Essential oil mouthwashes: a key component in oral health management.
This Supplement provides clear evidence that essential oil (EO) mouthwashes can be a beneficial, safe component of daily oral health routines. However, despite the wealth of supporting evidence, several issues are worthy of discussion. Patient compliance is a clear issue with oral home-care routines, and the emphasis is on dental professionals to communicate the importance of adherence. The reasons for each step of the oral-care routine (i.e. brushing, flossing, rinsing) should be clearly explained, and if required, additional motivation should be provided. Most mouthwashes contain denatured alcohol as a delivery vehicle, and some concern has been raised about the association of alcohol with oral cancer. However, a review by the Food and Drug Administration and American Dental Association found that the supporting evidence to date is inconsistent and contradictory. Some mouthwashes have a pH below 5.5, and some researchers believe that this can lead to tooth erosion. Studies have shown that although the pH of an EO mouthwash is below 5.5, salivary pH remains above 5.5 following rinsing and for 15 min postrinse.
