齿音（或舌尖前音、常被称为齿间音、舌齿音）是舌尖音的一种。发音时，舌尖顶住上门牙。因为另一个可能的发音位置是发音时舌尖在上门牙和下门牙之间。

齿擦音（国际音标为θ和ð）出现在英语、冰岛语等语言中。中文等语言的s是齿龈擦音而不是齿擦音。

齿塞音、鼻音、边音的国际音标符号和齿龈音的符号一样，只是在辅音下加一个形如“横卧的左方括号”（英语称bridge）的符号：

在古汉语中，齿塞音被称为“舌头音”，而齿擦音和齿塞擦音为“齿头音”。

A dental consonant is a consonant articulated with the tongue against the upper teeth, such as /t/, /d/, /n/, and /l/ 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).
