01
Is the pulp the source?
Cold, biting and percussion tests, examination and appropriate imaging help distinguish reversible irritation from infection that needs root-canal treatment.

Root Canal Treatment in Saitama
If a tooth is painful, swollen or sensitive for a long time, root canal treatment may be needed to treat inflammation or infection inside the tooth. We first identify the source of the symptoms and assess whether the tooth can be restored, then explain insured and self-pay options in English.
The booking form is in Japanese. If you need help choosing a service or arranging English support, please message us on LINE.

Your treatment options
Finding the cause of tooth pain
A cracked tooth, gum problem, sinus-related symptom or another tooth can feel similar. Diagnosis precedes opening the tooth.
02
Can the tooth be restored afterward?
A tooth may not be retainable when cracks, decay or loss of tooth structure extend too far. The final restoration is considered before root-canal treatment begins.
03
Is this initial treatment or retreatment?
Previously treated teeth can have complex anatomy, blocked canals or existing restorations. Retreatment has different difficulty, fees and limits.
Treatment options
Root canal treatment and other options
The clinic offers insured treatment and self-pay precision treatment, with differences explained before you choose.
Initial root canal treatment
The infected or inflamed tissue is removed, the canals are cleaned and disinfected, and the space is filled.
Self-pay root canal fees: front tooth ¥55,000, premolar ¥77,000, molar ¥110,000. The core and final restoration are separate.
Root canal retreatment
Existing root filling material is removed and the canals are treated again when retreatment is considered feasible.
Self-pay retreatment ¥132,000.
Restoration after treatment
A core and filling or crown may be needed to protect and restore the tooth. This is a separate treatment stage and is quoted according to the selected material.
Extraction and replacement options
When the tooth cannot be predictably restored, extraction and later replacement with a bridge, denture or implant may be discussed.
After your examination, we will explain the recommended option, total fee and expected schedule before you decide.
Examination and treatment planning
What we check before starting treatment
A microscope can improve visibility during treatment, while X-rays or CT can help assess anatomy and infection. We also check whether enough healthy tooth structure remains for the tooth to be rebuilt after treatment.
- Pain history, swelling, biting symptoms and previous treatment
- Pulp and percussion testing when applicable
- Decay, cracks, existing crowns and remaining tooth structure
- Root anatomy and surrounding bone on appropriate imaging
- Need for isolation, core build-up and a final restoration
What to expect
From diagnosis to the final restoration
Step 1
Diagnosis and whether the tooth can be saved
We identify the likely source, review imaging and assess whether the tooth can be rebuilt after treatment.
Step 2
Cleaning and disinfection
The tooth is isolated to reduce contamination, and the canals are located, cleaned and disinfected.
Step 3
Root filling
The cleaned canal space is sealed. The number of visits depends on anatomy, infection and symptoms.
Step 4
Core and final restoration
The tooth is rebuilt and protected with the restoration required for its remaining structure and bite.
Treatment details
Fees, treatment time and possible risks
The figures below are general guides. After examining you, we will provide a written estimate and expected schedule.
- Treatment
- Cleaning, disinfection and filling of the root-canal space to retain a tooth affected by pulp inflammation or infection. A core and final restoration may be required afterward.
- Fees
- Japanese insurance may apply depending on diagnosis and eligibility. Self-pay initial root canal treatment is ¥55,000 for a front tooth, ¥77,000 for a premolar and ¥110,000 for a molar; retreatment is ¥132,000. A complete example using initial treatment, a ¥16,500 fibre-post core and a basic zirconia crown with its fitting fee is ¥205,700–¥260,700, including tax. The actual total depends on the tooth and final restoration.
- Time and visits
- One to several visits is a guide. Anatomy, infection, symptoms and retreatment can increase the number of appointments. The final restoration requires additional visits.
- Possible risks and side effects
- Temporary pain or tenderness can occur after treatment. Complex anatomy or persistent infection can lead to incomplete healing, further treatment or extraction. A root-treated tooth is more susceptible to fracture and may need protective restoration and follow-up.
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.

Frequently asked questions
Questions about root canal treatment
Does severe tooth pain always mean I need a root canal?
No. Examination and tests are needed because cracks, gum inflammation, sinus symptoms and other teeth can produce similar pain.
Why do I need a crown after a root canal?
Some root-treated teeth have lost substantial structure and are more susceptible to fracture. The required restoration depends on the tooth and how much sound structure remains.
Can a previously treated tooth be treated again?
Sometimes. Retreatment feasibility depends on the tooth, root anatomy, existing restoration, infection and whether the tooth can be rebuilt.
Can I stop when the pain is gone?
No. A temporary reduction in pain does not mean treatment is complete. Delaying the remaining stages can allow contamination or fracture.
Is microscope-assisted treatment self-pay?
The available insured and self-pay options depend on the treatment plan. Differences in procedure and cost are explained before treatment.
