Can Acid Reflux Damage Teeth?

Can Acid Reflux Damage Teeth?

Quick Answer

Yes. Stomach acid (pH 2) is highly erosive to tooth enamel. Frequent acid reflux or GERD exposes teeth to acid repeatedly, wearing down enamel over time. The damage is often painless at first and may not be noticed until significant erosion has occurred.

How Does Acid Reflux Damage Teeth?

When stomach acid reaches the mouth — through reflux, regurgitation, or silent GERD — it contacts the enamel on the back surfaces of the upper teeth first. Over time, repeated acid exposure dissolves the mineral structure of enamel.

Enamel erosion on the back surfaces of upper front teeth

This is the classic pattern of acid erosion from GERD — the inner surfaces of the upper front teeth are most exposed to rising stomach acid.

Teeth that appear shorter, thinner, or more translucent

As enamel wears away, teeth lose their natural shape and the translucent dentin layer begins to show through.

Increased sensitivity to hot, cold, and sweet

Enamel loss exposes the dentin, which contains the nerve endings that cause sensitivity.

Rounded or cupped surfaces on back teeth

Acid erosion creates characteristic rounded, smooth depressions on the chewing surfaces of molars and premolars.

How to Protect Your Teeth from Acid Reflux

Rinse with water or a fluoride rinse after reflux episodes. Wait 30 minutes before brushing — brushing immediately after acid exposure can accelerate erosion. Use a prescription-strength fluoride toothpaste. See your dentist more frequently for monitoring and preventive treatments. Reducing acidic foods and drinks — citrus, soda, vinegar, wine — also significantly slows enamel erosion.
