Located in Sekido, Tama City, Tokyo, Hayashi Dental Clinic is a dental clinic that provides services in English. The clinic's motto is 'preserve as much as possible, extract as little as possible,' focusing on root canal treatments to save patients' natural teeth. Root canal treatment is a procedure that removes decayed nerves from the root canal, disinfects the interior, and fills it with medication, with the goal of preserving the tooth. At this clinic, rubber dam isolation prevents saliva and bacteria from entering the root canal, and after nerve removal, the interior is cleaned and sterilized to achieve a germ-free state. In terms of equipment, the clinic has introduced air purifiers with industrial hypochlorous acid humidification, ViralWall, and Class B sterilizers, and after patients leave, the units are disinfected with electrolyzed water. Through these infection prevention measures and high-precision equipment, a meticulously maintained clinical environment is provided.
