Can Brace Help Align Lower Jaw if Teeth is Not Straight to Begin With?

NO. Removing wisdom teeth will not alleviate crowding of teeth, nor will it create a slimmer jaw. It is actually second molars that cause a forward thrust on the jaws and create crowding. This is why lower anterior teeth will almost always become crowded, even after initially straightened, unless a patient wears a retainer. Hope this answers your question. Good luck!
