The mental nerve (branch of the inferior alveolar nerve from mandibular nerve) typically divides into three main branches after emerging from the mental foramen:
1.Inferior labial branch
→ Supplies the skin and mucous membrane of the lower lip
2.Mental (cutaneous) branch
→ Supplies the skin of the chin
3.Gingival branch
→ Supplies the gingiva (labial mucosa) of mandibular anterior teeth
