Tooth Whitening Process

By Jake Wakefield

Dental bleaching, also known as tooth bleaching, is a common process in common dentistry but most especially in the area of cosmetic dentistry. A child's deciduous teeth are generally whiter than the adult teeth that ensue. As a person ages the adult teeth often become darker due to changes in the mineral structure of the tooth, as the enamel becomes less absorbent. Teeth can also become discolored by bacterial pigments, foodstuffs and tobacco. Particular antibiotic medications (like tetracycline) can in addition lead to tooth stains or a drop in the brilliance of the enamel.

Whitening is not a quick fix but it is one of the least costly options with the whole procedure consuming around 3 - 4 weeks. Lightening is least working if teeth have white spots, decomposed or infected gums. Bleaching is not recommended in children under the age of 16. Whitening is most effective with yellow discoloured teeth. Decolouring solutions may be employed directly to the teeth, embedded in a plastic strip that is set on the teeth or use a gel held in place by a mouth guard.

The teeth can also stain and darken with the use of tobacco, bacterial pigments and different foods. Many people will use a teeth whitening treatment that uses an oxidizing agent. A good example is hydrogen peroxide. It's just like putting peroxide on the hair to bleach it, but it's put on the teeth in order to lighten them. It should be noted though that they are not the same kind of peroxide; there is one that is made specifically for use on the teeth.

Internal staining of dentin can tarnish the teeth from inside out. Internal bleaching can resolve this. If serious staining or tetracycline damage is here on a patient's teeth, and bleaching is ineffective, there are alternative methods of whitening teeth. Bonding, when a thin covering of combination material is applied to the front of a person's teeth and then cured with a blue light can be performed to disguise the staining. A veneer can also mask tooth staining.

There are two central methods of gel bleaching-one performed with high-concentration gel, and a further with low-concentration agents. High-concentration bleaching can be accomplished either in the dental office, or at home. Carrying out the process at home is accomplished using high-concentration carbamide peroxide ,which is easily accessible online or in dental supplies and is much more cost-effective than the in-office method.

A teeth whitening treatment can last a long time, but will be shortened by excessive coffee and tea consumption and heavy cigarette smoking.

Generally in-office bleaching measures use a light-cured protective layer that is carefully painted on the gums and papilla (the guidelines of the gums connecting the teeth) in order to cut the risks of chemical burns to the soft tissues. The whitening agent is either carbamide peroxide, which dissolves in the mouth to form hydrogen peroxide, or hydrogen peroxide itself.

Teeth bleaching is a highly effective way of bleaching the natural colour of your teeth without withdrawing any of the tooth surface. Tooth lightening is a well-established process in cosmetic dentistry. Teeth whitening is ideal for anyone looking for immediate results and will lighten your tooth up to 6 shades from your natural colour in only 45 minutes. Teeth whitening is actually a teeth bleaching procedure, which lightens discolourations and discolourations on the teeth enamel and dentin. - 29879
