Dentists Reports Patients Coming to Appointments High on Marijuana What recommendations do you have for future research as a result of this study?

Response: The American Dental Association has been calling for more research around patient use of cannabis since 2021 when it passed a resolution to encourage the development of best practices for the management of patients and their caregivers. Increased external research in this area could support the development of useful resources for dentists and their teams, including evidence-based guidance on the oral effects of cannabis. Is there anything else you would like to add?

Response:  Marijuana use can affect the mouth in a number of ways including exacerbating gum disease, increasing risk of cavities, dry mouth, and head and neck cancers. Good daily oral hygiene is essential for all, including: brushing twice a day with fluoride toothpaste, cleaning between teeth daily, visiting the dentist regularly and making healthy snack choices. People who are regular users of marijuana should consult their dentist for individualized recommendations based on their current oral health conditions.
