My eye doctor a few years back tried to get me to get some kind of treatment (a device or some snake oil potion, can't recall) because I was allegedly not blinking enough and had dry eyes that could spiral into (insert mildly scary eye disease) if left untreated. Some googling helped me reach the same conclusion as this blogger. So it's not just dentists... at least my dermatologist is pretty transparent about all the aesthetic treatments that complement their medical services, though they seem to always find a mole that needs a biopsy and every year it turns out benign. I wonder how many times it was necessary, versus how many times it was just an easy money grab because my insurance covers it and it's very minimal of a procedure. I don't have a problem with for-profit healthcare, but fee-for-service is driving the insane cost inflation in the US
