There is a big DIFFERENCE between what kind of surgeries or displacements would need to be done to address some kind of jaw imbalance or deviation from balance and YOUR 'need' to have the surgery for it. If you're actually CONSULTING with maxfax docs, it's IMPLICIT to them you are considering surgery for what you have. They're just telling you what the imbalance is and what would BE NEEDED to be done (what they would need to do) to address the imbalance you have. They are just confirming that if you WANT it to address your deviation, they can do surgery for what you have. So, I don't think this is a thing where you're going to a dentist or something like that for a cleaning and their telling you that you 'need' max fax surgery. It's gotta be something where you're actively seeking advice about facial balance.
Given that there are plenty of other people (as in average population) walking around with some form of facial imbalance and are 'surviving aesthetically' with one such that others would still find them attractive in some way despite having some imbalance and/or they are not BOTHERED enough by it to bother with having surgery for it OR to even ask a maxfax what their deviation is, the question you need to ask YOURSELF is what bothers YOU so much that you WANT surgery for it.
You are making good points, however - perhaps surprisingly - it did actually happen to me more than once that general dentists told me I 'should' get this surgery, without me asking, and offered to refer me to a surgeon. This might have something to do with the fact that as GJ mentioned,
Hospitals are businesses these days, and surgery is their most expensive product.
I should add that this happened in non-Western countries and I can actually imagine that the dentist would get a commission for referring patients for surgery. Even when I went to the ENT doctor, it did not cross my mind that the breathing issues had anything to do with my jaws or bite and he started telling me that he thought it was related to that and it would be a good idea for me to get the surgery.
There was even a young male dentist years ago - I went to see him for a filling - that told me really enthusiastically (without me even mentioning the subject) that if I got this surgery I would be stunning and look like a model or something like that. I got quite angry actually and tried to explain to him that it was really unprofessional and also irresponsible to say something like this to a patient but he did not understand what was wrong (again, this happened in a non-Western setting, in other countries I would probably make a formal complaint).
Regarding how I feel: yes, it bothers me that my teeth 'stick out' / are visible even when not smiling, and this is something I wanted to address. That's why I spoke to orthodontists, and without exception they have told me that braces would not really solve this issue. They also told me lots of other scary things like my teeth will 'fall out' if I do not get the surgery, I will have TMJ pain, headaches, digestive problems and so on. The first time they told me all these was over 20 years ago and so far my teeth did not fall out
and I do not have any pain anywhere but I do have the breathing issues now... So I am hoping that if the surgery goes well, it could improve my breathing and my appearance too.
