The health of your teeth is influenced by the overall health of your body. If you have a poor diet, then your teeth will suffer as well. The various foods on this list are sure to make a positive impact on your body while working to strengthen and protect your teeth and gums.


The flesh of an avocado is full of prebiotic fibre to help with digestion while also feeding your oral and gut systems. Certain avocados, like the dark green Haas, contain more fibre than the lighter green Florida avocado, if you’re looking to gain the most fibre. Eating foods with increased fibre has been shown to reduce the chance of tooth loss by 30%.


Another good source of fibre to improve oral health, spinach is packed with vitamins and mineral. Vitamins A and C, as well as folic acid aid in strengthening teeth. Folic acid can help in treating gum problems as well. In addition, spinach is high in calcium, helping to build up and strengthen tooth enamel.

Green Tea

Rich in antioxidants, green tea can help reduce inflammation in the gums. The antioxidant (catechins) fights off the bacteria that causes gum disease, effectively boosting your body’s resistance. The same bacteria are responsible for helping cavities develop, so a cup of tea or two can really help to keep your teeth and gums healthy.


Chewing on celery helps to produce saliva, which is great for people with dry mouth. A lack of saliva in the mouth allows for the bacteria present to blossom into bad breath and possible infection. Saliva washes away that bacteria, preventing it from causing harm to your oral health.


Asparagus is a good dietary source of inulin, a prebiotic fibre that helps in digesting other probiotics. As with eating avocado, the fibre from asparagus will help to improve oral health by reducing the chances of tooth loss and decay.


Onions contain strong antibacterial sulphur compounds that fight against bacteria. It helps to ensure healthy gums while aiding in the prevention of cavities. Adding more onions to your diet will benefit your oral hygiene immensely.


Fermented milk is packed with probiotics that aid in improving and maintaining oral health. The lactobacillus bacteria found in kefir can help to prevent strep mutans, a bacteria that can cause tooth decay. If the milk isn’t to your liking, consuming any fermented foods can help to inhibit tooth decay. The probiotics in fermented products can also aid in improving your immune system, which in turn will help to control bleeding gums.

Shiitake Mushrooms

These mushrooms contain lentinan, an antibacterial compound, which helps to prevent bacteria from creating plaque. Plaque-causing bacteria breeds in hard to reach places, like between teeth and along the gum line. This bacteria can lead to gingivitis and gum disease, which is why consuming shiitake mushrooms is important in improving your overall oral health.
