1. What should I do if my teeth are particularly yellow?
1. 1, baking soda: when brushing your teeth, add a little baking soda to the toothpaste. Brush your teeth as white as jade for three times, and the tooth rust will naturally fall off.
1.2, aged vinegar and white vinegar will do. Put it in your mouth 1 to 3 minutes, then spit it out and brush your teeth. The effect is very good. But even the teeth will feel very sour and numb, so they can't do it continuously and often. Just do it once every 2 months or so, otherwise it will be bad for your teeth.
1.3, lemon+apple vinegar: mix lemon juice and apple vinegar according to the ratio of 1: 1, and gently wipe the tooth surface with a cotton pad. Once every morning and evening, it will take effect after one week.
1.4, eat more fruits and vegetables with high vitamin C content: some data show that 40% of teeth turn yellow due to calcification, and adequate vitamin C can effectively prevent bone calcification and maintain the natural color of teeth. I suggest you eat more fruits and vegetables rich in vitamin C, such as broccoli, tomatoes, kiwis, strawberries, etc., which are the guarantee to make your teeth bright and white.
1.5, one xylitol a day: chewing xylitol can increase saliva secretion, neutralize acidity in the mouth and prevent teeth from discoloring due to corrosion. Xylitol in sugar-free chewing gum can also effectively inhibit bacteria that cause dental caries and avoid tooth growth! But generally speaking, chewing gum for 7 minutes a day is enough, and chewing more will make the masticatory muscles bigger.
2. Why do teeth turn yellow?
2. 1, health factors: during the development of teeth, due to malnutrition or illness, it will affect the calcification of teeth, and teeth will become yellow and brittle.
2.2. Water quality factor: In some areas, especially in some mountainous areas, because of the high fluorine content in water, teeth with excessive fluorine will turn yellow, instead of 1-2 teeth, which are full of rhubarb teeth. Fluorine can prevent dental caries, so these people are not prone to dental caries (tooth decay).
2.3. Drug factors: Now most people know that tetracycline drugs can cause yellow teeth, especially children (before 5 years old).
2.4. Hygienic habits: Some people do not pay attention to oral hygiene and have no habit of brushing their teeth. A layer of food residue, soft dirt, tartar, tobacco stains, tea stains, etc. Accumulate on the surface of teeth. These "yellow teeth" are not caused by the yellowing of the teeth themselves, but by careless oral hygiene.
3. Can yellow teeth be washed?
According to experts, tooth washing can make teeth slightly whiter, but it is different from tooth whitening. Tooth washing can remove dental calculus, coffee stains, tobacco stains, tea stains and so on. Accumulate on the surface of teeth for a long time and restore the original color of teeth. Therefore, the teeth will look whiter after washing, but they actually have no whitening effect on the teeth.
But tooth washing can clean teeth and prevent oral diseases. Generally speaking, once or twice a year is enough. Don't wash it too often.
4. Teeth will turn yellow if you drink tea for a long time
1, tooth yellowing is actually related to many factors. First of all, the teeth themselves will change with age, and yellowing is normal. Even if you accidentally touch colored substances or drugs, your teeth will change color.
In principle, drinking tea often will make teeth yellow. After all, there are tea polyphenols in tea. Although it is not easy to dye, if you drink tea for a long time, tea polyphenols will still adhere to your teeth. It is unreasonable to brush your teeth carelessly, and it is difficult to clean.
It's not because you drink too much tea that your teeth turn yellow. In fact, if you brush your teeth normally and clean them thoroughly every day, your teeth will not turn yellow.
5. Dental care in daily life
1, high fiber food, such as vegetables, coarse grains, fruits, etc. Very beneficial to teeth; Meat, eggs and milk with high calcium content can be eaten more; Avoid eating too many sweets.
2. Poor oral hygiene is the main cause of periodontal disease. Cleaning dental plaque and calculus in oral cavity in time, which is called "tooth washing", is one of the main means to prevent periodontal disease.
3. If we don't pay attention to oral hygiene or brush our teeth incorrectly in our daily life, there will be a lot of dental plaque accumulation on the tooth surface, especially the parts that can't be brushed by toothbrush, which will become dental calculus over time. If there are dental plaque and calculus on the tooth surface, which can not be eliminated in time, it will cause a series of diseases such as gingivitis and periodontitis.
6. Eating these teeth will turn yellow.
1, curry, turmeric, the main component of curry, ranks first, which has the greatest influence on tooth color.
2. chocolate.
3, carbonated drinks (carbonated drinks, such as cola), the ingredients of cola are syrup and carbon dioxide gas, drinking too much will make sugar precipitate on the surface of teeth.
4. Take too many diet pills.
5. coffee.
6. Sports drinks.
7. Fruit acid drinks.
8. Take some antibiotics when you grow up.
9. Strong tea (tea, tea beverage, black tea, etc.). ), there are a lot of polyphenol oxides in tea, and drinking tea for a long time will make teeth yellow.
10, too much food pigment.
