How Do Cavities Form?

Posted in Fillings

No one likes hearing that they have a new cavity and need yet another filling. It could feel like you’re chasing them down every dental visit.

What makes teeth prone to growing spots of decay?

The Culprits of Tooth Decay

You could chalk up the cause of cavities to bacteria. A cavity isn’t just one rotten spot – it’s the result of a high concentration of cavity-causing bacteria. These bacteria are everywhere in the mouth, but when they stay in one spot too long, they’ll cause a cavity.

These bacteria produce a waste product that’s acidic to teeth. So as the germs thrive on a tooth, they gradually eat their way through it. The acid wears down tooth enamel and creates a cozy little hole for the bacteria to live in.

And boom! A cavity.

A cavity finds it’s way straight through the tooth to the soft inner chamber of nerves. At this point, you’re looking at an infection called an abscess.

Where Does Sugar Come In?

Sugar and other simple carbohydrates can have an acidic effect on tooth enamel. Exposing your teeth to lots of sugar and sticky carbs will definitely speed up the cavity process by weakening your teeth.

What’s more, cavity-causing bacteria live off of the sugar you eat. Their only job is to transform sugar into acid – the acid which permanently damages your teeth.

Repairing Cavities

First, your dentist has to clean out all the damaged structure left behind by a cavity. All traces of infected tooth are cleaned away and the delicate hole is sealed up with a filling.

Ask your dentist to find out what else you can do to prevent cavities.
