Do you ever get canker sores? Also known as mouth ulcers, these are little crater-like welts that can appear on the inner lining of the mouth, tongue or lips. Although usually harmless they aren’t too fun and can cause pain or irritation. In this article we look at the causes of canker sores and importantly, how to relieve canker sores.

Causes of Canker Sores

The science around canker sore causes isn’t 100% clear. There are a few things that are thought to trigger these little outbursts, but in reality why they come and go when they do changes from person to person. If you find yourself affected here are a few things to watch out for in daily life:

  • Particular food groups: There are a few different types of foods that may cause mouth ulcers. These include rough edged foods, chocolate, wheat, spicy or very hot foods and citric acid (as found in lemons, limes, oranges etc)
  • Mouth irritation: Think poorly fitting dentures or a defective filling that rubs against the side of the cheek. Accidentally biting your cheek can have a similar effect
  • Certain types of toothpaste: Some toothpastes contain sodium lauryl sulphate and experts believe this could be one cause of canker sores
  • Stress and anxiety: Health professionals also think stress and anxiety might play a role in causing this problem
  • Hormonal changes: Having more or less of certain hormones can be one cause of canker sores on the tongue, mouth or lips. Women sometimes develop mouth ulcers around the time of their monthly menstruation and are more susceptible during pregnancy
  • Stopping smoking: While quitting smoking is great for your health, it can have this unfortunate side effect. If mouth ulcers are making it difficult to give up cigarettes talk to a healthcare professional for advice.
