Where do i go to find most common at home remedies for canker sores?

Canker Sores: The exact cause of most canker sores is unknown. Stress or tissue injury is thought to be the cause of simple canker sores. Certain foods -- including citrus or acidic fruits and vegetables (such as lemons, oranges, pineapples, apples, figs, tomatoes, and strawberries) - can trigger a canker sore or make the problem worse. It usually resolves in a week or 2 but minimizing irritation can help.
