The treatment of caries without drilling and pain?

Caries is an infectious disease. Bacteria, which are normally present in the mouth, convert all foods (sugar) into acids, which attack and disintegrate dental tissue. This leads to the formation of small cavities invisible to the naked eye. The bacteria enter these cavities and further damage dental tissue, which decays after some time and the cavities become visible. To prevent tooth decay, these bacteria should be destroyed. This is called an anti-infective therapy. In conventional caries treatment, all rotten dental substance is removed by a dental drill, which always destroys a part of the healthy tissue and may irritate nerves. This can be later felt as pain. After the decayed tissue is removed, a cavity, whose size depends on the size of the affected part of the tooth, remains. The patient can feel it as a hole in their tooth. For aesthetic and functional purposes, it should be filled with an adequate material.

Ozone destroys 99.99% of caries-causing bacteria within 20 seconds. The patient does not feel any pain. Ozone disinfects the affected portion of the tooth and thus prevents its further decay. The carious tooth should be then hardened. This means that the tissue components softened by bacteria and acids should be reintegrated into the dental tissue. This is called re-mineralization. It is achieved by special fluids rich in minerals that are placed on the tooth immediately after the action of ozone. We shall also give you special toothpaste and a mouth rinse, which contain all the essential minerals that your body needs to repair the decayed area. An ozone treatment does not require an anesthetic, drilling or filling, i.e. the healthy dental tissue is not sacrificed.

When can HealOzone be used to treat caries?

HealOzone can be used in both adults and children for the treatment of caries of deciduous and permanent teeth. Its efficiency has also been proven in the treatment of sensitive tooth canals since ozone, by destroying bacteria, enables the minerals from the saliva to enter carious dentin and close the canals thus significantly reducing the sensitivity of nerves.

Can caries be treated without drilling and filling?

Sometimes, drilling cannot be avoided. Caries tends to spread and it can destroy inter-dental tissue to a large extent, while leaving the dental surface completely intact. This is the so-called occlusal caries. In this case, the hole made in the tooth should be minimal to allow the ozone to reach the diseased tissue. However, the healthy dental tissue remains spared to a far larger extent than in conventional treatment. If the caries is very deep, drilling cannot be completely avoided. However, in conventional therapy, the dentist can damage the nerve with a dental drill, which often results in the treatment of root canals. This can be avoided by using the ozone therapy.

How can a dentist know how deep my caries is?

Visual recognition and use of a probe are the most important in diagnosing caries. However, this traditional method reveals only 20% of teeth with deep caries with an intact dental surface. In these cases, a laser is used. Dental tissue changed due to caries fluoresces and this fluorescence of bacteria is proportional to the size of the destroyed dental substance. The instrument DIAGNOdent measures the fluorescence by using a laser. The dentist reads the obtained values and determines further therapy: ozone therapy or minimum drilling, if the caries is very deep.

How long should ozone be applied to the affected tooth?

Depending on the depth of the caries, it is applied for 30 to 60 seconds.

What follows the HealOzone therapy?

Patient compliance is important for a successful therapy. The patient receives an “at-home care kit”, which consists of toothpaste and a mouth rinse rich in minerals to accelerate self-healing. Patients should use these intensively for about six weeks.

When do I need a checkup?

Depending on the measured depth of the caries, the patient should come for a checkup after six to twelve weeks. In some cases, the therapy should be repeated and the patient checked after about three months.

What if the checkup shows that the therapy has not been successful?

When the clinical examination and the measurement performed by DAGNOdent confirm that the caries has been healed, the patient should see the dentist in six months. However, he should continue with thorough oral hygiene: brushing teeth at least three times per day and reducing the intake of sweets.

If drilling was necessary prior to the HealOzone treatment or if the dental surface was already destroyed, the dentist usually fills this small “hole” with a temporary filling, which is also rich in minerals. When the patient comes for a checkup, the dentist removes this material and evaluates the action of ozone and minerals both clinically and by applying the DIAGNOdent. If results are satisfactory, the tooth is filled with a filling, which is often smaller than a conventional filing.

Is it true that the HealOzone therapy does not hurt?

Therapy is simple and painless.

Is the application of ozone dangerous?

No, due to the design of the HealOzone system, only the treatment site on the tooth is exposed to the ozone. Once the treatment is completed, the HealOzone system coverts the ozone back into oxygen.

What does the procedure look like? What should I expect?

The procedure consists of four steps – as depicted in the photos on the right of this page.


- fissure caries
- root caries
- smooth surface caries
- initial therapy of caries in children
- deep caries
- occlusal caries
- sterilisation prior to sealing of fissures
- sensitive dental canals
- therapy of aphthae, herpes

As we use various materials and provide various services, we have adopted an individualized patient approach. Therefore we cannot provide a common price list. During the examination, you will be informed about planned course of therapy, necessary treatments and type of therapy, necessary treatments and type of materials to be used.
