Self-perception can have a profound effect on one's physical and mental wellbeing, so even drugs which are for cosmetic purposes can be important for health.
True, and, I'd posit that there are often better and safer alternatives that would be similarly or more beneficial with less potential for harmful side effects.
I have several anecdotes from my own life. When I was ~18 the doctor proposed to give me jaw surgery to fix my overbite by extending my lower jaw. I asked him what the reasons for this were and he said it was mainly cosmetic. I thought this was not a good enough reason for surgery - which while often safe does also often have harmful side effects - I now know way too many people who had surgery complications that often took a long time for them to become aware of. I think I feel better about myself now for having made that choice than I imagine I would if I had a better jaw line.
It's true that some people are going to have a story where they see the cosmetic medical intervention as having been beneficial for their mental wellbeing. I'd still suggest that in many such cases there might have been other ways to get a better outcome. It's for each of us to decide.
Still, burden of proof of the safety of a drug should be on the company profiting from it.
I think to just brush over surgery fixing a malloclusion as "cosmetic" as if it's kind of a trite thing just doesnt seem right. There's definitely risks since there's a lot of nerves that can get botched in jaw surgeries causing different problems.
I can tell you tho I would never consider it just so superficial. A lot of unconscious behavior happens based on facial symmetry that is hard wired into us. Malloclusions can effect breathing especially at night (some problems that will only surface later in life when options to fix limited by your age), the way other parts of your face look such as the nose, oral health, long term root problems, uneven wear etc etc
I had a doctor that just shrugged his shoulders and said the same thing to me. I wish id had a doctor that pressed me a little to really think about the long term picture when I had the chance.
If theres already problems like pain etc then obviously the justification is more than cosmetic.
I dont know if you are still young enough I would reconsider. I think in general overbites are still more bearable than under.
I don't want to claim that it's always just cosmetic or that no one should ever get it, but my point is sometimes there are alternatives that don't carry the risks.
Another related anecdote from my own life, I had sleep apnea from when I was a teenager. Another doctor also proposed surgery to fix my nose for that, but somehow I'd become skeptical of doctors wanting to do surgery (probably I'd heard too many stories of something going wrong.) Anyway, a year ago I fixed my sleep apnea using a nose dilator and mouth tape at night for a month. I still have overbite but mostly breathe through my nose now.
Again, not saying that surgery or intervention is always bad, but this was an even more extreme case where they wanted to do surgery to fix something that could be fixed in a much more natural and much easier and extremely cheap way, but the natural way was never mentioned by a doctor, I only heard about it from a friend 15+ years later. And it just worked, and for the past year I've not had sleep apnea - I sleep better, don't snore anymore, and can breathe enough through my nose now while exercising etc. i.e. the nose must have been able to reshape itself with the help of the dilator and necessity (because the mouth was taped). I still have overbite but I'm not sure it's really a problem especially compared with the risks of surgery.
