Los Angeles, CA (PressExposure) July 15, 2009 -- The practice of teeth whitening is one of the most popular forms of cosmetic dentistry. This practice involves few methods on how to effectively whiten our teeth through the use of over-the-counter (OTC) whitening products and in-office procedures. OTC teeth whitening products are generally composed of teeth bleaching gels (low and high concentration) and other whitening agents like tooth pastes. In-office teeth whitening procedures typically involves the use of both teeth bleaching gels, particularly the high-concentration gels, and laser bleaching. So which of these is the best when it comes to teeth whitening?
At-home/OTC teeth Whitening Products
At-home whitening are usually done by using thin guard trays or by applying small strips that go over the front teeth. According to the cosmetic dentist hollywood [http://www.alhambradental.com/blog], oxidizing agents such as hydrogen peroxide or carbamide peroxide are used to lighten the shade of the tooth. There are two types of bleaching gels that anybody could use, the low-concentration and the high-concentration gels. The difference between the two is that low-concentration takes days of repeated use before actually seeing the difference whereas high-concentration produces quick results. The main disadvantage with using high-concentration gels is that it could cause chemical burns to soft tissue if improperly applied.
Other whitening agents
Various chemical and physical agents can be used to whiten teeth. Toothpaste typically has small particles of silica, aluminum oxide, calcium carbonate, or calcium phosphate to grind off stains formed by colored molecules that have lodged onto the teeth from food. Unlike bleaches, whitening toothpaste does not alter the intrinsic color of teeth.
In-office Teeth Whitening Procedures
Aside from being used at-home, bleaching gels are also used by dentists. The difference is that in-office provides professional assistance when applying bleaching gels, particularly with the use of high-concentration gels. According to the cosmetic dentist hollywood [http://www.alhambradental.com/blog], whitening is potentially better at a dentist because with teeth whitening done at home, the strip or mouth-guard does not completely conform to the shape of the teeth, sometimes leaving the tips of the teeth (near the gumline) unbleached. The bleaching agent is typically less than 10% hydrogen peroxide equivalent, so irritation to the soft tissue around teeth is minimized. Dentists as well as some dental laboratories can fabricate custom fitted whitening trays that will greatly improve the results achieved with an over-the-counter whitening method.
Laser bleaching, also known as power bleaching, uses light energy to accelerate the process of bleaching in a dental office. Different types of energy can be used in this procedure. An argon laser is preferred over the use of an arc lamp (the traditional dental method of light-activated bleaching) or infrared laser because it does not exhibit any of the heat or UV ray emissions of the arc lamp. Getting a chemical burns, which is occasionally a side-effect of gel bleaching, or heat-induced sensitivity, is not a factor with argon laser whitening.
