The Short Answer

It doesn't cure them per-say. But the canker sores are typically infested with bacteria that like acidic environments. Likewise, the pain receptors exposed by the sore will react from acidic things. Baking soda is a basic compound, which means it will neutralize acid, which may both help with killing off bacteria keeping the wound infected, and more immediately, remove the stinging pain every time you poke at the sore (until your saliva eventually lowers the pH back down). You can get the same effect by chewing up a Tums tablet (calcium tablet) in your mouth and swishing it around over the wound. It might sting for a second, but then pick and prod at it all you want – you won't get that sharp shooting pain.
