June 11, 2026

While there are various treatment options out there to address tooth decay, have you ever wondered if there was an even more conservative option? Ozone therapy is a treatment that can be used to address several oral health issues, but what kind of impact can it have on cavities? Can it take the place of traditional dental fillings? Continue reading to learn more about ozone therapy and its potential.

How Does Ozone Therapy Work?

Ozone is a molecule that is comprised of three oxygen atoms bonded together. Unlike the oxygen that we breathe, which is composed of two oxygen atoms, ozone cannot be inhaled. However, it can still be used to support oral health because of its ability to eliminate harmful bacteria. When ozone is applied to tissues in the mouth, it results in transient oxidative burst,” Since the bacteria in the mouth cannot defend themselves against this reaction, they die.

How Can Ozone Therapy Treat Cavities?

One of the great things about ozone therapy is the fact that it can fight against cavities. Here is how the process works:

  • 1. Diagnosis: The dental professional identifies early decay.
  • 2. Ozone: Medical-grade ozone gas is applied directly to the site of decay using a specialized handpiece.
  • 3. Disinfection: Ozon eliminates bacteria, viruses, and fungal spores within seconds.
  • 4. Remineralization: A natural mineral or ozone-infused serum is applied to strengthen enamel.

Who’s a Good Candidate for Ozone Treatment?

Ozone therapy can be used for a variety of different reasons. It may be beneficial to you if you have the following dental issues:

  • Gum Disease: Gum disease is an infection of the gum tissue. When ozone is applied to the pockets between the gums and teeth, it can help fight the infection and encourage healing.
  • Cavities: Most of the time, cavities are treated by removing decayed tissue and filling the tooth. Ozone can be used to kill bacteria inside a tooth, minimizing the need for drilling.
  • Infected Tooth: Root canal treatment is necessary when a tooth is infected. Ozone can be used to thoroughly sterilize the tooth’s interior, reducing the probability of needing root canal retreatment in the future.
  • Other: There has been evidence supporting the use of ozone to reduce dental sensitivity, promote healing after extractions, and more!

  • Treatment is non-invasive and painless
  • When administered by a trained professional, ozone therapy is perfectly safe
