In phonetics and phonology, a dental stop is a type of consonantal sound, made with the tongue in contact with the upper teeth (hence dental), held tightly enough to block the passage of air (hence a stop consonant).[1]

Dental and alveolar stops are often conflated.[2] Acoustically, the two types of sounds are similar, and it is rare for a language to have both types. The International Phonetic Alphabet does not provide separate symbols for dental stops, but simply uses the diacritic U+032A ◌̪ COMBINING BRIDGE BELOW attached to the corresponding alveolar symbol.[3] As a result, it is common for researchers working in the majority of languages with only one type or the other to simply use the alveolar symbols indifferently for both types, unless they specifically want to call attention to the distinction.

The most common sounds are the stops [t̪] and [d̪]. More generally, several kinds are distinguished:[4]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
