Know anyone with a lisp?
There are 4 types:
1- frontal/ interdental lisp- the most common and occurs when the tongue pushes too far forward between the top and bottom front teeth.
2-lateral lisp- air moves over the sides of the tongue when speaking, causing slurred sound.
3- palatal lisps- the tongue touches the roof of the mouth while saying certain sounds.
4- dental lisps- are easily confused with frontal lisps, but occurs when the tongue pushes against the teeth — not through them.
A lisp can affect teeth alignment and the way a person produces word sounds.
In most cases, a lisp is not developmental in nature, but rather a deviation in tongue placement at rest or during speech (and swallowing). Many young children do present with interdental lisps and this is considered age appropriate until approximately 4-5 years of age. Lateral and palatal lisps are never considered developmentally appropriate.
A speech language pathologist should be consulted as soon as possible for an evaluation as it is easier to correct, the younger a person is, but it is never too late to seek speech therapy for a lisp as adults can also receive services related to a lisp.
