When most people think of acid reflux, they picture heartburn or a sour taste in the mouth after a heavy meal. But did you know that acid reflux can also affect your teeth? It’s true, and it’s something we see in our dental clinic more often than you might think. If you suffer from GERD (Gastroesophageal Reflux Disease) or frequent acid reflux, your oral health could be at risk even if you brush and floss daily.
Let’s break down how this happens—and what you can do about it.
What Is Acid Reflux and Why Does It Matter for Your Mouth?
Acid reflux happens when stomach acid flows back into the esophagus and sometimes even into the mouth. That acid is strong—it’s meant to break down food in your stomach. But when it reaches your teeth, it starts doing damage. It softens your enamel (the outer shell of your teeth), making it easier for cavities to form and teeth to wear down. Over time, this can lead to tooth sensitivity, discoloration, and even cracking or chipping.
How Do You Know Acid Reflux Is Affecting Your Teeth?
Sometimes the signs are subtle. You might notice:
- Sensitivity to hot, cold, or sweet foods
- A yellowing of the teeth (thinned enamel shows more dentin)
- Chips or rough edges on your molars
- A sour taste in your mouth, especially in the morning
- Frequent cavities, even with good oral hygiene
If these sound familiar and you also deal with acid reflux, it might be time to chat with both your dentist and your doctor.
How Does Acid Damage Work?
Much like sugar-related decay, acid from your stomach lowers the pH level in your mouth. A lower pH means more acidity, which weakens enamel. Your enamel can’t regrow once it’s gone—it’s a protective barrier, and when it wears away, your teeth are exposed to decay and sensitivity.
Think of it this way: each acid reflux episode is like a mini acid bath for your teeth. It may not seem like much at first, but over time, it adds up.
What Can You Do to Protect Your Teeth from Acid Reflux?
The good news is that you can protect your smile, even if you’re managing acid reflux. Here are a few tips:
- Don’t brush immediately after reflux. Acid softens your enamel, so brushing right after can cause more wear. Wait at least 30 minutes.
- Use fluoride toothpaste. This helps strengthen enamel and prevent erosion.
- Stay hydrated. Saliva is your mouth’s natural defense against acid. Drink plenty of water and avoid dry mouth triggers like alcohol or caffeine.
- Rinse with water or baking soda. After an episode of reflux, swish with water or a mild baking soda solution to neutralize the acid.
- Talk to your doctor. Managing the reflux itself with diet changes or medication can make a big difference in protecting your teeth long-term.
