Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Tannin is a polyphenolic compound found in various plants, known for its astringent, anti-inflammatory, and antimicrobial properties. In the context of oral surgery, tannin-containing preparations (e.g., from plants like witch hazel or oak bark) have been traditionally used to control minor bleeding and promote mucosal healing. Scientifically, there is some evidence supporting these uses: tannins can precipitate proteins, leading to the formation of a protective layer over oral wounds, which may help reduce bleeding and protect against infection.

Several in vitro and animal studies have demonstrated that tannins exhibit antimicrobial activity against oral pathogens. Their astringent effect can also reduce inflammation and edema, potentially supporting wound healing. However, clinical studies in humans specific to post-oral surgery applications are limited, and the available evidence is not robust. Reviews and small clinical trials suggest that mouthwashes or gels containing tannins may aid in the management of minor oral mucosal lesions and gingivitis, which are related to oral surgery recovery, but direct high-quality trials focused on oral surgery outcomes are lacking.

Therefore, while there is a plausible scientific basis and some preliminary evidence for the use of tannins in supporting oral surgery (mainly for hemostasis and antimicrobial effects), the overall quality of evidence is modest, warranting a rating of 2 on a 0-5 scale.
