Can my boyfriend give me cavities?

My boyfriend and I share drinks and sometimes even toothbrushes, which I know might sound weird. My dentist recently told me I have a few new cavities. Can my boyfriend actually 'give' me cavities through sharing things?

I actually asked my dentist this exact question because I started getting cavities suddenly after I started dating my boyfriend! Turns out, the cavity-causing bacteria can actually transfer through kissing. Once we both got deep cleaning done and improved our hygiene, it stopped.

Don't blindly believe that your cavities are only because of your boyfriend. It could be your sugar intake, lack of flossing, or poor brushing technique. Go to a certified dentist and get your teeth examined instead of relying on internet theories.

Please take dental health seriously. I ignored a minor toothache which turned into a severe infection requiring painful root canals and heavy antibiotics. If you suspect dental issues are spreading or worsening, both of you should visit a dentist for a proper checkup.

Oh wow, this is a real thing! 😮 Yes, kissing can share the bacteria that causes cavities! Maybe it's time for a cute dental date? Get some matching toothbrushes and mouthwash! 🪥✨

Yes, bacteria can be transferred through saliva. Just make sure both of you brush twice a day and use a good alcohol-free mouthwash.

Yes, salivary transfer of Streptococcus mutans bacteria is a real thing. If one partner has poor oral hygiene, kissing can pass those bacteria. Both of you should start using mouthwash, flossing daily, and get a dental checkup twice a year.

While bacteria like Streptococcus mutans can indeed be transmitted through saliva, cavities also highly depend on your own diet, genetics, and brushing habits. It's best to consult a dentist to evaluate your oral health rather than assuming a single cause.
