How Acid Reflux (GERD) Impacts Your Oral Health

Acid Reflux (GERD) Treatment

Heartburn—often described as a burning sensation in the chest or throat—is something many Canadians experience. Known medically as acid indigestion, this condition can be a symptom of gastroesophageal reflux disease (GERD), a chronic disorder that affects not only your digestive system but also your teeth and gums.

What Is Acid Reflux and GERD?

Acid reflux occurs when the muscles at the bottom of your esophagus relax, allowing stomach acid to flow upward into the throat and mouth. These acids irritate and inflame the tissues they touch. When reflux happens frequently, it develops into GERD, a more serious condition where stomach acid continuously moves upward, leading to damage of the esophagus lining and persistent discomfort.

Causes & Symptoms to Acid Reflux (GERD)

Common Signs and Symptoms

While GERD can sometimes be hard to detect, there are several symptoms to watch for:

  • Persistent heartburn or burning in the chest
  • Difficulty swallowing
  • Chronic coughing or sore throat
  • Nausea or vomiting
  • Regurgitation or bad breath
  • Tooth enamel erosion or sensitivity
  • Chipping and discolouration of teeth
Stomach acid has an extremely low pH—often below 2.0—which can rapidly erode tooth enamel. Enamel begins to break down in environments with a pH of 5.5 or lower, leaving teeth vulnerable to sensitivity, decay, and cosmetic damage. Left untreated, GERD can also increase your risk of developing esophageal cancer.

Treatment and Lifestyle Modifications

GERD is typically diagnosed through tests such as pH monitoring, endoscopies, or X-rays. Although it’s a chronic condition, symptoms can be managed with a combination of medications and lifestyle changes, including:

  • Taking over-the-counter antacids or H2 blockers
  • Losing excess weight
  • Avoiding tight clothing
  • Not eating 2–3 hours before bed
  • Limiting trigger foods (chocolate, coffee, alcohol, spicy foods)
  • Quitting smoking

How to Protect Your Teeth from Acid Reflux

Maintaining good oral hygiene is essential, but patients with GERD can take additional steps to reduce enamel damage:

  • Visit your dentist regularly for enamel and gum evaluations
  • Use toothpaste formulated for sensitive teeth
  • Wait at least one hour before brushing after acidic foods
  • Rinse with water or baking soda after reflux episodes
  • Ask your dentist about professional fluoride treatments
  • Wear a custom mouthguard to protect enamel from acid exposure
