Gastroesophageal reflux disease (GERD) doesn’t just cause heartburn—it can also damage your teeth and gums. When stomach acid repeatedly flows back into the esophagus and reaches the mouth, it can lead to enamel erosion, cavities, and even gum inflammation. If you’re living with GERD, protecting your smile takes more than just brushing and flossing.
What GERD Does to Your Mouth
GERD allows stomach acid to travel up the esophagus, and sometimes it reaches the back of your throat or mouth. This highly acidic fluid wears away the enamel—the outer protective layer of your teeth. Over time, enamel erosion can lead to:
- Increased tooth sensitivity
- Yellowing or transparency of teeth
- Greater risk of cavities
- Bad breath
- Inflamed or irritated gums
Because GERD often happens during sleep, people may not even realize the acid is making its way to their mouth.
Signs GERD Is Affecting Your Oral Health
You might not connect digestive symptoms to dental problems right away. But if you notice any of the following, GERD might be to blame:
- Frequent sour or bitter taste in the mouth
- Dry mouth upon waking
- Thinning or flattening of teeth
- Sensitivity to hot, cold, or sweet foods

How a Dentist Can Help
Your dentist is a key ally in protecting your oral health if you have GERD. Here’s how they can help:
Enamel Monitoring: Regular exams can catch early signs of acid erosion before severe damage occurs.
Fluoride Treatments: In-office fluoride strengthens enamel and helps protect against acid.
Custom Mouthguards: For nighttime reflux, a dentist can create a guard that minimizes acid exposure.
Desensitizing Products: If you’re experiencing pain or sensitivity, your dentist can recommend specific toothpastes or rinses.
Communication with Your Doctor: Dentists can work with your primary care physician or gastroenterologist to coordinate care.
Tips to Protect Your Teeth If You Have GERD
While professional dental care is essential, there are daily habits you can adopt to protect your smile:
Rinse, Don’t Brush Right Away: After reflux episodes, rinse your mouth with water or a baking soda rinse. Wait at least 30 minutes before brushing to avoid scrubbing acid into enamel.
Chew Sugar-Free Gum: This stimulates saliva production, which helps neutralize acid.
Stay Upright After Eating: Avoid lying down for at least 2–3 hours after meals.
Limit Acidic Foods and Drinks: Citrus, tomatoes, coffee, and soda can worsen reflux and harm enamel.
Stay Hydrated: Water helps wash away acid and supports saliva flow.
