Dentist or Salesmen?

Time has certainly change, or time has make my opinion towards dentist change.. to the worst. In early 2007 I went to have my teeth cleaned and I was given a clean bill of health, clean bill of teeth...it was in Tennessee and I truly like this dentist. Fast forward 1 year and I went to a different dentist (I have since move to South Carolina) and after the end of the half/pseudo cleaning, I was given a treatment plan, 4 gum treatments and 2 fillings. I didn't go for it because the reason I need gum treatment was because they wouldn't stop jamming x-ray apparatus into my Asian jaw. I can hardly close my mouth and they want me to bite down. Gums were still hurting after 2 days. So after 6 months, and many many cups of coffee and tea later, I went to a different dentist. And this time after a real cleaning I've had had since the first dentist I went to I was satisfied. Until the dentist came in and start checking my teeth sans x-ray (the second dentist didn't fax over the x-ray) and starts to roll call bad teeth, and its almost everyone single one of them. Finally I was given a treatment plan, 8 fillings! Amazing how 6 months can do your teeth or is it something that I need to investigate further, wait 6 more months and go to another dentist? Also, notice how the last 2 dentist in South Carolina loves dispensing treatment plan and its not quick one time treatment. The plans usually requires you to make at least 4 more visits. Don't worry, there are at least 4 pages of dentist listing in the Yellow Pages until my teeth all rot and falls off.
