Stomatitis, a general term for an inflamed and sore mouth, can disrupt a person's ability to eat, talk, and sleep. Stomatitis can occur anywhere in the mouth, including the inside of the cheeks, gums, tongue, lips, and palate.
Types of Stomatitis
Types of stomatitis include:
- Canker sore: A canker sore, also known as an aphthous ulcer, is a single pale or yellow ulcer with a red outer ring or a cluster of such ulcers in the mouth, usually on the cheeks, tongue, or inside the lip.
- Cold sores: Also called fever blisters, cold sores are fluid-filled sores that occur on or around the lips. They rarely form on the gums or the roof of the mouth. Cold sores later crust over with a scab and are usually associated with tingling, tenderness, or burning before the actual sores appear.
- Mouth irritation. The irritation can be caused by:
- Biting your cheek, tongue, or lip
- Wearing braces or another type of dental apparatus, or having a sharp, broken tooth
- Chewing tobacco
- Burning one's mouth from hot food or drinks
- Having gum disease (gingivitis) or other type of mouth infection
- Having hypersensitivity to certain things, such as foods or medicines
- Having certain autoimmune diseases affecting the mucosal lining of the mouth, such as lupus, Crohn's disease, or Behcet's disease
- Taking certain drugs such as chemotherapy, antibiotics, medications used for rheumatoid arthritis, or epilepsy medications
- Receiving radiation as part of cancer treatment

Causes of Stomatitis: Canker Sores and Cold Sores
Nobody knows what exactly causes canker sores, but many things may contribute to their development, such as certain medications, trauma to the mouth, poor nutrition, stress, bacteria or viruses, lack of sleep, sudden weight loss, and certain foods such as potatoes, citrus fruits, coffee, chocolate, cheese, and nuts.
Canker sores may also be related to a temporarily reduced immune system because of a cold or flu, hormonal changes, or low levels of vitamin B12 or folate. Even biting the inside of the cheek or chewing a sharp piece of food can trigger a canker sore.
