① Precision Treatment & Prevention — Preserving Teeth and Nerves. Microscopes Installed in All Treatment Rooms.
Not only our dentists but also our dental hygienists perform treatment using microscopes. With enhanced visibility, we minimize unnecessary drilling, avoid removing nerves, and reduce the need for extractions. Over 200 patients visit us monthly, yet we perform dentures only about once a year and implants once a month or less. Our photo and video explanations also help patients clearly understand their treatment.

• Discoloration over time.
[Rubber Dam Partial Pulpotomy]

② Comprehensive Preventive Dentistry — A “Dedicated Dental Hygienist System” to Prevent Oral Disease.
Many people visit the dentist only after symptoms appear, such as tooth pain or bleeding gums. However, cavities and periodontal disease are irreversible once tissue is lost. This is why our clinic focuses on prevention, not just treatment. To maintain your lifelong oral health, a dedicated hygienist thoroughly supports your care.
Why do we insist on assigning each patient a dedicated hygienist?
-
1. Early Detection Through Continuity
Seeing the same hygienist each visit allows even subtle changes—gum color, tooth surface, brushing habits—to be noticed early.
-
2. Personalized Prevention Plans
Your oral condition, saliva quality, lifestyle, and health background are all understood. This enables tailored, evidence-based prevention—not generic advice.
-
3. A Relationship That Encourages Communication
Patients feel more comfortable asking questions or voicing concerns when trust is established. We value communication to help you achieve the best oral health outcomes.
-
4. Motivation Through Partnership
Prevention requires both professional care at the clinic and self-care at home. Your hygienist supports and encourages you to maintain healthy habits with confidence.
③ Experienced Specialists in Various Fields
Our clinic has specialists in endodontics, dentures, implants, and restorative dentistry. This allows us to provide advanced, specialized care entirely within our clinic.
→ Meet Our Staff
④ Minimizing Pain & Stress During Treatment
We use electric anesthesia devices, ultra-fine needles, and topical anesthetic patches. These techniques significantly reduce pain during injection, creating a more comfortable experience.
⑤ Direct Access from Tokyo & Otemachi Stations
Convenient location within 1–5 minutes on foot. You can visit the clinic comfortably without getting wet on rainy days.

Director
Yuta Ohara
【Preventive Dentistry × Precision Treatment】
I am Dr. Ohara from Kuribayashi Dental Clinic Marunouchi.
It is said that the same tooth can only be treated 4–5 times in a lifetime.
Silver fillings last on average about 5–10 years. If your first treatment is done in your 20s, by your 50s you may already have undergone more than five treatments on the same tooth, significantly increasing the risk of tooth loss.
In fact, the average number of remaining teeth in Japan decreases starting in the 50s, and from there, people tend to lose one tooth every 3–4 years.
We are committed to preventing dental problems before they occur and providing precise treatments that minimize the recurrence of decay.
If you wish to keep your natural teeth for life, please feel free to consult us.
We look forward to welcoming you.
