Azuma Dental Clinic, located in Sennincho, Hachioji City, Tokyo, is a dental clinic equipped with a parking lot that offers English support. They provide comprehensive dental treatment focused on preventing the recurrence of cavities and gum disease, following a three-step process: first examining the entire mouth to comprehensively identify issues, then performing precise treatment using microscopes, and finally preventing recurrence through regular check-ups. Through microscopic dentistry, they achieve minimally invasive treatment that removes as little tooth structure as possible, contributing to reduced recurrence rates. Preventive dentistry and dental examinations are also well-provided, with efforts to prevent recurrence through regular cleaning and minimize treatment through early detection. Their approach to minimizing patient discomfort is also notable, using computer-controlled injection needles after applying topical anesthesia to keep pain to a minimum. The clinic features a warm atmosphere with indirect lighting, as well as a dedicated children's area equipped with videos, books, and toys. Instruments that contact the mouth and those used in treatment are sterilized at the virus level using high-pressure sterilizers that meet the latest European standards.
