The 3 Different Types of Cavities

Chances are you’ve had a filling, or at least know someone who’s had one. They’re a pretty common occurrence today. But, did you know there are three types of cavities, and each one can have a slightly different method of treatment?

To help you understand the zinging pain in your mouth, we’ll cover the three types of cavities and how we can fix them.

Root Cavities

Different from a root canal, root cavities are blemishes on the surface of the root of your tooth. That may seem strange, as your gums usually cover up the root of your tooth stopping plaque from forming there. That’s why these types of cavities are only common in older adults, who are more likely to have gum disorders, like receding gums. Once those gums recede enough to reveal the root, they are just as likely to get a cavity as any other part of the tooth.

Root Cavity Treatment

Because the root of a tooth doesn’t have much enamel, tooth decay can spread quickly there. If it is caught early and the cavity is shallow enough, a dentist can simply fill the cavity and move on. However, often these types of cavities require a root canal as the decay can quickly find its way to the root.

Pit and Fissure Cavities

This is the most common type of cavities, occurring on the chewing surface of the molars. These are particularly a problem for people who don’t brush their teeth enough, as it’s easy for bits of food to get stuck in the crevices of molars.

Pit and Fissure Cavity Treatment

If caught early, these types of cavities can sometimes be treated with sealants or some types of fluoride. However, if left too long, the dentist will have to remove decay and repair it with a filling. Though not as quick to spread as a root cavity, pit and fissure cavities can also require root canals, or even a crown, if left untreated for a long period of time.

Smooth-Surface Cavities

These cavities affect the smooth surfaces on the side of your teeth, typically along the exterior surface of the teeth. These are the least common cavities, as they take a long time to form.

Usually, a smooth-surface cavity is a clear sign the patient has not practiced good oral hygiene for quite some time.

Smooth-Surface Cavity Treatment

Because these are slow growing cavities, they are easily treatable. Often they can be fixed with the help of fluoride treatments, such as you would find in toothpaste. However, if left too long, they will need a filling as well.
