How to Heal an Open Sore Inside of the Mouth

An open sore inside of your mouth is most likely the result of a burst canker sore. Canker sores can appear during times of stress or hormone imbalance. They can also appear due to the sodium lauryl sulfate in your toothpaste or mouthwash. Because open sores can be a big source of pain and irritation, it's important to heal it quickly.
