What is tooth whitening?
Whitening is the change of the color of the natural teeth to the brightest and whitest, which is done only by the dentist with various techniques.
Teeth whitening techniques
- Bleaching at home by the patient, but always with the supervision of a dentist. In this technique, the dentist manufactures two personalized splinters of very thin transparent plastic material that apply as a glove on the teeth, one for the upper jaw and one for the lower jaw. It is given to the patient along with the whitening medication, and depending on the peroxide content of the drug, patients may use it 1 hour a day or twice a day for half an hour each time, even at night. All this has to do with how discolored the teeth are, the patient’s sensitivity, how fast the patient wants to have white teeth and other factors. This is why you always need the supervision and guidance of a dentist. The bleaching gels used in this case are hydrogen peroxide and carbamide peroxide with a content of 3% – 20%. Generally, the longer you hold a strong material in your teeth, the more white they will become. However, this should not be the case with dental whitening, because the higher the percentage of peroxide in the bleaching gel, the shorter the stay in the teeth should be, as holding the gel for longer will lead to dehydration and increase teeth sensitivity.
- Whitening at the dental office by the dentist. It is as effective as the previous one, but it is done in less time. It takes one or two sessions within 10 days of each other. Each session lasts one to one and a half hours. One of the benefits of whitening in the office is that the dentist checks all the teeth and sees if they really need whitening or not, examines whether the discoloration and stains are due to stains and not tooth decay or other more serious problems requiring other types of treatment. . The Dentist checks for spots that should not be whitened and protects them to avoid hypersensitivity and pain later on. Whitening of this type is done by activating the gel with some light source, such as plasma, Led and laser, or by activating the gel chemically without a light source. The bleaching gels used in this case are hydrogen peroxide and carbamide peroxide with a content of 15% – 45%.
- Mixed bleaching in the dental office and at home. This bleaching method is usually used in difficult and demanding cases, with intense discoloration and in patients with high aesthetic standards.
Which teeth are bleached?

How does tooth whitening work?
Bleaching is done by applying some bleaching gels on the teeth. It affects the brightly colored organic molecules that appear between the enamel hydroxyapatite crystals or the boundary between enamel and dentin and degrade them, thereby removing them from the enamel. It is these organic molecules that give the teeth a stained appearance.
For superficial staining of teeth, apply the bleaching gel for 30 to 60 minutes on the surface of the tooth.
However, for deep stains starting from the inside of the tooth, such as in the case of non-vital or decayed teeth, the bleaching gel has to be inserted into the pulp chamber and the root canal several times, that is, the tooth should be opened and the material placed inside. This should be repeated two or three times a week. The bleaching process continues until these organic molecules are completely discolored.
The whitening process works best and whitens the teeth when the pigments are yellow or brown. When the teeth are gray, they are difficult to bleach.
Can I eat and drink what I want during whitening?
It is advisable to avoid certain foods during the bleaching process that have many pigments. These foods are black tea and in general beverages, coffee, energy drinks, red and white wine, soy sauce, balsamic vinegar, cola soft drinks, and finally red fruits and vegetables, such as cherries, strawberries, black berries, red grapes etc.
Is bleaching painful?
Bleaching is mostly a painless process, but sometimes teeth sensitivity can be created because they can be corroded, have exposed roots, have deep and many cracks, and at times some patients have very sensitive teeth.
Many times patients use the gel for more than the accepted time, not following the dentist’s instructions or putting too much gel on the splints they use in the bleaching process at home, resulting in gum sensitivity. Then what can be done from the patient is to take a painkiller, to interrupt the procedure for a couple of days or to reduce the concentration of the bleaching agent and to consult a dentist in general.
Will the white dental fillings, crowns and bridges on my teeth whiten whiten?
Bleaching is a process that only concerns the natural human teeth, so anything artificial, such as dental fillings, bridges, crowns, is not affected by the bleaching agent at all. This is why it is best to whiten the teeth first and then replace the old dental, bridges and crowns based on the color of the natural teeth.
Will bleaching wear my teeth?
No, whitening does not harm the dental tissues once an experienced dentist has followed the whitening protocol. Research to date has shown that it is a safe and harmless method for teeth, as long as teeth and gums are healthy. In general, whitening is a safe process because the chemicals used to neutralize the chromogenic organic molecules do not substantially affect the structure of the tooth itself. Only some minor side effects can occur, such as some tooth sensitivity, but this is also overcome because the dentist takes care of both the exposed root and gum as well as very worn teeth which dentin is uncovered by enamel.
– Follow the dentist’s instructions strictly.
– Do not exaggerate either the amount, because it burns in the gums, or the duration of bleaching, as you may overly dehydrate the enamel and thus become chalky and can become crumbly.
