Eating disorders such as bulimia nervosa and anorexia nervosa are complex mental health conditions affecting millions worldwide.
While these disorders’ physical and psychological consequences are widely recognized, their detrimental impact on oral health is often overlooked.
How do eating disorders such as anorexia affect oral health?
Anorexia is a severe eating disorder characterized by restrictive eating patterns and an intense fear of gaining weight. While the physical and psychological consequences of anorexia are well-known, its effects on oral health are often overlooked.
This article aims to provide a detailed overview of how anorexia can impact oral health based on clinical references and research studies.
Tooth Erosion and Enamel Damage
A prominent consequence of anorexia is the lack of proper nutrition, including calcium and other essential minerals. This deficiency weakens tooth enamel, making teeth more susceptible to erosion.
Frequent vomiting, sometimes induced to control weight, exposes teeth to stomach acids, leading to enamel erosion and increased tooth sensitivity.
Dry Mouth (Xerostomia):
Dehydration from restricted fluid intake can reduce saliva production, causing dry mouth.
Saliva is crucial in neutralizing acids, remineralizing teeth, and maintaining oral health.
Insufficient saliva flow increases the risk of tooth decay and oral infections.
Gum Disease (Gingivitis and Periodontitis)
Anorexia compromises the immune system, making individuals more susceptible to gum disease.
Poor nutrition and vitamin deficiencies associated with anorexia can lead to gum inflammation, bleeding, and potential tooth loss.
Dental Cavities
Irregular eating patterns, reduced food intake, and a lack of proper oral hygiene can increase the risk of dental cavities.
The mouth becomes more acidic due to reduced saliva flow, creating an environment conducive to tooth decay.
Oral Soft Tissue Problems
Nutritional deficiencies associated with anorexia can result in oral soft tissue problems, such as dry and cracked lips, oral sores, and delayed wound healing.
Anorexia nervosa can have severe consequences for oral health, including tooth erosion, enamel damage, dry mouth, gum disease, dental cavities, and oral soft tissue problems.
It is crucial to recognize these risks and seek appropriate dental care as part of the comprehensive treatment approach for anorexia.
What does Bulimia do to your teeth, and does repeated vomiting cause dental problems?
Bulimia is an eating disorder characterized by recurrent episodes of binge eating followed by compensatory behaviours such as self-induced vomiting, excessive exercise, or the misuse of laxatives.
Dental Erosion Damaging Tooth Enamel
Frequent vomiting exposes teeth to stomach acid, leading to enamel erosion and weakening of tooth structure.
Enamel erosion can result in tooth sensitivity, increased susceptibility to cavities, and aesthetic changes, such as tooth discolouration and changes in tooth shape and size.
Tooth Cavities
Binge eating episodes often involve consuming sugary and acidic foods, which can promote tooth decay.
The combination of frequent vomiting and poor oral hygiene practices exacerbates the risk of dental cavities.
Sensitive Teeth and Tooth Sensitivity
Enamel erosion from recurrent vomiting can lead to tooth sensitivity, resulting in discomfort or pain when consuming hot, cold, sweet, or acidic foods and beverages.
Worn enamel exposes dentin, a sensitive layer of the tooth, which can lead to heightened sensitivity.
Swollen Salivary Glands
Bulimia-related behaviours, such as self-induced vomiting, can cause swelling and inflammation of the salivary glands, particularly the parotid glands.
Swollen salivary glands can be painful and contribute to dry mouth, difficulty swallowing, and an increased risk of oral infections.
Oral Trauma
Self-induced vomiting can cause trauma to the mouth’s soft tissues, including the palate, causing irritation, scratches, and potential bleeding.
Repeated trauma from the fingers or objects used during purging can lead to chronic damage to the oral tissues.
Bulimia nervosa can have severe consequences for teeth and oral health, including tooth erosion, dental cavities, tooth sensitivity, swollen salivary glands, and oral trauma.
Recognizing and addressing these risks is crucial for individuals affected by bulimia.
