mouthwash

A fluoride mouth rinse, used alongside regular brushing and flossing, can help prevent tooth decay. Mouthwashes containing chlorhexidine are used in the treatment and prevention of gum disease but may stain teeth and should not usually be used for more than 10 consecutive days, unless advised by your dentist or hygenist.

Many mouthwashes may contain alcohol, which is potentially counter-productive as it can actually dry the mouth. Some mouthwashes may be of limited value and are often used to try and freshen bad breath - if you have constant unpleasant mouth odour, it is advisable to visit your dentist.
