Toyosu IHI Building Dental Clinic is located in Toyosu, Koto Ward, Tokyo, in front of Shibaura Institute of Technology. As a dental clinic capable of providing English-language services, it is equipped with a parking lot and barrier-free facilities. The clinic has introduced the CEREC system using the latest CAD/CAM technology, enabling treatments that traditionally took about a week to be completed on the same day at the shortest. It is a cost-effective system that uses aesthetically excellent ceramic materials without concerns about metal allergies. For whitening, the clinic uses a light that can irradiate all visible teeth at once, allowing treatment to be completed in a short period with quick results. The clinic offers general dentistry services, including preventive dentistry, periodontal disease treatment, and aesthetic dentistry. It is said that four out of five people over 40 suffer from periodontal disease, which is the primary cause of tooth loss and one of the two major dental diseases alongside tooth decay. Given this background, the clinic comprehensively addresses the two major dental diseases—cavities and periodontal disease—from prevention to treatment. The clinic's operating hours are 9:30 AM to 1:00 PM and 2:30 PM to 7:00 PM on weekdays, with the clinic closed on weekends and holidays. Dr. Hiroyuki Takikawa, the director, values three principles: careful and minimally invasive dental treatment with minimal pain, dental treatment that makes comprehensive and multifaceted judgments, and dental treatment that considers and worries alongside the patient. When considering the long term, tooth extraction or root canal treatment may not always be the best choice, so rather than simply removing pain, the clinic considers the optimal method to maintain teeth for as long as possible. Before starting treatment, the dentist makes sure to explain their professional opinion in an understandable manner, hoping that patients will understand their own oral health situation.
