Dental problem any advice from anyone or those who work in dental field?

Had tooth pain, upper tooth in middle, dentist removed infection put in filling drilled tooth down and put an inlay/onlay over it, I would call it half a crown, a bit on top of tooth. Few weeks later and it still hurts but it will hurt for few days then stop few days and go on that way. Dentist said other option to have it out, every time I go its costing me a lot of money even on NHS side. I considered a crown but figure it will still hurt so maybe should have it yanked even though its on the side. The pain radiates from my gum not actual tooth but when pressure put down on tooth it starts it off, any ideas anyone?
