Located in Ojin, Hiratsuka City, Kanagawa Prefecture, Masui Dental Clinic is a dental facility that supports oral health for people of all ages, from young children to the elderly. The clinic places the greatest emphasis on prevention. With a philosophy focused on prevention rather than treatment, it recommends regular dental cleanings in addition to daily brushing. Proper care during childhood helps develop tooth enamel that is less prone to cavities, and by practicing thorough prevention from the 20s and 30s, people can retain their precious teeth at any age with high probability. Based on the concept that reducing cavity-causing bacteria through proper knowledge and correct toothbrushing can prevent cavities with high probability, the clinic provides oral cleaning services. Preventive dental treatments are performed after regular treatments are completed or concurrently with regular treatments, supporting the retention of healthy teeth for as long as possible. In terms of facilities, the clinic has a parking lot and is barrier-free accessible. The clinic supports English and other languages, and is closed on Thursdays, Sundays, and holidays.
