Mouth Sores

Sores or irritations can develop in and around the mouth. Fortunately, they usually heal on their own within a week or two. Mouth sores come in several different varieties and can have any number of causes, such as:

  • Infections from bacteria, viruses or fungus

  • Irritation from a loose orthodontic wire, an ill-fitting denture, or a sharp edge from a broken tooth or filling.

  • The symptom of a disease or disorder.

If your mouth sores lasts for more than two weeks, you should have your dentist examine it. Your dentist can prescribe medication to help you treat it. In the mean time you should:

  • gargle with salt water

  • avoid hot, spicy, salty, citrus-based, and high-sugar foods

  • avoid tobacco and alcohol

  • avoid squeezing or picking at the sores

  • take a pain medication, such as acetaminophen (Tylenol)
