Tongue Position for /s/ with Open Bite

Question

Answer

There are two positions we can use to produce and /s/. One is the more traditionally taught "tongue tip on the alveolar ridge." The other is with the tongue tip positioned behind the lower teeth. The latter position is the position I would try if working with a child with an open-bite. It is also the position I use when teaching /s/ to a child who is severely tongue tied. For this technique the tongue tip is behind the bottom teeth and the tongue blade makes contact with the alveolar ridge. Additionally, central airflow is fairly easy to maintain. Although it may not feel quite as natural if you are a "tongue tip on the alveolar ridge" producer of /s/, but you can achieve a quality /s/ using the lower position.

For the second question the answer is, "no." I think it is important for us to remember that speech is a secondary function of the oral mechanism. Consequently there can some degree of variability in its structure and function before it affects speech production. Although in my practice I have seen children with co-occurring frontal lisps and tongue thrusts, I have also seen both of those disorders occur independently.
