Located in Ayase, Adachi Ward, Tokyo, Arai Dental Clinic is a dental practice rooted in the local community. The clinic's core philosophy centers on 'breaking free from the cycle of re-treatment.' The chain of repeated treatments—where once-treated teeth become painful again, or teeth with removed nerves fracture and require extraction—has been a longstanding challenge in Japanese dental care. Arai Dental Clinic places this awareness at the heart of its treatment approach, working to achieve treatment that prevents the repetition of re-treatment. The director has continuously confronted this issue throughout his career as a dentist, and this commitment is consistently reflected in the clinic's practice. Clinic hours are 10:00 AM to 1:00 PM and 2:00 PM to 6:00 PM, closed on Wednesdays, Sundays, national holidays, and during the New Year period. With parking available, the clinic provides an accessible environment even for patients who find public transportation difficult. The clinic's emphasis on fundamental treatment to maintain long-term dental health is its defining characteristic.
