I wrote an entry this week about sibling teeth on the Sibling Blog. Check it out! Sibling teeth are inherited, and the form and eruption patterns of sibling teeth can be remarkably similar. For example, if one of your children has over retained primary teeth, it is likely that her siblings may also have a delayed eruption pattern. If one child is missing one or more permanent teeth, his siblings may also be missing the same – or mirror – tooth.
But habits also affect the teeth. Thumb sucking, tongue thrusts, blanket sucking can all affect the development of the jaw bones. My patient Melissa had a habit of sucking her middle three fingers but her parents sent her for early orthodontic intervention. She is now a young woman with a lovely smile. Her older brother did not have a finger sucking habit but he was older when he had orthodontic treatment and his smile is not quite so beautiful. The siblingstuff blog has lots of good stuff on siblings. Sibling teeth is one topic.
