Oral Health and Genetic Risk Factors

What you eat can affect the health of your teeth

When it comes to proper dental care, most people immediately think of regularly brushing their teeth, flossing and using mouthwash. These are indeed important towards your oral health, but you need to take extra steps to ensure that your teeth are strong and free of infections.

Dietary choices play a key role in overall oral health, and specific foods have been shown to boost the strength of the teeth, gums and jaws. To obtain healthier teeth and a brighter smile, you can supplement regular brushing and flossing with eating the right foods. 

Dairy products

The enamel (the outer layer of the teeth) is primarily made of calcium and phosphorus. Consuming foods rich in either of these minerals will strengthen the teeth and the underlying jawbone. Dairy products are typically rich in calcium and can protect the teeth from erosion or becoming decayed.

Try to incorporate milk, yoghurt and cheese into your diet on a regular basis to ensure the teeth remain white and strong. Cheese is particularly beneficial because it contains high amounts of phosphorus, which is the other ingredient that is infused with calcium to strengthen the enamel.

Fruits and vegetables

Fruits and vegetables are always healthy for the body, and they're healthy for the teeth as well. Fruits that contain vitamin C (such as oranges and other citrus products) promote healthier gums by improving the health of connective tissues and periodontal ligaments. Vitamin C also prevents the accumulation of plaque, which can decay the teeth or cause them to turn yellow.

Don't forget your vegetables. Broccoli, potatoes and carrots strengthen the enamel due to their rich supply of vitamin A. Vitamin A can also boost immune function and prevent the occurrence of tooth and gum infections.


Cereals are also a good choice for your teeth, if you select the right ones. Sugary cereals are not the best option, as they tend to dissolve in the mouth and erode the teeth over time. Instead, opt for cereals such as rice, barley and oats. They contain magnesium, which is another mineral that is used to form tooth enamel and to strengthen the jaw.


Proteins in the diet also assist in the development of healthier teeth. Foods such as lean beef, eggs and turkey contain phosphorus that is a key ingredient in enamel formation. Proteins also reduce tooth decay by promoting healthier teeth, the growth of nerve cells and a stronger immune system.
