Reviewed by Dr. Paul Rubin
Reading time: three minutes
If your child takes medication for ADHD, you may already be familiar with the changes in focus, behavior, and appetite these medications can bring. But what many parents do not realize is that ADHD medication side effects can also show up in your child’s mouth.
As a pediatric dental office that frequently works with children who are neurodivergent, we can help you understand what to look out for and how to protect your child’s smile.
Key Takeaway
ADHD medications can cause side effects like dry mouth, inflammation, and teeth grinding that impact oral health. Recognizing these issues early allows parents and pediatric dentists to work together to protect a child’s teeth and gums.

Common Dental Side Effects of ADHD Medication
All types of ADHD medications, including both stimulants and non-stimulants, can affect oral health in different ways. Below are some of the most common issues we see in children who take these medications.
1. Dry Mouth (Xerostomia)
Dry mouth is one of the most common ADHD medication side effects. It can reduce the natural flow of saliva, which normally helps wash away food and neutralize acids. Less saliva means a higher risk for:
- Tooth decay
- Gum disease
- Bad breath
If your child is taking ADHD medication, especially a stimulant, it is a good idea to increase water intake and schedule more frequent dental cleanings.
2. Inflammation
Some children experience inflammation of the soft tissues in the mouth, including the tongue, gums, salivary glands, or even the sinuses. This can cause soreness or discomfort and may affect how your child eats or talks.
3. Difficulty Swallowing
ADHD medications can sometimes cause swallowing issues, which may lead to problems with eating, drinking, or even taking other medications. These challenges may also contribute to poor oral hygiene if brushing becomes uncomfortable.
4. Teeth Grinding (Bruxism)
Clenching or grinding the teeth, especially at night, is another possible side effect. Over time, this can wear down tooth enamel and cause jaw pain, sensitivity, or cracked teeth.
If you suspect your child is grinding their teeth, we can check for signs of wear and recommend a nightguard if needed.
5. Appetite Suppression and Late-Night Cravings
ADHD medications often suppress appetite during the day. Once the medication wears off at night, some children experience a sudden, intense hunger and may binge eat. This can sometimes go unnoticed, especially if it happens in the middle of the night.
This type of uncontrolled nighttime grazing increases the risk of tooth decay, particularly if sugary or starchy foods are involved and brushing does not follow.
Keeping an eye on late-night eating habits and encouraging a consistent oral hygiene routine before bed can help protect your child’s teeth.

What You Can Do at Home
Here are a few ways to reduce the risk of oral health problems linked to ADHD medication side effects:
- Encourage your child to sip water throughout the day
- Avoid sugary or acidic snacks, especially when saliva is low
- Keep up with twice-daily brushing and flossing
- Use fluoride toothpaste and consider an additional fluoride rinse
- Talk to us about prescription mouthwashes or saliva substitutes if dryness is severe
Every child reacts differently to medication. If your child has started a new ADHD medication and you have noticed increased cavities, gum sensitivity, or mouth discomfort, please let us know. We can adjust their dental care plan to help manage these side effects and protect their long-term oral health.
