Botox as a dentist has some upsides and downsides. Yup, its easy to do with just a simple injection into areas that we've spent a TON of time studying anatomically and bascially inject into already, and its done on a patient base who most of the time who would be definate candidates for the highly profitable cosmetic cases that can be fun to do.
On the minus side, this same patient population(which tends to be women in their 30's to 50's) can be some real PITA's to work on and will often find the most minute and imperceptable detail to harp on and fill up your schedule with and drive you crazy. I've seen it all too many times, where the reason for the cosmetic "enhancements" is a deep and long standing insecurity about one's appearance which often takes way more than some fuller lips or bleach 1 shade of veneers to fix.😱
