Recurrent canker sores may be the result of nutritional deficiencies. A patient who has regular problems with canker sores should have blood tests to determine possible vitamin deficiencies, and to determine potential problems with allergies. It may be helpful to keep a "food diary" to determine potential allergies or food irritants.
Other preventive tactics include:
- Avoid toothpastes and mouthwashes containing SLS (sodium lauryl sulfate)
- Include yogurt and other cultured, soured dairy products in your diet.
- Avoid tobacco, chewing gum, and lozenges.
- Avoid citrus fruits.
- Eat salads and raw onions.
- Do not take iron supplements unless prescribed by a doctor.
Diet and canker sores.
What food allergies or reactions may cause canker sores?
What food allergies or reactions may cause canker sores?
A study conducted in Turkey suggested that wheat, oranges, tomatoes, chocolate, nuts, eggplant, tea and cola may trigger aphthous ulcers. [Oral Surg. 1984:57, pp.504-507] When food triggers are identified and eliminated from the diet, as many as 50% of those suffering from recurrent canker sores notice dramatic improvement.
Anecdotal evidence suggests that diets high in sugar, citrus, and cereal grains may trigger canker sores. By avoiding these foods, the patient can see for himself whether they may be triggers in his case.
Adequate zinc and folic acid intake are essential for rapid healing. In addition, nutrients such as DGL licorice, goldenseal, and pau d'arco tea have a tradition of helping heal aphthous ulcers.
