The first condition for beautiful and healthy teeth is that they are strong enough. The main components of teeth are calcium and phosphorus, and calcium and phosphorus need to be obtained from food. The human body has sufficient intake of calcium and phosphorus, coupled with the attention to oral hygiene, the teeth are well protected, and the teeth will be strong and white. In the daily diet, more intake of foods rich in calcium and phosphorus can play a good role in protecting and strengthening teeth.

Foods rich in calcium include small shrimp, clams, eggs, milk, stewed bone broth, crispy fish, and green leafy vegetables and beans.

Phosphorus is widely distributed in food. Vegetables such as meat, fish, eggs, milk, beans, cereals and onions are rich in phosphorus. In addition, attention should be paid to the intake of vitamin d, because vitamin d has the effect of promoting calcium and phosphorus absorption and regulating bone calcium. Foods rich in vitamin D include animal liver and cod liver oil.

Raw onions kill a variety of bacteria, including Streptococcus mutans that cause our teeth to decay. The lentinan contained in shiitake mushrooms can inhibit the bacteria in the mouth from making dental plaque.
