Lifestyle and home remedies
By Mayo Clinic staffTo relieve pain and speed healing:
- Rinse your mouth. Use salt water; baking soda (dissolve 1 teaspoon of soda in 1/2 cup warm water); hydrogen peroxide diluted by half with water; or a mixture of 1 part diphenhydramine (Benadryl) to either 1 part bismuth subsalicylate (Kaopectate) or 1 part simethicone (Maalox). Be sure to spit out the mixtures after rinsing.
- Cover lesions with a paste made of baking soda.
- Try over-the-counter products that contain a numbing agent, such as Anbesol and Orajel.
- Avoid abrasive, acidic or spicy foods that can cause further irritation and pain.
- Apply ice to your canker sores or allow ice chips to slowly dissolve over the sores.
- Brush your teeth gently, using a soft brush and toothpaste without foaming agents, such as TheraBreath.
- Dab a small amount of milk of magnesia on your canker sore a few times a day. This can ease the pain and may help the sore heal more quickly.
