I have set up a dentist appointment to have this looked at tomorrow morning, but that gives me a little over 12 hours to stress about the possibilities. So I've come here for some ideas, and hopefully some reassurance.
My symptoms are a sharp pain in my bottom back tooth (has a filling on top, and on the side of tooth)when I bite down on something like bread, or chips, it hits quick and leaves quick. Which leaves me to believe that either the tooth is cracked, or the filling needs to be replaced. This has been going on for about 4 weeks. The tooth is slightly sensitive to cold, not so much hot.
About 2 weeks ago my gum started to ache all along that side, some days more than others. I've kept it really clean, and flossed, I do warm salt water swishes. Heat and massaging the gum feels really good, but it almost makes it hurt more when I stop because it begins to ache.
I grind my teeth, especially while stressing over teeth for a month straight, so I don't know if the gum ache is due to grinding and probing for infections - I look in the mirror about 20 times a day to see if there is any abscess or swelling, everything appears fine, it only bled a when I went a little floss crazy on it. But it feels like something is definitely off.
I'm terrified that I'm going to need an extraction or a root canal. If it's a simple filling replacement at this point it would be a god-send. I know you can't tell without seeing the tooth or xrays, but does this sound like I waited too long to get it fixed and now I'm into some seriously scary territory? The pain has been pretty dull while not biting down, it doesn't wake me up from sleep or anything, but still, there feels like theres a lot going on and I'm worried, or a lot of it can be in my head...what would you guys assume?
