DIY Remedies for Canker Sores

Canker sores are small ulcers in your mouth that can be very uncomfortable. They are not contagious and we are not sure what causes them.

We do know that they tend to show up when someone has been ill or under stress. Other possible triggers are acidic foods or abrasion caused by braces or dental appliances. Some people report that their outbreaks seem to be related to sodium lauryl sulfate, which is a common ingredient in toothpaste. You can find SLS free toothpastes online or at health food stores.

Canker sores usually heal on their own, but it is important to see a dentist if your sores are very large, spreading, or last more than 3 weeks.

If you have a fever or other signs of illness, see your medical doctor as these sores may be a sign of a health concern that needs attention.

You may also want to try these remedies that can help you feel more comfortable:

  • Rinse your mouth with a mixture of 1 tsp. baking soda and 1/2 cup warm water several times a day.
  • Put a dab of milk of magnesia directly on the sore.
  • Make a paste of baking soda and a small amount of water to cover it.
  • Try over the counter medications or gels that relieve pain.
  • Avoid spicy, salty, or acidic foods.
  • Dab aloe vera gel on it.
  • Sip chamomile tea with honey.
  • Ice, but be sure the ice has started to melt before placing it on the sore.
