This homemade alum mouth rinse is good way to use alum to get rid of mouth sores. To make the rinse, powder alum in a mortar and pestle. Boil water in a pan along with little salt, once the salt has dissolved remove from the heat and stir in the alum powder.

Salt is also very effective in treating canker sores and this mouth rinse can be safely used by both young and old. If you are using the raw alum powder, make sure not to swallow it while applying over the canker sore and use only a tiny bit.
