Can you get cavities from kissing someone with cavities?

My boyfriend has quite a few cavities, and we kiss regularly. I'm a bit worried about my own dental health. Is it possible to get cavities from kissing someone who already has them?

Yes, you can actually transfer cavity-causing bacteria like Streptococcus mutans through kissing. It is a transmissible condition.

Yes, you can. I remember my dentist telling me that we shouldn't share spoons with our kids because the cavity-causing bacteria can transfer. The same logic applies to couples, so it's best to gently encourage your partner to get their fillings done.

Just like keeping our bodies fit with regular jogs and exercise, oral fitness is also about consistency. While bacteria can spread through saliva, maintaining a clean mouth and healthy lifestyle helps fight it off. Just keep up with your oral hygiene routines!

Oh god, so now we have to check our partner's teeth before sharing a sweet dessert? It is true that bacteria can travel, but honestly, eating too much sugary food without brushing is still a much bigger threat to your teeth!

Now you have a solid medical excuse to tell your partner to brush their teeth before bed! Yes, the bugs can hop over, but don't panic, they won't build a colony in your mouth if you floss regularly.

Haan yaar, germs toh share hote hi hain na jab kiss karte hain. But iska matlab yeh nahi ki aapko pakka cavity ho jayegi. Bas apna oral hygiene tight rakho aur partner ko bolo dentist ke paas chakkar laga aaye.

Yes, the bacteria can travel, but don't worry too much! Just keep up with your flossing and maybe share a nice mouthwash together before bed. Keep smiling! 😁

I freaked out when I read this online because my wife had two cavities. But my dentist reassured me that my enamel is strong and normal kissing won't suddenly rot my teeth overnight. Just keep brushing twice and you will be fine.

I completely understand why this makes you anxious, I felt the same when I heard about bacteria transferring. But please don't stress too much. As long as you have good dental habits and regular checkups, your mouth can handle it.

I actually got two cavities right after my partner developed some deep dental issues. My dentist confirmed the bacterial transfer was the likely cause. Once my partner got those teeth filled, my oral health went back to being perfectly fine.

I totally get it, it can feel a bit uncomfortable to think about sharing dental germs. But don't let it ruin your moments. Just encourage your partner to get their dental checkup done, and you do yours too.

I love tracking all my health data and yes, the science says Streptococcus mutans is transmissible. If your partner has active decay, the bacterial load in their saliva is high. Just maintain a strict brushing and flossing routine to keep your defenses up.

Let's be direct: yes, cavity-causing bacteria are infectious and can spread via saliva. If your partner has bad teeth, tell them to visit a dentist and get them filled. It's a basic hygiene requirement for both of you.

Yes, tooth decay is technically a transmissible bacterial infection. When you kiss, those cavity-causing bacteria can easily pass over. However, if you brush twice a day and use a fluoride toothpaste, you can easily prevent them from settling.

Haan na, it sounds really weird but bacteria can actually pass from one mouth to another. Just make sure both of you gargle or brush properly. It's better to be safe and keep things clean, simple.
