Located on the 3rd floor of Comodi Iida Namaizumi, Keita Dental Clinic was established in 2000 by Director Keita Watanabe, a Meikai University School of Dentistry graduate. The clinic provides dental care centered on whitening, implants, autotransplantation, and laser treatment. Patient needs are prioritized with treatments designed to minimize physical, mental, and economic burden, following a four-step process: consultation, examination and treatment planning, treatment, and completion with regular checkups. For whitening without tooth reduction, both office and home methods are available, with home whitening recommended for maintaining whiteness. English support, credit/debit cards, electronic payments, parking, and barrier-free access are available. The clinic is affiliated with the Japan Dental Association, Tokyo Dental Association, Japanese Academy of Oral Implantology, and Japan Society for Laser Dentistry, providing specialized treatment based on expertise.
