Narita Dental Clinic, located in Kamikitazawa, Setagaya-ku, Tokyo, is a dental practice founded on the philosophy that 'in this era of people living to 90, patients should be able to eat with their own teeth even at age 90.' Director Yasuyuki Narita graduated from the Nihon University School of Dentistry at Niigata, and after engaging in clinical work, research, and education in oral surgery, gained clinical experience at the NIH and in countries including India and China before becoming the third-generation director. A key feature of the clinic is maintenance care provided by dental hygienists, who are oral care professionals. Dentists always check the patient's oral condition after treatment, ensuring high-quality continuous care. In terms of infection control, the clinic has introduced multiple sterilization devices and maintains a safe treatment environment with thorough infection prevention measures. Additionally, the clinic utilizes dental CT and specialized systems to carefully explain oral conditions and treatment plans in an easy-to-understand manner based on examination results and images, which is another strength of the clinic. The clinic offers general dentistry as well as dental implant treatment, periodontal surgery, and treatment for temporomandibular joint disorders.
