Diver Getting His Teeth Cleaned By Fish Is Viscerally UpsettingBryan Menegus8/18/16 2:47pm4711EditPromoteGo to permalink Hey buddo, I get it. Going to the dentist is no fun and fish need to eat. It’s logical—symbiotic even. And fish aren’t going to chastise you about cavities, or drinking too much coffee, or not flossing. And they won’t try to talk to you about classic cars while inside your mouth (looking at you, Dr. Gershon).
