Mouthwash

Mouthwash is usually not required as part of a standard oral hygiene routine, provided mechanical cleaning (toothbrushing, interdental cleaning) is performed properly. Mouthwash should not be used as substitute for proper mechanical teeth cleaning.

Fluoride-containing mouthwashes can be used as an additional source of fluoride for people at high risk of dental caries on the recommendation of a dentist (see Fluoride).

Mouthwash that inhibits plaque formation (eg chlorhexidine) can be used for a short duration in addition to mechanical tooth cleaning, usually when pain associated with periodontal disease restricts mechanical cleaning (see Management of necrotising gingivitis and Gingivitis).

Alcohol-containing mouthwashes may be associated with oral cancer and are not recommended. See here for further information on mouthwashes.
