Key Takeaways
  1. Despite the fact they may appear similar, canker sores are not as severe as cold sores and are not contagious. Cold sores are a symptom of the herpes simplex virus (HSV-1), whereas there is no definitive cause behind canker sores.
  2. Canker sores should heal over time on their own, however they can be painful. Taking pain medication, eating soft food and being gentle when cleaning your teeth and mouth will help not to agitate them.
  3. Canker sores on tonsils are not as common as contracting them in the mouth or lips, however they also do heal on their own still. Using a gentle mouthwash will help keep your mouth and throat clean and will not further inflame them.
  4. Adopting and maintaining a healthy lifestyle and optimum oral care routine will help prevent contracting canker sores. This includes regular dentist check-ups as well.
