We recently moved and my wife & I both scheduled checkups at the same new dentist. She recommended a crown replacement and Invisalign to both of us, in my case while wearing an Invisalign-branded face shield. We both got weird vibes from that place and don't intend to go back. Didn't help that the hygienist said something like "oh, the crown replacement is easy, we just got a brand new machine to make them in-house!" which sounds to me like "wow we really need to pay off this machine"
