Hirai Dental Clinic is a community-based dental practice located in Wake-cho, Wake-gun, Okayama Prefecture. The clinic places a strong emphasis on preventive dentistry, grounded in the belief that oral health is closely connected to overall systemic health. Particular attention is given to brushing instruction, with the clinic advocating a unique technique known as the toothpick method, which involves inserting bristle tips between the teeth to help prevent cavities and periodontal disease. In addition to general treatments such as cavity care and periodontal therapy, the clinic offers a wide range of services including root canal treatment and dentures. Denture options include insurance-covered resin base dentures as well as private-pay metal base dentures made from cobalt or titanium, and non-clasp dentures with no visible metal clasps. A CT X-ray system was introduced in 2013, enabling more precise diagnosis. In the field of orthodontics, both wire braces and plate appliances are available, with treatment plans tailored to each patient's age and condition. For pediatric patients, the clinic takes care to minimize the use of restraints and strives to create a reassuring environment, such as showing children their mouth using a mirror during treatment. English-language consultations are available, and parking is provided on-site. Office hours are from 8:30 a.m. to 6:00 p.m., with the clinic closed on Thursdays, Sundays, and public holidays.
