I agree. My rule of thumb is if the wait is long then the dentist is doing their job, and be worried if not. A decade ago, I had a young dentist with a new practice with a large office, new gorgeous equipment, and no wait. He recommended that my later described as cracked tooth should be replaced with crowns or implants. He kept on asking if my teeth were sensitive and should be replaced, and gave me a used car salesperson shrug when I said I'd think about it. Almost a decade later due to such silly advice, I finally went to another dentist with a 6 month wait for an appointment and a nice but tiny office. They said they would put a protective sealant on my now described cracked tooth, and it's been going strong since then. Good advice and outcomes comes with a wait.
