Frequently Asked Questions

What is the buccal surface of a tooth?
The buccal surface of a tooth is the outer surface that faces the buccal mucosa, which is the inner lining of the cheek. The term is typically applied to posterior teeth such as premolars and molars, distinguishing this surface from the labial surface of front teeth that faces the lips.
Where is the buccal surface of a tooth located?
The buccal surface is located on the cheek-facing side of posterior teeth in both the upper and lower jaws. It is the outward-facing surface of premolars and molars, positioned adjacent to the buccal fat pad and cheek musculature.
What is the function of the buccal surface of a tooth?
The buccal surface is involved in chewing and food processing. It contacts food boluses during mastication and plays a role in the self-cleansing action of the cheeks. The cusps and ridges on the buccal surface of molars are particularly important for grinding food.
What conditions may affect the buccal surface of a tooth?
The buccal surface may be associated with cervical caries near the gumline, erosion from acidic foods, and abrasion from overzealous brushing. Buccal exostoses — bony outgrowths along the outer jaw — may also develop adjacent to this surface in some individuals.
How is the buccal surface of a tooth examined?
The buccal surface is examined by visual inspection with a dental mirror and explorer during clinical examination. The dentist assesses for signs of caries, erosion, recession, and calculus buildup, particularly along the cervical margin near the gumline.
