What Bulimia Does To Your Teeth Main Effects & Treatment

While many people are familiar with Bulimia, a common eating disorder, many do not know that it can impact a person’s teeth. Bulimia Nervosa, often referred to as Bulimia, is a serious eating disorder that causes a person to eat a large amount of food within a relatively short period of time and then partake in compensatory behaviours, such as vomiting, due to feelings of guilt or shame. These self-induced bingeing episodes can cause serious health concerns and damage a person’s oral health.

Wondering what Bulimia does to your teeth? Keep reading to learn more about the signs of dental damage from Bulimia and how a person’s teeth are affected. In addition, this article will explore potential treatment options for those who have dental damage after suffering from Bulimia.

What Is Bulimia?

Bulimia is a potentially life-threatening mental illness that causes a person to binge after eating an excessive amount of food. People with this eating disorder may also develop other unhealthy habits in an effort to lose weight, such as overusing diuretics or laxatives, excessively exercising, or fasting for prolonged periods of time.

Over time, Bulimia can cause health effects, such as poor nutrition, dehydration, and other mental illnesses. Purging associated with Bulimia, which typically involves vomiting, can cause damage to a person’s teeth and gums. 

Common Signs of Bulimia Dental Damage

Signs of dental damage may occur after frequent vomiting. While signs of dental damage differ from person to person, some of the most common symptoms of what Bulimia does to your teeth include:

  • Enamel Erosion
  • Teeth or gum sensitivity
  • Dry mouth and lips
  • Changes in teeth appearance
  • Discolouration of teeth

How Bulimia Affects Your Teeth

Bulimia can cause oral damage in a variety of ways, which include frequent contact with vomit, excessive tooth brushing, reduced saliva, and poor nutritional intake.

Contact with Vomit

One of the main symptoms of Bulimia is self-induced vomiting. As such, individuals with Bulimia face regular contact with vomit, which contains harsh stomach acids. These stomach acids can cause damage to the teeth, leading to the erosion of enamel. In turn, this can lead to tooth sensitivity and weakening.


After frequent purging, those suffering from Bulimia are likely to brush their teeth. Excessive tooth brushing can lead to tooth abrasion and enhanced tooth sensitivity.

Reduced Saliva

Some people with Bulimia may also overuse laxatives to help lose weight. Abusing laxatives can lead to severe dehydration, which reduces the amount of saliva production in the mouth. Too little saliva can leave your teeth unprotected and more susceptible to damage.

Poor Diet

Those struggling with eating disorders like Bulimia often become deficient in important nutrients. A poor diet can negatively impact oral health.

Bulimia Teeth Treatment

Bulimia can cause dangerous health effects on both your body and mouth. If you suffer from Bulimia, early treatment is recommended to help prevent permanent oral damage.

Our expert Bellevue Hill Dental staff are well informed on what bulimia does to your teeth and can help you create the best hygiene program for your needs.

Bellevue Hill Dental offers dental crowns to address tooth erosion from Bulimia. This can be a great treatment option for those who have weakened teeth as a result of frequent purging. We offer several different types of dental crowns, including ceramic, porcelain, and metal alloy crowns.
