Ingredients to look for in Mouthwash for Canker sores – Buying Guide

While oral mouthwashes are a good way to ease canker sores, you should consider the ingredients of the mouthwash that you decide to get. Here are some things you should look out for.

Steroid Dexamethasone

If you are searching for a mouthwash to relieve canker sores, doctors will suggest getting one that has steroid dexamethasone. The steroid dexamethasone helps to relieve inflammation and pain thereby relieving canker sores. Hence, before getting the mouthwash, make sure to check for this ingredient.

Alcohol or None

While some believe that canker sores can be caused by alcohol, dental professionals talk about the importance of alcohol as an antiseptic ingredient in mouthwashes. So if you plan to get a mouthwash, it’s best to get one that has alcohol because doctors recommend it for relief from mouth sores.


Some mouthwashes may contain fluoride. The benefits of having fluoride in your mouthwash seem to be contested. If you do not have fluoride in the water you use, having a little of it in a mouthwash won’t make a difference. Fluoride is good for strengthening and protecting the enamel, and may not have much to do with your canker sores. So, the choice of using a fluoride mouthwash is entirely yours.
