Is Ozone Therapy Safe? What Certification Really Means

If you have started looking into ozone therapy, you have probably noticed the internet has strong opinions about it. Some sites treat it like a cure for nearly everything, while others warn it is dangerous and unregulated. The truth sits in between, and it depends almost entirely on who is holding the ozone generator and how they were trained to use it.

At Club K Holistic Dental, we use ozone as part of a biological approach to care because it may help address bacteria and support healing without relying on synthetic chemicals. Dr. Joshua Knapton pursued formal certification in ozone therapy before offering it to patients, and that distinction matters more than most people realize when deciding whether this treatment is right for them.

Why Certification Changes the Safety Picture

Ozone is technically classified as a toxic gas when it is mishandled, which is exactly why training matters so much. A dentist who has not studied proper application methods may not know the contraindications, the correct concentration for a given tissue, or which patients should avoid the treatment altogether. Certification programs cover these details specifically so that ozone can be used without putting patients at risk.

Dr. Knapton has described his own certification process as learning how to use ozone in a way that is not toxic to the body, since the gas itself requires careful handling to stay safe. This training covers situations where ozone should not be used, delivery methods that contain exposure, and techniques that allow the gas to do its work in the mouth without escaping into the air a patient breathes.

What Trained Ozone Application Looks Like

In practice, safe ozone therapy relies on contained delivery. Dental-specific devices apply ozone gas or ozonated water directly to a targeted area, such as a cavity, a periodontal pocket, or a healing extraction site, rather than releasing it broadly. This localized approach is part of what allows ozone to work on bacteria in that one location while limiting how much gas reaches anywhere else.

Screening Patients Before Treatment

Part of a trained approach also means recognizing who is not a candidate for ozone therapy. Certain respiratory conditions and other health factors can make ozone exposure inappropriate, so a properly trained provider screens for them before proceeding. Skipping this step is one of the most common ways ozone therapy becomes risky in untrained hands.

Matching Concentration to the Procedure

Ozone concentration is not one size fits all. A dose appropriate for disinfecting a cavity preparation differs from that used near soft tissue during periotherapy for gum disease. Providers with formal training in ozone application learn to adjust concentration and exposure time to the specific procedure, which helps keep the treatment predictable.

Where the Research Currently Stands

Ozone therapy in dentistry has been studied for its antimicrobial and healing properties, and a growing body of research has looked at how it may support outcomes such as reduced bacterial counts and improved tissue healing. A 2023 literature review published through the National Institutes of Health noted that the future of ozone therapy depends on establishing safe, well-defined parameters through controlled research so providers have clear guidelines for when and how to use it. That is precisely what certification programs attempt to translate into daily clinical practice.

This research context is worth understanding because it explains why the safety of ozone therapy ultimately comes down to training rather than the substance itself. When you are evaluating any provider who offers this treatment, a few questions can help you understand how seriously they take that responsibility.

Before agreeing to ozone therapy, you may want to ask about the following:

• Certification source: Ask which organization certified the provider in ozone therapy and how recently that training took place.
• Delivery method: Ask whether the practice uses a dedicated dental ozone device designed for contained, targeted application.
• Screening process: Ask how the practice screens patients for conditions that would make ozone therapy inappropriate.

These three questions tend to quickly reveal whether a provider treats ozone as a serious clinical tool or as an add-on service with little oversight.

How This Fits Into Whole Body Dentistry

Ozone therapy is one piece of a larger philosophy at our practice, one that also includes screening the whole mouth for signs of disease rather than treating isolated symptoms. We view procedures like oral cancer screenings and ozone application as part of the same commitment to catching problems early and treating them with methods that support the body rather than working against it.

This is also why holistic dentistry tends to draw people who want more transparency about what is being used in their mouths and why. Ozone fits that pattern well when it is administered by someone who has taken the time to study it properly, because the reasoning behind each application can be explained clearly rather than treated as a mystery.
