Dentistry & Oral Surgery


NTT Dental & Oral Surgery provides medical treatment of tumors and cysts formed on the oral mucous membrane and a jaw, as well as dental infection and trauma. We also provide the dental extraction of wisdom teeth (the impacted teeth) that was difficult to perform at a general dental clinic.
We specialize in the treatment of tumors, both benign and malignant, treatment-resistant osteomyelitis (chronic infection of teeth) and submandibular gland sialolithiasis (salivary stones).
In the treatment of oral cancer, we set a goal for the patients to get back to normal life through complete cure of the cancer. We aim to restore function not only by the surgical resections, but also with a combination of reconstructive surgery, radiation therapy, and medication therapy. We dedicate ourselves to improve the treatment outcome for our cancer patients and we treated 95 cases of the oral cancers in total from January 1, 2017 through December 31, 2020 alone.


The oral cavity (structures from mouth to a throat) plays vital roles in every day functions such as biting, swallowing and speaking. We therefore strive to select the best treatment for each patient, while preserving the quality of life (QOL) as much as possible.

3.Our Strengths

We Value Teamwork

In order to provide high quality dental treatments, we collaborate with other departments and professionals. At the dental outpatient, we provide the medical treatment with dental hygienists, nurses, and dental technicians. For the treatment of oral cancer, we hold regular discussions with the Otorhinolaryngology・Head & Neck Surgery, Radiologists, Oncologists, Rehabilitation teams and Surgeons.

Minimizing Pain and Anxiety for Tooth Extraction Surgery

We understand that the removal of impacted teeth or wisdom teeth buried deep inside the bones or gums can cause tremendous anxiety. Our surgeons may use intravenous sedation or general anesthetics in some cases, while being safely monitored in hospital, thus minimizing pain and anxiety of the surgery.

Treatment of Treatment-Resistant Osteomyelitis

Osteonecrosis of the jaw especially due to the medication (bone resorption inhibitor such as bisphosphonates, and denosumab) is increasingly becoming more common and we are working on the prevention and treatment of this condition. We are currently conducting a clinical research for the treatment of refractory chronic osteomyelitis with diffuse osteosclerosis.

Message for Our Patients

When you wish to consult our doctors, please bring a referral from your primary care dentist as much as possible. When we are finished with the treatment, we may ask your primary care dentist to continue the follow up treatments.
Please note that we do not provide some of the general dental treatments such as cavities and dentures.
