While timing is important, we also need to consider wherethe tooth is in the mouth.
What tooth or teeth is it touching? Is it another baby tooth, or is it an adult tooth? Something that patient may not know is that cavities are contagious!
If the baby tooth has a cavity and is next to an adult tooth, it is only a matter of time before the adult tooth develops a cavity as well.
Furthermore, if just one tooth has a cavity in the mouth, the rest of the teeth in the mouth are more susceptible to getting cavities, because the cavity-causing bacteria are roaming in the mouth.
Yes, this means that you can also transfer the bacteria to other people! If you are a parent and know that you may have decay in your mouth, it’s best to avoid sharing food with your kids!
