But Do I Have Any Cavities?
Every dentist and dental hygienist who has ever examined a patient has run into this frustrating failure to communicate. During your examination you found three teeth with 25 year old failed amalgams. You've described to your patient in exhaustive detail about the wide open margins, leakage of saliva and bacteria, and new decay now undermining the old mercury silver filling.
Your patient bobbed her head up and down indicating (or so you thought) her understanding of the situation. At the end of your speech the patient then asks, "But do I have any cavities?!?"
