According to the American Dental Association, some mouthwashes do more than leave breath smelling minty; they contain antiseptic agents, such as cetylpyridinium chloride to reduce plaque and prevent gingivitis, which can also cause bad breath. If mouthwash makes your tongue ad cheeks burn, switch to an alcohol-free version or dilute it with a little water. It might be less effective but you’ll still get benefits.
Good to Know: At bedtime, using mouthwash after brushing your teeth and tongue and flossing can help prevent morning breath. Be sure to gargle for at least 30 seconds to wipe out bacteria lurking in your throat and on the back of your tongue.
