Hi..yes it works. Braces can be placed till age 45 also. Teeth,bone and gums should be strong. Regards

Yes, the clips do work to align front as well as back teeth and that too in a very good shape and line. You just need patience as the treatment takes a bit long time which depends upon the present alignment of your teeth. This treatment can be done at any age but the sooner you get it done, results will be better and will take less time. Regards.
