Mouthwash

A solution for rinsing the mouth. Many only leave the mouth feeling fresh and remove loose food debris from the teeth. Some, such as those containing hydrogen peroxide, can help to clean the teeth if the gums are too tender for proper toothbrushing, as in some types of gingivitis. Those containing chlorhexidine are effective against plaque when routine dental hygiene is impossible. Fluoride mouthwashes help to prevent tooth decay (see caries, dental), and a mouthwash of warm salt water can help to ease painful inflammation caused by tooth disorders. Antiseptic mouthwashes intended to combat halitosis are usually ineffective because they do not treat the cause of the problem.
