Scientists have just made a groundbreaking discovery that could revolutionize the way we look at oral hygiene. In a recent study, they found that the composition of the oral barrier is similar to that of ceramides, a type of lipid-like molecule found in the skin.

This could lead to better oral health and fewer cavities, as well as a decrease in other oral health problems.
