Canker sores, also known as Aphthous Stomatitis, refer to small white-colored ulcers that appear on the tongue, the inside of the cheeks, and the lining of the lips. They appear as a small spot that is white or yellowish in color and may have a gray center. They are well defined by a red outline and are 3 to 5 mm in diameter. As per the National Institute of Dental and Craniofacial Research, these sores can affect any age group and can recur frequently. They are not contagious in nature.

The healing period of canker sores can range from 8 to 10 days, where the sore can be very painful for 3-4 days, especially during eating, drinking, or speaking.
