For many languages, such as Albanian or Russian, velarization is generally associated with more dental articulations of coronal consonants so that velarized consonants (such as Albanian /ɫ/) tend to be dental or denti-alveolar while non-velarized consonants tend to be retracted to an alveolar position.[1]

Sanskrit, Hindi and all other Indic languages have an entire set of dental plosives which occur phonemically as voiced and voiceless, and with or without aspiration. The nasal stop /n/ also exists in these languages, but is quite alveolar and apical in articulation.[citation needed] To the Indian speaker, the alveolar /t/ and /d/ of English sound more like the corresponding retroflex consonants of his own language than like the dentals.[citation needed]

Spanish /t/ and /d/ are laminal denti-alveolar[2] while /l/ and /n/ are prototypically alveolar but assimilate to the place of articulation of a following consonant. Likewise, Italian /t/, /d/, /t͡s/, /d͡z/ are denti-alveolar ([t̪], [d̪], [t̪͡s̪], and [d̪͡z̪] respectively) and /l/ and /n/ become denti-alveolar before a following dental consonant.[3]

Although denti-alveolar consonants are often described as dental, it is the rear-most point of contact that is most relevant, for this is what defines the maximum acoustic space of resonance and will give a consonant its characteristic sound.[4] In the case of French, the rear-most contact is alveolar or sometimes slightly pre-alveolar.
