Kissing: Is it good or bad for your teeth?

Surprisingly kissing is good for your teeth: when you kiss it increases saliva production maintaining a healthy smile.

Saliva is a natural protective system for the teeth; it washes bacteria and food off the tooth surface and neutralizes the effects of acids. It also provides a sufficient supply of calcium and fluoride ions and reduces friction. Saliva also maintains the pH level and mineral balance in the oral cavity, therefore protecting teeth from caries. 

However, as saliva is exchanged during a kiss, so are the bacteria. If one of the kissers has bad teeth and poor oral hygiene, various harmful bacteria may be transmitted to the partner via saliva or blood, which may cause such infections.

It is also believed that periodontal diseases can also be transmitted through saliva, which is why if one family member, or partner is diagnosed with a periodontal disease, you should consult your dentist, too.

However, passionate kisses are good for oral health – saliva contains substances that help fight bacteria, viruses, and fungi and protect tooth enamel.

To make certain that you maintain your oral health it is wise to visit your dentist and hygienist on a regular basis.
