DIY teeth whitening trick – eating 'natural tooth whitener' will boost your smile


While some foods can stain the teeth, such as red wine and dark sauces, others can help to naturally whiten them. Dentist Hanna Kinsella advised adding them to your diet.

Strawberries in particular are good for naturally whitening the teeth, she said.

“Strawberries contain malic acid which is actually a natural tooth whitener,” Dr. Hanna told Express.co.uk.

Dr. Hanna Kinsella runs her own dental practice and founded her own dental range, Icy Bear Dental. 

Malic acid is found in a number of fruits. It’s closely related to citric acid and Vitamin C and is also sometimes taken as a supplement.

Dr. Hanna said: “Obviously don’t go too hard on the strawberries, and don’t rub them on the teeth or keep them against the enamel for too long, but a healthy amount of them can help with whitening.”

Which other foods contain malic acid?

Malic acid is found in many fruits.

These include apricots, blackberries, blueberries, grapes, cherries, peaches, plums, pears, and sour apples.

Other fruits can, therefore, also whiten your teeth.

Eating crunchy apples could have a tooth cleaning benefit. So perhaps the saying ought to go, an apple a day keeps the dentist away.

Dr. Hanna went on: “In the same vein, apples are a great way of cleaning the teeth (in some form!) as long as not eaten too aggressively.

“The rough edges of crispy food like apples can help to remove bacteria from the teeth.”

Drinking lots of water can also help keep the teeth healthy and white.

Foods not to eat for your teeth

  • Bread
  • Fizzy drinks
  • Sugary sweets
  • Wine

Dr. Hanna said: “Two of the most prevalent diseases, tooth decay, and periodontal or gum disease, may be preventable by making simple changes to your diet.”
