Mouthwashes are liquid solutions used to rinse the mouth, helping to reduce oral bacteria and freshen breath. They often contain ingredients like fluoride to strengthen teeth, antiseptics to kill germs, and flavoring agents for a pleasant taste. Mouthwashes can be used as part of a daily oral hygiene routine, alongside brushing and flossing. There are different types of mouthwashes available, including those for general use, therapeutic mouthwashes for specific dental issues, and cosmetic mouthwashes that primarily focus on breath freshening. It's important to choose a mouthwash that meets individual needs and to follow the instructions for use.
