Hi I would like to ask you a question regarding tooth contouring and reshaping, I am an 18 year old male and reasonably healthy teeth but I don’t like the shape of them never have, is it possible to in a way sand them down lol the front two teeth look like bunny teeth most would argue they’re fine but I am not confident with them, I also have a pair of two teeth on the top and bottom of my jaw that are sharp could they be contoured into a more attractive square shape?

Thanks
