Essential oils and Mouth Hygiene
Essential oils have been utilised in complementary medicines like Ayurveda for bacterial and fungal infections for many years. In this study Chaudari et al studied the antibacterial activity of nine commercially available essential oils against Streptococcus mutans in vitro and evaluated comparatively the antibacterial activity between each material.
Wintergreen oil, lime oil, cinnamon oil, spearmint oil, peppermint oil, lemongrass oil, cedarwood oil, clove oil and eucalyptus oil were selected for the study.
They conclude that Cinnamon oil, Lemongrass oil, cedarwood oil, clove oil and eucalyptus oil exhibit antibacterial property against S. mutans. Their use could be a viable alternative to other antibacterial agents in the control of both bacteria and yeasts responsible for oral infections.
