Kissing as a Protective Factor Against Acidic pH in Saliva

The pH of saliva can be acidic or alkaline; When it is acidic, the tooth enamel is demineralized, that is, weakened. Additionally, bacteria in the mouth can increase and cause infections such as cavities. This occurs when we consume sugary or fermented drinks, such as soda or beer. The intention of the research team is to give some of these drinks to the study participants and verify the decrease in salivary pH. Next, a group of people will be asked to kiss their partner on the mouth, and then the pH will be measured again to see if it increases, that is, if it stops being acidic faster than in the group that did not kiss. The aim is to demonstrate that kissing on the mouth between two people can protect teeth from cavities by rapidly increasing the pH of saliva after it has decreased to become acidic.
