It often happens that we see that our teeth change color in time and become darker. The cause of these changes can be various. Tooth decay is affected by bad habits such as smoking. Then, too much color contributes to the consumption of food and beverages that contain very intense pigments (black coffee, red wine, etc.). One of the causes is age. The teeth are consumed throughout life, especially tooth enamel that is located on the surface of the teeth and gives the tooth a beautiful white color. A deeper layer of teeth, called dentine, which is yellow, scrub through the worn and thin enamel. To restore whiteness to our teeth, we try to aesthetically treat teeth. Whitening procedures should be performed exclusively in the dental clinic, it is very simple, painless, and does not damage teeth. Procedure begins with professional removal of hard and soft stains from the teeth and the cleaning of teeth from all impurities. Then the gums (gingivae), facial and lips protection is performed, and then a peroxide based bleaching gel is applied to previously cleaned teeth. The bleaching is done in one shade, and it takes 30-45 minutes, depending on the degree of whiteness we want to achieve. After completing the treatment, teeth become brighter for 2-3 shades of natural color.br>
The dental prosthetics is a compensation for lost teeth and restoration of aesthetics, function and better health of our organism . In prosthetics we distinguish mobile and fixed prosthetics. Mobile prosthetics means the creation of mobile prosthesis (removable dentures). Depending on the number of missing teeth, dentures can be partial and total . Fixed prosthetics involves the compensation of one or more lost teeth by making crowns (covers), and bridges on existing teeth or on healthy roots of broken teeth or implants, and their permanent cementation (not removable) . There are metal ceramic, zirconium ceramic or pure ceramic crowns . Today, we give priority to non-metallic ceramics because of its biocompatibility and aesthetic superiority. Due to the computer technology (CAD / CAM), superior precision is achieved. By non-metallic ceramics we avoid possibility of occurrence of the dark edges that we encounter when we deal with metal-ceramic crowns (due to marginal shine of metals). There is no possibility of corrosion and release of metal particles. There are several types of non-metallic ceramics (eg e-max, empress, zircon ...). Given its composition and properties, as well as the method of production, each has its own indication.
