Can acid reflux damage teeth?
Yes. When stomach acid repeatedly reaches the mouth, it dissolves tooth enamel, a process called dental erosion. Reflux typically affects the inner surfaces of the upper teeth and the chewing surfaces of the back teeth, and causes sensitivity, yellowing and thin, glassy edges. The lost enamel does not grow back. At Creative Arts in Dubai, dentists look for these patterns, advise on protection and repair worn teeth once the reflux is managed.

Why is stomach acid so hard on teeth?
Enamel starts to dissolve when the mouth becomes acidic, and stomach acid is far stronger than the acid in most food and drink. With reflux it can reach the back of the mouth many times a day, often without much warning. The American Dental Association notes that reflux can wear away enamel on the inside surfaces and chewing surfaces of the teeth, and that the damage is worse during sleep, when you swallow less often and saliva, the mouth's natural buffer, slows down.
The pattern is what gives reflux away. Acid rising from the throat washes first over the inner, tongue-side surfaces of the upper front teeth and the chewing surfaces of the molars, areas that food acids and toothbrushes affect less. Erosion from soft drinks and citrus tends to show on the outer front surfaces instead.
Some people have reflux without heartburn, sometimes called silent reflux. In those cases a dentist may be the first to notice the signs, and the right next step is a visit to your doctor as well as dental protection.
What are the signs of acid erosion on teeth?
Early erosion is easy to miss because it often causes no symptoms at first and starts on surfaces you cannot see in the mirror.
| What you might notice | What the dentist sees | Why it happens |
|---|---|---|
| Teeth twinge with cold, hot or sweet drinks | Exposed dentine where enamel has thinned | Dentine has tiny channels running towards the nerve |
| Front teeth look more yellow | Thin enamel letting yellower dentine show through | Enamel is translucent; the less there is, the more dentine shows |
| Edges of front teeth look see-through or chip | Thin, glassy incisal edges | Acid thins the edge from behind; see translucent tooth edges |
| Back teeth look flatter or have small craters | Cupped hollows on the chewing surfaces | Softened enamel wears quickly under chewing |
| Fillings feel higher than the tooth | Fillings standing proud of the tooth around them | Tooth around the filling dissolves; the filling does not |
| Inner surfaces of upper teeth feel smooth or shiny | Smooth, glazed surfaces with rounded edges | Classic reflux pattern on the tongue side |
Any of these can have other causes. A dental examination, sometimes with photographs or scans to compare over time, confirms erosion.
Reflux erosion or another kind of tooth wear?
Most worn teeth have more than one cause. Where the wear sits is the main clue.
| Type of wear | Typical location | Look |
|---|---|---|
| Reflux or vomiting erosion | Inner surfaces of upper teeth; chewing surfaces of molars | Smooth, glassy, rounded |
| Dietary erosion | Outer surfaces of front teeth | Smooth, scooped, sometimes yellow |
| Grinding (attrition) | Biting edges and chewing surfaces | Flat, matching facets on upper and lower teeth |
| Brushing wear and notches | Necks of teeth at the gum line | Wedges or grooves; see notches at the gum line |
Our page on worn teeth covers all types of wear and how each is managed.
Should I brush after vomiting or reflux?
Not straight away. Acid leaves the enamel surface temporarily softened, and brushing at that moment can scrub away more of it. A gentler routine works better:
- Rinse first with plain water to wash the acid away and dilute what is left.
- Chew sugar-free gum if you can; the ADA notes that it encourages saliva, which helps neutralise and wash away acid.
- Wait before brushing, ideally around an hour, so saliva can begin to reharden the surface.
- Brush gently with a soft brush and a fluoride toothpaste, and avoid whitening or very abrasive pastes.
The same logic applies after acidic food and drink. Our guide on whether to brush right after eating explains the timing in more detail. If vomiting is frequent for any reason, including pregnancy sickness or an eating disorder, tell your dentist and doctor: support is available and the teeth can be protected.
How can you protect your teeth from acid reflux erosion?
Protecting the teeth means tackling the acid at its source and making the enamel more resistant at the same time.
- Treat the reflux with your doctor. The dental side is only half the answer. The ADA advises working with a physician on the underlying problem.
- Leave a gap between eating and lying down. The ADA notes that not eating for about three hours before bed may reduce reflux episodes. This matters at iftar and suhoor during Ramadan, when large meals are often followed by sleep; see our guide to dental care in Ramadan.
- Use fluoride every day. A fluoride toothpaste, spat out but not rinsed away, helps the surface resist acid. Your dentist may apply fluoride varnish or recommend a desensitising or higher-strength toothpaste where appropriate.
- Cut down acid contact in your diet. Keep acidic drinks to mealtimes, drink them chilled and quickly, ideally with a straw, rather than sipping for long periods.
- Watch for dry mouth. Some reflux and other medicines reduce saliva. Our page on dry mouth explains what helps.
- In pregnancy, reflux and sickness are common; our guide to dental care during pregnancy covers safe check-ups.
When reflux needs a doctor soon
See a doctor promptly if you have difficulty or pain swallowing, unexplained weight loss, persistent vomiting, vomit containing blood, or black stools, or if heartburn is frequent and not settling with simple measures. Chest pain that could be cardiac, or vomiting blood, needs a hospital emergency department. Your dentist can record the dental signs and share them with your doctor if you wish.

Explore restorative dentistryHow are teeth eroded by acid reflux repaired?
Treatment starts with the least invasive option that protects the tooth, and only once the acid is being controlled.
| Stage of erosion | Usual approach | Notes |
|---|---|---|
| Early: enamel thinning, no symptoms | Prevention, fluoride, monitoring with photos or scans | The aim is to stop further loss |
| Sensitive teeth, dentine exposed | Desensitising care, fluoride varnish, sometimes a thin bonded composite layer | Covers the dentine; see sensitive teeth |
| Moderate loss on the inner or chewing surfaces | Bonded composite to rebuild the lost surfaces | Adds tooth back rather than removing more |
| Front teeth thin, short or chipped | Composite bonding or porcelain veneers, after design | Chosen to suit the bite and appearance |
| Severe loss, bite height reduced | Crowns and a planned full mouth rehabilitation | Restorations made in the dental lab in our building |
If reflux continues untreated, restorations can be undermined at their edges, so dental repair and medical treatment go together.
Who checks and repairs eroded teeth at Creative Arts?
At Creative Arts in Dubai, Dr. Marina Antoniuk and Dr. Julia examine worn and sensitive teeth and carry out conservative repairs, and Dr. Khalid Saeed, co-founder of the clinic, plans larger rebuilds such as crowns and full mouth rehabilitation. Each plan is written and itemised, with the options from simplest to most involved, and it explains what needs to happen with the reflux itself before any major restorative work.
At a first erosion check, the dentist records where the wear is, how sensitive the teeth are and how your teeth meet, and may take photographs or an intraoral scan as a baseline. Comparing these at later visits shows whether the wear has stopped, which matters more than any single appointment.
