Last weekend, I had a dental emergency. My level of Japanese is just enough to set an appointment, but definitely not enough to understand any medical procedure (I had to google what "gums" were in Japanese).
Hayakawa Dental Clinic is a rather big clinic with 3 attending dentists and a lot of dental hygienists and assistants. Initially, I had an appointment for a week later because the clinic is a little busy. But the pain became unbearable a few days after I set the appointment. I asked a friend to call them and tell them that I had an emergency. So I came just before clinic hours started just in case they could accommodate me. The staff were patient, treated me as if I had an appointment, and one of the dentists was able to accommodate me. I had an X-ray taken, my tooth cleaned, and my situation explained to me. The dentist I saw could understand English, and could also speak basic English. The assistants spoke Japanese, but were very gentle and used signs to explain whatever I couldn't catch.
I am very grateful !
