Medications play a critical role in treating a plethora of health conditions, but they aren't without their drawbacks. One significant oral health issue influenced by medication is bruxism -- a condition characterized by involuntary teeth grinding and clenching. This condition can result in enamel erosion, increased tooth sensitivity, and a higher risk of cavities. In some instances, it may even lead to fractures, which may require tooth extraction.
Dentists must be familiar with this medication side effect and able to counsel patients about it. Luckily, nightguards are a simple, in-office solution that most dentists can easily fabricate for patients as a preventive measure. Looking out for medications that may increase a patient's risk of bruxism is one easy way to boost practice revenue while improving patients' oral health.

Many don't realize that common medications can trigger bruxism. Research indicates a link between bruxism and alterations in neurotransmitters like norepinephrine, dopamine, and serotonin.
Although stress and neurological conditions like Parkinson's disease are well-known triggers, several medications can also heighten a person's risk. These medications include the following:
1. ADHD medications: Stimulants such as Adderall (amphetamine and dextroamphetamine), Vyvanse (lisdexamfetamine), and Ritalin (methylphenidate) are prescribed for attention deficit hyperactivity disorder (ADHD) and influence neurotransmitter levels, potentially leading to bruxism. This is particularly important to know, considering that prescriptions for ADHD medications surged during the pandemic.
2. Antidepressants: Certain antidepressants are also linked to bruxism. Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac) primarily affect serotonin levels, while norepinephrine and dopamine reuptake antagonists (NDRAs) such as bupropion (Wellbutrin) increase the availability of norepinephrine and dopamine. Antipsychotics like risperidone (Risperdal), which target both dopamine and serotonin receptors, can also influence this condition.
3. Parkinson's medications: Medications for neurological conditions like Parkinson's may exacerbate bruxism due to their effect on dopamine levels. For example, levodopa (found in levodopa/carbidopa) acts as a dopamine precursor, enhancing dopaminergic activity.
By understanding the interplay between medications and oral health, dental care professionals can enhance their approach to holistic patient care. Figuring it out on your own isn't easy, though, which is why tools like the Digital Drug Handbook exist. It dissects what your patients are taking into dentistry-specific bullet points that match dental workflows.
