Doi Dental Clinic, conveniently located in Chuo Ward, Sapporo, just a 2-minute walk from JR Koen Station, sits directly in front of Aeon Shopping Center. Dr. Masato Doi, the director, doesn't view the oral cavity as an isolated organ but practices "medical dentistry," considering its connection with the digestive and respiratory systems and linking oral care with overall health. The clinic offers a wide range of services, from general cavity and periodontal disease treatment to orthodontics, implants, cosmetic dentistry, and whitening. They specialize in safe implant placement using guide surgery and ceramic treatments with proven high survival rates. Treatment rooms are private, with a focus on informed consent and careful explanations in a comfortable setting. The clinic has also introduced the latest equipment, including dental CT, pursuing precise diagnosis and minimally invasive treatment. Operating until 8 PM on weekdays, the clinic accommodates those who find daytime visits difficult. Additional conveniences include English-speaking staff, credit card and electronic payment options, and on-site parking.
