Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Menthol oil has traditionally been used in oral care, primarily due to its cooling sensation, fresh flavor, and potential antimicrobial properties. It is a common ingredient in many toothpastes and mouthwashes, offering a refreshing taste and helping to mask bad breath. Historically, menthol, derived from mint oils, has been valued for its ability to soothe minor irritation and provide a feeling of cleanliness in the mouth. Some in vitro studies suggest that menthol possesses mild antibacterial activity, which may contribute to oral hygiene; however, these effects are not robustly supported by large clinical trials specific to dental health outcomes such as caries prevention or gum disease treatment. Its main role in dental products is to enhance flavor and the user's sensory experience rather than to directly support tooth health. In summary, while menthol oil's use in the "Teeth body system" is grounded in tradition and some plausible but limited antimicrobial effects, strong scientific evidence for its therapeutic benefit for teeth is lacking.
