  1. Brush your teeth, and rinse your mouth

    To speed the healing process, brush your teeth regularly with a soft toothbrush to reduce bacteria in the mouth. After brushing, rinse your mouth with baking soda water. Mix 1 teaspoon of baking soda in 1/2 a cup warm water, and swish it around in your mouth.

  2. Cover the canker sore with a baking soda paste

    Mix baking soda with a small amount of water to make a paste. Dab the baking soda paste on the canker sore, and allow it to dry. Wash off the dry baking soda with cool water, and gently press ice on the canker sore to shrink it.

  3. Apply an over-the-counter numbing agent

    While the canker sore is healing, apply an over-the-counter numbing agent to alleviate pain and discomfort. Follow the specific product directions for using the numbing agent. Avoid eating spicy or acidic foods, as these may irritate the canker sore and make it worse.
