Chewing sugarfree gum could help oral hygiene maintenance

shutterstock_296458922Chewing sugarfree gum after eating or drinking is a valuable tool that can help support oral hygiene when patients don’t have immediate access to more traditional oral care techniques.

The European Commission (EC) has approved five oral health claims for sugarfree chewing gum, one of the few food categories to gain such recognition (EFSA, 2010).

EC claims include three claims for general function (neutralisation of plaque acids, maintenance of tooth mineralisation, reduction of oral dryness) and two claims for disease risk reduction related to dental caries (neutralisation of plaque acids, reduction of tooth demineralisation).

Chewing sugarfree gum promotes the production of saliva, the natural protection mechanism of the mouth.

It stimulates the salivary glands to produce a strong flow of stimulated saliva, a 10- to 12-fold increase over resting saliva rates during peak stimulation.

Stimulated saliva enhances the mouth’s natural ability to fight dental disease by neutralising plaque acids, and supporting tooth remineralisation (Dawes and Macpherson, 1992; Hein, Soparkar and Quigley, 1961; Leach, Lee and Edgar, 1989).

Furthermore, new research published in the British Dental Journal showed that significant NHS cost savings could be made if more people chewed sugarfree gum after eating or drinking (Claxton, Taylor and Kay, 2016), thanks to the role it plays in helping to prevent tooth decay.
