How Does Bulimia Affect My Teeth?

Eating disorders like bulimia take a toll on overall health, but one of the most visible—and often overlooked—effects is on your teeth and gums. “Your teeth tell a story, and for those struggling with bulimia, that story often involves serious damage,” says Dr. Mas’ood Cajee, DDS, MPH, a Manteca dentist. Here are five ways bulimia impacts oral health and what you can do about it.

1. Enamel Erosion – Frequent vomiting exposes teeth to stomach acid, wearing away enamel and leading to sensitivity and yellowing. Rinsing with water (not brushing immediately) can help neutralize acids.

2. Cavities & Decay – With weakened enamel, bacteria attack more easily, increasing cavities. Fluoride treatments can strengthen teeth and slow decay.

3. Gum Disease – Nutritional deficiencies and acid exposure can cause inflamed, bleeding gums. A balanced diet and professional cleanings are key.

4. Dry Mouth – Dehydration from purging reduces saliva, which protects against bacteria. Drinking water and using sugar-free gum can help.

5. Sore Throat & Soft Tissue Damage – Repeated vomiting can lead to chronic throat irritation and even sores in the mouth. Seeking professional help is the first step to healing.

If you or someone you know is struggling with bulimia, a dentist can be part of the recovery team. Your smile—and your health—deserve care.
