Ozone Therapy
In short
A minimally invasive approach to cavities, gum disease, and infection.
What dental ozone therapy is
Ozone is a form of oxygen. In dentistry it is used as a gas, dissolved in water, or infused in oil to disinfect and support healing. Biological dentists reach for it because it kills bacteria, viruses, and fungi on contact, which lets them clean and treat without antibiotics or harsh chemicals in many situations.
What it is used for
Dentists apply ozone for early cavities, gum disease, sensitive teeth, cleaning a tooth before a filling is placed, supporting healing after an extraction, and as part of disinfecting a tooth during root canal treatment. The goal in each case is to lower the number of harmful microbes in the area.
How it works
Ozone oxidizes the cell walls of microbes, which they cannot easily defend against, while leaving healthy tissue largely unaffected at the low concentrations used in dentistry. Because it works physically rather than through a drug, resistance is not the concern it can be with antibiotics.
What the evidence shows
Here is the honest picture. Research on dental ozone is encouraging for disinfection and for managing early cavities, but the overall body of evidence is still developing and study quality varies. For that reason most biological dentists use ozone alongside standard care rather than as a replacement for it. It is reasonable to ask your dentist what the specific goal of ozone is in your case and what the alternatives are.
What to expect
Ozone treatment is quick and generally painless, and the ozone itself does not require a needle. It is often one step within a larger visit rather than a standalone appointment.
Common questions
Is ozone therapy safe?
Used at the low concentrations and in the controlled way dentists apply it, ozone has a good safety profile. As with any treatment, it should be delivered by a trained provider who follows proper technique.
Does ozone therapy hurt?
No. The ozone application itself is painless and needle free. Any discomfort during a visit usually comes from the underlying dental work, not the ozone.
Can ozone reverse a cavity?
Ozone can help manage very early decay by reducing bacteria, and in some cases supports remineralization alongside good home care and diet. It is not a guaranteed way to reverse an established cavity that already needs a filling.
Does insurance cover ozone therapy?
Often it does not, since many plans treat it as an elective addition. Ask the practice about the cost before your visit.
Is ozone a replacement for a filling or root canal?
Usually not. Most dentists use ozone to support and improve standard treatments rather than to replace them. Your dentist can tell you where it fits in your specific plan.
