Ozone is a gas, the application of which causes a considerable drop in the amount of bacteria responsible for tooth decay or gum diseases. The use of ozone in emerging tooth decay on the surface of a tooth, drilling is avoided as we can apply ozone and engage the re-mineralizing system. This procedure makes the whole treatment absolutely painless and moreover, is the most effective way of treating the tooth in the first place. The application of ozone is done by the most up-to-date HealOzone generator. Through a special mouthpiece, the ozone is applied onto the tooth surface and the whole procedure lasts approximately 20 to 40 seconds. Analogically, we can apply ozone to cure gum inflammation, mouth ulcers etc which enables us to shorten the period of treatment rather significantly.
