teeth hurt when eating hard/crunchy food?

[1398_Days]

My molars on my top right side hurt when I eat anything hard or crunchy. Well, they don't actually hurt WHILE I'm eating but afterwards it's like they're sore and I just have this dull ache for a while. I even woke up this morning with my teeth aching a bit. I'm almost certain that I clench my teeth at night (only when i'm stressed or something, which i have been) but this only started after I got fillings on my molars back there.. about 7 months ago. But I'm wondering if my bite just needs to be adjusted? I'm almost embarrassed to call my dentist at this point, almost 7 months later AND I got my teeth cleaned last week (no cavities and he said my teeth look good) and forgot to mention it. I just keep forgetting because it doesn't happen all the time. My teeth are kind of sore for a day or two and then it goes away and I just completely forget about it. It also worries me a bit because when he was doing one of the fillings he said it was so deep that he almost thought I would need a root canal or extraction, so could it just be because the filling is so deep? If so, is that something that I need to worry about? Can I just leave it or would I need a root canal?

Might want to visit your dentist to check for cracks in the tooth. If the tooth is heavily filled then that weak tooth is more likely to develop spots which are prone to crack over time.
