Periodontal Therapy

Periodontal Therapy In our clinic,in order to preserve your natural teeth,we continuously fight the periodontal disease progression using surgical microscopes to thoroughly treat your teeth one by one.

As the Chinese character implies, periodontal disease refers to a "illness" "surrounding" the "tooth". Although the tooth is supported by the surrounding organization (periodontal tissue) of teeth, such as the gum, a periodontal membrane, and an alveolar bone, the state where the periodontitis bacillus contained in the dental plaque has caused an inflammation of the surrounding organization of the tooth is called periodontal disease. It is believed that more than 80 percent of Japanese adults suffer from chronic periodontitis, demonstrating the most frequent cause for tooth extraction and since it is comparatively hard to be aware of its progression, we screen for the disease and recommend a medical treatment as early as possible.

Illustration of a periodontal disease progression

Healthy tooth
  • The gum is firmly tightened
  • Coral pink color, showing elasticity
  • No bleeding by brushing etc
Tooth inflammation
  • Red spots show up on the gum
  • Gums bleed when tooth is brushed
  • The tooth feels loose
  • Itchiness of the gum
Tooth inflammation〜First to middle stage
  • The gum sometimes swells and turns red
  • Blood and pus comes out of the gum
  • Bad breath is noticeable
  • The tooth permeates when a cold food is eaten (hyperesthesia)
  • The gum and tooth diminish
Periodontitis terminal stage
  • Blood and pus comes out abundantly of the gum
  • The tooth is loosened
  • Severe bad breath
  • Difficult to bite in food

Periodontal disease treatment procedure

Fundamental periodontal treatment explained step by step.

Step.1 in clinic

Symptoms screening

We proceed with a check up to confirm the dental plaque formation.
Then, we measure the depth (oscillation degree) of the gap called "periodontal pocket" between the teeth and the gums and the presence of bleeding and looseness using an instrument called a probe, inspecting for gingivitis or periodontitis symptoms.
If the depth of a periodontal pocket is 3 mm or less, it shows normal or slight inflammation, 4~6 mm show a medium degree, and above 7 shows a serious degree of periodontitis.

Step.2 in clinic

Tooth brushing guidance

The purpose for teaching each patient tooth brushing guidelines through daily home care (plaque control) is to thoroughly remove the dental plaque that becomes a nest for pathogenic organs (bacillus) which cause chronic periodontitis.
This is the most important step against the progression of the disease.
Since every patient has particular habits in brushing his teeth, including parts he brushes well and others less, an oral hygienist directly explains you the most effective method.
Once you get the good method, you can thoroughly remove the plaque.

Step.3 in clinic

Removal of tartar(scaling)

Removal of the dental tartar above the gum is called scaling. Since the plaque is strongly fixed, persistent and cannot be easily removed, we first use ultrasonic waves and dedicated instruments on the visible areas to finely remove the tartar.

Step.4 in clinic

Second examination of periodontal pocket and bleeding

We check the amelioration of the periodontitis through a second examination of the pockets following the recent scaling and improvement of tooth brushing, and check the presence of high pathogenic tartar within the deeper portions of the pockets.

Step.5 in clinic

Removal of conchaled tartar(SRP)

Removal of the dental tartar concealed between a tooth and the gum is called SRP (scaling root planning). Since a bio-film having a strong toxin is formed inside the gum, the SRP performed on the tooth destroys the bio-film along with the removal of dental tartar.
Through this intervention, the pocket diminishes.
Early stages of periodontal disease generally recover satisfactorily.

Step.6 in clinic

Second screening

Again, the improvement state is checked and the necessity for ultramodern technology, such as periodontal regenerative medical treatment is evaluated.
If the treatment proves satisfactory, in order to prevent a recurrence, we shift towards a maintenance program (SPT).

Step.7 in clinic

Periodontal surgery

For the purpose of recovery of the alveolar bone and periodontal tissue that were lost in the medium stage of the disease and that the SRP could not save, we try a periodontal regenerative treatment.

※Operation performed after consultation.

Step.8 in clinic


SPT is the abbreviation for Supportive Periodontal Therapy, and consists in the prevention of chronic periodontitis recurrence.
We recommend follow-ups (SPT) once every 1~3 months with the specialized staff who will check on your oral health evolution.

(1)Check whether there are any gum inflammations
(2)Check the gap between teeth and gums
(periodontal pocket check up)
(3)Removal of dental plaque and tartar
(4)Cleaning of pockets

Chronic Periodontitis self check

The method of treatment for periodontitis varies according to the patient's symptoms degrees.
Comparatively, if the disease is at a superficial stage, light medical treatment and adequate daily brushing suffices to cure.

First,let's check on your current condition!

  • My mouth feels sticky when I wake up in the morning
  • I'm bleeding when brushing my teeth or eating hard food
  • My gums feel itchy and sore
  • My gums are red and swollen(healthy gums will look pink and firm)
  • My gums are swollen and bulged(healthy gums are fixed to the teeth)
  • I have bad breath
