While the deciduous teeth of children are basically whiter than their subsequent adult teeth, adult people’s teeth generally become darker because of the changes in the teeth’s mineral structure. The basic purpose of tooth whitening is to bring the teeth to their original white shade as closely as possible. Generally, teeth eventually become stained by bacterial pigments, natural color pigments from food, and with vegetables that are rich in xanthonoids or carotenoids. The brilliance of the teeth enamel is also considerable reduced and teeth stains ensue due to some antibacterial medications such as tetracycline. Color-rich liquids such as red wine, tea, cola, and coffee are also known to bring teeth discoloration. Oxidation ReactionReduces Stains Tooth whitening methods can safely and quickly remove the unsightly stains on teeth with the least discomfort. The process initially addresses the existence of the pellicle film that accumulates over the teeth’s enamel layer. This film, made of foreign material that comes from coffee, cigarette smoke, food, etc., penetrates deep. The dentist removes this film through chemical treatments and scraping. For some DIY, you can scrub off some of this film with an abrasive toothbrush and awhitening toothpaste. Tooth whiteners contain chemical agents such as hydrogen peroxideand carbamide peroxidethat soak into the tooth enamel and produce an oxidation reaction that destroys the stains. Coating Covers Stains Another method that masks teeth stains is teeth bonding that improve a person’s smile. With this method, a thin coating made of tooth-colored resin compositematerial made of durable plastic is layered over the front of the teeth. The coating is then cured and hardened with the use of a special blue light. This process “bonds” the resin material to the teeth. The dentist chooses a resin composite shade that closely resembles the color of the person’s tooth. The tooth surface is roughened before applying a conditioning liquid. The tooth-coloredresin putty is then applied to the tooth, molded to fit the shape closely, and smoothed for evenness. To harden the resin material and bond it to the tooth, a laser or ultraviolet light is used. Easy and Fast Dental Procedure Teeth’s bonding is an inexpensive and easy cosmetic dental procedure. The process can be accomplished over one dental visit. On the other hand, crowns and veneers need to be customized and manufactured. Only a minimal part of the tooth enamel is removed for the bonding procedure, as compared to crowns and veneers. Dental bonding is best for small cosmetic corrections or for temporary improvement of cosmetic defects. Even if bonding materials are not as durable as the other restorative processes, they are still proven to be stain resistant, though not as capable of resisting stains as well as crowns do.
