Yogurt
Yogurt is another effective home remedy for canker sores. It works by restoring the balance of good bacteria in the mouth, which can help to speed up the healing process.
In addition, yogurt contains an enzyme that helps break down the proteins that trigger canker sores. To use yogurt to treat canker sores, apply some yogurt to the affected area and leave it for 10 to 15 minutes. Then, rinse it with warm water and repeat it every day until the sore has healed. You can also try eating yogurt regularly as a preventative measure. Again, the live and active cultures will help to keep your mouth healthy and free from infection.
Another method of using yogurt for canker sore treatment is by applying a small amount of yogurt to the affected area several times a day. You can also try swishing yogurt around your mouth for a few minutes before swallowing. Some people find this method particularly helpful in relieving pain associated with canker sores. If you prefer, you can also take probiotic supplements or eat foods that contain live bacteria, such as sauerkraut, kimchi, or kefir.
