Little knowledge of tooth protection, be brief.

1. Drink plenty of water. This natural gargling method can wash away the tooth stains left by drinking coffee, soda water and red wine.

2. Ensure a certain proportion of fruits and vegetables in the daily diet. When eating crisp fruits and vegetables such as apples, celery, cucumbers and carrots, the mouth will be cleaned by the way, because dental plaque and food residue between teeth and gums will be removed by these fruits and vegetables.

3. Eat cheese. After dinner, chewing a piece of cheese can neutralize the acid in the mouth, ensure the acid-base balance in the mouth and effectively protect the teeth.

4. Chew sugar-free gum. Chewing gum can promote saliva secretion, help reduce acidic substances on the surface of teeth and strengthen enamel. In addition, remember to brush your teeth after drinking a lot of acidic drinks, but orange juice and soda are exceptions. They have to wait at least 2 minutes before brushing their teeth, which can reduce the damage to enamel.

5. Wash with hydrogen peroxide. Rinsing your mouth with a small amount of hydrogen peroxide mixed with clear water can have obvious antibacterial and whitening effects, but remember not to swallow it. When you rinse your mouth, add a little baking soda. This abrasive substance can achieve the same cleaning effect as toothpaste.

6. Use a straw. Drinking coffee or red wine through a straw may seem strange, but doing so can reduce the chances of your teeth coming into contact with these drinks that can color your teeth.

7. Soften the toothbrush. Softening the hard bristles with hot water before brushing can relieve the pain of sensitive teeth.

8. It is indispensable to clean your tongue. This can reduce the influence of bad breathing habits, and at the same time, it can also improve oral hygiene, because there are a lot of bacteria on the wrinkled surface of the tongue. Most dental experts have pointed out that unsanitary oral cavity, such as not brushing teeth, not flossing or not cleaning properly, are the main causes of gingivitis and dental caries.

9. Avoid eating sugar and starch foods. Carbohydrate can support the bacteria that cause dental caries, not only dessert, but also a small biscuit. Try to eat healthy snacks, such as snacks made of celery and carrots dipped in bean paste or butter jam, vegetable biscuits with cheese or plain yogurt, fresh fruits and nuts.

1. Wash teeth and floss. Regular tooth cleaning or dental caries examination, although it is a small amount of money, can save you the high cost of future dental care.
