A review found that cannabinoids modulate autophagy in oral tissues by inhibiting mTOR and promoting cell recycling, with potential for oral cancer and periodontal disease, but no clinical data exists.

Cannabinoids inhibit PI3K/AKT/mTOR and activate AMPK/Beclin-1 autophagy pathways in oral tissues
What the researchers found
Cannabinoids acting through CB1 and CB2 receptors modulate autophagy by inhibiting PI3K/AKT/mTOR, activating AMPK and Beclin-1, and promoting ROS-induced autophagy. These mechanisms have dual anti-inflammatory and anti-cancer potential in oral tissues. Cannabinoid-induced autophagy may also enhance stem cell survival for dental pulp regeneration.
Why it matters
Oral cancers and periodontal disease have limited treatment options. Understanding how cannabinoids interact with cellular recycling in oral tissues could open new therapeutic approaches, though this remains early-stage.
The numbers in context
Key pathways: PI3K/AKT/mTOR inhibition, AMPK activation, Beclin-1 upregulation. Receptors: CB1 and CB2. Applications: OSCC, periodontitis, gingival inflammation, dental pulp regeneration.
How the study worked
Narrative review of experimental studies on cannabinoid-autophagy interactions in oral tissues, covering oral squamous cell carcinoma, periodontitis, gingival inflammation, and dental pulp regeneration.
What this study cannot tell us
Primarily preclinical data. No clinical trials. Dose-dependent variability and poor oral bioavailability remain challenges.
How to read the evidence
Mechanistic review of preclinical evidence; no clinical data for oral disease applications.
When this study was published
2026 publication
The bigger picture
Autophagy dysregulation drives both cancer and inflammatory disease. If cannabinoid modulation of autophagy can be targeted to oral tissues, it could be a novel treatment strategy.
Questions still open
- Can cannabinoid formulations achieve sufficient oral tissue specificity? How do smoking-related delivery methods affect oral disease risk?
Common questions
Can cannabinoids treat oral cancer?
What is autophagy?
