I was about to get a root canal and crown. They are expensive and they try to hard sell you things you dont necessarily need. I wanted to get a regular noble base porcelin crown, but they hard sell me their new much more expensive all porcelin crown for $1500 when I told them my old dentist told me a regular crown is only $800. They claim their crown is much better and they try to scare into their crowns by saying their not gonna guarantee anything when my crown falls off from another dentist. I got another crown from another dentist for $450 and one year later its still perfect
