Cavities, also called tooth decay, are a common health problem, but are cavities contagious?
Many people wonder if you can “catch” a cavity from someone else. Here’s what causes cavities, the answer to that question, and some tips for keeping your teeth healthy.
What are cavities?
Cavities are damaged spots on your teeth that eventually turn into holes. They happen when tooth decay eats away at your enamel, the hard outer layer of your teeth. Cavities are not an overnight phenomenon. They’re the result of a long process.
What Causes Cavities?
Cavities are caused by bacteria in your mouth that produce acids. These acids erode your tooth enamel, leading to decay.
Sugary foods and drinks are a major culprit because they feed the bacteria, speeding up the decay process. Also, if you don’t brush and floss regularly, bacteria thrive in your mouth.
Are cavities contagious?
Yep, in a way. Cavity-causing bacteria can spread from person to person.
Researchers have found that it’s possible to “catch” a cavity, as the bacteria that causes them (mutans streptococcus) can be transmitted. How? Usually through saliva.
Here are some common ways this happens:
- Sharing food, drinks, and utensils. Passing around utensils, food, or drinks can easily transmit the bacteria.
- Kissing. Kissing can also spread cavity-causing bacteria, especially if one person has poor oral hygiene.
- Parental transmission to children. Parents tasting food before feeding their children can pass the bacteria to their children’s mouths.
So, while you can’t exactly “catch” a cavity like you’d catch a cold, you can be exposed to the bacteria that cause them. That’s why it’s important to practice good oral hygiene and limit the sharing of saliva with others.
Preventing cavities
Even though cavities are caused by bacteria that can be passed from person to person, you can take steps to protect yourself and others.
Oral hygiene practices
- Brush your teeth twice a day with fluoride toothpaste to remove plaque and bacteria.
- Floss every day to get to the plaque between your teeth that your toothbrush can’t reach.
- Swish with an antiseptic mouthwash to kill bacteria and freshen your breath.
Dietary considerations
- Cut back on sugary foods and drinks because sugar feeds the bacteria that cause cavities.
Boosting saliva production
- Drink plenty of water to help wash away bacteria and bits of food.
- Chew sugar-free gum, especially gum with xylitol, which can prevent bacteria from growing.
Is it time for a dental checkup?
The best thing you can do for your teeth is visit the dentist regularly. Regular checkups are important for prevention and early detection. A professional cleaning will also remove plaque and tartar that your toothbrush can’t reach. Experts recommend seeing your dentist twice a year to keep your mouth healthy.
Frequently Asked Questions
Can I kiss my boyfriend if he has cavities?
Well, let’s break it down. Cavities are technically caused by bacteria, and bacteria can be transferred through saliva, which is definitely exchanged during kissing. So, yes, kissing someone with cavities could increase your risk of developing them, but it’s not a guarantee.
Think of it like this: everyone has bacteria in their mouth. It’s the balance of those bacteria, along with your oral hygiene habits and diet, that really determines your risk. If you’re diligent about brushing, flossing, and limiting sugary snacks, your mouth is likely a less hospitable environment for cavity-causing bacteria, even if you’re swapping spit with someone who has a few cavities.
Ultimately, it’s up to you! Don’t let the fear of cavities ruin your love life, but maybe encourage your boyfriend to see a dentist! And keep up with your own good oral hygiene habits. A little extra brushing never hurt anyone, right?
Conclusion
Because the bacteria that cause cavities can be transmitted from person to person, cavities are, in a way, contagious. The best way to protect yourself is to practice good oral hygiene and see your dentist regularly.
