With the development of aesthetic and restorative materials in dentistry, many color, shape and position disorders can be easily resolved. Bleaching of discolored teeth is cheaper, more practical and harmless compared to other restorative methods.
Teeth Whitening (Bleaching) Methods
Teeth whitening (bleaching) methods are collected in three main groups:
1) Chemical Teeth Whitening
2) Photothermal Teeth Whitening
3) Photochemical Teeth Whitening
Chemical Teeth Whitening
In this technique, tooth whitening gel is applied to the teeth with the help of specially made tooth molds. However, it should be noted that chemical teeth whitening technique may have some negative effect on tooth enamel. These chemicals, which can also be sold among various cosmetic products, must be used under the supervision of a dentist.
Photothermal Teeth Whitening
In this method, a certain amount of special gel is also used. However, unlike the previous method, it is applied with the help of a special high-energy beam. The light source may consist of a series of LEDs or a diode-laser. Again, this method should be done under the supervision of a dentist, as there may be possible negative effects.
Photochemical Teeth Whitening
In this method of teeth whitening, the whitening gel is activated using a UV-lamp (blue light) or a KTP laser (green light). The feature that distinguishes this method from others is that the light source used also has a tooth whitening effect (photooxidation). This application provides a deeper whitening on the teeth. When using UV-Light, the surrounding tissues (lips, gums, tongue, etc.) should be well protected against possible burn injuries. There is no risk of burning when using the KTP laser, but the gums must be protected against leakage of the whitening gel (gingiva block). A great advantage of whitening with KTP laser is; As a result of extensive scientific research, side effects on tooth enamel have not been observed. Fluoride application after teeth whitening strengthens tooth enamel and prevents decays.
