Does ADHD medication cause teeth grinding?

Attention deficit hyperactivity disorder (ADHD) medication may be one factor in teeth grinding, but it is not always the cause. Certain medicines used to treat ADHD may increase the chances of bruxism. Bruxism is the clinical word for teeth grinding or jaw clenching.  

What you will learn in this article:  

• Certain medicines used to treat ADHD may increase the chances of teeth grinding. 

• Grinding can happen during the day or at night, often without you noticing. 

• Severe bruxism can damage teeth and cause jaw or head pain. 

• Talking with your prescriber and Aspen Dental provider is a good first step. 

If you take ADHD medication and have noticed jaw soreness, headaches or signs of grinding, schedule an appointment with an Aspen Dental provider. They can check your teeth for wear and help you protect them while you talk with your prescriber about whether the medication may be contributing.  

What is bruxism? 

Bruxism means grinding, clenching or gnashing your teeth. It can happen while you sleep. It can also happen during the day. You may not know you're doing it at all. 

Your jaw muscles are very strong. Over time, grinding puts a lot of force on your teeth. That force can wear them down or crack them. 

How does ADHD medication fit in? 

According to the National Institute of Dental and Craniofacial Research (NIDCR), certain medicines used to treat ADHD may increase the chances of bruxism. NIDCR also lists stress, mood, genes, caffeine, alcohol and smoking as factors that may play a role.¹ That means medication can be one factor, but it does not prove your medicine is the cause. 

Research also shows that the connection is not simple. A 2026 study in European Oral Research looked at children and teens with ADHD who took methylphenidate, atomoxetine or no medication. Bruxism severity did not differ significantly between the medication groups. Instead, more severe ADHD symptoms were linked with more severe bruxism.² The study looked at children and teens at one point in time, so it cannot prove what caused the grinding or tell us exactly what happens in adults. 

If grinding or clenching started after you began or changed a medicine, tell your prescriber and dental provider. 

What can happen if it goes untreated? 

According to the NIDCR, severe bruxism can lead to damaged teeth, jaw pain or tiredness and headaches. Teeth may become flattened, chipped, cracked or loose. Worn enamel can expose the inner layers of a tooth and cause sensitivity.¹

Some people grind during sleep or do not know they are doing it. Regular dental exams give your dental provider a chance to look for signs of bruxism. 

What can you do to manage your grinding? 

Treatment depends on what may be contributing to the grinding. The Mayo Clinic notes that if bruxism is a medicine side effect, a healthcare professional may change the dose or suggest a different medicine. It also says mouth guards can help prevent tooth damage from grinding and clenching.³ 

Talk to your prescriber 

Tell your prescriber if jaw tension, teeth grinding or a sore jaw started after you began or changed your ADHD medicine. They can review whether the medication may be contributing and whether a change is appropriate. Do not stop or change your medication on your own. 

See your dental provider 

Tell your dental provider about the grinding and any medicines you take. They can check your teeth and jaw for signs of bruxism. A mouth guard may help protect your teeth, but it may not stop the grinding itself. Your dental provider can tell you whether one is right for you. 

Notice the signs 

Signs to watch for include: 

• A sore, tight or tired jaw 

• Headaches or facial pain 

• Tooth pain or sensitivity 

• Visible tooth damage, such as a chipped or cracked tooth 

• A partner telling you that you grind during sleep 
  

Does ADHD medication cause teeth grinding? FAQs  

Still have questions about ADHD medication and teeth grinding? These answers cover a few common concerns. 

Does everyone who takes ADHD medication grind their teeth? 

No. Certain ADHD medicines may increase the chances of bruxism, but that does not mean everyone who takes them will grind or clench their teeth. 

Will stopping my medication fix the grinding? 

That is a question for your prescriber, not a decision to make on your own. Medication changes need medical guidance. Your dental provider can help protect your teeth in the meantime. 

Can stress management help reduce grinding even if medication is a factor? 

Possibly. The NIDCR lists stress as one of several factors that may contribute to bruxism, alongside medication, mood, genes, caffeine, alcohol and smoking. If multiple factors are present at the same time, addressing more than one of them may help. Talk with your prescriber and dental provider about what combination of approaches makes sense for your situation. 

Is jaw pain from bruxism dangerous? 

Jaw pain or tiredness can happen with severe bruxism. But jaw pain can have other causes too. If it keeps happening or affects your daily life, tell your dental provider and your prescriber.
