Chapter 1: Eat More Rough Fiber Foods Like Celery

Vegetables like chives and celery, which are rich in rough fiber, are very effective for whitening teeth. The reason is very understandable: when chewing rough fiber foods, the rough fiber can rub the teeth, thus removing residual food and bacteria on the surface of the teeth, reducing tooth decay.

Chapter 2: Eat More Foods Rich in Vitamins

Some foods rich in vitamins, such as tomatoes and spinach, are very effective for whitening teeth. Vitamin C is an important nutrient for maintaining gum health. A deficiency of vitamin C in the human body can lead to problems with the gums, such as loose teeth and bleeding gums.

Chapter 3: Eat More Foods Rich in Calcium

Calcium is a necessary substance for dental health, so consuming more calcium in daily life is beneficial to the health and whitening of teeth. Dairy products and soy products are foods rich in calcium, such as milk and cheese. Cheese is not only a good source of calcium but also the calcium and phosphates in cheese can balance the acid-base value in the mouth, reduce the possibility of bacterial activity, thereby reducing tooth decay and can also increase calcium and strengthen teeth.

Chapter 4: Drinking Green Tea Appropriately

Green tea is rich in fluoride, which is essential for teeth and is necessary for whitening and strengthening teeth. Many toothpastes contain this substance. Fluoride can combine with hydroxyapatite in teeth to achieve the effect of acid resistance and caries prevention. Green tea, in addition to being rich in fluoride, can also refresh the breath.

Chapter 5: Apple

Although the crunching sound of chewing apples may be讨厌, this fruit is beneficial to dental health. The crispness of apples can strengthen the gums, and their high water content can increase saliva production, dispersing and neutralizing the bacterial colonies that cause bad breath and dental plaque.

Chapter 6: Baking Soda

You can temporarily avoid using toothpaste and try using this common chemical substance in daily life. Baking soda is an alkaline substance that has the effect of whitening teeth. This mild abrasive can scrub off spots and stains on the surface of the teeth.

Chapter 7: Celery and Carrot

The high water content of these two foods can stimulate saliva production, which helps to whiten teeth. They can rinse away food residue left in the mouth and increase the chewing power of the gums.

Chapter 8: Cauliflower

Unlike beets and cranberries, this crisp vegetable does not leave residues on the surface of the teeth, so it does not form unsightly stains. This cruciferous vegetable can clean the surface of the teeth, which is a simple and natural way to care for oral hygiene.

Chapter 9: Cheese

Cheese with a slightly firm texture is rich in calcium and can enhance the strength of teeth and gums. Moreover, most cheeses are nearly colorless, so they will not stain the teeth.

Chapter 10: Orange

This bright-colored fruit contains citric acid that can whiten teeth, but excessive consumption can wear away the enamel on the surface of the teeth; therefore, it can only be eaten in moderation.
