Can you tell me how i could tell if my canker sore is infected?
A doctor has provided 1 answer
Most don't: The mouth is pretty good at fighting off infections and most canker sores don't get infected. But if it is swollen and hot feeling, or has any exudate, you better see a dentist. Just because it has a whitish appearance to it, doesn't mean it's infected.
