Common Causes of Canker Sores
Canker sores are small ulcers that can occur anywhere in your mouth. They are not related to cold sores and can occur in anyone of any age. Although they can vary dramatically in size and even location, they have one thing in common: Canker sores hurt. There is no treatment for canker sores, but there are known risk factors that can increase your odds of getting one.
A virus causes cold sores, but the exact cause of cold sores is unknown. They are believed to be hereditary and are not contagious. Some scientists have linked canker sores to certain vitamin deficiencies and iron deficiency. Certain foods, spices and other oral irritants can increase your risk of developing canker sores. If you are prone to canker sores, an outbreak can also be triggered by any trauma to the mouth. Certain dental procedures, overly aggressive brushing or careless flossing are common causes. An accidental bite to the cheek or lip may cause a canker sore to erupt. Extreme emotional stress can also be responsible for a sudden eruption of canker sores.
Canker sores are self-limiting and will usually heal in a few days to a few weeks. Avoiding spicy or irritating foods, brushing and flossing gently and avoiding chewing gum can all reduce the pain associated with canker sores. If your sores are extremely large, spreading, last beyond three weeks, are associated with a fever or interfere with your ability to drink, contact Dr. Bijan Afar DDS, Los Angeles dentist, for further evaluation and treatment recommendations.
