Ozone Therapy

Ozone therapy — gentle care for your comfort

Natural and painless ozone treatment for disinfection, accelerated healing and oral tissue regeneration.

About This Treatment

Dental ozone therapy uses ozone (O₃) — a naturally occurring molecule made of three oxygen atoms — as a powerful antimicrobial and regenerative agent. Applied as a gas directly to the treatment area, ozone eliminates bacteria, viruses and fungi without leaving chemical residues, stimulates healing and promotes tissue regeneration. It is a painless, non-invasive treatment that is safe for all ages.

Challenges That Ozone Therapy Addresses

Ozone therapy is a natural and painless solution for multiple oral health challenges: from early cavities and periodontal disease to root canal disinfection and post-surgical healing.

Gas + Ozonated Water

Two Forms of Ozone, One Goal: Your Comfort

We use ozone in two complementary forms — as a targeted gas and as ozonated water — so every procedure is gentler, safer and more comfortable for you.

  • Cavities Without the Drill

    A precise puff of ozone gas kills bacteria inside early decay and lets your tooth repair itself naturally. No drilling, no anaesthesia, no stress.

  • Healthier Gums, Less Discomfort

    Ozone gas reaches deep into periodontal pockets while ozonated water gently rinses and soothes the gumline — clearing infection from both sides.

  • Safer, Cleaner Root Canals

    Ozone gas disinfects every microscopic canal, and ozonated water flushes away debris — together they reach places conventional rinses miss, for a more predictable outcome.

  • Better Implant Success

    Ozone gas disinfects the implant site before placement, while ozonated water irrigates and prepares the surrounding tissues — protecting your investment from day one.

  • Fast Relief from Mouth Sores

    Gas application targets canker sores and cold sores directly, while ozonated water rinses provide soothing, whole-mouth relief. Most patients feel better within minutes.

  • Quicker Recovery After Surgery

    After extractions or bone grafts, ozone gas reduces infection at the surgical site and ozonated water rinses keep the area clean — less swelling, faster healing.

The Science Behind Your Comfort

Why Ozone Works So Well

Ozone is not just gentle — it is backed by science. Here is how it takes care of you at a biological level.

  • Eliminates Harmful Bacteria Instantly

    Ozone destroys microorganisms by breaking apart their cell walls — a natural mechanism that bacteria simply cannot outsmart or resist.

  • Floods Your Tissues with Oxygen

    As ozone breaks down, it releases fresh oxygen directly into your tissues, improving circulation and creating conditions where infection cannot survive.

  • Activates Your Immune System

    Ozone switches on your body's natural defence cells, calms inflammation and helps your immune system work more efficiently where it matters most.

  • Rebuilds Tissue From Within

    By stimulating collagen production, new blood vessel growth and cellular repair, ozone helps your mouth regenerate stronger and faster.

Simple and Quick

What to Expect During Your Visit

The entire process is simple, fast and virtually painless. Most patients are surprised by how easy it is.

  1. 01

    We Listen and Assess

    Your dentist examines your situation, explains exactly how ozone can help and tailors the treatment to your specific needs.

  2. 02

    A Gentle Application

    Depending on your treatment, we use ozone gas directed through a sealed handpiece and/or ozonated water for gentle irrigation. You feel nothing — or at most a light warmth or a soft rinse.

  3. 03

    You Are Done — Just Like That

    No anaesthesia wearing off, no recovery time. You walk out of the clinic ready to enjoy the rest of your day.

Safe for Everyone

Gentle Enough for Your Whole Family

From your child's first filling to your parents' dental care — ozone therapy is safe and beneficial at every age.

  • Children

    No drill, no needles, no tears. Ozone treats cavities in baby teeth gently, making the dentist a positive experience from the start.

  • Adults

    Whether it is a routine cleaning or a complex procedure, ozone makes every visit more comfortable and every result more predictable.

  • Seniors

    Especially valuable when healing is slower. Ozone boosts regeneration for root cavities, dry mouth complications and post-surgical recovery.

  • Patients with Health Conditions

    Particularly beneficial for diabetics and immunocompromised patients, who gain the most from ozone's powerful, drug-free antimicrobial protection.

A Word from Our Clinical Director

“What I love about ozone therapy is what it means for our patients. They sit down expecting the usual dental stress and discover that treatment can actually be comfortable. Children stop fearing the dentist. Adults who postponed care for years finally come back. And clinically, we see faster healing, fewer complications and better long-term results. Ozone is not just a technology — it is a better way to care for people.”

FAQ

Frequently Asked Questions

Find answers to the most common questions about this treatment.

What is dental ozone therapy?

It is a gentle treatment that uses ozone — a natural gas made of three oxygen atoms (O₃) — to disinfect, heal and regenerate your mouth. Ozone is one of nature's most powerful antimicrobials: it eliminates bacteria, viruses and fungi in seconds, leaves no chemical traces, and simply breaks down into the oxygen you breathe. At our clinic, we apply it as a medical-grade gas through a small sealed handpiece — quickly, precisely and painlessly.

Does ozone therapy hurt?

Not at all. Most patients feel absolutely nothing. Some notice a very slight warmth. Because no anaesthesia is needed in most cases, there is no numbness afterwards either — you leave the clinic feeling completely normal and ready to carry on with your day.

Can ozone therapy replace the drill for treating cavities?

For early cavities that have not yet formed a hole in the tooth, yes. Ozone kills the bacteria causing the decay and allows your tooth to remineralise naturally. Studies show success rates above 80% for early-stage cavities treated with ozone. For more advanced cavities, we still need a conventional restoration, but ozone makes the procedure cleaner and the outcome more predictable.

Is ozone therapy safe?

Extremely safe. Ozone is a natural molecule that breaks down into oxygen within minutes. Our equipment has multiple safety systems, including sealed handpieces and ozone neutralisation units. There are no known allergic reactions to ozone, and it is safe for children, the elderly and pregnant women (topical application). The only contraindications are G6PD deficiency and uncontrolled hyperthyroidism.

Who can benefit from ozone therapy?

Almost everyone. Children love it because there is no drill or needle. Adults appreciate the comfort and faster healing. Seniors benefit from improved regeneration. And patients with conditions like diabetes gain extra protection from ozone's drug-free antimicrobial action. It is truly a treatment for the whole family.

How many sessions will I need?

It depends on what we are treating. Early cavities may need 1 to 4 sessions spaced a few weeks apart. Gum disease treatment typically involves 3 to 6 sessions. For disinfection during a root canal or surgery, ozone is applied in a single visit as part of the procedure — no extra appointments needed.

Can bacteria become resistant to ozone?

No — and this is one of ozone's greatest advantages. Unlike antibiotics, ozone destroys bacteria by physically breaking apart their cell walls. There is no genetic mechanism for bacteria to develop resistance to this. In an era of growing antibiotic resistance, this makes ozone an incredibly valuable tool.

Is ozone therapy scientifically proven?

Yes. Over 1,500 scientific publications support the use of ozone in medicine and dentistry. Controlled studies confirm its effectiveness for reversing early cavities, disinfecting root canals, treating gum disease and accelerating healing after surgery. It is recognised by the International Ozone Association and used in top dental clinics across Europe.

How does ozone help me heal faster?

Ozone works on multiple levels at once: it increases oxygen delivery to your tissues, activates growth factors, stimulates collagen production, improves blood flow and reduces inflammation. The clinical result is healing that is 30-50% faster than normal, with a lower risk of complications. Patients often tell us they were surprised by how quickly they recovered.

Can ozone therapy be combined with other dental treatments?

Absolutely — and that is often the best approach. Ozone enhances the results of fillings, root canals, cleanings, surgeries, implants and even teeth whitening. At our clinic, we integrate ozone into our biological, integrative dentistry philosophy to give you the best possible outcome from every procedure.
