Is There Really a Right Time to Get Braces?

Parents usually have the notion that the earlier their kids have braces if necessary, the better the success rate would be in correcting their overbites.

An article published in 2007 by the Cochrane Library in the UK says that kids with overbites can still be successfully corrected whether they start early or late. One limitation of the article though is that it only focused on overbites. Some dentists say that other treatments should be started early rather than late, one example being asymmetric teeth growth, which needs to be corrected while the bones are not that hardened yet.

In conclusion, experts say that it really is on a case-to-case basis.
