Q. Hi! ive just undergone 3 months of dental treatment to replace all of my old amalgam fillings with “white” ones. one tooth was v bad and i had root canal treatment and now have a lovely new crown. I had the permanent crown fitted 4 days ago (2 teeth back from the upper right canine) but i still feel a little discomfort when i put pressure on it around the gum. Will it settle down? also, ive noticed my back teeth especially the lower ones are sensitive to cold drinks. ive been using a gel at night for over a week but i dont see any difference. im afraid of more root canal treatment….what do u think? is it perhaps caused by the chemicals in the composite fillings that need time to settle? thanking you in advance.
