I recently got dental insurance, so after 4 years of not seeing a
dentist, I decided to go get a checkup.

Turns out I have 6 cavities.  All, which, they say are either on top or
underneath my older composite fillings. Two weeks ago they filled my
lower three right teeth, since then I have been having extreme
sensitivity when I touch the middle back tooth. It's also like a
shooting pain when I eat and the food (even soft things like bread)
causes immenses shooting pain which goes away after I stop chewing!

I went back to the dentist today (they had me scheduled for the other 3
fillings) and I told them that I didn't want to touch the teeth on the
other side until the tooth on the left was relieved of it's sensitivity
pain....I can't chew on that side!

So he takes a look at it and says that it just needs to be drilled down
a little bit. I kept telling him that I didn't feel pain when biting
down, just when I bite down on food or touch it with my finger. He
didn't seem to be listening to me because he kept asking me to bite
down and if there was pain!

He starts drilling on my sensitive tooth (WITHOUT NOVACANE) and i
screamed. OUCH right? If bread hurts it I AM 110% SURE THAT A DRILL
WILL HURT IT AS WELL. I swear this dentist was a dummy. I told him to
stop and he put three shots of novacane in the tooth and continued
drilling.

I was numb so I couldn't tell whether I had improvement or not at the
time. I asked him if there wasn't any improvement in a few weeks what
would happen? And he said "ROOT CANAL".

I'm starting to think all this guy wants is my money. I asked to look
at the x-rays and he was like "look, see, your previous filling was
close to the nerve, so this one's even closer..." And then I asked him
about the possibility of perhaps the composite filling not being bonded
correctly (it was a molar, and a large filling, and they only put the
curing light on it once....) and that  redoing the filling would help
(I read it all over the internet) and he said that "it's not possible,
we've come a long way in modern technology and that doesn't happen
anymore".

it's just ridiculous, if I have to get a root canal done on this tooth.
I almost don't want to get my other fillings fixed because they
"looked" close to the root too and I"m not having any problems with
them and the last thing I want to do is get 3 more fillings and then
end up with 3 more teeth that need root canals.

What do you guys think? Should I go to a new dentist?

Now I as I am sitting here typing this, (numb sensation is gone) I
clench my teeth together , and on release I feel pain in that tooth
(wasn't there before the DRILLING DOWN)
