Good oral health is essential for overall health and well-being. It is widely known that brushing and flossing your teeth regularly can help maintain good oral hygiene, but did you know that eating certain foods can also improve your oral health? 

In this article, we will explore the impact of food on oral health and provide some examples of foods that can promote healthy teeth and gums.

Why Is Food Important For Oral Health?

First, let’s understand why food is important for oral health. When you eat, the bacteria in your mouth break down the carbohydrates and sugars from the food and produce acid. This acid can damage your tooth enamel, which leads to cavities and tooth decay. However, some foods can help neutralise this acid and promote the production of saliva, which helps wash away food particles and bacteria.

Foods And Drinks That Can Improve Your Oral Health

Dairy Products

One of the best foods for oral health is dairy products. Dairy products like cheese, milk, and yoghurt are high in calcium, which is essential for strong teeth and bones.

Additionally, cheese contains casein, a type of protein that helps neutralise acid in the mouth. A study found that people who ate cheese had lower levels of acid in their mouths compared to those who ate sugar-free yoghurts or drank milk.

Australian dairy products are among the best in the world, with many farmers using sustainable and ethical farming practices. In fact, the Australian dairy industry has a strong commitment to animal welfare and environmental sustainability. 

Some popular Australian dairy products that can promote oral health include cheddar cheese, Greek yogurt, and milk.

Fruits and Vegetables

Another food that can improve oral health is crunchy fruits and vegetables. Apples, carrots, celery, and other crunchy fruits and vegetables can help clean your teeth by acting as a natural toothbrush. 

The fibre in these foods helps stimulate the production of saliva, which can neutralise acid in the mouth and wash away food particles and bacteria.

Australia has a wealth of fresh fruits and vegetables, thanks to its diverse climate and geography. Some of the best fruits and vegetables for oral health include apples, carrots, and leafy greens like spinach and kale. 

Australian-grown apples are particularly high in fibre and vitamin C, which can help strengthen your teeth and gums.

Hard, fibrous fruits such as apples can act as natural toothbrushes, helping to scrub your teeth clean. Additionally, consuming apples can boost saliva production, which can help neutralise harmful citric and malic acids present in your mouth. Unlike sugary apple juice that can promote tooth decay, fresh apples are less likely to cause dental issues. 

The fibrous texture of apples also stimulates your gums, further decreasing cavity-causing bacteria and increasing flow of saliva. 

Similarly, raw pears are effective at neutralising acidic substances in your mouth that can contribute to tooth decay, making them a valuable addition to your dental care routine.

Green Tea & Coffee

In addition to dairy products and crunchy fruits and vegetables, there are other foods that can promote oral health. 

For example, green tea and coffee contain polyphenols, which can help reduce the growth of bacteria that cause cavities and gum disease. 

Australian-grown green tea is becoming increasingly popular, with many tea companies sourcing their tea from local growers. Some popular Australian green teas include Australian Sencha, Mount Romance, and Tielka. These teas are not only good for oral health but also for overall health, thanks to their high levels of antioxidants.


When it comes to beverages, water stands apart from the rest as the ultimate drink for optimal health. Constituting about 60% of our body, staying hydrated with water is crucial for facilitating nutrient distribution, eliminating waste, enhancing skin radiance, and maintaining muscular mobility. 

What’s more, consuming fluoridated water can significantly boost your dental well-being, as fluoride is recognised as a natural enemy of cavities. This simple and highly beneficial practice of drinking water, especially fluoridated water, can help wash away food remnants, promote high saliva levels, and keep your teeth healthy.


Nuts are a veritable treasure trove of dental health benefits. Rich in essential nutrients like calcium and phosphorus, they offer a range of advantages for your teeth. Of particular note are almonds, Brazil nuts, and cashews, which have been shown to combat the bacteria that contribute to tooth decay. 

Peanuts, in particular, are an excellent source of calcium and vitamin D, while almonds provide ample amounts of calcium that promote healthy teeth and gums. 

Cashews are renowned for their ability to stimulate saliva production, which can help protect your teeth against harmful bacteria. 

And let’s not forget about walnuts, which contain an array of vital nutrients like fibre, folic acid, iron, thiamine, magnesium, niacin, vitamin E, vitamin B6, potassium, and zinc, all of which can contribute to better overall dental health.

Foods Bad For Oral Health

There are some foods that you should avoid or consume in moderation if you want to maintain good oral health. Sugary and acidic foods like soft drinks, candy, and citrus fruits can erode tooth enamel and lead to cavities and tooth decay. 

Additionally, starchy foods like bread and chips can stick to your teeth and provide a breeding ground for bacteria.

In conclusion, eating certain foods can improve your oral health by promoting the production of saliva, neutralising acid in the mouth, and providing essential vitamins and minerals. Dairy products, crunchy fruits and vegetables, green tea, and other foods can all promote good oral hygiene.

However, it is also important to avoid sugary and acidic foods and consume starchy foods in moderation. By combining a healthy diet with regular brushing and flossing, you can maintain good oral health and prevent dental problems.
