Located in Moriguchi City, Osaka, Arai Dental Clinic, operated by the Medical Corporation Arai, is a dental facility known as a "painless dentist." Situated in a residential area along Keihan Main Street, the clinic is equipped with barrier-free facilities. In addition to general dentistry, it offers a wide range of specialties including pediatric dentistry, orthodontics, aesthetic dentistry, and whitening, with English-speaking services available. In treatment, the clinic uses large screens in front of patients to display intraoral photos and X-rays, explaining procedures to alleviate anxiety about unknown treatments. For cavities, periodontal disease, and dentures, the clinic protects patients' dental health using minimally invasive methods that preserve tooth nerves whenever possible. The clinic also focuses on pediatric dentistry and pediatric orthodontics, providing preventive treatments such as brushing guidance and fluoride application, as well as occlusal development treatments to prevent poor tooth alignment and bite during growth. In orthodontics, primarily partial corrections are performed, with clear aligner systems like Invisalign GO also available. Aesthetic dentistry services include home whitening, office whitening, and walking bleach treatments, as well as restorative treatments using laminate veneers and all-ceramics. Since July 2024, a new reservation system has been introduced, enabling app notifications and online booking. The clinic is closed on Thursdays, Sundays, and holidays.
