Located in Miyawakicho, Takamatsu City, Kagawa Prefecture, Ishii Dental Clinic is a dental clinic that meets the strict facility standards set by the Ministry of Health, Labour and Welfare, providing periodontal treatment, preventive dentistry, and whitening. The clinic practices treatments with minimal pain—for instance, to reduce injection pain, a topical anesthetic applied to the gums is administered first. For patients with strong fear or anxiety about dental treatment, treatment using nitrous oxide inhalation sedation is also available. Through these innovations, the clinic strives to create an environment where even those who dislike dentists can visit comfortably. The clinic performs periodontal internal medicine treatment (*), which aims to improve periodontal disease with oral medication, and has a microscope on-site to check the number and types of bacteria in the mouth. Pre-examinations using this microscope identify the types and quantities of periodontal bacteria, allowing treatment to proceed with more effective medications and methods. Furthermore, medication reduces periodontal bacteria to suppress gum inflammation and alleviates pain during tartar removal procedures. Among the dental hygienists, some members hold the Whitening Coordinator qualification certified by the Japanese Academy of Esthetic Dentistry. These qualified personnel handle counseling and treatments. The clinic emphasizes communication in its medical care; during counseling, not only do they explain verbally, but they also provide clear and careful explanations using X-ray images and other aids. While understanding the condition of the mouth, they also grasp the patient's life background and preferences, aiming to offer suggestions that lead to the best possible treatment. Services are also provided in English.
