There are several ways to beautify teeth:
First, tooth bleaching.
Tooth bleaching is also called tooth bleaching. This technique is a method of using oxidant or acidic corrosive agent to eliminate excessive pigment in hard tissue of teeth and make teeth shallower. During the treatment, the doctor applies a decolorant to the tooth surface to remove the pigment from the hard tissue of the tooth. This method is called in vitro bleaching. This method is mainly suitable for moderate defect-free fluorosis and decoloration of tetracycline teeth.
Second, whitening teeth by oxidation
Oxidative tooth whitening refers to the method of adding proper amount of ether into 30% hydrogen peroxide to make tooth whitening agent, smearing it on the surface of teeth that need whitening, and lightening the color of teeth by laser, infrared radiation or heating.
When treating with this method, the doctor will make a thin plastic tray for you, teach you to take off the tray yourself, drop whitening agent into the tray, and let you wear the plastic tray with whitening agent dripping at night to realize the slow bleaching of your teeth. This technique has fewer visits and can bleach multiple teeth at the same time. Generally, satisfactory results can be obtained in three to five weeks. If there are symptoms such as tooth allergy and chewing weakness during bleaching, bleaching should be suspended until the symptoms are relieved. The types of oxidants, the causes and extent of tooth coloring and its sensitivity to bleaching agents, as well as bleaching time and dosage, all have effects on tooth whitening effect.
Third, acid etching whitening teeth.
Tooth whitening by acid etching is a method in which the concentration of 18%-36% hydrochloric acid is used as the main body to make a tooth corrosive agent, which is applied to the surface of teeth that need whitening to decalcify and dissolve the enamel surface to remove the pigment, and then the teeth are remineralized with 10% calcium gluconate mineralized solution. Acid etching is mainly used for dental fluorosis. There are also cases where the pigment on the surface of colored teeth is 0. 1-0.2 mm thick and then it is etched and remineralized by acid. Acid corrosives will not only corrode oral soft tissues, but also corrode hard tissues of teeth. Therefore, this method is dangerous and should be used under the guidance of a doctor.
Four. Tooth bleaching
Intradental bleaching refers to a kind of tooth cosmetic method that bleaching drugs are placed in the pulp cavity to eliminate the pigment in the hard tissue of teeth and lighten the color of teeth. It is suitable for patients with abnormal tooth color whose pulp is inactive. Intradental bleaching is not suitable for patients with abnormal color of vital pulp teeth, because pulp bleaching requires the use of pulp cavity, and it is not advisable to remove vital pulp in order to improve tooth color.
Verb (abbreviation for verb) tooth whitening by shading
Color masking method refers to smearing or pasting dental materials with good color and close to nature on the surface of teeth to cover up the bad tooth color of original teeth and reveal the color of restoration materials. Color masking is suitable for patients with severe congenital tooth color abnormality or acquired disease.
There are many methods of dental cosmetology, each of which has its own specific adaptive population, and not every method is effective for anyone. Therefore, before dental cosmetic surgery, we should communicate with doctors to determine the most suitable method for dental cosmetic surgery. May everyone have a good white and shiny tooth!
