Can You Reverse a Cavity?

Cavities are among the most common health problems affecting children. Data from the Centers for Disease Control and Prevention (CDC) shows that over half of children between the ages of six and nineteen has had at least one cavity in a permanent tooth.

But the biggest question is, is it possible to reverse a cavity? The straight answer is no; a cavity cannot be reversed. But again, this will depend on the severity of your cavity. What does this mean? Read on to learn more.

What Is a Cavity?

A cavity is a hole left in the tooth caused by decay. Decay forms as a result of plaque, a bacteria-filled film left on the teeth after eating. When dental decay is not treated, it advances to form permanent holes or openings in your child’s mouth, usually referred to as dental caries or cavities.

Cavities don’t happen overnight; they develop over time. Here are the stages of tooth decay that facilitate the development of a cavity:


Demineralization is the initial stage of tooth decay. It happens when the minerals found in teeth, such as phosphorous and calcium, are lost due to an acid attack. This occurs due to increased acidity in the mouth, the consumption of acidic foods, or poor oral hygiene. Demineralization can make your child’s teeth softer and prone to tooth decay.

Enamel Decay

When the bacteria in the mouth continue to feed on the plaque, it produces acids that further break down the enamel of the teeth.

Dentin decay

This occurs when tooth decay damages dentin (a soft tissue under the enamel). When dentin is damaged, it can cause cavities and pain.

Pulp decay

The dental pulp is the innermost part of the tooth that hosts nerves and blood vessels. Once the pulp is exposed, bacteria in the mouth can invade it, leading to inflamed tooth pulp.

Is It Possible to Reverse a Cavity?

Generally, it is possible to reverse a cavity only if identified at the first stages of the demineralization phase. To do this, your baby must practice proper oral hygiene to help restore the lost minerals and prevent decay. This includes:

  • Brushing their teeth at least twice a day and flossing every night
  • Increase their exposure to fluoride
  • Reduce the amount of sugar your child consumes
  • Take your child to a dentist at least twice a year

Sometimes, cavities cannot be prevented even with the best oral hygiene. In this case, you’ll need to seek treatment. Depending on the severity of your child’s cavity, your dentist may recommend dental fillings, crowns, a root canal, or an extraction as a last resort if the tooth can’t be saved.
