Cannabis Use and Dental Hygiene Appointments

Cannabis use has many side effects that vary based on the person and potency. These have implications for both oral health and professional dental hygiene care. In some cases, dental hygiene appointments may need to be rescheduled to minimize risk. Consider the following side effects:

Fast heart rate and anxiety

Cannabis increases the heart rate and heightens anxiety. These side effects may worsen or last longer with anesthetics used for dental hygiene treatment.

Cannabis use before a dental hygiene appointment may impair judgement and the capacity to provide consent to treatment. 

Confusion and lack of focus

Interaction with medications

Cannabis may alter the effectiveness of prescribed medications. 

Dry mouth and the munchies

Cannabis reduces saliva, leading to dry mouth. It also stimulates

food cravings, which increase the amount of time your teeth are exposed to sugars. As a result, cannabis users have a higher risk of cavities, gum disease, and oral infections. 

Increased bleeding

Cannabis may increase bleeding and complicate dental hygiene care. Healing may also be affected. 

Have a conversation!

Cannabis use is an important part of the health record review.
