How Your Diet Affects Your Oral Health: Best Foods for Healthy Teeth

Our diet is a make-or-break factor in our oral health. No matter how great your brushing and flossing routine is, if you only eat sugary and starchy foods, you’re still at a high risk of developing cavities and gum disease… not to mention a host of other avoidable health problems!

So, what are some of the best foods for healthy teeth? Here, Victorian Dental Group names the best foods for a cleaner mouth and better overall health:

Fibre-rich fruit and veg

Fibre is important to keep your teeth clean, which is why crunchy, fibrous fruit and veg are great for your oral health. They also produce saliva which is the body’s natural defence against cavities and gum disease. Apples, carrots and celery are all favourite fruits and vegies among dentists for their teeth-cleaning properties.

Cheese, milk and plain yoghurt

Low-sugar dairy products work on your oral health in two ways: 1) they help your mouth produce saliva and 2) they’re rich in calcium and phosphorus which are key minerals for strong, healthy teeth. Avoid sweetened versions of these dairy products, like flavoured milk and fruit-flavoured yoghurt – it’s much better to have plain yoghurt and add fresh fruit to it for sweetness. When drinking red wine, which is acidic and can eat away at enamel, ensure you pair it with your favourite cheese to reduce its effects and add calcium back to the teeth.

Nuts

Nuts are packed full of nutrients and minerals which are beneficial for your teeth. These include Brazil nuts, almonds and cashews which are loaded with phosphorus – a mineral which is essential for building healthy teeth. Peanuts are an excellent source of vitamin D and calcium, also essential for healthy teeth.

Lean meats and fatty fish

Lean meats and fatty fish also top our list. Lean red meats have high quantities of phosphorus and they also help to produce saliva, which washes away bacteria in your mouth. Fatty fish like salmon and soy products like tofu are also great for your teeth thanks to their high phosphorus levels.

Green and black tea

You might be surprised to hear tea make it on our list of best foods for healthy teeth, considering they’re associated with teeth staining. However, green and black tea contain polyphenols which kill or reduce plaque bacteria, making them the perfect alternative to soft drinks. Enjoy a morning cup of black tea, or a nice green tea in the arvo to give you energy while keeping your teeth healthy.

Sugar-free gum

Sugar-free chewing gum is great for your teeth as it helps to stimulate your salivary glands – and saliva is your mouth’s natural defence against bacteria.
