There are lots of different ways to whiten your teeth, with several professional and at-home treatments to choose from.

This article will explore some of the best ways to whiten teeth naturally and explain how to keep them white.

4 ways to whiten teeth naturally and keep teeth white

  1. Brushing and flossing

The first and easiest step when it comes to natural teeth whitening is maintaining good oral hygiene. Best-practice actions for white teeth include:

  • Regular brushing: Brushing your teeth at least twice a day is a basic habit but its importance when it comes to teeth whitening should not be downplayed. Brushing your teeth helps to remove lingering food and buff away stains from the surface of your teeth. You should aim to brush your teeth at least twice a day for two minutes, using a soft-bristled brush to brush in circular motions.
  • Flossing: While regular brushing can help get rid of food and drink that may be lingering, flossing will help to keep those hard-to-reach places clean and free from plaque build-up which can cause teeth to look dull¹.
  • Using mouthwash: Finishing your oral care routine with an effective mouthwash is a great way to help make sure that your mouth is free from lingering foods and any harmful bacteria.

Did you know that foods that are high in fibre can really help keep your teeth and gums clean by restoring minerals to those parts of your teeth that have lost them from bacterial acids.

When it comes to looking for safe teeth whitening, why not try incorporating apples or carrots into your diet, as they act as natural stain removers. They help to increase saliva production, which serves as the mouth's self-cleaning agent. Their crunchy texture also helps scrub teeth clean and as an added benefit, even helps kill bad breath.

Ripe strawberries are another great option, as they contain citric acid, which can whiten teeth naturally if applied directly to your teeth. Cheese, milk, plain yogurt, and other dairy products are one of the best ways to whiten teeth, as well as making them stronger. Apple, celery and carrots are also useful as they act as natural stain removers by increasing saliva production, which serves as the mouth's self-cleaning agent. Their crunchy texture also helps scrub teeth clean and as an added benefit, even helps kill bad breath.

  1. Prevent stains before they happen

A great way to keep and maintain a white smile is to prevent stains from happening in the first place. Ways to do this include:

  • Drinking water after eating and drinking: Drinking water after consuming food and drink helps to wash away any lingering items of food or staining drinks.
  • Drink staining beverages through a straw: Drinking through a straw helps to minimise the amount of contact the staining beverage has with your teeth.
  • Quit smoking: Quitting smoking or the use of other tobacco products helps to reduce and prevent nicotine stains on teeth as well as having the potential to improve your overall oral health³. For more information, read this article on smoking stains and removing them.
  • Reduce your consumption of staining foods and drinks: Reducing the number of staining items you consume can also help to maintain the natural whiteness of your teeth. If you can’t go without your morning coffee or tea, try adding some milk as this may help reduce its staining abilities⁴.
