Help any dentists? Need to advise

[Groundhog88]

For the last few months I’ve had a pain in the corner of my back molar near the gum line.
I’ve been to the dentist numerous times had 2 x-rays that apparently show no cavity.

But it feels different like there is a hole but dentist could not see anything. Feels strange when I put pressure on that corner and I’m getting bad sensitivity when hot or cold goes on that spot now.

Could this be a crack in the tooth? I asked the dentist and she just fobbed me off saying it would not show on X-ray and just to use sensitive toothpaste.

I’m so fed up the pain is making me feel sick. I’m trying to not eat on that side of my mouth as I’ve found if I leave it alone it eases it a bit.

Should I just get the tooth out? As I can’t live like this anymore.

Thank you for any advice.

Weirdly I just saw a TikTok about an American guy who had been to the dentist numerous times saying his back teeth weren’t right and he felt awful. The video was because he went to a specialist that did an MRI and it showed up 3 large abscesses, one of which had gone through the back of his jaw bone exposing his tooth roots.
The dentist was saying they wouldn’t show on an X-ray, which I didn’t know was a thing. I was wondering how many people suffer because an X-ray doesn’t show up anything! I’m having awful issues but have had half a dozen X-rays and keep being told everything looks fine!

Could you ask for a referral to Max facial? I was referred a few years ago for another issue and did have an MRI that time, no chance now though. My Dentist (NHS thankfully) has just cancelled an appointment I had booked for several months and said not to phone for a new one until 2025 as they have lost a couple of dentists and can now only deal with urgent cases. How daily pain, that even wakes you in night, isn’t something that needs dealing with I don’t know.

If it is sensitive to cold and the pain is very short lived either when biting and/or with cold or sweet food it’s likely to be a fracture. If it hasn’t advanced rapidly to abscess the fracture probably isn’t through to the nerve but just into dentine.
Options are

1. do nothing and treat with sensitive formula toothpaste ( use like an ointment)
2. if the tooth is filled - remove filling and locate fracture sometimes you can remove the fractured portion and refill or maybe seal it
3. crown the tooth - pretty old school treatment and not always appropriate or successful
4. have the tooth extracted- this was my choice when my back upper molar fractured. I put up with it for 2.5yrs when it abscessed so had it removed pronto, haven’t looked back. You can’t see its missing and it doesn’t affect chewing.

If the tooth dies off you could consider root treatment but when a tooth is fractured the success rate is lowered.
