Dental Care in Japan: Costs With or Without Insurance [2026]

In Japan, dental care is also covered by public health insurance, so treating cavities and gum disease costs little out of pocket. This guide covers what's covered, cost guide, the visit flow, children's dental and multilingual options.

① Counter payment (10–30% by age)

For insured treatment, you pay 10–30% by age/income (20% before school age; 30% from school age to 69; generally 20% at 70–74; generally 10% at 75+). Bring your My Number insurance card or Certificate of Eligibility.

② Insured vs. self-pay treatment

• Insured: treating cavities, extractions, gum-disease treatment, scaling, insured fillings/crowns (silver, resin), insured dentures, etc.
• Self-pay: cosmetic ceramics, whitening, orthodontics (in principle), implants. Prices vary by clinic

③ The visit flow

Dentists usually work by appointment. At the first visit you fill in a form (conditions, medication, allergies) and show your insurance. Treatment often takes several visits, not one.

④ Cost guide (insured, 30% co-payment)

• First visit (with exam): roughly 3,000–4,000 yen
• A small cavity: ~1,500–3,000 yen / heavier work (root canal): a few thousand to ~20,000 yen over several visits
• Insured checkup/cleaning: ~1,000–2,500 yen per visit

* These are estimates, not fixed prices. Self-pay treatment is fully out of pocket.

⑤ Checkups & cleaning

Cleaning/scaling done as part of treating gum disease is covered. Cleaning purely for prevention on healthy teeth, and whitening, are generally self-pay.

⑥ Children's dental

Many municipalities include a dental check at the 18-month and 3-year health checks and offer fluoride application free or cheaply. Child medical subsidies may reduce or waive the co-payment for insured dental treatment (coverage varies by municipality).
