Mouth rinse use: How often you should use listerine/other mouth rinse depends on what you want to achieve by use. If it is simply to add more thoroughness to your home care, 1-3 times daily right after brushing is an expected maximum. If you use a mouth rinse that kills oral bacteria, this means that good ones are killed also. A healthy mouth needs a healthy colony of good bacteria. Be cautious on excessive use.
