If you have had laser teeth whitening, there are several things to keep in mind to keep your teeth white for as long as possible before you need the treatment again.
Stay away from colour-causing foods, especially in the days immediately after the session, when the enamel is most receptive to staining.
That means coffee, tea, red wine, cola, tomato sauce, curry, beetroot and dark berries.
Rinse with water after anything strongly coloured, and use a straw for cold drinks that are likely to stain.
Stop smoking, or at least reduce it — tobacco is the single fastest way to undo a whitening result.
Keep up regular brushing and flossing, and book a professional cleaning when your dentist recommends it.
Results typically last about a year, so plan an annual visit to maintain the shade.
