Does Kissing Cause Cavities?

Even with diligent dental hygiene, our mouths are full of bacteria. Many of these bacteria are totally harmless; some of them are even beneficial. Unfortunately, there are a good few of these microorganisms that can cause tooth decay and gum disease.

Cavities are caused by a build-up of harmful bacteria. This bacteria excretes acid that erodes enamel by eating the residual sugars and starches that adhere to our teeth after eating. If you don’t practice good oral hygiene and clean your teeth regularly, this bacteria will inevitably cause cavities.

So, can kissing give me cavities?

Similar to any other virus or bacteria, these little organisms don’t tend to stay put. This means that they can absolutely be transferred from one mouth to another. In reality, bad bacteria can be shared in many more ways than just kissing. Sharing utensils or straws, splitting food or accidentally using someone else’s toothbrush will have similar results in terms of sharing bacteria.

What’s the good news?

While there is some truth to the rumour that a smooch could give you cavities, there are plenty of ways to keep this in check. If you practice effective oral hygiene and are conscientious about brushing your teeth, then you don’t need to be very concerned about passing harmful bacteria to others with your kisses. This means making sure both your teeth and your tongue never miss a brush twice daily.
