LeQ and Soup
I think you are missing my point: I already said if this is strictly medically necessary, it's a different story.
I grew up with a younger sister who had years of cancer treatment, so believe me, I know all about forcing a young child to take medicine they don't want to! One of my first Major Ethical Dilemmas in life, when I was in primary school, was whether to tell my mum that I knew DSis was hiding her pills behind the bookcase in our bedroom rather than taking them.....
However, a lot of people here bang on about 'It'll be worth it when she has straight teeth'.
Well, no. Straight teeth aren't the be-all and end-all. A person has a right to decide they don't want to conform to that image (again, I had voluntary ortho treatment so don't agree with that, but still). Also, often ortho treatment isn't successful: I was super-good about mine, but when my wisdom teeth came in all that good work was destroyed.
Also LeQ forgive me, but I am guessing you have not had braces yourself? Read gin's post above. It is not just 'a few weeks of discomfort'. It can be months or even a year or more of pain, where your teeth and whole head ache, where you feel too miserable to eat and talking hurts because your lips snag over the exposed metal on the brace. Mine was not that bad but I have scars on the inside of my mouth from where the brace wore away at my skin; drinking absolutely killed for weeks after it was fitted. I consented, but I cannot imagine visiting this on a child if they were adamant they didn't want it and it was not absolutely medically necessary.
Links with later heart disease etc are a red herring as this treatment can be done when the child is older, even if this isn't ideal, and there are lots of other ways to reduce risk of HD.
However, I accept I am in the minority. I strongly believe that you cannot force an 11yo to have a life-changing medical procedure they don't want. I really don't think it is the same as giving them Mars bars for tea if they ask. A painful, invasive procedure is different.
Seriously, if you thought your DD was sexually active - or just had painful periods - would you have her forcibly fitted with a coil? It might be medically helpful, but it is not like taking anti-Bs, imo.
