Why do teeth turn yellow?
1. Externality: Pigment staining

Eating betel nuts, smoking, drinking alcohol, drinking coffee, even drinking all kinds of tea, soy sauce, black vinegar, etc., colored food will cause pigment to penetrate into the teeth;
Heavy metal ions in food and vegetables can also stain teeth.
2. Endogenous: drugs, diseases

Age, genetics, fluorosis, preparation (tetracycline), dental pulp lesions, etc .;
Teeth drawn from nerves will gradually turn into dark brown;
The accumulation of calculus will also cause the neck of the tooth and the adjacent surface of the tooth to appear black in some areas;

Common teeth whitening methods
Type 1: Sandblasting and whitening
Use a high-pressure sandblasting machine to combine baking soda powder with a strong water column to remove plaque, tea stains, coffee stains and soot. It is mainly suitable for those who have accumulated a lot of yellow or black dirt on their teeth. But because sandblasting only uses physical methods to remove the deposits on the teeth, it can only restore the original color of the teeth, and cannot turn the teeth white! During the treatment, high-pressure impact on gums with gingivitis will cause slight bleeding.
Type 2: Clinic cold light whitening
Apply high-concentration whitening agent on the tooth surface, and then use cold light to perform the redox catalysis to remove the deposited pigment, and there will be soreness in the process.
Type 3: Whitening at home
It is a whitening treatment used at home. For the first time, the doctor needs to make impressions and make personal dental trays. After the dental trays are made, the dental trays and whitening agents are brought back for the second time. Two hours, a week may be effective.
Type 4: ceramic patch
It is necessary to grind the surface of the tooth to a thickness of about 0.2mm, and then take a mold to make a thin layer of porcelain, and then stick the porcelain to the teeth like a mask. Applicable objects are teeth with severe tooth discoloration and internal staining, or those with poor results after other whitening treatments, such as those caused by severe tetracycline staining.
