Mouthwash, also known as an oral rinse, is a liquid solution used for oral hygiene. It is typically used after brushing and flossing to further clean the mouth and freshen breath. Mouthwash often contains antiseptic ingredients that help kill bacteria and reduce plaque buildup, promoting healthier gums and teeth. It can also provide temporary relief from bad breath and leave a pleasant taste in the mouth.
