常见问题

What is the labial surface of a tooth?
The labial surface of a tooth is the outer surface of front teeth — incisors and canines — that faces the lips. It is a specific type of facial surface, distinguished from the buccal surface of posterior teeth. The labial surface is the most visible part of the anterior dentition.
Where is the labial surface of a tooth located?
The labial surface is located on the lip-facing side of the upper and lower incisors and canines. These front teeth are positioned at the front of the dental arch, making the labial surface directly visible when the mouth is open or when smiling.
What is the function of the labial surface of a tooth?
The labial surface contributes significantly to dental aesthetics and the appearance of the smile. It also interacts with the lips during speech, particularly for the production of labiodental sounds. During biting, the labial contour of incisors guides food into the mouth.
What conditions may affect the labial surface of a tooth?
The labial surface may be associated with enamel staining from beverages, tobacco, or medications, as well as surface erosion from acidic foods. Developmental enamel defects such as white spot lesions may appear on labial surfaces. It is also a common site for dental bonding and veneers.
How is the labial surface of a tooth examined?
The labial surface is directly visible during visual examination and is assessed for color changes, cracks, erosion patterns, and developmental anomalies. Dental photography is often used to document labial surface appearance for cosmetic treatment planning.
