1 The two main functions of the mouth are eating and speaking. 2  The faceâs trigeminal nerve provides sensation (feeling) and helps us to bite, chew and swallow.  Some disorders of the mouth include infections, ulcers, cancer, cleft palate, dry mouth syndrome, dental caries and speech problems such as lisping.
Problems of the Mouth and Teeth A smile is the facial expression that most engages others. With the help of the teeth â which provide structural support for the face muscles â the mouth also forms a frown and other expressions that show on your face. The mouth also plays a key role in the digestive system, but it does much more than get digestion started. The mouth â especially the teeth, lips, and tongue â is essential for speech. The tongue, which allows us to taste, also helps form words when we speak. The lips that line the outside of the mouth both help hold food in while we chew and pronounce words when we talk.
