Eating disorders, such as anorexia nervosa, bulimia nervosa, and binge eating disorder, not only affect a person’s overall health but can also have severe consequences on their dental health.

The relationship between eating disorders and poor oral health is well-documented, with numerous warning signs that dental professionals can identify. In this article, we will explore the dental warning signs associated with eating disorders, their implications, and the importance of early detection and intervention.

1. Erosion of Tooth Enamel

One of the key dental warning signs of eating disorders is the erosion of tooth enamel.

Frequent self-induced vomiting or excessive consumption of highly acidic and sugary foods and drinks can lead to the erosion of the protective layer of enamel on the teeth. As a result, the teeth become susceptible to cavities, sensitivity, and discoloration.

2. Teeth Sensitivity

Individuals with eating disorders may experience increased tooth sensitivity. Tooth sensitivity can occur when the enamel wears away, exposing the underlying dentin.

It can lead to discomfort or pain while consuming hot, cold, or sweet foods and beverages.

3. Gingivitis and Gum Disease

Poor nutrition, which is often associated with eating disorders, weakens the immune system, making it easier for bacterial infections to occur.

Gingivitis, characterized by red, swollen, and bleeding gums, is a common oral health issue among individuals with eating disorders. If left untreated, it can progress to more severe gum disease, including periodontitis.

4. Dry Mouth

Eating disorders can lead to reduced saliva production, resulting in dry mouth (xerostomia). Saliva plays a crucial role in maintaining oral health as it helps wash away food particles, neutralize acid, and prevent tooth decay.

Dry mouth can increase the risk of cavities, bad breath, and oral infections.

5. Enlarged Salivary Glands

The repeated intake of large amounts of food or self-induced vomiting can cause the salivary glands to enlarge. This can be visually identified as swollen or puffy cheeks, especially in the parotid gland area.

Enlarged salivary glands can be painful and contribute to discomfort while eating or speaking.

6. Mouth Sores and Cuts

Eating disorders may lead to frequent self-induced vomiting, which subjects the oral tissues to stomach acid exposure. This can cause mouth sores and cuts, particularly on the palate and the back of the throat.

These sores can be painful and increase the risk of infections.

7. Buckled Teeth

Malnutrition and vitamin deficiencies associated with eating disorders can weaken the bone structure, including the jawbone. This can result in changes to the alignment of the teeth, leading to bucked or crooked teeth.

8. Halitosis

Chronic bad breath (halitosis) is another warning sign of eating disorders. Improper nutrition and dry mouth contribute to the growth of bacteria in the mouth, leading to foul-smelling breath.

Additionally, the presence of untreated cavities or mouth sores can worsen halitosis.

9. Thinning or Bleeding Gums

Deficiencies in vitamins and minerals due to poor nutrition can weaken the gums, making them more prone to bleeding. In severe cases, the gums may begin to recede, giving the appearance of longer teeth.

Proper nutrition is essential to maintain healthy gums and prevent gum-related complications.

10. Tooth Decay

The combination of poor nutrition, frequent vomiting, and increased intake of sugary and acidic foods can lead to rampant tooth decay. Tooth decay occurs when acids produced by bacteria in the mouth erode tooth enamel.

If left untreated, decay can progress to severe cavities, tooth abscesses, and even tooth loss.

It is crucial for dental professionals to be aware of these dental warning signs to identify potential underlying eating disorders in patients.

Early detection allows for timely intervention and multidisciplinary treatment, involving dental professionals, physicians, and mental health specialists.

Remember, if you suspect someone is suffering from an eating disorder based on their dental signs, it is important to approach the topic with sensitivity and compassion, encouraging them to seek professional help.

Together, we can help individuals struggling with eating disorders regain their oral health and overall well-being.
