Teeth whitening is preferred by people whose teeth become discolored due to different reasons over time. Aesthetically, the appearance of the teeth plays an important role in the physical appearance of the person. People whose teeth have lost their natural whiteness may lose their self-confidence and be ashamed of their smile, even if they do not experience serious health problems. In this case, with the teeth whitening process to be applied, people regain their healthy and happy smiles. The teeth whitening process, which is applied to make existing teeth look whiter, is also known as blenching. Genetic factors, dietary habits, smoking and coffee consumption, and external factors that develop later lead to yellowing in the color of the teeth. Sometimes even regular oral care and brushing is not enough to maintain the whiteness of the teeth. Teeth that have lost their whiteness may become even whiter than before after the procedure.
