HEALTH INFORMATION

Most canker sores don't hurt as much after the first few days, but it may take 2 weeks for the sore to heal. While you're waiting, you'll want to be careful when eating and brushing your teeth. Scraping the sore can make it hurt worse. You might need some medication to dull the pain. Your mom or dad can ask your doctor about which one is best for you.
If your canker sore is large, lasts longer than a week, or is keeping you from eating, you should see your doctor so he or she can check it out.
