Do I need a root canal?

Jan 9, 2023
I have a problem on #29. It’s been 10 weeks since I got my filling done the first time and it has been sensitive to hot/cold substances since then. The sensitivity lasts <5 seconds and it goes away, there are no other issues. It almost feels like a “snap” of pain and the sensitivity goes away almost immediately. There has been no improvement and it hasn’t gotten worse.

I got my part of my filling replaced (at my request) 2 weeks ago. The doctor only replaced the side of my filling, not the filling on top of the nerve. I said I just wanted to replace that side because it was cracked and I was hoping the sensitivity would go away after that. I was wrong and it didn’t help at all. I went back to the dentist and he refused to replace my whole filling because he didn’t want to keep drilling in the tooth and referred me to an Endodontist for a root canal. He said he’s a specialist and will do some 3D imaging or something so I can know for sure if I need one or not.

I feel like my case is borderline and I’d rather not get a root canal if I can help it. I’ll get one if I really NEED it, but the only issue I have is sensitivity to hot/cold that goes away after a few seconds. My dentist said my nerve is close to the top of my tooth and that’s why it’s sensitive. I feel like I’m not going to know for sure unless I get the whole thing replaced.

If I keep drilling in my tooth will it make my sensitivity worse? I’ve had 2 fillings done in the past 10 weeks on that tooth.

What will an Endodontist do differently than a dentist? Will he just immediately say I need a root canal because I was referred or will he examine my tooth on a case by case basis? On the referral my dentist wrote “evaluate 29 and treat as necessary”
