A neat, white tooth can add points to your appearance and give people a healthy and beautiful feeling. But many people's teeth always have some dirty places, even if they brush their teeth, they can't be cleaned, so try cold light whitening teeth. How long can the effect of cold light whitening teeth last? What effect does cold light have on whitening teeth?

1, cold light whitening effect of teeth

Contemporary plastic experts tell you: how long can the effect of cold light whitening teeth last?

Everyone wants to have white and beautiful teeth. But with the growth of age, after years of material deposition, teeth will turn yellow and black. Although teeth can become white and beautiful through cold light whitening. But there will be pigment deposition in life, so cold light whitening is not once and for all. How long can the cold light whitening effect last?

Contemporary plastic dentistry experts say that in theory, the effect of cold light whitening can generally last for about two years. I have been doing cold light whitening since 2003. Through follow-up investigation, some people have maintained it for about two years, while others are still very good. It seems that how long the effect of cold light whitening teeth can last depends on individual eating habits and tooth structure.

The cold light whitening effect of mild and moderate tetracycline teeth and dental fluorosis teeth is better, and the color of heavily colored teeth can be improved. Light-colored teeth can be whitened once, moderate-colored teeth can be whitened once, and then do it again after one month. Experts say that teeth that have not received any whitening treatment before will have a better and more lasting whitening effect.

Finally, I would like to remind you that teeth are easily contaminated with colored substances within 24 hours after cold light whitening. Therefore, it is not advisable to drink colored drinks such as tea, coffee, cola, red wine, soy sauce and other dark foods after cold light whitening, and do not smoke. Everything returned to normal after 24 hours.

3. Food for whitening teeth

(1) carrot

Lack of vitamin A can lead to periodontal disease. This is because vitamin A can enhance the resistance of enamel and the vitality of epithelial cells in periodontal tissue. Carotene is the "treasure house" of vitamin A. Eating three carrots a week on average can keep the normal level of vitamin A in the body.

(2) Strawberries

Strawberry is a natural tooth whitening fruit, which can not only make teeth stronger, but also contain some ingredients that can bleach and clean teeth and remove stains on the surface of teeth.

(3) spinach

Fresh spinach contains 99% water, which can dilute the sugar in the mouth, make it difficult for bacteria to grow and prevent dental caries. In addition, spinach is a dark green vegetable, which contains a series of minerals such as magnesium, which helps to form an antifouling film on the tooth surface and plays an important role in keeping the enamel white.

(4) Apple

Apple is a fruit rich in fiber and needs more time to chew. In the process of chewing, you will secrete a lot of saliva, which is the best protector of teeth. It can clean and strengthen teeth, prevent tooth decay, and prevent bacteria from attaching to teeth, thus making it easier to keep teeth clean for a long time. Studies have found that saliva contains a lot of mineral elements, which can repair early tooth decay.

(5) Cauliflower

Cauliflower will not remain on the surface of teeth. It can be used as a "scrub" to whiten and clean the tooth surface, which is equivalent to simple care of oral hygiene. At the same time, cauliflower can stimulate the production of saliva and help prevent the formation of dental plaque.

(6) Dairy products

Everyone knows that insufficient calcium intake will damage the health of teeth, so we should supplement calcium from various natural foods every day. Dairy products such as yogurt and cheese are not only one of the good sources of calcium, but also have other protective effects on teeth. The rich trace elements such as calcium and phosphorus in dairy products help to balance the pH value of the oral cavity and avoid the oral cavity being in an acidic environment all the time, thus improving the health of enamel. Eating dairy products regularly can increase calcium on the surface of teeth, strengthen and rebuild enamel, and clean and strengthen teeth.

Eating more of these foods can make your teeth whiter and your body healthier. I hope everyone can develop good living habits.
