Canker sores are small, white, shallow ulcers that appear on the lower lip and even on the outer portion of the lip, explains WebMD. Simple canker sores typically appear three or four times a year in individuals between 10 and 20. The sores last approximately a week and can make talking and eating uncomfortable when the canker sore rubs against the top lip or comes in contact with food. Canker sores usually heal without treatment; however, if they are large and painful, a physician may prescribe a corticosteroid ointment or antimicrobial mouth rinse.

A mucocele, often known as a cyst, affects the lower lips, gums, roof of the mouth and underneath the tongue. The soft, round, dome-shaped, white cysts are typically painless, according to WebMD. The cyst usually has a pearl-colored surface and is 2 to 10 millimeters in diameter on the lower lip. Mucoceles does not usually require treatment as it resolves on its own over time; however, when the cyst enlarges, physicians or dentists may opt to remove the gland with a laser or scalpel to minimize discomfort from the cyst's size.
