Tips on how to whiten teeth quickly a clean and tidy tooth with a bright smile will definitely be a famous brand for you, but many people's regional or eating habits will make their teeth turn yellow, which will not only strike people's confidence, but also make people feel embarrassed when they laugh. How can they turn white? What are the tips for turning white teeth? Let's have a look at them together!

The cause of yellow teeth

There are many reasons for tooth yellowing, including exogenous and endogenous staining. Exogenous coloring is due to the presence of a variety of bacteria on the surface of teeth, which secrete a lot of viscous substances. The tea dirt, smoke stains in daily diet and some minerals in drinking water adsorb on these viscous substances, gradually making teeth yellow or black. Endogenous coloration is formed in the process of tooth development. If tetracycline is deposited in the dentin, the teeth will turn yellow, brown or dark gray, which is called tetracycline teeth. If there is too much fluorine in drinking water, it may also lead to dental fluorosis. The tooth surface is white chalk and brown patches. If the nerve necrosis of teeth is combined with the decomposition products of bacteria, the teeth will also turn black.

What to do with yellow teeth

1. Often drink green tea

Green tea is not fermented tea, so it retains more natural substances of fresh leaves, contains more tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients. Green tea contains a lot of fluorine and apatite in teeth, which has the effect of anti acid and anti tooth decay. Catechins in green tea can reduce tooth decay in the mouth Streptococcus mutans, also can remove bad breath.

2. Keep toothbrush dry

Although I really want to keep my teeth white, no one wants to get nervous about it. But at least one thing you can do is not wet your toothbrush before you apply the powder. When the toothbrush contacts the molar powder when it is wet, the molar powder will be diluted, resulting in poor whitening effect. When brushing with dry toothbrush and molar powder, even if there is no change in the brushing method, it will also help your teeth become white.

3. Self made whitening toothpaste

First, use half spoon of baking soda and half spoon of salt, then add a drop of peppermint essential oil or olive oil, stir well to make a natural whitening toothpaste. Brush the teeth once a week, otherwise it is easy to damage the enamel.

4. Hold the toothbrush like a pencil

Does your toothbrush look like it washed a car? If so, you may brush too hard. On the contrary, those who are used to "happy scrubbing" think that brushing hard is not the best way to remove the plaque. The best way to do this is to position the toothbrush at a 45 degree angle to the gums and allow the toothbrush to move gently in a circular motion rather than back and forth. Hold the toothbrush like a pencil, so you won't brush too hard.

5. Brush your teeth after meal

Brushing your teeth immediately after a meal can quickly clean the remaining food and tartar in your teeth, but brushing your teeth immediately after a meal can increase the symptoms of tooth allergy. There is a layer of enamel on the surface of the teeth. After eating, especially after eating acid food, the enamel on the teeth will become soft. At this time, brushing will only make the enamel thin gradually. After a long time, the teeth are prone to ache and swelling.

6. Eat more dark green vegetables

Minerals contained in dark green vegetables such as spinach and broccoli help to form a protective film on the surface of teeth and prevent tooth discoloration. Dr. Thomas & middot; Connie, a beauty and dental expert in New York, also suggested that we should eat more apples, pears, celery and carrots. By chewing, we can promote saliva secretion, reduce oral bacteria and whiten teeth.

7. Change toothbrush regularly

Discard your old toothbrush or replace the head of your electric toothbrush at least every 2 to 3 months. Otherwise, you are sending bacteria to your mouth.

8. Eat more cheese

Cheese contains a lot of protein and fat, vitamin A, calcium and phosphorus, which can balance the acid-base value in the mouth, prevent the acid environment favorable for bacterial activity in the mouth, lead to tooth decay. Regular eating cheese can increase the calcium on the tooth surface, help to strengthen and rebuild the enamel, make the teeth stronger, and have whitening effect.

9. Mint is good for tooth whitening

Although Mint is a kind of plain flower, its taste is refreshing. It penetrates into the skin from every pore and every cell in the body. It's a very happy feeling. Mint leaves contain monometene compounds, which can circulate through the blood to the lungs. When breathing, it feels fresh and makes the teeth white.

10. Drink more water

Although tea, coffee and red wine are very attractive, they are the enemy of whitening teeth. How many people can resist these temptations? Actually, drinking water can help you get the best of both worlds. For example, if a cup of coffee is spilled on a wet towel, it will leave little trace if it is washed immediately. But I'm afraid it's not so easy to clean up if you pour coffee on a dry towel. Often drink water because the mouth is wet, even if drink some colored drinks will not be so easy to damage the white teeth.

11. Chewing celery

This method sounds absurd, but it's a very good one. I don't believe you can try it. Chew raw celery with a large mouth, let the rich crude fiber in celery wipe the tooth surface, and the pigment will not settle on the tooth easily.

12. Brush your teeth with orange powder

Dry the orange peel, grind it into powder, brush your teeth with toothpaste, and your teeth will soon be white. Grind the clean orange peel into a fine powder, add a little toothpaste every day when brushing, not only can make the teeth white, full of fragrance, because the orange peel has a strong antiseptic and sterilization effect, it can effectively firm teeth for a long time. The key point of this method is to stick to it every day. You will feel the whitening effect of using orange peel powder to make toothpaste.

13. Vinegar mouthwash

Pour vinegar into your mouth, let vinegar fully contact your mouth, stay for 2 minutes, then spit it out, and brush your teeth, you will feel your teeth turn white. This method can whiten teeth quickly, but it does harm to teeth, so it can't be used often.

14. Rinse your mouth for 30 seconds after eating

Remember to rinse your mouth for 30 seconds after eating, which is good for preventing tooth discoloration caused by phytochrome and removing food residue in your mouth. Therefore, sticking to mouthwash after eating can also help tooth whitening.

15. Floss your mouth regularly

Even if you brush your teeth five minutes a day, 30% - 40% of the teeth are not cleaned thoroughly, especially for people with irregular teeth arrangement. Floss can bring out the tartar in the 'hidden place' and reduce the incidence of caries. But don't use it frequently. Three times a week is the limit, or the gap between teeth will make you laugh.

16. Drinking straw

It's easy to damage enamel and cause tooth discoloration and decay when drinking carbonated drinks. It's recommended to use a straw when drinking such drinks.

It's said that the girls who love to laugh will not have bad luck, let alone our teeth are still so white. Of course, it's not bad to laugh. Let's start to add white teeth from today.
