How to Use Alum for Canker Sores - Best Home Remedy!



Canker sores are mouth ulcers that are white or yellow in color surrounded by red area. Canker sores are very painful and make eating, especially spicy foods next to impossible. The reason we get canker sores can be due to a variety of reasons ranging from low immunity, stress, eating certain foods and even braces can trigger canker sores. There is a good home remedy for canker sores. It is alum, the same alum that men have been using for their shave for centuries. Surprisingly alum treats a wide variety of diseases and I always have a block of it at home. Usually for canker sores, a small piece of alum is powdered and then a pinch of  that alum powder is pressed over the canker sore. It stings for a while, but by the next day, usually the person is relieved of canker sores. But many don't like to use the alum powder as such and young children will find it hard to bear the burn caused due to alum powder. 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. Once the alum has dissolved, strain and use it as a mouth rinse at least 2 to 3 times a day. 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.


1. This is alum and we get it in blocks.

2. Take a small piece of alum and powder it in a mortar and pestle to a fine powder.

3. Boil water along with little crystal salt. Once the salt has dissolved, switch off the flame. Stir in the alum powder.

4. Once the alum powder has dissolved, strain. Let it come to lukewarm temperature, before using it as a mouth rinse 2 to 3 times a day.

  • Use crystal salt, not the powdered salt.
  • If you can bear the sting, then applying the powder directly on the canker sore is even more effective.
  • When using the rinse, swish around your mouth and make sure that the area where the canker sore is rinsed.
