Have you heard of the ‘bright smile’ diet?

It can help you make friends, win that job, pull that hot guy or even get you a free coffee at Pret. A beautiful, beaming smile makes you look happier and appear more attractive – it’s your golden ticket to success.

According to the British Dental Association, teeth whitening is the most popular cosmetic dentistry procedure in the UK, but before you spend hundreds on whitening strips, toothpaste and treatments, how about starting with your diet. Bacteria absorbed from food can not only leave stains and yellowing, it can also cause tooth decay, so we’ve asked our experts to tell us what to eat to perfect that million-dollar smile.

Dr Krystyna Wilczynski, a cosmetic dentist at the Hyde Dental Practice and facial anaesthetist:

Say ‘YES’ to:


Studies show that eating cheese can raise the pH level in your mouth and reduce the chance of tooth decay. It also contains calcium, which is fantastic for enamel strength.

Pumpkin seeds

Packed with nutrients and vitamins, they contain zinc, iron and magnesium which strengthen tooth enamel and prevents decay.

Green Tea

It has been known to reduce bacteria and the toxic products they produce in the mouth. Tea is also rich in fluoride – the most well know tooth strengthener.


Raw broccoli (instead of steamed or roasted) can act as a natural toothbrush to remove external staining on teeth. It also contains high levels of iron, which can help reduce acid erosion leading to the discolouration of teeth.


They are not only low in calories and perfect for snacking but also contain malic – a natural tooth whitener!

Dr Richard Marques, celebrity dentist:

Say ‘NO’ to:


The nation’s favourite snack is full of starch that turns into sugar in the mouth. This then gets trapped between the teeth and creates bacteria which causes plaque, so always be sure to floss after indulging.


It can get stuck in the tiny spaces between your teeth causing a build-up of plaque.

White bread

It contains simple carbohydrates including sugar which dissolves in the mouth, which then creates erosive acids when you chew. Rinse with a mouthwash after consuming and use dental floss to prevent build-ups.


They are surprisingly acidic, which can cause tooth erosion and damage to the enamel. If eating them raw, always consume with other foods such as in a salad, as this will not directly expose your teeth.

Balsamic vinegar

It’s deeply pigmented and full of acid, so will stain the teeth and cause erosion. Drink a glass of water after you eat anything containing vinegar to help clear any lingering acids.
