I had my cleaning about a week ago and the hygienist did not mention
anything out of the ordinary, no bleeding, no deep pockets, no cavities,
just one spot where the enamel was worn down. I had mentioned the sore teeth
problem to her and she repeated the problem to the dentist, but he blew it
off. A couple of days ago the pain was back so I stopped to pursue the issue
with the dentist and pointed out to him that there was a crack in one tooth
that I could put my fingernail in. He said something about being an
abfraction and that there was nothing to be filled? He then gave me a
referral for an Orthodontist? WTF?

I went to see another Dentist today who told me I was losing the enamel on
my teeth and that it's no wonder they were sore, as the Dentin was exposed.
He said grinding may be exacerbating the issue, but it is certainly not the
root cause as dentist A indicated. He wanted to know if I'd been sucking
Lemons (LOL), as he'd never seen anything like it before. He suggested a
daily Fluoride rinse and said I should see a root canal specialist to have
the nerves deadened in the more sensitive teeth.

How can two dentists she such different results in the same mouth? I know
dentist A was always after the big jobs (crowns, night guards, etc) and not
too interested in fillings etc. Dentist B was a referral from a friend; she
said Dentist B was also a big Night Guard proponent, but he did not raise it
at all. Although I'm not too keen on his solution, what about protective
coatings, Calcium, etc?

Also, what might be causing this? Diet Soda, Tea, Coffee, medications, acid
reflux, poor nutrition?
