Q. Hello, my dentist done a cap on my tooth a year ago, but it was the wrong size, it has recently started to smell and cause me some discomfort. When he put the cap in the dentist filed the tooth below, is this good practice? Also he didn’t remove the nerve in the remaing part of the tooth, sould he have? I have now been informed by my dentist that it needs to be replaced (me footing the bill!). I am about to book my appointment, and am concerned about the dentists experience, he said that he will cut the cap, that’s already on my tooth, into four, for removal. Does this sound right, because I am very concerned about the remaining part of tooth underneath. Thank you
