That's what they are supposed to do. The drawback is roots get shorter you lose some strength and they will always want to move back so have to watch them after
Braces can be used to move teeth.
There's really no limit, you can get braces as an adult. It'll take a little longer for the teeth to move around, that's all.
yes you have to have braces on if your teeth are bad or less your teeth will move alone and your mouth will be weird
No, they are devices to move crooked teeth.
No not unless you have braces or some other appliance moving your bottom teeth.
Yes, it happens while trying to move other teeth. When the orthodontist finds it, or is doing fine tuning with your teeth, s/he will fix it.
Braces are designed to move your teeth into better alignment. A retainer is designed to keep your teeth in their current position following braces. If your teeth are where you want them to be, you do not need braces or a retainer. If they are not, you will need to have them moved with braces followed by a retainer to hold them in place.
They shouldn't move back to their original positions. The whole purpose of braces is to properly align teeth. You may be given a 'retainer' after the braces are removed; this is put on at night for a few months to make sure that the teeth stay where the braces put them.
Yes. That is what braces are for. It takes a while, but they do move.
Orthodontists will want certain teeth extracted (usually premolars) to make more room in your mouth so they can align your teeth properly. Your mouth and jaw may be too small for all your teeth.
Yes as they quickly move teeth to close spaces.
Once the teeth have been moved into their new position, the braces are removed and a retainer is worn until the teeth stabilize in that position. Retainers do not move teeth, they only hold them in place.
