root treatment - TN

[agbee]

Hello, my problem is: the 4th right side upper tooth became quite sensitive (reaction to cold and hot) a while ago, so my dentist took an x ray and didn't see anything wrong with it. He also referred me to a dental surgeon, who also said he couldn't see anything wrong. Then the tooth got worse, so the dentist took the nerve out, did the root treatment, took another x ray which shown it was done properly and told me to come back 7 days later to get a permanent filling. Also the dentist said the tooth was with no cavity inside and the nerve looked wick, but not infected. As it was still bothering me, I had a CT and a MRT done, which shown there was nothing wrong with my whole head.  After 7 days the dentist made a tooth restauration by using a pin, and my tooth got even worse.
So my first question is: could possibly the pin push the root filling inside?  
And my second question: they suppose I am suffering from a TN (the pain appears inside of my face next to the nose and goes in my eye and my teeth 4,5). Could it be the reason why my tooth got sensitive and still is bothering me even after I had a root treatment?
I just want to know if I should seak another opinion about my tooth situation or just concentrate on the TN treatment.
Thank you very much.

If the pain is caused by trigeminal neuralgia or atypical odontalgia, Dental condition probably has nothing to do with the pain, because enen if there is no tooth of pain site , pain is still present. If the pain is caused by referred pain from myofascial trigger point  of masticatory muscle or occlusal interference, dental occlusion is a significant contributing factor.

One more detail: the 6th lower tooth (right side) is missing (was extracted more  than 3 years ago), and my dentist said that my bite started changing (by nature it was ideally right). Just a guess: could it be the reason of the pain and the reason of the wedge-shaped defect on some other teeth?

They are in private practice in the UK, I checked. The difference is: to reach them via the NHS will take months, privately - a couple of days.
Thank you so much, Scottma, if you ever come to work in London please let me know.

I believe an orofacial pain specialist would be the first choice  to manage your problem .However, these specialist are probably not in private practice.Dental school is probably the place they practise.

Thank you, Scottma!  Who is better to be seen by - neurologyst or orofacial pain specialist? Just dealing with my insurance company at the moment and not sure if they would cover 2 specialists.

It appears that the problematic tooth is #4, second bicuspid. There was no dental, bone, and sinus pathology identified. Based on the information provided, the differential diagnoses include occlusal interference , atypical odontalgia, trigeminal neuralgia, myofascial trigger point referred pain. Seeing an orofacial pain specialist is advised.
