What’s the White Stuff in a Canker Sore?
Canker sores, also known as aphthous ulcers, are small, painful ulcers that can develop in the mouth. They are caused by a variety of factors, including stress, hormonal changes, and certain foods. The white stuff in a canker sore is actually a protective layer of fibrin, a protein that helps to form a scab over the sore. This layer helps to protect the sore from further irritation and infection.
Canker sores are not contagious and typically heal within a week or two. However, if a canker sore is particularly large or painful, it may take longer to heal. If you have a canker sore that does not heal within a few weeks, or if you have any other questions about canker sores, be sure to see your doctor.
Types of Canker Sores
There are three main types of canker sores: minor, major, and herpetiform. Minor canker sores are the most common type. They are small, oval-shaped, and usually heal within a week or two. Major canker sores are larger and deeper than minor canker sores. They can take several weeks to heal and may leave a scar. Herpetiform canker sores are the least common type. They are small, round, and cluster together. Herpetiform canker sores can be very painful and may take several weeks to heal.
