Ozone is a natural form of oxygen made up of three oxygen atoms (O₃), while the oxygen we breathe contains two oxygen atoms (O₂). This extra oxygen atom makes ozone much more reactive, allowing it to interact quickly with bacteria, viruses, fungi, and other organic substances.
In nature, ozone is produced by lightning, ultraviolet (UV) rays from the sun, and certain natural electrical processes in the atmosphere. Many people recognize its distinctive fresh scent after a thunderstorm—that clean smell is caused by small amounts of naturally occurring ozone.
In healthcare, ozone is not collected from the air. Instead, it is produced on demand from medical-grade oxygen using a specially designed ozone generator. Because ozone is highly unstable, it cannot be stored in a bottle or container. It must be generated immediately before use and is applied in carefully controlled amounts by trained healthcare professionals.
Oxygen (O₂)
Two oxygen atoms
The oxygen we breathe
Stable
Supports normal breathing
Can be stored in oxygen tanks
Ozone (O₃)
Three oxygen atoms
An energized form of oxygen
Naturally unstable
Used in controlled medical and dental applications
Must be generated immediately before use
Think of ozone as "activated oxygen." The third oxygen atom makes it more energetic, allowing it to react quickly. After it has reacted, ozone naturally breaks down and returns to ordinary oxygen (O₂).
Medical ozone is generated by passing pure medical oxygen through a controlled electrical field inside a certified ozone generator. This process converts a small portion of oxygen (O₂) into ozone (O₃), creating a precisely measured oxygen–ozone mixture suitable for clinical use.
Because ozone naturally reverts back to oxygen within a short period, it is always produced fresh at the time of treatment.
Dentists use ozone because of its broad antimicrobial properties and its ability to support a clean treatment environment. Research has shown that ozone can help reduce harmful bacteria, viruses, and fungi on treated surfaces and may support the body's natural healing processes when used appropriately.
Depending on the procedure, ozone may be used as an adjunct during:
Preventive dental care
Gum disease treatment
Root canal therapy
Dental implant procedures
Tooth extractions
Oral surgery
Professional dental cleanings
It is important to note that ozone is an adjunctive therapy, meaning it is used alongside conventional dental treatment, not as a replacement for it.
No.
When people hear the word "ozone," they sometimes think of air pollution. However, medical ozone is very different from the ozone associated with environmental pollution.
Medical ozone is:
Produced from pure medical-grade oxygen
Generated in precise, controlled concentrations
Used only for short periods during treatment
Applied directly to the treatment area using specialized equipment
Administered by trained healthcare professionals
Environmental ozone, by contrast, is formed by chemical reactions involving pollutants in the lower atmosphere and is not intended for medical use.
No.
One of ozone's unique characteristics is that it is highly unstable. After it reacts with tissues or microorganisms, it quickly breaks down and returns to ordinary oxygen.
Because of this, ozone does not remain in the body for long periods and does not leave chemical residues behind.
When generated with certified medical equipment and used according to established clinical protocols by trained healthcare professionals, medical ozone has a well-established safety profile for appropriate dental applications.
To ensure safety:
Ozone is generated immediately before use.
The concentration is carefully controlled.
Specialized delivery systems help prevent inhalation of ozone gas.
Treatment is performed only by trained professionals.
As with any dental procedure, your dentist will determine whether ozone is appropriate for your individual needs.
Modern dentistry focuses on treatments that are effective, conservative, and patient-centered. Ozone has attracted growing interest because it may help support infection control, promote a cleaner treatment environment, and complement the body's natural healing processes.
While research continues to expand, dentists in many countries incorporate ozone into selected procedures as part of comprehensive, evidence-informed dental care.
Think of ozone as activated oxygen.
Its extra oxygen atom allows it to react quickly where it is needed. Once it has done its job, it naturally changes back into ordinary oxygen, leaving no chemical residue behind.
That is why many dental professionals use ozone as an additional tool to support modern, minimally invasive, and comprehensive oral healthcare.
