Dr Luisa Dillner's guide to ... flossing

• You may think it's simple, but there's a technique. Use waxed floss (easier to slide) and pull off around 40cm. Wrap one end of the floss round your middle or index finger on one hand and the other end round the thumb of your other hand. Using a gentle circular action slide the floss between the gaps in your teeth. Make sure you reach where the tooth meets the gum - gently. Rub the floss up and down each tooth.

• It's best to use a mirror, which will help you to see inside your mouth.

• Superfloss, which has thinner bits of floss, is best for getting under bridges. And don't use needles or earrings to floss, which some people do.
