1, the correct method of tooth whitening
Medical tooth beauty is not recommended.
The common aesthetic aspects of teeth mainly include the shape and color of teeth. In view of the common problems of teeth, we can treat them with drugs such as porcelain teeth, ultrasonic cleaning and cold light whitening. However, the cosmetic effect achieved by medical methods is harmful to the structure of teeth themselves, so purely from a physiological point of view, tooth cosmetic is not recommended.
Second, eating more onions and mushrooms is good for strengthening teeth.
The first condition for beautiful and healthy teeth is that they are strong enough. The main components of teeth are calcium and phosphorus, which need to be obtained from food. Adequate intake of calcium and phosphorus by human body, combined with paying attention to oral hygiene and protecting teeth, will make teeth firm and white. In the daily diet, eating more foods with high calcium content and phosphorus content can protect and strengthen teeth.
Foods with high calcium content include shrimp skin, clams, eggs, milk, bone soup, crisp fish, green leafy vegetables and beans. Phosphorus is widely distributed in food, and it is rich in meat, fish, eggs, milk, beans, cereals, onions and other vegetables. In addition, we should pay attention to the intake of vitamin D, because vitamin D can promote the absorption of calcium and phosphorus and regulate bone calcium. Foods rich in vitamin D include animal liver and cod liver oil.
In addition, raw onions can kill many kinds of bacteria, including Streptococcus mutans, which causes our tooth decay. Lentinus edodes contains lentinan, which can inhibit bacteria in the oral cavity from producing dental plaque.
Three tooth cleaning tools are selected to protect teeth more efficiently.
Using proper daily dental care products can make teeth stronger and whiter in daily repeated care. Therefore, we should also pay close attention to the choice of toothpaste and toothbrush and choose the product that suits us best.
At present, toothpaste used in China is divided into three categories: ordinary toothpaste, fluoride toothpaste and medicinal toothpaste. Among them, the use of fluoride toothpaste can play a very good role in tooth fixation and whitening. Because fluoride can combine with calcium in teeth to form insoluble calcium fluoride, it can effectively prevent dental caries.
The choice of toothbrush should be based on the size of toothbrush head, the hardness of bristles, the angle between brush head and handle, the top of bristles and so on. One of the most important indicators is the hardness of toothbrush bristles. Generally speaking, bristles are divided into soft hair, neutral hair and hard hair, and it is more appropriate to use a toothbrush with neutral hardness. You can press the bristles with your fingers when you buy a toothbrush. If your fingers are numb, it means they are too hard and should not be used. Brushed toothbrushes do great harm to gums, which can lead to bleeding in severe cases. At present, toothbrushes sold in the market are basically packaged in plastic shells, so it is inconvenient to feel the hardness of bristles by hand. You can get information about hardness by observing the bristles: soft-bristled toothbrushes with uneven bristles at the top and hard-bristled toothbrushes with regular bristles.
Mouthwash should not be used too much instead of toothpaste.
Mouthwash is really convenient and quick. When you are on the road or in places that are not suitable for brushing your teeth, you can clean your teeth and mouth with mouthwash several times. However, whether it is a mouthwash for beauty or treatment, it should not be used every day like toothpaste, which may easily cause oral flora imbalance or other side effects.
In order to save time, some people simply give up brushing their teeth and rinse their mouths with mouthwash, which is not correct. Although gargling can remove food residues and some soft dirt from the mouth, it is far from thorough brushing. One of the main purposes of brushing teeth is to remove dental plaque attached to the surface of teeth. In this process, the most important thing is the physical friction of toothbrush, which mouthwash can't do, so it can't remove dental plaque.
Four simple DIY whitening techniques
In order to make teeth cleaner and whiter, the tooth cleaning service in the dentist's office can be said to be the fastest service, but frequent tooth cleaning can also cause harm to teeth. So how to whiten teeth in daily life can it be more effective and lasting?
Whitening teeth with lemon juice is very effective.
After brushing your teeth every night, rub your teeth with gauze dipped in lemon juice, and your teeth will become white and bright.
Lemon has a strong cleaning power and whitening effect, and contains vitamin C, which can strengthen the roots of teeth.
You can try tooth powder.
Toothpowder is very effective. Brush once every morning and before going to bed, and it will take about five to ten days to have an effect. Very effective. However, if your own teeth are yellow, you may have to go to various dental clinics for help.
Editor's Note: A sweet and clean smile can increase your popularity in interpersonal communication, while a mouthful of white teeth can add a lot of color to your smile, but you still need to be cautious when choosing whitening teeth, otherwise you will be in a dilemma.
2. Choose the right toothpaste method
1. Should I use one toothpaste for a long time or change it?
Try to use toothpastes with different effects and brands, so as to give full play to the various effects of different toothpastes, thus maintaining oral health.
2. Do I have to use fluoride toothpaste?
American dental care experts agree that fluoride toothpaste is the best choice. Experiments show that brushing your teeth with fluoride toothpaste twice a day reduces the risk of dental caries by 40%. Wang Weijian, director of the Department of Prevention at Peking University Stomatological Hospital, believes that fluoride toothpaste is not an inevitable choice for people with healthy teeth. Teenagers and the elderly can use it more, but preschool children should use it with caution and need the help of their parents to avoid swallowing toothpaste by mistake, which may lead to excessive fluoride intake in the long run.
3. What are the ingredients of toothpaste?
Toothpaste consists of a variety of inorganic and organic substances, including abrasives, washing foaming agents, adhesives, humectants, sweeteners, fragrances and so on. Among them, the friction agent is the main component of toothpaste. In recent years, some Chinese herbal medicines have been added to toothpaste to make toothpaste containing various drugs. But don't worry, all the ingredients are safe.
4. Does toothpaste have a shelf life?
When many people buy toothpaste, they find that some toothpastes indicate the shelf life, while others do not. Wang Weijian said that toothpaste has a shelf life, because the chemicals contained in it will react after being stored for a certain period of time, especially the toothpaste that has been opened, and it is best to use it up within one or two months. In addition, the longer a tube of toothpaste is used, the more chances it will be exposed to the air, and the greater the chance it will be exposed to bacteria.
5. Why is whitening toothpaste not effective?
Because the main component of toothpaste is friction agent, its basic function is to clean the mouth, and the functions of whitening, desensitization and hemostasis are auxiliary. The abrasive particles of whitening toothpaste have a special shape, which is more conducive to removing stubborn stains on teeth, so it can achieve the effect of whitening teeth to a certain extent. However, Wang Weijian pointed out that this toothpaste is only used to remove exogenous stains on teeth, such as "pollution" caused by drinking coffee, tea and smoking for a long time, and has no effect on deep endogenous stains caused by abnormal tooth development such as tetracycline teeth and dental fluorosis.
