Hi freshstart,
There are several good dentists in town. I personally receomend Family Dental Clinic off C ring, the there is Dr Sarah's clinic which is good too. Some others might give you different names too. All good ones charge approximately the same. Dental work does not come cheap, anwhere in the world. If you get a cheap dentist, you will get cheap work done and pay for it in the long run.
