Sakai Dental Clinic is a dental clinic located in Takakuradai, Minami-ku, Sakai City, Osaka Prefecture, featuring English-speaking staff and an on-site parking lot. The clinic emphasizes gentle treatments that avoid unnecessary tooth extractions and drilling whenever possible. Infection prevention measures include thorough temperature checks, alcohol-based hand sanitizing, proper ventilation, and mandatory face mask wearing, all aimed at creating a comfortable environment. Regarding clinical care, the clinic focuses on the importance of periodontal disease, explaining symptoms such as itchy teeth, redness and swelling at the gum line, and bleeding during brushing. Periodontal disease, considered a modern condition affecting approximately 85% of adults, is a major cause of tooth loss and can lead to systemic health risks. The clinic practices the "8020 Movement"—which encourages keeping at least 20 of one's own teeth at age 80—as an early "7020 Movement," with over 300 current patients meeting the 8020 standard. This initiative aims not merely to preserve more teeth, but to ensure and improve quality of life. By emphasizing prevention of cavities and periodontal disease, the clinic supports patients as partners in protecting and nurturing lifelong oral health.
