Some dental practices now offer ozone gas treatment for early-stage tooth decay. It sounds like something from a sci-fi film. But what is it — and does it actually work?
Ozone is a molecule made of three oxygen atoms. Dentists apply ozone gas to a tooth that shows early signs of decay. The idea is that ozone kills the bacteria causing the decay and can even help re-mineralise the tooth enamel.
How Does Ozone Treatment Work?
Your dentist first checks your tooth, often with magnification or X-rays, to confirm the decay is very early. A small silicone cap is placed over the tooth to seal it. Ozone gas is then pumped under the cap for around 30 to 120 seconds.
The gas penetrates the tooth surface and targets the harmful bacteria. These bacteria cannot survive in an oxygen-rich environment. After the ozone does its work, your dentist may apply a remineralising solution to help strengthen the enamel.
When Is Ozone Treatment Useful?
Ozone is only suitable for very early decay — before a cavity has fully formed. If you have a small soft spot on a tooth, ozone might stop it from progressing. It works best on smooth surfaces and the grooves of back teeth.
It is not a treatment for large cavities or decay that has reached the inner pulp of the tooth. In those cases, a filling or root canal is needed instead.
What Does the Evidence Say?
Research on ozone in dentistry has been mixed. Some studies show it can reduce bacteria and slow decay progression. Others say the effect is short-lived and that ozone alone is not enough to stop decay without good oral hygiene.
The General Dental Council does not prohibit ozone treatment, but it is not widely available on the NHS. Many private practices offer it as an adjunct to traditional care — not a replacement for it.
Is Ozone Treatment Right for You?
Ask your dentist if your decay is at an early enough stage to benefit. Ozone treatment works best when combined with better brushing, less sugar, and regular check-ups. It is one tool in a dentist arsenal — not a magic cure.
