How to Cure Mouth Ulcers in Minutes and Naturally

Baking soda . Like salt, baking soda is an effective natural antiseptic that can help us heal canker sores quickly. As with salt, rinse with a solution of water and baking soda.

Yogurt . Contains large amounts of beneficial bacteria for our body, which will help us to slightly change the pH of the mouth making it difficult for bacteria to live. Eat at least one yogurt a day.

Hydrogen peroxide . Soak a cotton ball in hydrogen peroxide and apply it directly to the canker sore for a few minutes. Repeat 2 or 3 times a day.
