I used to have high respect for people in the medical profession like dentists. Today I went to a new dentist for a 45-minute routine hygiene appointment (essentially teeth cleaning). It only took him 20 minutes and he explained to me that there was nothing more to clean. However, he suggested me to try “sparkle airflow polish” to remove the coffee stain on my teeth. I was a bit alarmed as I did not realize it was this bad. I asked him where the stain was. He handed me a mirror and showed me a tiny spot (the size of toothpick tip) on the back of one of my teeth. I said in the calmest voice possible (with just a very light touch of sarcasm) that if I can’t see it myself, I don’t think it will bother anyone. I left swiftly (or “stormed out” more precisely) before he tried to “sell me the Brooklyn Bridge”!
