no it’s more complicated than that, you need a full estimate on the letterhead from the Dentist, in my case I asked for a quote for seven crowns to be removed and new ones put in, I asked them to put in a panoramic x-ray, a full cleaning and a check up, comprehensive dental work, not just an appointment, the dentist signed the letter, but my wife and I already have a relationship with this dentist so that made it easier
