For patients seeking urgent dental care

Walk-in patients seeking dental treatment in an emergency are always welcome. We accept Japanese National Health Insurance (Hokensho or Individual Number Card).

Most dental problems have one thing in common: they get more serious the longer you leave them alone. The best way to deal with a possible dental problem is to address it right away. The faster you have a dentist treat your problem professionally, the lower the chance it becomes something very serious. That’s what seeking urgent dental care is all about.

I can help you. You will be fine!
