Oya Orthodontic Dental Clinic, located in the Daki Building in Befu-cho, Kakogawa City, Hyogo Prefecture, is a dental clinic specializing in orthodontics. The clinic's major feature is its provision of lingual orthodontic treatment (lingual bracket orthodontics). This treatment method involves attaching orthodontic appliances to the back of the teeth, allowing patients to improve their teeth alignment and bite without being noticed by others. It is a viable option for those in customer service or professions requiring public appearances who are hesitant about visible front-side appliances. While a half-lingual approach (applying lingual treatment only to upper teeth) is available, the clinic recommends full lingual orthodontics for both upper and lower teeth to maximize the benefits of this method. Additionally, there is an advantage for those concerned about protruding teeth, as front teeth can be retracted more easily. On the other hand, some discomfort and difficulty eating may be experienced initially, but patients typically adapt within 1-2 months. Clinic hours are from 11:00 to 13:30 and 15:00 to 20:00, allowing visits during evening hours. Note that orthodontic treatment is a self-pay procedure not covered by public health insurance, with a typical treatment period of approximately 3-5 years. English language support is available, making it accessible for those who require communication in languages other than Japanese.
