Nothing is going to beat brushing and flossing properly, but mouthrinses can often supplement your specific needs. If you are at high risk of tooth decay, gum disease or have had an extraction/oral surgery, you may consider using a mouth rinse. In these cases you should choose one that suits the required purpose. Generally look for the ADA symbol to ensure it is anti-bacterial which may help reduce gingivitis. In other cases our clinicians can help advising on specifics.
