I have a few dilemmas, I went in for a root canal and a filling was placed on my front tooth causing it to look slightly longer than the one next to it. I want my smile to look straight so the dentist suggested to place a filling on the other tooth so that both teeth look even, but he said that i run a risk of the teeth chipping. Would i be able to reshape my teeth so that my smile looks even? Also, i have a bridge that was placed about 5 yrs ago and i didnt have any discomfort, but when i went in for a check up i found out that the tooth holding the bridge was decaying due to the bridge not being in place the correct way there was a small gap that the dentist didnt see where food was coming in (this whole time food was accumulating causing the tooth to decay) so now they want to pull that tooth out and make a new bridge. Is this type of neglect the doctors fault? Should i seek a different opinion?
