Many people are accustomed to health knowledge and health knowledge, in fact, are wrong, not only not conducive to health, but will cause great harm to the body. One minute a day will take you to correct your wrong habits, get out of the misunderstandings, and be healthy.
Teeth generally do not turn white after cleaning. Scaling is through ultrasonic scalers or manual cleaners to remove plaque, soft scale, tartar, pigments, etc. on the surface of teeth. Healthy teeth are not the white most people think, but yellowish.
Changes in tooth color are caused by both endogenous and exogenous factors.
Endogenous factors include: tetracycline teeth, fluoride teeth, etc., which are changes in the color and structure of teeth during tooth growth and development due to taking tetracycline drugs or excessive fluoride content in regional water sources. In addition, pulp inflammation leads to pulp necrosis, and the color of the tooth will gradually turn gray-black; As we age, the color of the dentin deepens and the teeth appear yellow.
Exogenous factors refer to frequent drinking of coffee, tea, smoking, or long-term consumption of deeply pigmented foods, which will cause pigmentation on the surface of the teeth.
For changes in tooth color caused by endogenous factors, scaling is not helpful; For foreign precipitated pigments, scaling can be cleaned.
By cleaning teeth to remove plaque and a lot of pigment, the teeth return to their original color, rather than scaling to whiten the teeth.
