The role of mouth rinse as part of a patient’s oral care routine

Within the context of mechanical plaque removal, there are a number of oral hygiene and health issues that the use of a mouth rinse can potentially help to address.

The use of an effective mouth rinse has proven ability to reduce plaque accumulation,1 with the ability to penetrate the biofilm an important factor in determining the efficacy of a particular product.2 Use of a mouth rinse has also been shown to kill the bacteria associated with gingivitis and periodontal disease.3

A common objection to the use of mouth rinses among dental professionals is the understandable concern that it reduces fluoride retention following brushing with a fluoridated dentifrice. This issue has been thoroughly investigated in a number of trials, and it has been shown that rinsing with a fluoridated mouth rinse does not lead to loss of fluoride versus brushing alone.4 See the data here

Enamel demineralisation has a number of causes, therefore its treatment will aim to target a number of factors. A ‘high fluoride’ mouth rinse can increase fluoride levels above those possible with brushing alone5, which may be of benefit in these patients. Likewise dentine hypersensitivity has a number of possible causes;6 mouth rinses that contain compounds that are proven to reduce sensitivity could be a valuable adjunct to treatment.6–8 Read more about dentine hypersensitivity here.

Mouth rinses may also have a role in tackling halitosis and can reduce calculus formation to keep teeth whiter.
