Nagao Dental Clinic, located in Shibadaimon, Minato Ward, Tokyo, has been providing dental care in the Daimon and Hamamatsucho area for over 20 years. The clinic's philosophy centers on "preserving natural teeth whenever possible," avoiding unnecessary extractions and helping patients maintain their own teeth for as long as possible. This approach stems from years of experience witnessing how tooth loss can diminish one's enjoyment of meals and conversation. The clinic offers appointments until 9 PM on weekdays, making it accessible for working patients who find it difficult to visit during daytime hours. Additionally, the clinic provides treatment for snoring and sleep apnea, collaborating with nearby ENT specialists to create night guards (mouthguards) after diagnosis—comprehensive support that extends beyond traditional dentistry. The clinic also accommodates English-speaking patients, making it a suitable choice for those who prefer treatment in a language other than Japanese.
