Is it ok to use whitening strips if your teeth arn't fully grown?

I want to get my teeth whiter with whitening strips, but i'm 14 so my teeth aren't done growing. Is it ok to use them?

Too cute :) Do you really have any baby teeth left? If you are 14, you probably have all your adult teeth. Teeth don't really grow any more after they come in. It should be fine to use white strips.
