Located just a 1-minute walk from Shinjuku Station, Igarashi Dental Office is a comprehensive dental clinic situated on the 9th floor of the Shinjuku Mitsuba Building. The clinic offers a wide range of treatments, from general cavity treatment and periodontal therapy to preventive care, implants, and clear aligner orthodontics (Invisalign). One of the clinic's key features is that both the director and dental hygienists perform precision treatments using high-magnification loupes and microscopes. Additionally, the clinic has introduced advanced medical equipment such as 3D intraoral scanners and dental CT, enabling accurate diagnosis and treatment planning without relying solely on experience or intuition. For Invisalign treatment, the director holds the prestigious Invisalign Diamond Provider status, allowing the clinic to handle cases that other clinics may find difficult. The clinic also emphasizes infection control, implementing thorough hygiene management based on standard precautions, introducing fully automated cleaning systems and European-standard Class B sterilizers, and utilizing disposable instruments to create a safe treatment environment. Consultations are available until 7 PM on weekdays and on Saturdays, with credit card and electronic payment options accepted.
