People with acid reflux usually notice heartburn first, and few think their teeth are affected too. This article explains why acid erodes teeth and how to protect them every day.
- Stomach acid reaching the mouth can soften and wear down tooth enamel when it happens repeatedly.
- Common signs include sensitivity, thin wear inside the upper front teeth and dented chewing surfaces.
- After reflux, rinse with plain water and wait about 30 minutes before brushing.
- Treating the reflux with a digestive specialist and having regular dental checks both matter.
Why does acid reflux affect the teeth?
During reflux, stomach contents containing acid travel back up the food pipe and can reach the mouth. Enamel is the hard outer layer of the tooth, yet acid softens and slowly dissolves it. When this happens again and again over months or years, enamel becomes thinner and the teeth wear down.
Signs of acid wear
- Teeth that are sensitive to hot, cold or sour food.
- Thin, shiny wear on the inner surface of the upper front teeth.
- Cupped, dented chewing surfaces on the back teeth and edges that seem shorter.
- Teeth that look more yellow because thin enamel lets the dentin underneath show through.
- A sour or bitter taste, especially in the morning, with noticeable breath odour.
These signs can also come from other causes such as brushing too hard or grinding, so a dentist needs to examine you to be sure. You may also read what cervical tooth wear is and what to do about sensitive teeth.
How to protect your teeth during reflux
- Do not brush right after reflux. Acid softens enamel for a while, and brushing straight away can wear it further. Rinse with plain water first, then wait about 30 minutes before brushing.
- Use a soft toothbrush with gentle strokes and a fluoride toothpaste.
- Avoid heavy meals close to bedtime and lying down right after eating.
- Limit fizzy drinks, sour drinks, coffee and alcohol.
- Sip plain water often to wash acid away.
Treat the reflux as well
Dental care only reduces the harm, while the root cause is the reflux itself. Please see a digestive specialist to limit how much acid reaches your teeth. When you visit the dentist, mention that you have reflux so the teeth can be assessed properly.
When should you see a dentist?
Visit a dentist if sensitivity lasts, or if teeth look thin, chipped, discoloured or dented on the chewing surface. If the wear already affects chewing or appearance, the dentist can advise on restoring the teeth with fillings or another suitable option. Regular checks help catch problems early, so see how often a regular dental check is reasonable.

Frequently asked questions
Does acid reflux always wear down the teeth?
Not always. The effect depends on how often reflux happens, your tooth care habits and how hard your enamel is. Proper care lowers the risk.
Should I brush right after reflux?
No. Rinse with plain water first and wait about 30 minutes before brushing, so you do not scrub away enamel that acid has just softened.
Can worn enamel grow back?
Enamel does not fully regenerate. The dentist can advise a filling or other protection for the worn area to reduce sensitivity and further wear.
