Dental caries counts among the most widespread chronic diseases, characterized by localized destruction of dental hard tissues1. Dental plaque is a microbial biofilm that forms on the tooth surface and contains a complex structure of microorganisms. The metabolic activity of the bacteria in this biofilm is directly linked with the dental caries process.
Tea tree essential oil is an essential oil extracted from steaming the leaves of Melaleuca alternifolia. It is generally accepted that essential oils possess bioactive properties, including antimicrobial properties. Therapeutic properties of the Tea tree oil, including antimicrobial activity, were reported in the early 20th century. Several studies indicated that Tea tree oil is very effective in vitro against a broad range of bacteria, including oral bacteria.
Tea tree essential oil was evaluated against oral bacteria associated with tooth cavities (dental caries)—Streptococcus mutans and S. sobrinus—demonstrating strong antibacterial efficacy by inhibiting bacterial growth and biofilm formation, while preventing bacterial adhesion to human teeth. After the success in human teeth previously removed, the researchers further evaluated the activity of a 25% tea tree essential oils solution in distilled water on rat’s teeth. They found that the oil reduced the depth and number of cavities.
To make this natural rinse, combine a few drops of tea tree oil with a cup of warm water, stir to combine, and swish!
Tip: This recipe can also be made with Lemongrass oil, if you prefer.
