7 Foods That Help Whiten Teeth and Improve Oral Health

Did you know that some of the foods you eat can help make your teeth whiter?

Aside from taking care of your dental heath, regular dental cleanings, and having your teeth whitened by a professional, your diet can also impact your teeth,

Here are seven foods that you should eat and drink to keep your mouth happy and healthy.


Strawberry juice has a lot of malic acid, which is also found in some types of toothpaste. Malic acid is a natural astringent that helps get rid of stains on the surface of teeth.

It’s important to remember that strawberries also contain citric acid, which weakens the enamel. So, you should wait at least 30 minutes before brushing your teeth after eating strawberries or other acidic foods.


Speaking of malic acid, watermelon has more malic acid than strawberries! The malic acid could help whiten your teeth and make you salivate more.

Apples, Celery and Carrots

Apples, celery, and carrots, which have a crunchy texture, can help remove plaque and bacteria in your teeth, make you salivate more, and give you good sources of vitamins and minerals that make your teeth stronger.

Leafy Greens

Folic acid, also called B9 vitamin, is found in leafy greens like spinach, romaine lettuce, and kale. Folic acid is needed for cell growth and repair, and it can help reduce gum inflammation and help teeth fight against plaque and bacteria.


Do you know what causes your teeth to become yellow? When you eat acidic and sugary foods, your enamel (outer part of your teeth) wears away. This causes the dentin underneath to show through. Dentin is naturally yellow in colour, which makes your teeth appear yellower too,

Now, how does cheese help? Cheese has calcium in it, which strengthens bone and tooth enamel. Cheese also has casein, which is a type of protein that helps repair tooth enamel and is found in milk. Also, chewing cheese makes you salivate more, which helps move bacteria out of your mouth and keep your mouth clean.


Pellicle is a layer of salivary proteins that covers your teeth. Your teeth are protected by the pellicle layer, but it also takes in colours from the food you eat, and can stain your teeth.

The pellicle layer also gives bacteria something to stick to. When bacteria build up, they can cause plaque and discolouration of the teeth.

But pineapple has a natural way of breaking down pellicle. It has an enzyme called bromelian that breaks down proteins. The proteins in your pellicle layer can be broken down by proteolytic enzymes.

Sugar-free Gum

Chewing sugar-free gum between meals and snacks increases saliva production and helps neutralise and wash away acids that form in your mouth when food breaks down. This helps protect your teeth, keep them clean, and improve your oral health.
