Question

I work with a 4th grader who has the most serious case of misaligned and protruding teeth I have seen. His mother tells me that the dentist will work with his teeth after his lower jaw grows, which they expect to be when he is 15. He of course has troubl

Answer

It is apparent from your description, that your client has upper lip incompetence from his "misaligned and protruding teeth." I am going to assume that his only misarticulations are bilabial-stop plosives. Without medical/dental intervention, working on improving the range of motion (ROM) of his lips and working on compensatory strategies is the path to take. We need to remember that the primary purpose of the respiratory, articulatory, and laryngeal systems is breathing and feeding. The speech mechanism is able to generate much more force and structural displacement than is necessary for the production of speech, and it is capable of making significant compensation for structural and functional insufficiency (Peterson & Marquart, 1994). So you may be able to help him improve intelligibility with ROM exercises and compensatory strategies. Personally, I would look for a second opinion from another dentist--age 15 just seems a little late to me.
