Caries treatment

Using a DIAGNOdent pen that can diagnose cavities more accurately, we will treat after diagnosis with a laser whether it is colored or cavities. CO (tooth requiring observation) may worsen the holding of teeth by scraping it in a state where it does not need to be scraped, so we will use it to judge whether preventive treatment or early treatment is good.

Caries on the adjacent surface (between teeth) is diagnosed by shining light with a device called a transilluminator. Even if it looks like there are no holes, the cavities may be progressing from the side. .. Judgment is made by looking at the light transmittance.

Natural teeth are the strongest, and teeth that have been shaved once do not have self-healing power like other tissues and do not return to their original state. Even if it is easily scraped, there is a high risk of secondary caries (the treated tooth becomes cavities again) due to the deterioration of the material and the wear of the tooth after a few years. ..

At our hospital, we are focusing on preventive measures so as not to scrape as much as possible.

Periodontal disease treatment

Periodontal disease, which is a chronic disease in the mouth that is said to affect more than 80% of adults, has almost no symptoms at the initial stage and is acute when the immune system is weakened and tired. It often turns into swelling and pain.

When it becomes moderate to severe, symptoms such as bleeding, bad breath, and loose teeth appear when using a toothbrush.

Thorough biofilm removal and plaque control on your own are important treatments.

The flow of treatment for periodontal disease is determined by medical insurance.

① Periodontal disease examination X-ray

The depth of the groove between the tooth and gum, called the periodontal pocket, is measured with a graduated instrument called the probe.

It is a measure that periodontal disease is progressing within 3 mm and 4 mm or more in a healthy state, and the state of inflammation is also checked by the presence or absence of bleeding. X-rays check the condition of the bones that support the teeth, called the alveolar bone, and as periodontal disease progresses, the condition of the alveolar bone is lowered.

② TBI (brushing instruction) scaling

The most important treatment for periodontal disease is your own plaque control. A dental hygienist will check the cleaning method using various cleaning tools and give guidance on how to polish.

After that, the biofilm that does not come off with a normal toothbrush is removed using water and vibration using a machine called a scaler.


The deep part of the periodontal pocket is anesthetized and carefully removed using a special instrument called a curette.

This is the stage called basic periodontal therapy.

It takes a lot of time because the whole mouth is divided into 6 blocks, but you have to remove the dirt that you can't reach with your usual toothbrush.

Periodontal disease gradually progresses.

④ Re-evaluation

  Check the healing condition of the gums. If it is good, move to maintenance, and if treatment is still needed, move to surgical treatment, regenerative treatment, and sterilization treatment.

Periodontal regeneration treatment (ligros)

Regros has been approved for insurance as the world's first periodontal tissue regeneration drug.

After cleaning the bone surface destroyed by periodontal disease during periodontal surgery, cells are activated and the regeneration of periodontal tissue is promoted by placing a drug. Previously, a protein called Emdgain was used, but since 2017 it has been approved by insurance.

* Indications are limited, so it may not be effective in all cases.

In addition to the usual basic periodontal therapy, our hospital proposes measures using saliva tests, halitosis tests, periodontal disease bacteria tests, and supplements.

Oral surgery

Simple minor operations and tooth extractions such as tooth fracture and dislocation, wisdom tooth extraction, cyst removal, zonule resection, and initial treatment of jaw arthritis are supported, wisdom tooth swollen, wisdom tooth detached, jaw We also support first-aid measures such as pain, tooth hits, etc.

Wisdom tooth trouble

Wisdom teeth are permanent teeth that grow around the age of 18, and if there is not enough space in the jaw, they will not be able to grow completely and will be in a state where the head is half raised, or it will come out diagonally or be buried sideways. It may have an adverse effect on the next tooth.

If it grows normally, it is not necessary to extract it, but if it has an adverse effect, consider early tooth extraction.

Cases where wisdom teeth should be removed

1 When growing diagonally or sideways

2 If the toothbrush does not reach and you have cavities

3 Not involved in meshing (when twisted)

4 When only a part of the head is out

5 When the teeth are pushed and the teeth are not aligned properly

Cases where you don't have to pull out wisdom teeth

1 It grows normally and is also involved in meshing.

2 The toothbrush is in perfect condition

3 When completely buried in the bone

Metal-free treatment is a treatment that does not use any metal.

In dental treatment, the use of metal with durable quotient force has been adopted, but in recent years, CAD / CAM crowns using hybrid ceramics have been approved for the molars in insurance medical treatment as well.
