Q: My client has an anterior open bite, a very strong thumbsucking habit, and a frontal lisp of S and Z. My first impression is to wait to work on speech until after the teeth are firmly in place and the sucking habit is eliminated. Do you agree with this? Yes. In regard to the teeth, it is my opinion that it does no good to work on the sibilants until the “anterior dental barrier” (consisting of the front teeth)…
