Editing Labiodental consonant (section)

=={{vanchor|Dentolabial}} consonants==
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 to the International Phonetic Alphabet|extensions of the IPA]] for disordered speech is a superscript bridge, {{angbr IPA|◌͆}}, by analogy with the subscript bridge used for labiodentals: thus {{angbr IPA|m͆ p͆ b͆ f͆ v͆}}. Complex consonants such as affricates, prenasalized stops and the like are also possible.
These are rare cross-linguistically, likely due to the prevalence of [[malocclusion|dental malocclusions]] (especially [[retrognathism]]) that make them difficult to produce,<ref>{{cite journal |pmid=33441808 |date=2021 |last1=Everett |first1=C. |last2=Chen |first2=S. |title=Speech adapts to differences in dentition within and across populations |journal=Scientific Reports |volume=11 |issue=1 |page=1066 |doi=10.1038/s41598-020-80190-8 |pmc=7806889 }}</ref> though the voiceless dentolabial fricative {{IPA|[f͆]}} is used in some of the southwestern dialects of [[Greenlandic language|Greenlandic]].{{sfnp|Vebæk|2006|p=20}}
