the reason chris People are telling you to see a dentist is because we care..No one wants you to do more damage ,and i am sure your parent/s don't either..
Braces are expensive..and if you do have a loose tooth..You should get it checked..like some said it could be normal..but there may be a slight chance that it may not as well..that slight chance may mean saving an Adult tooth ..which cannot be replaced...once its gone ..its gone..And an implant tooth is very expensive as well.
Any medical query should be treated with respect for your body..and respect means "making sure" if everything is ok..and treating things early with professional care.

After Braces (Orthodontics):
It is quite common for some teeth to be slightly loose during and after the wearing of braces. This is caused by the process of pressure on the teeth by the braces and their response to the pressure exerted by the brackets and wires on your teeth. Special cells remove bone on one side of each tooth and build bone on the opposite side. This process allows teeth to move through bone. Until all the bone has filled back in, teeth may be noticeably loose.
Treatment:
Contact your orthodontist.
It doesnt say .."dont contact your orthodontist..it says contact him/her)
look after yourself Chris please..
