Is Kissing Dangerous to Your Dental Health? 

Oddly enough, yes. Studies have shown that bacteria that cause tooth decay can be transmitted via an open mouth kiss. Within one kiss, you can share over 500 types of disease-causing germs and viruses. Cavities can become contagious. However, it is only an issue if the person you are kissing has several dental cavities yearly, which can signify that they may have an above-average bacteria count. With that said, there is no reason to stop kissing. Before kissing, try brushing your teeth or rinsing your mouth with mouthwash. If not convenient, chew on sugar-free gum or drink a glass of water. If you feel your partner may be an issue, you can always brush and floss your teeth afterward. In short, kissing is acceptable but know who you kiss and stay healthy.
