Tomonaga Dental Clinic, located in Tairahara, Kashiwara City, Osaka Prefecture, is a highly accessible dental clinic equipped with English language support, parking, and barrier-free facilities. In addition to providing orthodontic treatment by inviting specialist orthodontists from outside, the clinic employs many nationally licensed dental hygienists who perform treatments with thorough explanations that satisfy patients. The treatment philosophy emphasizes "valuing patients' irreplaceable teeth" and explores methods to preserve teeth as much as possible, characterized by a cautious approach toward tooth extraction. Furthermore, beyond treating cavities and periodontal disease, the clinic focuses strongly on preventive dentistry, with a system in place to understand each patient's oral hygiene status and conduct regular check-ups. Regarding COVID-19 infection control, the clinic has installed large mesh screens at the entrance to ensure adequate ventilation, thoroughly implements standard precautions such as masks, gloves, and disposable aprons, and strives to prevent nosocomial infections through operating medical air purifiers and conducting patient temperature checks.
