How to whiten teeth

Red lips and white teeth, I believe that as women, we all envy women with such appearance. People all hope to have white teeth, but many people are troubled by yellowing and blackening of teeth. What causes yellowing of teeth? What should I do if my teeth turn yellow? Below, the editor will analyze the reasons for yellowing teeth. Preventing this phenomenon from the cause will achieve twice the result with half the effort.

1. Causes of yellow teeth

1. Developmental factors

During the development of teeth, due to malnutrition, infectious diseases, high fever, and serious illness, the enamel of the teeth will be underdeveloped and calcification will be affected, and the teeth will become yellow and brittle. In this case, the enamel of the teeth will lose its luster and become opaque, and may be yellowish-brown.

In severe cases, the tooth surface may become rough and spotted, with incomplete shape and often bilateral symmetry. Dental nutritional disorders caused by developmental factors lead to poor calcification, which reflects the impact of past health conditions on the teeth. It is meaningless to supplement calcium and vitamin D after birth.

2. Drug factors

This is the "tetracycline teeth" that most of us know. Tetracycline drugs can cause yellow teeth. Tetracycline drugs were widely used in the 1960s and 1970s. Excessive use of this type of drug can accumulate in the tooth tissue, staining the inner layer of the tooth yellow. Taking too much tetracycline during the tooth calcification period (deciduous teeth during the mother's pregnancy, permanent teeth before the child is seven years old) can easily lead to tetracycline teeth. Children usually have to wait until the age of 7 to change their teeth before yellow teeth appear.

3. Hygiene factors

If you do not pay attention to oral hygiene and do not develop good brushing habits, a layer of food residues, soft plaque, tartar, smoke stains, red wine, rice wine, tea stains, coffee, and Chinese medicine will accumulate on the surface of your teeth. The yellowing of teeth in these cases is not due to the teeth themselves turning yellow, but is caused by not paying attention to oral hygiene. It only affects the surface color of the teeth and is relatively easy to remove.

2. Treatment of yellow teeth

Depending on the depth and cause of yellowing of teeth, different methods such as teeth cleaning, whitening toothpaste, teeth bleaching, whitening teeth stickers and porcelain restoration should be used for whitening. No matter which method of teeth whitening is used, it must be ensured that caries and periodontal disease have been treated and the teeth are healthy. Otherwise, dental diseases will be aggravated.

1. Whitening teeth stickers

The latest and most popular teeth whitening method is convenient, fast, simple and cheap. It has been popularized in foreign countries for a long time. The clinical effect is still quite obvious and it has a tendency to gradually replace bleaching. However, whitening teeth strips are not suitable for teeth with discolored dentin due to tetracycline, fluorosis, etc.

2. Cold light whitening technology

The bleaching agent covering the tooth surface is irradiated with a special cold light source, allowing it to penetrate into the hard tissue of the tooth in a short period of time to achieve the purpose of changing the color of the teeth. Its advantage is that it does not damage the hard tissue of the tooth and the operation treatment time is about 30 to 45 minutes. However, the disadvantage is that due to the bleaching effect of the drug, the bleaching effect varies from person to person.

3. Teeth cleaning

Many people think that teeth cleaning is a cosmetic whitening of teeth. In fact, the main function of teeth cleaning is not whitening, but a routine dental care method. It is a routine health care method that mainly prevents caries, gums, and periodontal diseases, targeting tartar and plaque on the surface of teeth. Cleaning your teeth through regular teeth cleaning once every six months is a good habit to maintain dental health. Although the purpose of teeth cleaning is not to whiten teeth, teeth will naturally look whiter after cleaning.

The editor reminds everyone that in addition to daily dental care and cleaning, it is necessary to have regular dental examinations. Many people pursue white and beautiful teeth one-sidedly, blindly pursue teeth whitening, and use many folk remedies for whitening, but they don’t realize that this is hurting their teeth. Therefore, the editor recommends that it is better to whiten your teeth under the guidance of a professional dentist.
