Canker Sores

Have you ever had one of those annoying little white dots on your tongue or tissue?  It feels sore and you just can’t seem to stop touching it with your teeth.  You most likely have a canker sore.  Canker sores are small, painful ulcers in the mouth. They may be caused by stress, injury, irritating foods, nutritional problems, and an impaired immune system. Sometimes a sharp tooth surface or dental appliance, such as braces or ill-fitting dentures, might also trigger a canker sore.

There is no cure for canker sores however, there are prescription medications that help alleviate the length or frequency of occurrence.  Other options for helping to reduce how often you get them are to avoid foods that irritate your mouth. Spicy foods, acidic foods like pickles, and citrus fruits and juices can cause irritation as well as gum chewing.

To ease the discomfort try eating a bland diet such as the following:

  • low-fat milk and other dairy foods
  • cooked, canned and frozen vegetables
  • mashed potatoes
  • applesauce
  • hot cereals like oatmeal and cream of wheat
  • soft cooked and shredded chicken, beef and pork
  • creamy-style peanut butter
  • pudding and custard
  • scrambled or fried eggs
  • tofu
  • soup

It may help to drink through a straw. In addition, brush with a soft-bristled brush after meals and floss daily, to keep your mouth free of foods that may trigger a canker sore.
