Many people wonder when to use mouthwash for the best results. The most effective time to use mouthwash is after eating or to freshen your breath throughout the day. However, if you’re using an antibacterial mouthwash for gum health, it may be more beneficial to use it after brushing and flossing.

Using a mouthwash for whitening isn’t necessary; however, it can be a great addition to your oral care routine. Choose a mouthwash that contains fluoride, which can help to reduce plaque bacteria and prevent tooth decay.

A fluoride mouthwash can prevent stains on teeth, especially if it’s a whitening mouthwash. However, many antibacterial mouthwashes used for gum disease or infections, like chlorhexidine, contain ingredients that can cause temporary staining.
