Frequent consumption of certain products contained the different kinds of chemical compounds affects on the colour of teeth, especially on prosthetic restoration timbre. A very interesting issue is to determine the effect of exposure in some of the commonly used chemical substances on dental restorations colour change. The study was conducted on the upper crown of the tooth, namely the first incisor. The colour evaluation change has been made using a spectrophotometer SpectroShade, which determines the amount of light absorbed by the element over the entire visible spectrum 380 - 720 nm. In the paper was shown that long-term use of products that contain chlorhexidine can lead to permanent color change of ceramics dental materials. After long exposure in the solution the ceramic became lighter but their hue value indicates that the color is closer to yellow.
