One of my front teeth has slowly grown more dark over the years, and my dentist has recommended that I get a root canal done on it. She also mentioned that the existing pulp would need to be sucked out, to internally clean the tooth, then inject some filler before doing the root canal. Does that sound safe, for a tooth as important as a front tooth? And if so, how much is a reasonable expense to expect for the whole operation in a place like manhattan? Is it worth it to get a veneer afterwards as well? Finally, if you could recommend any dentists who would be good, I would greatly appreciate it! Thanks in advance.
