The primary function of teeth is the chewing to facilitate predigestion and thus constitute the first step of digestion. But they also play a role in swallowing and the phonation.

In swallowing, they allow the tongue to “take hold” to push food towards the stomach.

In phonation, they allow, always in concert with the tongue, but also with the palate and the lips to modify the sounds which come out of the mouth, what are called, phonemes.

Finally, the teeth also participate in thefacial aesthetics and their good health contributes to the beauty and radiance of an individual.
