The development of a canker sore begins with a tingling, burning sensation. The sore grows as a bump in your mouth, which then ruptures within a day. This leaves a white or gray open wound surrounded by a red border. Here are a few ways you can treat these canker sores.

Most of the time a canker sore will heal on its own in one to two weeks time. However, they can still feel painful during this period. You can relieve discomfort by:

  • Applying a anesthetic ointment
  • Rubbing ice chips gently against the sores
  • Avoiding hot, spicy, acidic, rough-textured foods
  • Using an antimicrobial mouthwash
  • Avoiding or treating the factors that trigger canker sores (such as stress, food allergies, fatigue, a poor diet, injury to oral tissue, etc.)

Also don’t forget to continue brushing and flossing your teeth. Be careful around the ulcer and make sure you use a soft-bristle toothbrush to avoid triggering the development of more sores.

Usually canker sores aren’t a serious problem and don’t require treatment from a medical professional. However, you should see a dentist or physician if you show symptoms such as:

  • Large canker sores
  • Severe pain
  • Sores that extend onto the lips
  • Reoccurring sores
  • Sores that heal slowly
  • Sores accompanied by fever

Depending on the severity of the canker sore, your dentist or physician will recommend the best treatment plan which may include:

  • A mouthwash containing lidocaine or dexamethasone
  • Antibiotics and oral bandages (to reduce secondary infection)
  • Cauterizing the sore
  • Taking an oral steroid medication (if no other treatment options work)
