Well when it comes to teeth, I am the expert!
Cosmedic repairs are what they are, REPAIRS to something that will break again! Root canals are 50/50 because odds are always good it will turn black and then you will want it pulled.
The bottom line some dentists concider you a investment because without you no $$$$$$$.
I've had to fight with dentist to pull the tooth and still they try to sell me on a reason why I should pay & pay when to tooth is done, they offer root canal to kill the nerve then fill it then it bothers you for days sometimes weeks then before you know it it's turning grey then black.
But on the bright side the dentist will offer a nice white surface to cover the black while he bills you more green $$$$$$$
The cycle continues.
I'm sure there are good dentists but they all want $$$$$$$.
