The function of this premolar is to assist the mandibular first molar during mastication. Mandibular second premolars have three cusps. There is one large cusp on the buccal side of the tooth. The lingual cusps are well developed and functional, which means the cusps assist during chewing.
The side of a tooth that is adjacent to (or the direction toward) the inside of the cheeks and lips, as opposed to lingual or palatal (both oral), which refer to the side of a tooth adjacent to (or the direction toward) the tongue or palate, respectively, of the oral cavity. Vestibular includes both buccal and labial.

The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
The buccal raphe, which is on the cheek and evidence of the fusion of the maxillary and mandibular processes; The lingual raphe on the tongue. Obvious physical evidence of the lingual raphe includes the frenulum (also called the frenum), or band of mucous membrane that is visible under the tongue attaching it to the floor of the mouth. If this ...
