The use of a fluoride-containing mouthwash is excellent to give you a fresh feeling and strengthen your teeth. Try to use an alcohol free mouthwash if possible. Mouthwashes which contain alcohol can dry out the lining of your mouth and decrease saliva flow. Both of these symptoms can contribute to increased bacterial growth and lessen the mouth’s natural defenses.
You should swish with mouthwash for 30 seconds, twice a day, before spitting the product out.
