Final answer:
The five surfaces on an ANTERIOR tooth are the facial (or labial/buccal), lingual, incisal, mesial, and distal surfaces, each serving its own purpose in food consumption.
Step-by-step explanation:
The ANTERIOR teeth, mainly consisting of the incisors and canines, have five different surfaces that are named based on their location and function:
- Facial Surface: The surface facing towards the cheeks or lips. On the front teeth, or incisors, this is often referred to as the labial surface, while on canines it is sometimes called the buccal surface.
- Lingual Surface: This surface faces the tongue.
- Incisal Edge: Found on the incisors and canines, this is the biting edge of the tooth.
- Mesial Surface: The surface of the tooth that is closest to the midline of the face.
- Distal Surface: The surface facing away from the midline of the face, towards the back of the mouth.
These surfaces play vital roles in the specific functions of the ANTERIOR teeth, from biting into food with the help of sharp incisal edges of incisors to tearing food with the pointed cusp of canines.
