White teeth throughout the whole year

White teeth throughout the whole year

The bright smile always was and also will be very attractive. There are still people who try some home tricks. You have to be very careful because your enamel could be damaged with it. Whitening is a common treatment almost in every dental clinic. It is the easy procedure performed by dentist and dental hygienist.


The success of whitening could be influenced by an initial state of teeth and also by not treating defects. All decays have to be cured before the whitening, because of the fact that whitening liquid could penetrate into the tooth through a decay space. If you have caries or receding gums, the process of whitening can cause sensitivity of teeth. Before the whitening, dentist checks the total state of the oral cavity. Then the dental hygienist makes a cleaning. Bacterial film, food rests and other substances are removed. It all contributes to a color change of your teeth. If all the procedures are done, the whitening could start.


  1. Ambulant whitening
  2. Combined whitening - (combination of ambulant whitening and self-home whitening)

All these methods are based on hydrogen peroxide and its lighter form called carbamide of peroxide. These liquids make your teeth whiter. Oxidative part of peroxide penetrates pores of the crystalline structure of enamel and decomposes pigments. Whitening gels are applied right at the surface of the teeth. The amount of the hydrogen peroxide in a form of carbamide of peroxide is around 1/3 which means that the gel in a concentration of 15% is the same as a 5 % hydrogen peroxide.

Ambulant whitening 

It usually requires only one appointment at the dentist. This procedure has to be done under the control of qualified professional because the gel could have various concentrations of hydrogen peroxide. To prevent your gums from chemical burns it is necessary to use a special protective gel.

Combined whitening

Obviously even a name of this type of whitening says that it is a combined method. The first part you do at home by yourself and second part is the ambulant whitening to highlight and stabilize the final effect. It is considered to be the most effective, the most stable and the most safe method. Another advantage is possibility to fresh your bright smile at home every time you want. Splints and whitening gels are yours.


There is only a low probability for any problems to appear. Some people could have temporary sensitivity of teeth. In the case splints do not fit properly, gels could leak out and burn your gums.

Cases when the whitening is not effective

There are some cases when teeth are not recommended for whitening. For example: teeth after an accident (tooth with a nonvital tooth pulp), serious forms of tetracycline teeth or fluorosis. The whitening can change only a color of natural structures of teeth. Fillings, crowns and bridges do not change.

It is advised to undergo whitening under the control of your dentist. He or she can indicate the most appropriate type of the esthetic whitening.
