Why It’s Important to See Your Dentist if You Have an Eating Disorder
Caring for Your Whole Health — Mouth Included
When we think about eating disorders, we often focus on nutrition, mental health, and body image. But there’s one part of the body that often gets overlooked — even though it’s affected early and often:
Your mouth.
More specifically, your teeth, gums, enamel, and jaw.
Whether you're struggling with anorexia, bulimia, ARFID, or another form of disordered eating, your oral health is part of your overall health — and your dentist can play an important role in early detection and long-term healing.
How Eating Disorders Affect Oral Health
Different types of eating disorders can impact the mouth in different ways:
Bulimia (purging behaviors):
Frequent vomiting exposes the teeth to stomach acid, which can lead to:
Tooth enamel erosion
Increased sensitivity
Tooth decay and discoloration
Mouth sores, cracked lips, and dry mouth
Swollen salivary glands (especially near the jaw)
Anorexia or Severe Restriction:
When the body is undernourished, it lacks the building blocks to maintain healthy gums and teeth. Common issues include:
Dry mouth (from dehydration)
Gum disease
Tooth loss or thinning
Mouth pain or sores
Delayed healing from dental work
ARFID (Avoidant/Restrictive Food Intake Disorder):
Teens and children with ARFID may avoid nutrient-dense foods or have a very limited diet. Over time, this can cause:
Nutritional deficiencies (low calcium, vitamin D, etc.)
Increased cavity risk
Delayed jaw development or tooth eruption
Sensory issues around brushing or dental visits
Dentists Can Help Spot Early Warning Signs
In many cases, a dentist is the first healthcare provider to notice signs of an eating disorder — especially with purging or severe restriction.
A caring, non-judgmental dentist may notice:
Enamel loss on the inside of the teeth
Increased decay or gum recession
Unexplained mouth sores or inflammation
If they gently raise concerns, it’s a good idea to listen — they’re trying to help protect your long-term health, not shame you.
Why It’s Important to Tell Your Dentist (If You Feel Safe Doing So)
It may feel awkward or scary to talk about an eating disorder with your dentist. But sharing that you’re in treatment — or struggling — allows them to tailor your care to protect your mouth, such as:
Using gentler cleanings if your teeth are sensitive
Recommending products that strengthen enamel
Avoiding unnecessary whitening treatments or procedures
Providing saliva substitutes or fluoride trays
Educating you on safe oral care after purging (hint: don’t brush right after — rinse with baking soda or water first!)
Your dentist is part of your care team. They want to help — not judge.
How to Protect Your Teeth During Recovery
Here are a few tips to care for your mouth while healing:
✅ Don’t brush immediately after vomiting.
Rinse with water or baking soda solution to neutralize acid, then wait 30 minutes before brushing.
✅ Use a soft-bristled toothbrush and gentle toothpaste.
Sensitive teeth need extra TLC.
✅ Stay hydrated.
Dry mouth increases cavity risk.
✅ Ask about fluoride rinses or prescription-strength toothpaste.
✅ Keep up with regular dental checkups.
Even if you're nervous, staying ahead of damage is easier than fixing it later.
Final Thoughts
Eating disorders affect the whole body — including the parts you don’t always see. But with the right support, your body (and mouth!) can heal.
Seeing your dentist regularly — and looping them into your treatment journey when you feel safe — is one more way to care for yourself during recovery.
