40 Best Superfoods To Maintain Oral Health

| Reviewed By Sneha Krishnan

Superfoods are great for your health, including your oral health. Foods which are rich in starch and sugar serve as the most loving eatables for bacteria that reside in our gums. They convert the sugars into harmful acids that cause our enamel to decay leading to several gum diseases such as gingivitis or periodontitis.

Diets play a vital role in promoting our oral health and ensuring the bright and beautiful smile on our face. Also, a healthy diet makes our immune system stronger, which in turn helps in keeping away all the health problems, including gums and teeth health. Take a look at these amazing superfoods for oral health.

Periodontitis: Symptoms, Causes, Risk factors, Treatment And Prevention

1. Cheese

Cheese reduces enamel demineralisation and helps maintain good oral health. Chewing cheese activates saliva production and it's alkaline property neutralises the acid formed on teeth by bacteria. The saliva produced also helps to dilute the sugar in the mouth. [1]

2. Milk

In a study, it has been observed that milk proteins such as casein and lactoferrin attach themselves to the teeth and prevent tooth decay bacteria (Streptococci mutant) from attacking them. Also, phosphorylated peptides in milk help to maintain tooth minerals. [2]

3. Yoghurt

Yoghurt is a probiotic that helps in stabilising the oral microbiota and maintaining the good health of gums and teeth. The two bacteria in yoghurt, lactobacillus and bifidobacterium may help control the growth of cariogenic bacteria, thus preventing tooth decay. They also help in warding off bad breath. [3] However, the effect of probiotic bacteria for oral health need more research.

4. Oranges

Orange contains compounds such as tannins, terpenoids and flavonoids which are effective against the oral bacteria. A study says that orange peel extract has an antibacterial property that shows potent behaviour against oral pathogens. [4]

5. Apple

Leftover foods in the mouth are decomposed by the oral bacteria causing the production of acids that decay the teeth. Crunching apple stimulates the production of alkaline saliva that reduces acid in the mouth.This is why, apple is considered one among the best foods for oral health.

6. Pears

In a study carried out on 30000 participants, it was found that individuals who had a less dietary intake of fruits like pears lost more than five teeth during a four-year follow up period compared to the ones who had a maximum intake. Fibre, vitamin C and E in pears help in maintaining good dental health. [6]

7. Watermelon

Watermelon is a great source of lycopene (antioxidant) along with vitamin B (B1, B6), potassium and magnesium. According to a study, lycopene is known to prevent multiple diseases along with oral cancer and other oral diseases. [7]

8. Cranberries

Polyphenols in cranberries play a very promising role against gum diseases like periodontitis. It inhibits the production of acid by the streptococcus mutans bacteria found in the mouth, thus preventing and treating oral diseases. [8]

A powerful proteolytic enzyme named bromelain in pineapple exhibits antiplaque and anti-gingivitis properties. Plaque and gingivitis are the most common oral diseases which can easily be treated at home with the consumption of pineapple. [9]

10. Papaya

Papain in papaya possesses the same anti-plaque and anti-gingivitis properties like bromelain. Stain in a tooth is built up in the thin protein layer that protects the enamel. Papain helps in removing the stains by dissolving the pellicle layer. [10]

Onion shows antibacterial activity against streptococcus mutans, the main gingivitis and periodontitis causing bacteria in adults. A study says that onion extract affects cultured bacterial cells of the mouth. The extract was also known to show effect for 48 hours. [13]

16. Garlic

Allicin in freshly cut or chopped garlic is known for its therapeutic property. A study proves the antimicrobial activity of allicin on dental pathogens which are linked to periodontitis as well as all types of bacteria. Even a minimum concentration (300 mcg/mL) of allicin inhibits the growth of oral bacteria, alleviating various dental diseases. [14]

17. Cucumber

Cucumber is among those crunchy vegetables that help in maintaining good oral health. The water content in this veggie helps wash away the acid in the mouth along with harmful dental bacteria.

20. Spinach

Leafy vegetables such as spinach contain a high amount of dietary nitrate. When they are consumed, the oral microbiota converts the nitratein to nitrite. The salivary nitrite possesses anti-inflammatory properties on the oral cavity. It was found that people who have periodontitis have less amount of NO2 in their saliva. [16]

21. Mushroom

Shiitake mushroom has anticaries and anti-gingivitis properties. They prevent demineralisation of teeth caused by oral bacteria. Also, they lower the number of oral pathogens without affecting the bacteria which is good for oral hygiene. [17]

This legume is rich in phosphorus and calcium. These compounds promote oral health and keep away bacteria which cause oral diseases. Also, chewing black-eyed peas stimulates saliva that helps neutralise the acid in the mouth.

25. Broccoli

Particularly in elders oral health is very important. Poor dental hygiene leads to tooth loss and periodontitis which is linked to the increased risk of oral cancer, heart diseases, dementia and cognitive dysfunction. Introduction of broccoli in diets helps in adding nutrients to the body which helps fight multiple diseases including oral problems. [20]

32. Raisins

According to the US Department of Food and Nutrition, raisins help protect against cavities due to the presence of five phytochemicals and antioxidants. These compounds prevent streptococcus mutans bacteria to stick to the teeth's surface, thus preventing bacterial growth in the mouth.

33. Sesame Seeds

Sesame oil derived from sesame seeds help reduce plaque-induced gingivitis. Sesame seeds are rich in chlorosesamone that possesses antifungal activity. Also, the presence of polyunsaturated fatty acid in the seed reduces oxidative damage to the oral cavity. [24]

34. Pumpkin Seeds

Pumpkin seeds are a powerhouse of nutrients such as vitamin A, vitamin C, zinc, iron and magnesium. Vitamin A and C help with gum problems and act as anti-inflammatory for oral diseases. On the other hand, magnesium strengthens the enamel and zinc treats bleeding gums.

Water is the easiest and effective choice for maintaining oral health. Consuming water helps wash away the leftover food particles in the mouth, preventing bacteria to convert them into acids and causing oral diseases. It also helps in the saliva production that neutralises all acids in the mouth.

40. Soy

In a study carried out on 3956 Japanese females, it was found that intake of soy or soy products is linked to decreased risk of periodontal health. Isoflavones in soy modulate the production of cytokine that helps in boosting the immune system to fight against foreign material. The Good immune system maintains good oral health.
