Can you transfer cavities by kissing?

My girlfriend and I were discussing cavities, and she told me they can be contagious. I thought they were just from bad brushing. Can you actually transfer cavities to someone else by kissing them?

Yes, actually you can transfer the cavity-causing bacteria like Streptococcus mutans through saliva when kissing. I had to get multiple fillings done because of poor oral hygiene habits in my family. The best way is to ensure both partners do regular brushing, flossing, and scaling at the dentist.

Our elders always told us not to eat from the same plate to avoid spreading sickness, which is very true. Our family dentist also confirmed that sharing saliva can pass cavity bacteria. It is best to maintain good oral hygiene and get regular cleanings done.

Beta, the dirt and bad germs in the mouth can easily pass from one person to another when you share food or kiss. That is why our elders always said to clean the mouth nicely after eating. Just keep your teeth clean and wash your mouth regularly.

I love eating chocolates and desserts late at night, but that also means keeping my dental health in check. Since bacteria can transfer, make sure both of you brush properly after enjoying sweet treats so you don't share unwanted cavities along with love!

Yes, bacteria can definitely spread through saliva. It's a good idea for both people to maintain basic dental hygiene and get regular checkups.

It is true that bacteria can pass, but please don't worry too much about it. As long as you brush twice a day and visit your dentist regularly, you will be absolutely fine.

Saliva sharing does transfer oral bacteria, which can increase the risk of tooth decay if the other person has active cavities. To save time and dental bills, just make sure both of you visit a dentist twice a year and maintain a basic hygiene routine.

Technically, yes, because the oral microbiome is transmissible. If your partner has high levels of decay-causing bacteria, kissing can pass them to you. I track my routine doctor visits and dental checkups on my health app to make sure everything stays in peak condition.
