Not feeling confident in dentist visit, teeth still issue

[A196x]

Hi,
I visited my dentist today as ever since Sunday (after drinks) I have had pain on chewing with my two big teeth on the right and left. Sometimes after eating there is a dull ache lingering! I then went to my dentist today and they said due to my TMJ they’ll not do a filling and the sensitivity is due to acid reflux wear. They did put a gel thing on my teeth it was a brown colour and think it might’ve been fluoride stuff, he said I could eat an hour after it. Yet ever since this thing has been applied the sensitivity has worsened and it feels it’s made my teeth odd/higher does this thing brush off? And what is the alternative if my sensitivity and pain does not go? Panicking

(the sensitivity is occuring during any foods and drinks)

the dentist also took x rays of back teeth which have came back fine but what would a xray even show?

So I think it was Fluoride varnish, teeth still achey today but unsure if that varnish has made worse. I’m feeling if this pain and sensitivity doesn’t go (

F varnish wears off fairly quickly. If that doesn't work there are other non-invasive things they can try. The varnish sometimes needs multiple applications to work, so don't panic and do go back to let them try again if it hasn't fixed it.
