Teeth whitening is a way to restore the natural colour of teeth with applying a chemical agent that oxidizes the organic pigments of the hard dental tissues. Teeth whitening has become one of the most frequently requested dental procedures among the population. The public demands whiter, more perfect smiles, and many teeth whitening options have been made in response. To assess the changes occurring in the hard dental tissues, and, in particular, in the enamel, it is necessary to study the chemical structure of the teeth and determine the number of elements in the enamel to predict the whitening procedure outcomes and make adjustments in post-procedural care. The aim of this study was to investigate the changes in the chemical composition of the dental enamel surface after the procedure of professional hygiene and the use of 35% hydrogen peroxide for teeth whitening as the main chemical component of the whitening system. To study the trace element composition of the dental enamel, the tooth surface was segmented into areas for microanalysis. The peculiarity consisted in that the studied areas differed from the right and left sides of the tooth, because the left side in the studied teeth was the control area, and the right side allowed us to compare and contrast the chemical component of enamel in each tooth separately, by comparing the findings. The results obtained have demonstrated that there is a change in the chemical composition of the enamel in the studied teeth. The change in chemical composition indicators significantly affects the change in clinical indicators, and the strength of clinical manifestations will depend on the features of functional and structural resistance of the dental enamel. We can state that changing in the number of elements can lead to increased sensitivity during the rehabilitation period throughout which the chemical composition of the dental enamel restores.
