i have a good tooth in my front upper jaw (central incisor 1) but its twisted and is overlapping upon its next one (another central incisor. Now thats making my smile look bad. I have seen a dentist and he, after examining x-rays, told theres no space between my teeth and brace are not an option for me. then he suggested me a solution that is he will grind the tooth and root canal and then put on a crown.

is it ok?? is what the doctor saying right? after coming back home i got a question that is why do i need a root canal? Cant i simply grind and wear the crown?

is this the right solution that he suggested.. is there any new technology in the developed world?
