How Acid Reflux Affects Your Teeth: What You Need to Know

Introduction

Acid reflux, also known as GERD (gastroesophageal reflux disease), is more than just heartburn—it can also harm your smile. When stomach acid flows back into the mouth, it can erode enamel, increase sensitivity, and raise the risk of cavities. Understanding how acid reflux affects your teeth is the first step in protecting both your oral and overall health.

What Is Acid Reflux?

Acid reflux occurs when stomach acid escapes into the esophagus and sometimes reaches the mouth. The acid has a pH strong enough to dissolve tooth enamel, the protective outer layer of your teeth. Over time, repeated exposure causes dental erosion.

Signs That Acid Reflux Is Affecting Your Teeth

  • Enamel erosion: Teeth may look thinner or more yellow.

  • Increased sensitivity: Cold, hot, or sweet foods may trigger discomfort.

  • Cupping on teeth surfaces: Small dents or pits on chewing surfaces.

  • Higher cavity risk: Weakened enamel makes teeth prone to decay.

  • Bad breath: Acid and food particles contribute to halitosis.

Long-Term Dental Complications

If left untreated, acid reflux can lead to:

  • Severe enamel wear

  • Chipped or fractured teeth

  • Gum inflammation

  • Tooth loss in advanced cases

How to Protect Your Teeth If You Have Acid Reflux

  1. Manage reflux medically – Consult your physician about medications or lifestyle changes.

  2. Neutralize acid – Rinse your mouth with water or a baking soda solution after reflux episodes.

  3. Avoid brushing immediately – Wait at least 30 minutes after acid exposure to prevent brushing softened enamel away.

  4. Use fluoride – Strengthen enamel with fluoride toothpaste or mouth rinses.

  5. Schedule regular dental visits – Dentists can detect early signs of acid erosion and recommend protective treatments like sealants or night guards.

Lifestyle Changes to Reduce Acid Reflux

  • Eat smaller meals and avoid lying down right after eating.

  • Limit acidic foods and drinks (coffee, citrus, soda, alcohol).

  • Maintain a healthy weight.

  • Quit smoking, as it worsens reflux symptoms.

Key Takeaway

Acid reflux doesn’t just affect your stomach—it can damage your teeth over time. By combining medical treatment with smart dental care and lifestyle adjustments, you can protect your enamel, prevent cavities, and maintain a healthy smile.
