I broke my front tooth years ago. I went to a pricey cosmetic dentist and he said a root canal and porcelain crown will improve the aesthetic appearance ensuring it matches the other tooth. He has put in a temporary crown until a permanent crown is made in a lab. The temporary crown looks far worse than my previous tooth. Before I left, he seemed to think it looked natural which has made me worried about the final outcome. See before and after photos. Your views?
