Your doctor or dentist can diagnose a canker sore based on its appearance. Here's some information to help you get ready for your appointment.

Information to gather

Before your appointment make a list of:

• Your symptoms, including when they first started and how they may have changed or worsened over time
• All your medications, including over-the-counter medications, vitamins or other supplements, and their doses
• Any other medical conditions, to see if any relate to your symptoms
• Key personal information, including any recent changes or emotional stressors in your life
• Questions to ask your doctor or dentist to make your visit more efficient

Here are some basic questions to ask:

• Do I have a canker sore?
• If so, what factors may have contributed to its development? If not, what else could it be?
• Do I need any tests?
• What treatment approach do you recommend, if any?
• What self-care steps can I take to ease my symptoms?
• Is there anything I can do to speed up healing?
• How soon do you expect my symptoms will improve?
• Is there anything I can do to help prevent a recurrence?

Don't hesitate to ask any other questions during your appointment.
