The clinical implications for dentists of patients’ cannabis use
Dental professionals are increasingly likely to encounter patients who disclose cannabis use.
Cannabis is the most commonly used illicit drug in the United Kingdom, with recent public health statistics indicating a steady rise in its recreational use.
Dental professionals are increasingly likely to encounter patients who disclose recreational cannabis use.
In BDJ Team, Manas Dave, Academic Clinical Fellow, and Neil Patel, Senior Lecturer in Oral Surgery, University of Manchester, examine the impact of recreational cannabis on oral and general health and outline appropriate dental management strategies.
Discussion should be framed within a context of patient-centred care, ensuring that the advice is both informative and supportive

They say the aim is to provide practical, evidence-based guidance that enhances patient care and inter-professional collaboration.
“When a patient discloses cannabis use, oral healthcare professionals should adopt a non-judgemental, supportive approach. Clinicians should ask open-ended questions to understand the frequency, duration, and method of use. For instance:
- ‘Can you tell me about your cannabis use and how often you use it?’
- ‘Have you noticed any changes in your oral health, such as dry mouth, toothache or tooth and/or gum sensitivity?’
“These questions provide information for risk/susceptibility assessment but also encourage honest dialogue. It is important to integrate these inquiries into the broader context of a comprehensive medical and social history. A diet diary may also be useful to understand irregular snacking habits.
“Oral healthcare professionals should advise patients on the potential oral health risks associated with cannabis use. Recommendations include:
- Enhanced oral hygiene: emphasise the importance of regular brushing, flossing and the use of fluoride toothpaste to counteract the increased risk of caries and periodontal disease.
- Hydration: encourage patients to maintain adequate and appropriate hydration (with plain water) to mitigate xerostomia.
- Regular dental visits: reduce recall intervals for dental consultations for active surveillance of any emerging issues related to cannabis use.
- Lifestyle modification: provide or signpost support for reducing or ceasing cannabis use, where appropriate.
“The discussion should be framed within a context of patient-centred care, ensuring that the advice is both informative and supportive.”
