Delivering an aesthetic solution that proportionally complements the patient's neighboring teeth is crucial. In the discipline of cosmetic dentistry, qualities like surface form, translucency, and color are the most important factors for creating esthetic prostheses. The final color of translucent ceramic restorations is determined by many factors such as the thickness of the porcelain veneer, the thickness and color of the luting agents and the color of the underlying tooth structure. In order to the results to be accurate, homogenous, and predictable—all of which are crucial for cosmetic dentistry—color matching must be carried out in a methodical manner. Lighting control at the site, the surrounding environment, state of the teeth, patient positioning, time, and clinician proximity to the tooth, squint test, visual color guidelines, Vita Classical shade guide, Vita Toothguide 3D-Master, Chromascop, customized shade guides, and dentinal and extended shade guides are all considered when mapping shade and translucency. A sensor, a signals conditioner, and technology that allows the conversion of the signals into data usable in the dental laboratory or operatory make up the three components of every color-measuring instrument. Colorimetry, spectrophotometry, digital photography, hybrid equipment, and spectroradiometry comprise a few types of color measurement technology. Both print and electronic shade systems need to be used when choosing the right shade in order to create acceptable aesthetics. The practitioner and patient are both satisfied when the appropriate shade is matched, and the patient also has a more appealing appearance.

Carbamide and hydrogen peroxide are the most frequently utilized compounds for various whitening techniques, that differ as per peroxide level, method of administration, and exposure period, when it comes to the active solutions accessible for important tooth whitening. The 10±1% carbamide peroxide dosage was the only level to date to acquire the American Dental Association's stamp of approval, ensuring its safety and effectiveness for at-home tooth whitening with customized trays. There has been a noticeable growth in the range of in-office tooth whitening compounds commercially available, which typically use elevated carbamide peroxide levels (30 to 37%) with or without an additional illumination. Even though tooth sensitivity appears to be the most frequent side effect of carbamide peroxide bleaching, discomfort goes away when the plan of care is finished. Sensitivity is typically linked to a background of sensitive teeth, greater administration rate, or use of greater carbamide peroxide levels. Additionally, studies have showed that using 10% carbamide peroxide at home to lighten teeth had comparable effectiveness to other methods (over the counter or in-office whitening). Patients generally prefer home vital bleaching with 10% carbamide peroxide to office procedures with 35% hydrogen peroxide. When comparing the safety utilizing 16% carbamide peroxide for nightguard vital bleaching to a placebo or 10% carbamide peroxide, patients receiving 16% reported higher gingival soreness than those administered a 10% carbamide peroxide or a placebo.
