A brand new examine suggests tea tree oil (TTO) may assist sufferers at excessive danger of dental caries by inhibiting the expansion of key oral micro organism and stopping biofilm formation.
Revealed in Scientific Studies on Aug. 29, the analysis highlights TTO as a “potent antimicrobial agent in opposition to cariogenic micro organism,” doubtlessly providing a pure different or complement to traditional preventive methods.
Dental caries stay a significant oral well being concern, particularly for sufferers with brushing difficulties, low saliva ranges, or excessive bacterial plaque adhesion. Whereas mechanical and chemical preventive methods exist, conventional brokers equivalent to chlorhexidine may cause tooth staining, toxicity, and xerostomia.
The examine, led by researchers on the College of Saskatchewan, evaluated TTO in opposition to Streptococcus mutans and Streptococcus sobrinus, two main micro organism linked to caries improvement.
Researchers discovered {that a} 12.5 per cent focus of TTO:
- Utterly inhibited bacterial development in vitro
- Prevented biofilm formation on tooth surfaces
- Blocked bacterial adhesion on human tooth

Technique: In vivo testing in rat mannequin
In vivo testing in a rat mannequin confirmed that TTO decreased each the quantity and depth of carious lesions. Rats handled with TTO developed 13 lesions on common, in comparison with 19 within the untreated group, with a big discount in lesion space (p = 0.003). Importantly, TTO didn’t have an effect on reparative dentin formation, suggesting its impact is primarily antimicrobial.
“On this examine, we assessed the antibacterial properties of TTO and demonstrated that it inhibited the planktonic development of S. mutans and S. sobrinus, and, within the course of, TTO inhibited the micro organism’s means to type biofilm,” the authors wrote.
Earlier research have additionally recommended TTO-based mouthwashes might restrict plaque accumulation with fewer unwanted side effects than chlorhexidine.

Additional analysis wanted
The findings underscore a rising curiosity in pure merchandise for oral well being, particularly for high-risk sufferers. Researchers notice that additional medical research are wanted to verify TTO’s preventive advantages in broader affected person populations.
“Future research ought to embrace a wider vary of oral micro organism and bigger pattern sizes to raised mirror medical circumstances and additional validate the efficacy of TTO,” the researchers wrote.
