Canker sores are very common. These painful sores usually appear on the tongue, gums or the inside walls of the cheeks. When you have this oral condition, it can be very difficult to chew, eat or speak.

You can easily tell if youíre about to have one because youíll feel a burning or tingling sensation in your mouth, particularly in the spot where the canker sores are about to appear. As it matures, these oral sores will have a red edge, resulting from its inflamed state. Most canker sores appear as round with a white or greyish hue in its middle. In severe cases, canker sores can bring about physical sluggishness, swelling in the lymph nodes and fever.

The common causes of canker sores include stress and trauma to the soft tissues in the mouth. Nutritional deficiencies in iron, folic acid, zinc and vitamin B-complex can also result in having these sores. Canker sores may also appear as a result in having a weakened immune system.

Generally canker sores go away after a week or two without need of treatment; the pain, on the other hand, will subside in just a few days from the time it was first felt. In cases where treatment is required, dental lasers offer an almost-immediate relief.

Unfortunately canker sores are not something that can be prevented. Although you can minimize the likelihood of having them. To reduce the risk of having these painful sores, here are a couple of tips you can use:

  • Chewing sugarless gum can help you avoid irritation
  • Cut down on citric fruits and veggies
  • Lay off the spicy food once in a while
  • Use a soft-bristled toothbrush
  • Avoid ill-fitting dental braces or dentures


If youíre having unusually large sores (as when they last for more than 3 weeks or spreading uncontrollably inside the mouth), speak with your dentist. When there is intolerable pain or if accompanied by fever, seek medical help immediately.


Patient Reviews

I actually enjoy going to the dentist
I actually enjoy going to the dentist! I have never had a bad experience at Dr Sandahls office, and I trust him completely with my oral care. He actually stayed late to accommodate my schedule today. I would highly recommend him to anyone I know, and anyone I don't know. You won't be disappointed with the service you will receive.
