Cavities: Risk Factors and Prevention

The last thing we as Dentists want to see in our lil kiddos are cavities. Cavities are caused by the acid produced by bacteria on our teeth. The acid causes demineralization of the outer surface of the tooth leading to a hole.


There are three general categories that can lead to cavities: genetics, diet, and hygiene. The first, however, is something we have no control over and this is our genetics. We hear all the time, “Johnny, has horrible teeth and his dad gave him those” and this is completely true.


Our teeth are made up of enamel and dentin and the quality of mineralization can be different from person to person.

Even some rare genetic diseases can prevent our enamel or dental from mineralizing properly, decreasing the protective layer from acid and making those teeth more prone to cavities.


Every time your child snacks, the pH in their mouth decreases and creates an acidic environment for the bacteria to thrive.

By limiting your child’s snacking, you can prevent cavities from forming. Eating foods high in calcium, which promotes strong teeth are good to add to your diet too.

Cheese, for example, is high in calcium and a protein called casein, which also protects the enamel and makes it stronger.

You want to avoid as much sugar as possible. Sugar is what the bacteria feed on that produces the acid. Lastly, you want a diet high in fibre, as it increases salivary flow.

Your saliva contains all the minerals your teeth need to remineralize lesions forming.


You want to ensure your child is brushing two times a day for two minutes each time. We have content on both Instagram and Tik Tok @socopdo for ideas to help motivate your child. In addition to brushing, they need to floss once a day. If you aren’t flossing, you are only getting 60% of your tooth surface clean.

Finally, apply MI Paste after brushing. This is high in all the minerals needed to harden a decay that is beginning to form.

Think of it as a deep conditioner for your teeth, don’t wash it off after but sleep in it and brush it off in the morning.
