Where do cavities start?
In science classes we learned that acid is a dangerous substance. The acids in our mouth are no different; they’re a primary cause of tooth decay, also called cavities.
The enemy in the fight to prevent cavities is plaque. Plaque is the sticky film of food and bacteria that can be hard to see and that forms constantly on your teeth.
It isn’t easy to see plaque, but if you don’t remove the plaque every day, the germs in your mouth produce acid that can eventually soften your teeth and create a hole. That’s what a cavity is: a small hole in the outer layer of your tooth.
Layers and how it affects the repair process
That hard outer layer of your tooth is called the enamel. Inside the enamel is a softer layer called the dentin. Once a cavity gets through the hard outer enamel and reaches the softer dentin, it can grow very quickly. That’s why it’s so important to have regular checkups and cleanings. Your dentist can find the cavity and fix your tooth while the cavity is still small and only in the outer enamel layer.
How do we fix your tooth?
We simply remove the decay and replace it with a filling. Fillings are a great solution when you have a cavity, but it’s much better not to get the cavity in the first place. So floss and brush daily to to keep plaque off your teeth!
