Ozone therapy is very simple and extremely effective due to its use of charged oxygen. When an ozone molecule comes in contact with a pathogen, be it a virus, bacteria, protozoa, or fungus it quickly begins the process of oxidation. This rapid oxidation compromises the structure of the pathogen and kills it. The interaction between ozone and the tissues of the mouth has also been proven to increase blood flow and trigger immune responses. As a result patients who undergo ozone therapy heal much faster than those who do not.
