Final answer:
The mandibular lateral incisor is wider mesiodistally, meaning from the midpoint of the mouth towards the back. The term 'faciolingual' describes the tooth's width from the cheek to the tongue side.
Step-by-step explanation:
The mandibular lateral incisor is a tooth located in the lower part of the mouth. When assessing its dimensions, the tooth is known to be wider mesiodistally rather than faciolingually. The terms faciolingual and mesiodistal refer to the dimensions of a tooth. Faciolingual describes the width of the tooth from the cheek (facial side) to the tongue (lingual side), whereas mesiodistal describes the width of a tooth from the midpoint of the mouth towards the back (distal side).
