dental lisp
C1technical, medical, semi-formal
Definition
Meaning
A speech sound disorder or pronunciation habit in which the speaker substitutes 'th' sounds (θ, ð) for 's' and 'z' sounds.
A specific type of lisp (sigmatism) caused by placing the tongue against or between the teeth when producing sibilants. In speech therapy and general usage, it can refer to both the condition itself and the characteristic sound it produces. The term is sometimes used metaphorically for any imprecise or muffled speech.
Linguistics
Semantic Notes
While 'lisp' is the general term, 'dental lisp' specifies the articulatory placement (dental). It is one of several types of lisps (e.g., lateral lisp). In non-technical contexts, it is often simply called a lisp.

Memory Aids
Mnemonic
Think DENTAL = TEETH. A DENTAL LISP happens when your tongue touches your TEETH for 'S' sounds, making 'soup' sound like 'thoup'.
Conceptual Metaphor
ARTICULATION IS PRECISION ENGINEERING / SPEECH IS A CLEAR CHANNEL. A dental lisp represents a misalignment in the 'machinery' of speech or static on the 'channel' of communication.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)

- The closest equivalent is 'межзубный сигматизм' or 'шепелявость', but 'dental lisp' is the specific English term.
- Do not confuse with a general speech defect ('дефект речи'); it is a specific subtype.
Common Mistakes
- Misspelling as 'dental lips'.
- Using 'lisp' alone when the dental aspect is the key detail.
- Confusing it with a lateral lisp, which produces a 'slushy' sound.

Frequently Asked Questions

Yes, adults can successfully correct a dental lisp through targeted speech therapy, though it may require more conscious effort and practice compared to treating it in childhood.
In speech-language pathology, a persistent dental lisp beyond a certain developmental age (often around 4.5-5 years) is classified as a speech sound disorder or articulation disorder.
It does not affect the ability to learn vocabulary or grammar. However, it can make pronunciation of specific sounds in English and other languages challenging and may affect intelligibility and speaker confidence.
