I'm not sure what "damon" braces are, but my 9 year old just had phase one of braces removed from her teeth, and it was the best thing we could have done for her. I think it depends on the kid, and what the problem is. I have an 12 yr old that had all of her adult teeth at 9, and they put the one and only set on then, which has been perfect for her. My 9 yr old is a different story. When she was 7 and her top adult teeth started coming in, she had a huge overbite, and her adult teeth were/are very large. When the next 2 top teeth (to the side of the front 2 top teeth) started to come in, they were coming in really high, almost at the top of the gums. The ortho thought it was important to #1 - correct the overbite so that there wouldn't be any damage to those front teet (he read me a startling statistic of kids who lose their front teeth from falls, etc... if they have an overbite) and #2 - bring the other 2 teeth down and into alignment with the rest of her teeth. It was understood that they would be on for a year or so, and then removed, and then she would probably need teeth pulled, and braces put on again when all of her adult teeth came in. To make a long story a little shorter, after about 18 months in braces, she had them off a couple of weeks ago. She has a beautiful smile. Her teeth were so bad before, she was embarrassed about them. So, my opinion is to first and foremost, get an orthodontist that you completely trust. In my daughter's case, the 1st phase was necessary not only for cosmetic reasons, but to make the next phase a lot easier and smoother. I know my ortho wouldn't have recommended it if it weren't necessary, in fact I know he is usually against doing 2 phases of braces, so really figure out if it is necessary!!! Also, I think $8,000 is a bit steep. We paid $1500 for phase 1, and will probably pay around $4000-$4500 for phase 2. You may want to shop around.
