Essential oils have been used for oral health for centuries, and clinical studies are finally proving their safety and efficacy. In addition to therapeutic herbs and other healing agents, many essential oils show a very beneficial effect upon teeth and gums as well.
According to a 2014 study published in the Journal of International Oral Health:
Essential oil rinses are found to be equally effective in inhibiting plaque. A study carried out by Pizzo et al. on plaque inhibitory effect of amine fluoride/stannous fluoride and essential oils showed no significant difference in efficacy of both. As chlorhexidine causes staining of teeth on long term use, essential oils can be used as an alternative to chlorhexidine rinse. Essential oils have shown to possess antimicrobial activity against subgingival periopathogens too.
Tea tree oil
Human clinical trials have confirmed its antibacterial, antifungal, antiviral and antiprotozoal activity showing that tea tree oil effectively reduces bacterial load and yeast and fungal infections, as well as treats viral infections and relieves the symptoms of gingivitis and those of denture stomatitis.
Moreover, tea tree oil is effective against bad breath. Scientists evaluated and reported that tea tree oil reduces the bacterial colonies that cause halitosis, making it beneficial for oral health.
The major compound of clove oil known as eugenol has been widely used for its anesthetic and analgesic action in dentistry. Eugenol possesses significant antioxidant and anti-inflammatory properties, in addition to having analgesic and local anesthetic activity.
Additionally, a recent study that evaluated clove’s ability to slow tooth decalcification (dental erosion). Not only did clove oil lead the pack by “significantly” decreasing decalcification, it was observed that it actually remineralized teeth.
