Located in Nakagao-cho, Kita-ku, Sakai City, Osaka Prefecture, "Kei Dental & Aesthetic Dermatology" is a medical facility offering both dental and aesthetic dermatology services. Director Kei Higashizawa, drawing from his own experience with dental phobia, has pursued "painless treatment" with particular attention to three aspects of anesthesia injections: "where to administer anesthesia," "how to insert the needle," and "the initial depth of insertion," developing techniques to minimize pain to the utmost limit. A distinctive feature of the clinic's treatment policy is providing thorough explanations not only for teeth currently causing pain but also for teeth and gum conditions that may become problematic in the future, with emphasis on early detection of issues that are difficult to self-detect, such as cavities beneath fillings and crowns, and lesions at the root tips. Consultation hours extend until 9:30 PM on weekdays (Monday, Wednesday, Thursday), making it convenient for after-work visits. Additionally, the clinic is open on Saturdays, Sundays, and holidays, providing accessible healthcare for those who find it difficult to visit on weekdays. The facility features barrier-free design allowing smooth movement with strollers, and includes a kids' room, making it comfortable for families with small children. English consultation is available, and the clinic accepts credit cards, debit cards, and electronic payments, offering various payment options for convenience. Parking is also available, accommodating patients who visit by car.
