Takenaka Dental Clinic is a dental and orthodontic clinic located in Fuchu-cho, Aki District, Hiroshima Prefecture, focusing on preventive dentistry. Since teeth and periodontal tissues do not heal naturally, the clinic emphasizes the prevention of tooth decay and periodontal disease. Business hours are split into two sessions: 09:00-12:30 and 14:30-19:00, with Sundays and holidays as closed days. The treatment process includes addressing symptoms, examination and diagnosis through X-rays and gum examinations, and treatment planning through counseling using monitors. The clinic is characterized by pain management through electric anesthesia devices and surface anesthesia, as well as flexible responses that allow for ongoing adjustments to treatment plans. In terms of facility equipment, the clinic has introduced electric injectors, extraoral vacuums, CT, microscopes, and CO2 lasers, and also provides nitrous oxide anesthesia. These facilities are utilized to improve treatment precision and create a treatment environment that reduces anxiety and fear. After treatment completion, regular maintenance by dental hygienists is provided to maintain oral health. The clinic offers parking, barrier-free accessibility, and English language support. The director, who holds a PhD in Dentistry, supports the oral health of the local community through daily clinical practice.
