Can Mouthwash Cause Canker Sores?

In a word, yes!  Some people are naturally prone to canker sores.  They can be caused by a variety of things, such as citrus fruit, pineapple, some nuts and even eggs, believe it or not!  But if you are experiencing canker sores and you don't usually get them, check your daily mouthwash.  An active ingredient in many mouthwashes called sodium lauryl sulfate is a known irritant and could be the nasty culprit behind the sores.  Additionally, mouthwash containing alcohol is another factor.  Alcohol typically causes a burning sensation in the mouth, which can cause canker sores or irritate them if they are already present.  A better alternative is to rinse with mild (MILD) salt water or find a sulfate and alcohol free mouthwash for everyday use.  Your dental provider may have some good suggestions for you!
