Teeth whitening, a new method of three kinds of people born in the 1970 s, in this life are likely to the tetracycline class of antibiotics, because in those days people didn’t know that children should be careful with tetracycline class of antibiotics, if which child happened during right too much with these drugs, there will be a yellow, brown or film of tetracycline teeth.
“Pigmented teeth such as tetracycline teeth are a common oral disease that can occur in people of all ages.”
Chu Jinpu introduced that there are two main reasons for tooth coloring (not white) : first, endogenous coloring, which is mainly caused by the influence of internal or systemic factors of the human body during the growth and development period or after the eruption of the tooth, leading to changes in the hard tissue structure of the tooth and permanent changes in the color of the tooth.
For example, tetracycline teeth, dental fluorosis, etc. are caused by the children’s ingestion of a large number of tetracycline antibiotics or excessive fluoride before the age of 8, leading to changes in the structure of dentin and tooth enamel, resulting in no light, yellow or gray black tooth surface.
Second, exogenous coloring, mainly external factors or local environmental changes in the mouth, resulting in tooth discoloration.
Pigments found in cigarettes, teas, drinks, foods and medicines tend to deposit and stick to the surface of teeth, obscuring their normal color.
“Ultrasonic cleaning or manual cleaning (commonly known as tooth cleaning) can restore the normal color of exotically colored teeth, but it is difficult to cosmetically repair endoscopically colored teeth such as tetracycline teeth.”
In the following, Chu Jinpu introduced several cosmetic repair methods of endogenously colored teeth: bleaching bleaching method will be applied to the colored teeth, so that the teeth are partially or completely colored, medically known as tooth bleaching bleaching method.
Currently, hydrogen peroxide (30%) and peroxyurea (10% to 15%) are commonly used as bleaching agents.
Composite resin masking is a technology that has been developed gradually since the 1980s. It is a polymer composite resin with natural tooth color that is fixed on the surface of the colored tooth to restore the normal color of the tooth.
For the severe tetracycline teeth with dark color and enamel defects, it is difficult to achieve satisfactory results by bleaching and decolorization method and composite resin covering method. The best choice is porcelain full crown or veneer restoration.
“Having white teeth is everyone’s dream, so when people hear there is a way to whiten their teeth, they want to try it.
There are many factors that cause tooth coloring, including local factors, systemic factors, exogenous factors and endogenous factors. Patients with tooth coloring must see a doctor as early as possible, and the doctor must find out the cause of tooth coloring, so as to carry out targeted treatment.”
Don’t delay your illness by using products advertised to whiten your teeth, Dr. Chujip warns.
