I got braces about 2 years ago. I opted for regular braces because it was a little cheaper. But, mostly because I knew that I would not wear the invisalign everyday. I now have a retainer and I am suppose to wear it every night. I usually wear it about 2-3 nights a week. I simply forget. I can't imagine a 12 year old would be anymore responsible. Keep in mind the cost of replacing them when they get lost.
