taking it consistently, resuming regular use before and during orthodontic treatment is strongly advisable. If you have not yet sought medical advice for acid reflux symptoms, your GP is the appropriate first contact. In cases where reflux is caused or worsened by other conditions such as hiatus hernia, obesity, or pregnancy, addressing those underlying factors as far as possible will help. Your orthodontist does not prescribe medication for GORD, but they can write to your GP with a supporting letter explaining the orthodontic context if that would assist you in accessing treatment promptly.

## What to disclose at your consultation

When attending an orthodontic consultation or beginning a course of treatment, always disclose acid reflux or GORD symptoms even if they seem mild or infrequent. The orthodontist will examine the teeth for signs of erosion and may refer you back to your GDP or GP if significant enamel loss is observed. Information about how frequently you experience reflux, whether it is managed with medication, whether you have nocturnal symptoms — reflux during sleep is particularly damaging because there is less saliva to buffer acid — and whether you have had any previous advice about enamel erosion is all relevant to treatment planning. Patients sometimes feel embarrassed to mention GORD, particularly if it is associated with dietary habits, but this information genuinely affects the choice of treatment, the adhesive systems used, and the monitoring approach throughout your care.

## Dietary triggers and drinks to avoid during treatment

Many dietary factors that trigger or worsen acid reflux also pose additional risks to teeth during orthodontic treatment. Carbonated drinks — including sparkling water, fizzy juices, and diet soft drinks — are both acidic and carbonated, delivering acid directly to the tooth surfaces and compounding the erosive effect of gastric acid. Citrus fruits and juices, vinegar-based dressings, and highly acidic foods such as pickles and fruit teas erode enamel directly through their own acidity. Alcohol relaxes the lower oesophageal sphincter and promotes reflux. Coffee and chocolate are also common reflux triggers. Reducing or eliminating these foods and drinks during orthodontic treatment is sensible advice for anyone with a history of acid erosion, regardless of whether they have a formal GORD diagnosis. Drinking water throughout the day helps keep the oral pH closer to neutral and maintains salivary flow, which is the mouth's own natural buffering and remineralisation system.

## Monitoring during your orthodontic appointments

Your orthodontist should monitor tooth surfaces for signs of erosion progression throughout treatment. At each adjustment or review appointment, the teeth can be visually assessed for changes in surface texture, loss of surface detail, changes in colour and translucency at the biting edges, and any alteration in the way brackets or aligners are fitting. Photographs taken at the start of treatment provide a baseline for comparison. If significant erosion is noted to be progressing during treatment, the orthodontist may recommend a pause while GORD management is reassessed, a referral for restorative assessment, or an accelerated monitoring plan. In some cases high-concentration fluoride varnish applications at appointments can help remineralise and harden vulnerable enamel surfaces. Early identification of deteriorating enamel means problems can be addressed before they cause irreversible structural damage.

### Frequently Asked Questions

Can I have braces if I have acid reflux?

Yes, orthodontic treatment is possible with acid reflux, but GORD should be as well controlled as possible before and during treatment. Poorly managed reflux weakens enamel, reduces bracket bond reliability, and can affect aligner fit. Disclose your symptoms at your consultation so the orthodontist can plan accordingly.

Should I brush my teeth immediately after reflux?

Wait before brushing. Stomach acid temporarily softens the surface of the enamel, and brushing straight away scrubs away that softened layer, which over time causes more erosion than the reflux alone would. Rinse instead — plain water, a fluoride mouthwash, or a small amount of water with a pinch of bicarbonate of soda to neutralise the acid — then leave at least 30 to 60 minutes before brushing, giving saliva time to reharden the enamel through remineralisation. If you wear clear aligners, do not put them back in immediately after an episode; rinse first, so acid is not held against the teeth under the tray.

Will GORD make my brackets fall off?

Enamel eroded by chronic acid exposure can reduce bracket bond strength, increasing the likelihood of debonds compared with healthy enamel. Controlling reflux with medication and good dietary management reduces this risk. Your orthodontist can use adhesive systems suited to enamel that has experienced some erosion.

Does acid reflux affect Invisalign?

Yes. Thinned or eroded enamel changes the tooth surface topography, which can affect aligner fit over time. Aligners and attachments may also be harder to bond to eroded enamel. Controlling GORD before and during Invisalign treatment helps maintain predictable tracking.

Should I see my GP before starting braces if I have reflux?

It is advisable. If your reflux is undiagnosed or poorly managed, starting with a GP appointment to explore treatment options — including proton pump inhibitors — before orthodontic treatment begins is sensible. Your orthodontist can support this with a letter explaining the clinical context if needed.

Can wearing aligners overnight make reflux damage worse?

It is a reasonable concern and worth raising. An aligner covers the biting and inner surfaces of the teeth, so if reflux occurs at night the acid can be held against the enamel under the tray rather than being diluted and cleared by saliva. Nobody should stop wearing prescribed aligners on this basis, but it is a good reason to have the reflux itself managed properly, to avoid eating late, and to rinse with water before inserting the trays. Where erosion is already established, the orthodontist and your GP or gastroenterologist should be aware of each other's plans.
