If you've heard the term "ozone therapy" and wondered what it means for your dental health, you're not alone. At our practice in Thousand Oaks, we believe that how we treat your teeth, gums and jawbones should support your overall health — not undermine it. Ozone therapy is one of the most powerful and natural tools we offer. Here are the questions we hear most often.
What is ozone, and how does it work?
Ozone (O₃) is a supercharged form of the oxygen we breathe. While ordinary oxygen has two atoms (O₂), ozone has three. That third atom is chemically unstable — and when ozone contacts a bacterial cell, virus, or fungus, it oxidizes and destroys it on contact, then reverts harmlessly back to oxygen and water. No chemical residue. No systemic toxicity. Just oxygen and water.
That clean, electric smell after a thunderstorm? That's ozone, produced by lightning. In our office, a medical-grade generator replicates that same process with precision. Ozone is produced on-site, used immediately, and reverts to oxygen within about 40 minutes — so it is never stored. Ozone therapy has been used in medicine for over 150 years and in dentistry since the 1930s.
What can ozone therapy treat?
Ozone is remarkably versatile. At Albert Chow DDS, we use it for:
- Tooth decay — Eliminates decay-causing bacteria and re-mineralizes teeth from within. Early-stage cavities can sometimes be addressed without drilling using ozone oil, ozone water, or ozone gas.
- Gum disease — Applied directly into infected pockets to reduce bacterial load and inflammation more effectively than conventional irrigation alone.
- Root canals — Disinfects the canal system and reduces post-treatment pain.
- Tooth sensitivity — Ozonated materials have shown real promise managing dentinal hypersensitivity.
- Soft tissue conditions — Effective against herpes lesions, canker sores, thrush, and traumatic wounds.
- Preventive care — Full-arch tray treatments reduce overall bacterial burden, especially for high-risk patients.
How is ozone administered? Is it safe and painless?
Ozone therapy is one of the most comfortable treatments we offer — non-invasive, typically painless, and fast. At our practice, we use all three forms of therapeutic ozone:
- Ozone gas — The most common form. Applied directly to a tooth, into a gum pocket, or delivered via a metal canula into the jawbone. As a gas, ozone can penetrate areas no instrument can reach.
- Liquid ozone (ozonated water) — Used for irrigation of surgical sites, flushing periodontal pockets, and mouth rinsing. Highly effective at eliminating bacteria while being completely biocompatible.
- Ozone oil (ozonated olive oil) — Provides a sustained-release antimicrobial effect. Especially useful for soft tissue healing and as an at-home care option between appointments.
As for safety: ozone selectively destroys pathogens like viruses, bacteria, and fungi because they have no antioxidant defenses, while healthy human cells are equipped with antioxidant systems that protect them. It leaves no residue, creates no antibiotic resistance, and reverts to pure oxygen. High concentrations of inhaled ozone can irritate the respiratory tract, which is why we use sealed delivery systems and proper ventilation. This is not a treatment to attempt at home with consumer devices.
Why does this matter beyond my mouth?
Oral bacteria don't stay confined to the mouth. Research has linked oral pathogens to cardiovascular disease, diabetes complications, joint inflammation, and brain infections. The same bacteria that cause tooth decay have been found in arterial plaques associated with atherosclerosis. This is central to Dr. Chow's integrative philosophy of care — when we eliminate oral infection at the microbial level, we are supporting systemic health, not just your smile.
Setting the Record Straight: Common Misconceptions
A fair amount of misinformation circulates about ozone therapy. Here's what we actually see in practice.
"Ozone reverses decay, so I won't need drilling."
Partly true. For early-stage surface lesions, ozone can sometimes eliminate the need for a filling entirely. But once decay has progressed into the dentin, the damaged tooth structure still needs to be removed mechanically. Ozone stops the infection and makes drilling more conservative — the two work together, not in opposition.
"Ozone works in a single treatment."
Not typically. Effective ozone therapy — particularly for gum disease or remineralization — requires a series of applications. Bacterial biofilms reform, tissues heal progressively, and remineralization is gradual. We will always lay out a realistic treatment plan before we begin.
"I might be allergic to ozone."
Not possible. Ozone is O₃ — a form of oxygen. Allergies require the immune system to identify a foreign protein; oxygen molecules don't qualify. Some people experience airway irritation from inhaling high concentrations, which is why we use sealed delivery systems — but that is a chemical sensitivity, not an allergy. No allergy test is needed before treatment.
"Ozone replaces all conventional dental care."
Ozone is a powerful adjunct, not a replacement. It makes other treatments more effective and less invasive, but a comprehensive plan may still include cleanings, restorations, or periodontal therapy. We use every tool available — ozone included — in service of your best outcome.
"Ozone is toxic — it's a pollutant."
Ground-level ozone in smog can irritate the lungs — but that's a matter of concentration, duration, and exposure route. In our office, ozone is delivered at controlled therapeutic concentrations and reverts to pure oxygen almost immediately. Decades of clinical use in Europe and South America have produced no evidence of systemic toxicity under proper protocols.
Is ozone therapy right for me?
Ozone therapy is appropriate for most patients — from children with early decay to adults who want to manage gum disease, cavitations, or tooth infections with a more conservative approach to care. It is especially valuable for patients who:
- Prefer to minimize drilling and traditional restorations
- Have early-stage cavities that may respond to remineralization
- Are managing chronic periodontal disease
- Are immunocompromised and benefit from reduced bacterial load
- Avoid root canals in non-abscessed teeth
