Teeth Whitening Methods Your smile may be the first thing that someone notices about you, and if you want brighter and whiter teeth, there are some things that you may want to know about teeth whitening. Teeth whitening restores the teeth to their natural color, and bleaching whitens teeth beyond the natural color. Teeth may become discolored because of many reasons but there are many home procedures as well as professional procedures that can help you out. Deciduous teeth, or primary teeth, are generally whiter than adult teeth that follow. The reason why teeth change color is that the mineral structure in the teeth changes and also the enamel becomes less porus. Bacterial pigments, various dark-colored foods and beverages, tobacco, acidic foods, and some antibiotic medications contribute to the staining of teeth, as well as microscopic cracks in the enamel from age, and use. Intristic stains are found within the structure of the teeth that may be caused by aging or trauma while extrinsic stains are on the surface of the teeth only. Microscopic cracks also fill with stains and debris, and these millions of cracks in the enamel result from everyday use in chewing. In-Office Bleaching – Cosmetic dentists specialize in teeth whitening, and may use washes, gels, laser light, or a combination of procedures. Teeth will generally be examined and cleaned initially, and tooth color will be discussed, using a shade chart. A cheek retractor is inserted, a hardening resin is painted on the gums to protect them from the bleach, and bleaching gel is applied for 15 to 30 minutes.The hardening gel is rinsed off after 30 minutes and another gel applied. Intense laser light may also be used to activate or enhance bleaching gels. $650 is the cost of treatment for the procedure.

Over-The-Counter Or Dentist Supplied Whiteners – These whiteners are used at home, and can be toothpaste, whitening strips, whitening trays or bleaching pens, and usually contain baking soda, carbamide peroxide, or hydrogen peroxide. Most over-the-counter whitening toothpaste include minor abrasives, which scrub stains from the enamel. The products described above are not as effective as in office procedures unless they are used repeatedly for longer periods.

There are some natural methods that could be used to whiten teeth such as certain vegetables and fruits. The baking soda may be used as a mild abrasive to scrub out the stains. Main risk of teeth whitening is that it may cause damage to the enamel. Using whitening products excessively, or brushing too hard, and too often, may damage the enamel of the tooth, exposing it, which will lead to tooth sensitivity. You should not have your teeth whitened if you are pregnant or nursing, due to the risk of ingesting peroxide. Remember to have realistic expectations of any teeth-whitening procedure.
