After the first whitening at the dentist a tangible result may be obtained.
Before the whitening procedure, the dentist will thoroughly examine the teeth. After determining their condition, the physician will determine whether the teeth are ready for whitening. And he/she will also indicate the reasons for discoloration of the teeth. During the examination, the dentist identifies tooth restorations or fillings. If necessary, he/she can specify which fillings should be changed in case of mismatch of their colour with the colour of teeth after whitening.
Whitening is a painless procedure using a number of whitening agents. The main substance used is hydrogen peroxide. To accelerate and enhance the whitening effect of the teeth, exposure to light, laser or heat is applied. For example, when applying a special gel under the influence of heat, a special substance penetrates into the enamel and dentin, oxidizing the dental pigment.
