I recently moved to Porland and had to find a new dentist. A friend recommended Dr. Campbell. Over the years I've had cavities filled by other dentists. While they did an ok job of minimizing pain, Dr. Campbell is the first dentist who actually achieved painless work. Topical numbing stuff was applied to my gums before the actual novacaine injection was done so i never even felt the injection! After the novacaine wore off, I had no soreness like in the past. Clean and professional office/staff. I'll be keeping Dr. Campbell as my dentist.
