Looking for a Dentist and Medical Doctor Yokohama (Tokyo)

Hello,

I live in Yamate Yokohama not far from the centre of Yokohama (Yokohama Station). I need a good dentist, English speaking and a general medical doctor for health care. I went to the Bluff Clinic in Yamate but was not happy with the service. I've been a bit shocked at some dental places I've gone as they were a bit unhygienic so would prefer one that is. Thanks.
