Okada Dental Clinic, located in Higashisue, Ube City, Yamaguchi Prefecture, is a clinic specializing in dental care. In addition to general dentistry, the clinic offers a wide range of services including orthodontic treatment and teeth whitening. For orthodontic treatment, the approach is clearly differentiated between the mixed dentition period (approximately ages 6–10), when both primary and permanent teeth are present, and the permanent dentition period (middle school age and older). During the mixed dentition period, plate-type appliances are used to promote jaw development through orthopedic treatment, while during the permanent dentition period, full orthodontic treatment using multi-bracket (fixed wire-type) appliances is available. Teeth whitening is provided via a home whitening method, in which patients use custom-fitted mouthguards to whiten their teeth at home. The clinic is open from 9:00 AM to 8:00 PM, with evening appointment slots available, making it convenient for those who find it difficult to visit during daytime hours. With English-speaking staff, as well as parking facilities and barrier-free access, the clinic is welcoming to patients from a wide range of backgrounds.
