Only joking.
It is hard dealing with services who's income is very reliant on their customers needing to trust opinions. Doctors, Denstists, Mechanics, Plumbers, etc... business model is such that they need problems to fix, and the everyday person often doesn't know if those recommended problems truly need fixed or if they're being taken advantage of. Not saying it's bad, just the way it is. We've all certainly had mechanics try to up-sell us on services we don't need. While I think people in the medical industry are much less likely to do that than a mechanic, it's certainly possible.
Personal anecdote: When I was young, I had 4 adult molars pulled because I my adult teeth grew too early and my mouth didn't have room. Then in high school, we did the typical trip to the oral surgeon to determine if I needed my wisdom teeth out (since that is a thing it seems almost everyone does just by default). Oral surgeon said "yep, lets cut those babies out, and we scheduled an appointment". However, my mom had some background in the medical field, and looking at the x-rays, the wisdom teeth appeared to be perfectly straight, so she wondered why they needed to come out. She then took me to our family dentist to get his opinion. He said there was no reason to cut them out. Let them grow in and see what happens. If they give me problems, just have them removed then. Since I was missing adult molars, I should have had room for them. I'm now 37 and have had zero issues with my wisdom teeth.
Why did the oral surgeon tell me I needed to undergo a pretty painful and expensive procedure? I'm actually still resentful about it to this day, although I have had nothing but good experiences with Dentists since then.
