Dental consonants

A dental consonant is a consonant articulated with the tongue against the upper teeth, such as, , , and in some languages. Dentals are primarily distinguished from sounds in which contact is made with the tongue and the gum ridge, as in English (see Alveolar consonant), due to the acoustic similarity of the sounds and the fact that in the Roman alphabet they are generally written using the same symbols (t, d, n, and so on).

In the International Phonetic Alphabet, the diacritic for dental consonant is

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

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 also exists in these languages, but is quite alveolar and apical in articulation. To the Indian speaker, the alveolar and  of English sound more like the corresponding retroflex consonants of his own language than like the dentals.

Spanish and  are laminal denti-alveolar while  and  are prototypically alveolar but assimilate to the place of articulation of a following consonant. Likewise, Italian, , , are denti-alveolar (, , , and  respectively) and  and  become denti-alveolar before a following dental consonant.

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. In the case of French, the rear-most contact is alveolar or sometimes slightly pre-alveolar.
