Pucker up! kissing may fight cavities, study suggests

This study looked at whether kissing on the mouth can help neutralize acid in the mouth after drinking sugary or fermented drinks like soda or beer. Acid can weaken tooth enamel and lead to cavities. Researchers gave 33 healthy adults these drinks, then measured their saliva pH every 5 minutes. One group kissed their partner for 40 seconds, while the other did not. The goal was to see if kissing helps the mouth return to a neutral pH faster, potentially protecting teeth.
