In phonetics, dentolabial consonants are the articulatory opposite of labiodentals: They are pronounced by contacting lower teeth against the upper lip. The diacritic for dentolabial in the extensions of the IPA for disordered speech is a superscript bridge, , by analogy with the subscript bridge used for labiodentals: thus . These are rare cross-linguistically in non-disordered speech, likely due to the prevalence of dental malocclusions (especially retrognathism) that make them difficult to produce, though the voiceless dentolabial fricative is used in some of the southwestern dialects of Greenlandic.
