Root Canal
Saving Your Natural Tooth with Root Canal Therapy
A root canal is a procedure to save your tooth when a cavity is deep enough to infect the nerve, or when a past treatment fails and an abscess forms at the root. It is one of the most meticulous and important treatments in all of dentistry, and ignoring the need for it can lead to tooth loss.
From the very beginning, our practice has been committed to a higher standard of care, utilizing advanced techniques, a surgical microscope, and rubber dam isolation in all root canal procedures. If you are experiencing severe or increasing tooth pain, we are here to help.
Our Philosophy on Root Canal Therapy
When is Root Canal Therapy Necessary?
Root canal therapy is required when a cavity progresses deep into the tooth and infects the pulp (the inner tissue containing nerves and blood vessels). If severe decay is left untreated, the nerve will die, which can eventually lead to the need for an extraction. The purpose of a root canal is to prevent bacteria from spreading from the infected root into the jawbone, greatly increasing the chances of saving the tooth.
Benefits of Root Canal Therapy
- Saves Your Natural Tooth
- Relieves Pain and Swelling
- Maintains a Natural Bite and Appearance
The greatest benefit of root canal therapy is saving your own tooth. By removing the infected pulp and blood vessels and restoring the tooth’s function, we can significantly reduce the risk of extraction. After the procedure, placing a restoration like a ceramic crown allows us to fully recover your chewing function.
Our Perspective on Root Canal Treatment
Root canal therapy is a vital treatment, yet it is significantly undervalued by Japan’s health insurance system. This has led to a growing trend where it is offered as a private, self-funded procedure, a shift that is widely discussed within the dental community.
We believe high-quality care for a painful tooth should not be a financial burden. That’s why, unlike the growing trend of private-pay root canals, we are committed to providing this essential treatment under your national health insurance plan. (Certain advanced materials may incur extra costs.)
Our goal is to help you invest in your long-term health. We feel it’s a better use of your resources to strengthen teeth, improve your overall oral balance, or prevent future problems, than to spend a fortune on one tooth’s root canal. We’ll work with you to find the best plan for your life.
What Happens When a Cavity Becomes Severe?
- Sharp, throbbing pain that requires painkillers.
- Sensitivity to hot or cold foods and drinks.
- A noticeable increase in bad breath.
- Visible facial swelling.
- Worsening pain with increased blood circulation, such as after drinking alcohol or exercising.
Symptoms like these suggest a deep cavity near the nerve, which is more serious than the visible size of the hole may indicate. Be aware that even a small opening can lead to an infected nerve (C3), so these symptoms should never be ignored.
Our Root Canal Therapy
Enhanced Precision with Microscope Magnification
マイクロスコープとは肉眼の数十倍まで拡大できる精密医療機器です。
根管自体が非常に複雑な構造であり、その正確な情報の把握とともに、虫歯の取り残しや必要以上の歯の切削をしないためにも、拡大視野で確認すること成功率を向上させ、精密治療を実現します。
そのため、当院では全ての根管治療の症例にてマイクロスコープを使用しています。
Dental Dam: Ensuring a Safe and Successful Treatment
For root canals, we use a dental dam (a rubber sheet) to isolate the tooth. This is crucial for preventing re-infection from bacteria in your saliva, ensuring a successful outcome.
The dam also keeps you safe by preventing small materials from being swallowed and helps us create a stronger, more durable restoration by keeping the tooth perfectly dry.
Advanced Root Canal Treatment Covered by Your Insurance
We provide advanced, private-level root canal treatments under your standard Japanese Health Insurance.
Our goal is to make this essential treatment affordable for you. This frees up your budget for higher-quality, non-insured options like ceramic crowns, giving you better choices for your overall dental health.
Let us help you protect your teeth for years to come. Contact us for a consultation.

Proactive Care for Lasting Dental Health
For a root canal to be successful long-term, it is crucial to thoroughly disinfect the canal, seal it completely, and prevent new decay from forming around the tooth afterward.
We believe preventive care is an essential part of everyone’s health routine. Our team works with each patient to propose a personalized oral hygiene plan to help you maintain a healthy smile for life.
