The Main Types of Cavities You Can Get and How They’re Treated

The Main Types of Cavities You Can Get and How They’re Treated

Unfortunately, even with proper oral hygiene cavities can make an appearance. While they’re no fun in the moment, most can be treated easily and effectively by a dentist. To understand the most common areas that cavities can occur (and how to prevent them) read on below.

Areas on Teeth Where Types of Cavities Can Occur:

Root Surface

A root cavity forms around the neck of the tooth where the gums have receded.

This particular type of cavity has a greater likelihood of happening to older adults due to decreased saliva production, age-related gum recession, and difficulty with homecare. This is why regular checkups and cleanings throughout life are so important to maintain optimal oral health.

How to Treat a Root Cavity

Because the root surface of teeth are not protected by enamel, this type of cavity is important to treat fast. Otherwise, it spreads quickly—much more so than other types.

Like many cavities, these can be treated with fillings. However, if the cavity has spread far enough to the point where it’s into the center (or close to the nerve of the tooth) then root canal therapy may be needed.

Pit and Fissure/Grooves

One of the most common types of cavities, these can occur in people of all ages and are typically found on the rear molars. This is because the bristles of our toothbrush cannot always effectively remove the debris from the small deep crevices and grooves of the back teeth.

Sealants are the best way to prevent these types of cavities. If your dentist notices that your teeth have deep grooves, they may recommend a sealant to seal off the groove and prevent future cavities.

If a cavity is detected, it can be easily fixed with a filling.

Interproximal (In Between the Teeth)

A cavity between two teeth is called an interproximal cavity. Lack of regular flossing is the main cause of this type of cavity. These types of cavities are usually not detected without a proper dental x-ray.

How to Treat an interproximal Cavity

If detected early, the most common way to treat this type of cavity is a dental filling. If the decay is extensive, then a crown or even root canal therapy may be required.

Good home care with daily flossing will help keep these areas clean and cavity-free.
