While canker sores may not be serious to your health, they are irritating and can cause you to suffer significant discomfort when they appear. Although the ulcers are small and shallow, they can appear unexpectedly on the gums and inner lips, where they linger for days. Avoiding these five common triggers for canker sores can largely help you prevent the ulcers from occurring:

– Stress, which promotes the development of canker sores by weakening the immune system
– Tissue injury from biting your cheek or lip and causing cuts or scrapes that turn into canker sores
– Acidic foods such as tomatoes, pineapples, lemons, strawberries, and sour candies that irritate the mouth with their high acid concentration
– Dental appliances such as dentures and braces that don’t fit well and cause friction and oral tissue irritation
– Sickness and infection that cause canker sores by taxing the body

Knowing what causes canker sores is important if you wish to avoid the triggers. Cut out problematic foods from your diet as much as you can, speak with your orthodontist if your braces are irritating and need adjustment or coat them with dental wax. You can also find ways to lower your stress levels during the day. If canker sores are still a problem, you may find relief if you brush with a sodium lauryl sulfate-free toothpaste and soft-bristled toothbrush and use a salt water rinse.
