An early cavity can sometimes be reversed if a hole in the tooth has not yet formed. Once tooth structure has been lost, the missing enamel cannot grow back, and dental treatment is needed to repair the damage and prevent the decay from progressing.

When Can Early Tooth Decay Be Reversed?
Early tooth decay may be reversible while the enamel surface is still intact. At this stage, acids produced by bacteria in plaque have begun removing minerals from the enamel, but a physical cavity has not yet formed.
When decay is caught at this early stage, restoring minerals to the weakened enamel may help strengthen the tooth and stop the decay from progressing. This process is known as remineralization.
How Does Tooth Remineralization Work?
Tooth remineralization is the natural process of replacing minerals lost from weakened enamel. Calcium and phosphate, naturally present in saliva, help restore mineral content, while fluoride promotes remineralization and makes enamel more resistant to acid.
Parents can help encourage remineralization by:
- Brushing with fluoride toothpaste: Have children brush twice a day using the right amount of fluoride toothpaste for their age.
- Limiting frequent sugar: Reduce frequent sugary foods and drinks that contribute to mineral loss.
- Keeping up with dental visits: Regular dental visits allow weakened areas of enamel to be monitored.
- Using additional fluoride when recommended: Depending on a child’s age and cavity risk, professional fluoride varnish or, in some cases, a prescription-strength fluoride product may be appropriate.
When SDF May Help Stop Tooth Decay
Silver diamine fluoride (SDF) treatments may be used in certain situations to manage active tooth decay. Using SDF to arrest an early cavity means stopping the decay from progressing rather than rebuilding tooth structure that has already been lost.
SDF is applied directly to the affected area and may be an option for some children when a minimally invasive approach is appropriate. One important consideration is that SDF permanently darkens the decayed portion of the tooth.
At Stanley Pediatric Dentistry, we can evaluate your child’s cavity and determine whether SDF or another treatment is appropriate for their needs.
When Does a Cavity Need Treatment?
Once decay has created a hole in the tooth, remineralization cannot repair the lost enamel, and dental treatment may be needed. Depending on how far the cavity has progressed, treatment may range from minimally invasive approaches to a filling or crown.
Our goal at Stanley Pediatric Dentistry is to remove or stop the decay, restore damaged tooth structure when necessary, and preserve the tooth whenever possible.
FAQs
How quickly can a cavity get worse in a child?
There is no set timeline. How quickly tooth decay progresses depends on factors such as a child’s oral hygiene, diet, fluoride exposure, cavity risk, and the location of the decay. Regular dental visits can help monitor early changes before they become more extensive.
Are cavities more common in certain children’s teeth?
Yes. Cavities commonly develop in the pits and grooves of back teeth, where food and plaque can collect and brushing can be more difficult. Dental sealants may be recommended to help protect these cavity-prone surfaces.
Can a cavity in a baby tooth be left untreated?
Not necessarily. Baby teeth may remain in place for years, and untreated decay can become more extensive during that time. Whether treatment is needed depends on the tooth, the extent of the decay, and how long the tooth is expected to remain.
Catch Tooth Decay Early
Because early decay doesn’t always cause pain, regular dental visits give us a chance to catch cavities before they progress further.
