Canker sores without treatment usually go away on their own within 2 to 3 weeks.

You can try applying some orajel or other numbing agent to the canker sore inside your mouth to help it feel better and make it go away sooner.

Also you can get rid of a canker sore by either applying apple cider vinegar topically to the canker sore or gargling with apple cider vinegar to get rid of the canker sore.

If you can't get the canker sore to go away or it lasts longer than 3 weeks or a fever comes along with the canker sore then you need to see your doctor.
