Gassan Dental Clinic, located in Motoasakusa, Taito Ward, Tokyo, is a dental clinic specializing in dental care. Since January 2025, the clinic has acquired the facility standards for 'Enhanced Oral Function Management System (Kokan Kyo),' establishing a comprehensive management system that extends beyond maintaining teeth and oral health to include overall oral functions such as chewing and swallowing. A key feature is its ability to provide specialized support for elderly patients and those requiring systemic health management. For early detection of cavities, the clinic has introduced the laser diagnostic device 'Diagnodent Pen,' which can numerically visualize early-stage cavities that are difficult to detect visually. The examination is painless and completes in seconds, ensuring considerate care for patients with strong dental anxiety and children. The interior was renovated in October 2020, creating a spacious environment with improved ventilation efficiency and consideration for social distancing. The clinic also focuses on creating an environment that eases patient tension, such as playing high-quality BGM through Danish DALI speakers. Home dental care services are available for patients who have difficulty visiting the clinic, providing community-based comprehensive dental care. Credit cards and electronic payments are accepted.
