Posted on 6/16/2025 by Singing River Dentistry - Helton Drive |
 We all have different relationships with food. Some of us love to cook, some of us love to eat, and some of us avoid it as much as possible. While it’s common to have different eating styles, it can become problematic when our relationship with food starts to negatively affect our health and well-being.
Eating disorders impact a person's physical, mental, and social health. It can affect one or more body systems, including the mouth. Many eating disorders involve behaviors that can significantly damage the teeth and gums.
This article aims to raise awareness about the effects of eating disorders on oral health. By understanding these impacts, those struggling with eating disorders or those who know someone who is, can seek help for both the eating disorder and the resulting dental complications.
It’s important to note that this article does not replace professional guidance. If you think you or someone you know might have an eating disorder, don’t hesitate to seek help from a healthcare professional or mental health professional.
How Eating Disorders Affect Oral Health
Eating disorders manifest in different ways, and each can have different consequences for the health of the mouth.
Bulimia is characterized by recurrent episodes of binge eating followed by purging. Purging may involve self-induced vomiting or the use of laxatives or diuretics. Vomiting frequently exposes teeth to stomach acid, which erodes tooth enamel, leading to sensitivity, staining, and cavities. Laxatives and diuretics can reduce saliva production, leading to dry mouth, which exacerbates the problem by making your mouth more acidic and washing away protective minerals from your teeth.
Anorexia nervosa, characterized by severe calorie restriction and an overwhelming fear of weight gain, can also cause damage to the mouth. Malnutrition from inadequate food intake weakens teeth and makes them susceptible to erosion and cavities. Additionally, persistent dehydration from a lack of fluids can lead to dry mouth, increasing the risk of dental problems.
Restoring Your Mouth After an Eating Disorder
The good news is that, with proper treatment for both the eating disorder and the resulting dental damage, most patients with eating disorders can regain their oral health.
Restorative dentistry offers various treatments to repair and improve the appearance of damaged teeth. These may include:
| • |
Fillings to repair cavities |
| • |
Crowns to protect and strengthen weakened teeth |
| • |
Bonding for chipped or broken teeth |
| • |
Teeth whitening to address staining |
While restoring the function and aesthetics of your teeth is important, taking care of your oral health in the present and future is equally crucial. This includes brushing your teeth twice daily using fluoride toothpaste, flossing at least once daily, and visiting your dentist regularly for cleanings and check-ups.
Taking Steps To Recovery
If you suspect you have an eating disorder or have noticed changes in your oral health that may be related to your eating habits, seeking professional help is essential. Early diagnosis and treatment can prevent serious complications and help you regain your physical, mental, and oral health.
Your dentist plays a valuable role in your eating disorder recovery journey. By identifying oral health problems, your dentist can inform treatment options and provide necessary dental care to restore your smile. Additionally, dental care professionals are often the first medical professionals to notice warning signs of eating disorders, so attending regular checkups can allow for early diagnosis and intervention.
