1. What is used to whiten teeth?

Modern teeth whitening is based on hydrogen peroxide. For professional whitening most often use hydrogen peroxide from 25 to 40%. Although there are on sale whitening gels with a percentage of peroxide no more than 6%, but their use does not give a significant result. To activate peroxide use heat: laser or thermal.

2. What are the safest and most effective lamps?

It all depends on the light spectrum of the lamp itself. Ultraviolet or infrared spectra provoke heating of the tooth tissue and soft tissues of the oral cavity and lips. The danger is that it can lead to increased tooth sensitivity or lip burns (especially when using fillers and hyaluronic acid).

It is better to use a lamp with a cool spectrum of light. The basic color that is taken as a basis is blue. On the color spectrum, blue is the opposite of yellow, which is the basis of tooth pigment coloring. It is by far the best choice, as cold light without heat gives the best results.

If the preparation before whitening is done correctly, it does not cause any discomfort at all.

3. Is it possible to perform whitening in beauty salons?

It is important to remember that teeth whitening is a medical procedure that should be performed by a dentist. Only a dentist can evaluate all contraindications and choose the right percentage of peroxide for whitening.

  • — Before the procedure, it is important to examine the oral cavity for carious lesions or inflammatory processes.
  • — It is important to understand the cause of the darkening of tooth enamel and to choose a treatment on this basis. This can only be done by a specialist with higher medical education.
  • — The whitening procedure performed unprofessionally can lead to serious complications in the form of dental tissue disruption, mucosal burns and increased tooth sensitivity.

4. Does tooth sensitivity increase after whitening?

The higher the percentage of peroxide, the better the result, but also the greater the risk. Since a high percentage of peroxide is used for whitening, it is impossible to guarantee that sensitivity will not occur. Even with a low percentage of peroxide, sensitivity can occur.

5. What to do with fillings during whitening treatment

It all depends on the size of the filling. If it is a small part, you can try whitening. If the filling occupies a significant part of the tooth, it is better to refuse whitening as the filling will not change its color and may get a stained effect. Of course, if you are determined to whiten, the filling can be replaced after the procedure, taking into account your new color. Dentists who do aesthetic dentistry and restoration of teeth will give you a detailed consultation and choose the best solution for your problem.

6.How long does the whitening last?

You will not be able to undergo this procedure for at least a year. If you follow the doctor's recommendations, you won't even need it. The effect after whitening can last for more than three years.
