It's awful isn't...am I'm hardly scared of anything.
I just went before Christmas...we had PHI but after the amount I got back we actually cancelled ours.
I went for a consult and xray -$100, then my first ever filling $250,then a clean $100 got back about$80 - with the cover just under top cover.

With the cleaning they used to put that awful gritty stuff on, but they don't do that anymore (cos they've figured out it wears the enamel away ) so there's a bit of scraping and swooshing and it's over in about 10minutes. The filling invold a local injection, some grinding (which made my brain shake - it didn't hurt but felt yuck) and then the filling bit. The worst bit was that my jaw hurt from having to keep my mouth open.

Good luck hun, hope it's just sensitive teeth.
