I notice that my son's teeth are sticking out. Will he get worse as he grows older?

You should be careful! Front teeth that stick out (large overjet) can worsen as your son grows older. Protruding teeth are more prone to injury and can lead to poor appearance. Protruded upper teeth are commonly associated with a lower jaw that is too short or an upper jaw that is too long. Thumb sucking habits can also cause upper front teeth to stick out.
