Copaiba Oil for Gingivitis: Scientific Evidence Overview

Copaiba oil, derived from the resin of the Copaifera tree native to South America, has been traditionally used for various inflammatory conditions. More recently, its potential for supporting oral health—specifically in the management of gingivitis—has attracted scientific attention. Several in vitro and in vivo studies have investigated copaiba oil's antimicrobial and anti-inflammatory properties relevant to oral pathogens and gum inflammation.

A small number of clinical trials and laboratory studies have indicated that copaiba oil exhibits inhibitory effects on the growth of bacteria commonly associated with gingivitis, such as Streptococcus mutans and Porphyromonas gingivalis. Additionally, its anti-inflammatory activity may help reduce gum swelling and redness. For example, a 2017 randomized controlled trial reported that a copaiba-based mouthwash reduced gingival inflammation and bleeding, with outcomes comparable to chlorhexidine, although larger and more rigorous studies are needed.

Despite these promising findings, the evidence is still limited in scope and quality. Most studies are preliminary, have small sample sizes, or lack long-term follow-up. As such, while scientific interest and early data exist, copaiba oil cannot yet be recommended as a first-line treatment for gingivitis, but it is being explored for complementary use.
