Eating disorders are often hidden struggles, but their effects on oral health are hard to miss. While most people associate conditions like bulimia or anorexia with weight changes or nutritional deficiencies, the damage to your teeth and gums can be just as serious, and sometimes irreversible.
In this blog, you will learn how eating disorders impact the mouth, which symptoms to watch for, and how early dental care can help protect your long-term oral health.

Key Takeaway
Eating disorders silently damage your teeth through acid erosion, dry mouth, and nutritional deficiencies. But with the right dental treatment, you can prevent further harm and start rebuilding a healthy, strong smile, no matter where you are in your journey.
Why Eating Disorders Damage Teeth
Disordered eating harms teeth in several ways. It is not just about what is missing from the diet, but also about what the mouth is exposed to.
1. Acid erosion from vomiting: When a person purges, stomach acid flows over the teeth. This acid is powerful enough to dissolve enamel, the protective outer layer of the tooth. This process, known as erosion of tooth enamel, leads to tooth sensitivity, discoloration, cavities, and possibly tooth loss.
2. Nutritional deficiencies weaken oral tissues: A lack of vitamins A, C, D, calcium, iron, and protein can weaken the gums and bones that support the teeth. These nutritional deficiencies increase the risk of tooth decay, gum recession, and infections. Studies highlight that anorexic patients often show significant dental complications even in early stages.
3. Chronic dry mouth: Dehydration, food restriction, and medications used in treatment often reduce saliva production, leading to dry mouth. Without enough saliva to protect against gastric acid and bacteria, tooth erosion and gum disease progress more rapidly.
4. Excessive sugar or acidic food intake: Some eating disorders involve binge eating on acidic foods or sweets, which also contribute to enamel erosion. Combined with frequent vomiting, the stomach acids can accelerate breakdown of both hard and soft tissues in the mouth.
Signs of Eating Disorder-Related Tooth Damage
If you are living with an eating disorder, your mouth might be showing signs of it, often before you even realize the connection.
Pay close attention to these oral symptoms and know that you can speak with your dentist openly and without shame.
- Sensitive teeth or sharp reactions to hot, cold, or sweet foods
- Eroded enamel that looks glassy, smooth, or yellow
- Tooth pain or cracked teeth from weakened surfaces
- Dry mouth and bad breath that will not go away
- Bleeding gums or gum recession
- Swollen salivary glands (especially in bulimia)
- Delayed healing after dental work or mouth sores
These symptoms reflect compromised oral health and should be assessed by an experienced dental professional or dental hygienist.

FAQs
A dentist can often identify signs of an eating disorder through symptoms like enamel erosion, dry mouth, gum issues, and sensitive or damaged teeth. These oral signs often appear before medical symptoms become obvious.
Tooth damage from bulimia can begin within weeks of frequent purging. The more frequent the exposure to stomach acids, the faster tooth enamel breaks down. Without intervention, the damage can become severe and permanent.
Unhealthy eating habits, especially diets high in sugar, acidic foods, or low in essential nutrients, increase the risk of tooth decay, gum disease, and enamel erosion. Combined with poor oral hygiene, it can lead to long-term oral health issues.
