What Causes Canker Sores?
Canker sores are very unpredictable and quite uncomfortable for many who suffer from them. Canker sores (apthous ulcers) are white sores, not blisters, that typically occur inside the cheeks, lips, and possibly on the gum tissues.
Most canker sores range in size from smallish dots to large coin-sized ulcerations. They can be pretty painful, make speaking, eating, or even a simple smile difficult, and may take 1-2 weeks to heal.
Researchers have studied canker sores for years, but the exact cause remains a mystery. There have been possible links to a patient’s genetic background, increased stress, or even minor oral trauma.

Tips To Avoid Canker Sores
Maintain Proper Nutrition.
It is essential to maintain proper nutrition. This is to ensure you are consuming the right mix of vitamins and minerals to keep your body healthy. Research has shown nutritional deficiencies can cause mouth ulcers. Researchers have shown that zinc, B12, iron, l-lysine, and folic acid can all be very helpful in preventing the development of canker sores.
Avoid Certain Foods.
If you are experiencing a canker sore outbreak, you should watch what you eat. Acidic foods and drinks (such as lemonade or orange juice) can inflame and irritate the painful canker sores and prolong healing. Consuming chocolate is a known trigger for apthous ulcers.
Change Dental Hygiene Products.
The bubbling agent used in toothpaste can be an irritant to some patients’ oral tissues. If you notice sloughing tissues, red or irritated tissue, and experience frequent canker sores, you may want to remove regular toothpaste from your dental hygiene routine.
You may want to experiment with some new dental hygiene products that are gentler in your mouth. There are specialized canker sore toothpaste specially formulated not to irritate the mouth. These kinds of toothpaste are sodium lauryl sulfate-free (SLS).
Sodium lauryl sulfate is generally used in toothpaste to produce that foaming action when brushing. It is believed that changing to an SLS-free toothpaste will reduce the incidence of canker sores.
Rises in hormones during the menstrual cycle, menopause, pregnancy can also trigger a patient to develop canker sores.
Certain medications can trigger apthous ulcers. These medications include Nicorandil, a medicine used in patients with angina, antihypertensives, sulfa drugs, and immunosuppressants.
