The diacritic for bidental consonants in the extensions to the IPA is the same superscript plus subscript bridge, ⟨◌̪͆⟩.
This is used for sounds most commonly found in disordered speech: People with hypoglossia (abnormally small tongue) may use bidental fricatives for target /s/ and /z/.
There is at least one confirmed attestation of a bidental consonant in normal language.
The Black Sea sub-dialect of the Shapsug dialect of Adyghe has a voiceless bidental fricative where other dialects have [x], as in хы [xə]ⓘ "six" and дахэ [daːxa]ⓘ "beautiful".
