Pine bark extract, particularly from the French maritime pine (Pinus pinaster), is rich in proanthocyanidins and other polyphenols. There is some scientific research investigating its effects on oral health, including gum (periodontal) health. A few clinical studies have examined the use of standardized pine bark extract (often branded as Pycnogenol) in reducing symptoms associated with gingivitis and periodontitis. These studies suggest that pine bark extract may help lower gingival bleeding, reduce plaque formation, and improve some markers of periodontal inflammation, likely due to its antioxidant and anti-inflammatory properties.

However, the evidence base is limited: most trials are small, short-term, and sometimes lack rigorous controls. There is not enough high-quality research to definitively confirm its efficacy for gum health or to recommend it as a primary therapy for gum disease. Its use in this context is not rooted in long-standing tradition but rather in recent nutritional and pharmacological research. While laboratory and animal studies also show promise for pine bark extract’s role in reducing oral bacteria and modulating inflammation, these findings have not been robustly translated into clinical practice.

In summary, there is preliminary scientific support for pine bark extract’s benefits for gum health, but the overall strength of the evidence is modest at present.
