Tips for Managing Canker Sores by Livermore Dentist

Managing Canker Sores

Canker sores are blisters that form inside of the mouth. They tend to be painful, vary in size, and can form on the tongue, throat, inner cheeks, and gums. The reason canker sores form is unknown, though, there are a few different things that are known to contribute to the development of the sores. These sores can form when the tissue inside of the mouth is irritated or if the body has been stressed. There are also certain acidic foods that may not necessarily cause the sores but can irritate them. These are mainly different sour fruits, lemons. There are also more complex canker sores that may appear when a person has an immune system disorder, nutritional imbalances, and can be a symptom of certain diseases.

  • A painful sore inside your mouth which can appear on or under the tongue, at the base of the gums, inside the cheek or lip or on the soft palate
  • Tingling before the ulcer appears

Canker sores can really hurt at first, which should decrease after the first few days, and the ulcer itself should heal completely without treatment in about one to two weeks. If it persists, is large, still very painful, or if the sores seem to be spreading, you should visit your dentist, who may recommend a corticosteroid ointment or antimicrobial mouth rinse. There are also plenty of over-the-counter solutions that can help reduce pain and irritation. Although they are incurable, you may be able to prevent canker sores and reduce their frequency by following these recommendations from

  • Cut back on chewing gum, which can cause irritation
  • Lower your intake of citrus fruits, acidic vegetables, and spicy foods – all of which can irritate the inside of your mouth
  • Choose a soft-bristled brush for cleaning your teeth
  • Brush after meals and floss daily
