Want Shinning Teeth? Eat Apple, Chew Gum

Neutralise acid: Chewing gum is also very beneficial when it comes to maintaining a white smile. Chewing gum helps to clean teeth mechanically by removing debris, and it stimulates production of saliva, which increases your saliva's ability to neutralise acid and remineralise your enamel. This ultimately strengthens teeth.

Quit smoking: Lifestyle choices can also influence a natural white smile with smoking being one of the biggest causes of teeth decay and discolouration. The nicotine and tar in the cigarette result in teeth darkening, losing their natural white.

The little extras: Flossing removes some of the staining between teeth, making your smile instantly look whiter. Try to floss several times a week as this will not only improve the health of your gums, you will also notice your smile looking brighter.

See the light: Dark coloured foods are also notorious for causing discolouration in the naturally white teeth enamel. The best thing to do is try to avoid these foods and drinks such as coffee, balsamic vinegar and red wine, but if you do want to treat yourself, drink a glass of water after as this will help minimise staining.
