Your treatment options
Removing stain or calculus is useful, but a maintenance visit also checks for changes that are easy to miss at home.

New lesions, exposed roots, dry mouth, diet and fluoride use can affect the preventive plan and recall interval.
02
Pocket measurements, bleeding and access around crowns, implants or orthodontic appliances influence the type of cleaning needed.
03
We show you the areas that are being missed and recommend brushes or interdental tools that fit your mouth and daily routine.
Treatment options
Insured care and self-pay cleaning have different indications and contents. We explain which applies before treatment.
When a clinical diagnosis and your insurance eligibility meet Japanese requirements, examination and necessary cleaning may be covered. Your out-of-pocket amount depends on the care provided.
A self-pay full-mouth enamel-apatite coating course without added options.
¥13,200 including tax.
Longer self-pay courses include additional options selected from the clinic menu.
¥22,000 for 60 minutes or ¥33,000 for 90 minutes.
Cleaning removes surface deposits and stain. Whitening is a separate self-pay treatment intended to change the colour of natural teeth.
After your examination, we will explain the recommended option, total fee and expected schedule before you decide.

Examination and treatment planning
Orthodontics, implants, new restorations, pregnancy, medication and changes in dexterity can alter cleaning needs. We review the plan whenever your oral health or circumstances change.
What to expect
Step 1
The teeth, gums, restorations, implants and oral tissues are examined according to your needs.
Step 2
Plaque, calculus and surface stain are removed using the method appropriate for the findings and chosen course.
Step 3
We show the sites that need attention and adjust brushes, interdental cleaning or fluoride advice.
Step 4
The interval is based on current risk and treatment history and can change as the mouth becomes more or less stable.
Treatment details
The figures below are general guides. After examining you, we will provide a written estimate and expected schedule.
Amounts include tax. Self-pay care is not covered by Japanese public health insurance. When insured care may apply, eligibility and cost depend on the diagnosis and your insurance status.
