 In hopes to ease your dental fear, anxiety or stress as much as possible, we took the time to create the interior design that can help you feel comfortable the moment you open the door to our clinic.

 Our treatment rooms are designed to protect your privacy and comfort. You will have your own room where you can receive your treatment in a quiet, relaxing environment. Please feel free to visit us.

 English-speaking dentist and dental hygienists provide a wide range of dental services, including fillings, crowns, root canal treatment and children's dentistry.

 Dr. Umezu has specialized training in advanced cases involving implants and prosthodontics (crowns and bridges). All treatment is done based on American methods. When necessary, referrals can be made to specialists. Our office can fill out all foreign dental insurance.
