Scientists Report on the Protective Properties of Black Tea for Teeth 0 7

During the study, specialists examined the effect of theaflavins on the bacterium Streptococcus mutans, considered the main causative agent of caries, as well as on the enzyme gelatinase B, which is involved in the breakdown of collagen and the weakening of dentin. It was found that they destroy bacterial films on the surface of teeth and suppress the activity of the enzyme.

The mechanism of action involves the direct binding of theaflavin molecules to gelatinase B, leading to a change in its shape and a reduction in functional activity. The extent of the protective effect depended on the chemical structure of theaflavins: the more complex their structure, the stronger the effect.

The authors of the study note that theaflavins should not be considered a cure for caries. However, they may serve as a promising basis for the development of natural preventive agents, including toothpastes, mouthwashes, and other oral care products.
