Bulimia and effects on teeth


Repeated vomiting can cause serious damage to the teeth.

Bulimia is an eating disorder in which people binge-eat large amounts of food, then they throw up, fast, or engage in some other behavior such as using laxatives or exercising to excess to rid their bodies of all the extra calories.

Vomit is especially toxic because it contains stomach acids. The acids can wear away the enamel that covers and protects your teeth. Brushing your teeth too hard after you vomit can also contribute to tooth erosion and tooth decay.

Dental conditions associated with bulimia:


Yellow teeth


Swollen salivary glands

Mouth sores

Dry mouth and pain


If the teeth have been worn out by the acidity of frequent vomiting, a composite filling is recommended in order to cover the exposed dentin and replace the missing enamel structure.

Frequent visits to the dental office and the use of fluoridated toothpaste are also crucial. For the protective effect of fluoride see our future blogs

In some extreme cases a full-coverage ceramic crown is necessary.



Before: Eroded Enamel with exposed dentin

After: Dentin covered with a composite restoration
