Teeth whitening: different techniques to get a perfect smile

Tooth whitening is one of the most common procedures that are done in general dentistry.  However, it is even more common in the specialized area of cosmetic dentistry.  Tooth whitening is also sometimes referred to as dental bleaching.

During the younger years of a person’s life, his teeth are usually whiter than the adult teeth that will come later.  Then, as the person goes through more years, the teeth become even darker due to a variety of reasons.  The tooth’s mineral structure changes with age causing it to change in color.  Furthermore, all the food that the teeth chew on over the years also affects the color of the teeth and stains them.  Tobacco and some medications can also make the enamel of the teeth become less porous thereby reducing the brightness and whiteness of the teeth.

There are many ways to whiten the teeth.  The first one of course is to have your teeth whitened professionally by a qualified dentist.  The second one is the do-it-yourself method where you can whiten your teeth using over the counter teeth whitening products in your own home.  The third method is by using non-dental methods to whiten your teeth.  These services are often offered in malls or in kiosks, salons, or spas.  Do-it-yourself teeth whitening products are usually in the form of gels, toothpastes, and gums.  There are lists of teeth whitening products published by the appropriate associations that are available to help do-it-yourselfers choose the best product for their use.  One important reminder though, even if you intent to try to whiten your teeth yourself, it is recommended that you still have your teeth checked by your dentist before attempting to do so.  Having your teeth checked can help you determine if you are allergic to any of the tooth whitening products that are available on the market.

In terms of gel bleaching, there are 2 main methods to choose from: high concentration bleaching and low concentration bleaching.  High concentration gel bleaching is the method usually employed in dental clinics but it can also be used in the home.  For home use, high concentration bleaching is accomplished with the use of carbamide peroxide.  This is a high concentration teeth whitening gel that is easily available at any dental store or even in online stores.  Using this gel makes teeth whitening at home a lot more cost effective than having it done at the dentist’s office.  The whitening procedure is performed with the help of plastic trays containing the whitening agent that is applied to the teeth.  It is very important then for the plastic trays to be well fitted onto the teeth to prevent them from falling off and to make sure that the teeth are whitened evenly.

Teeth whitening using low concentration gel bleaching agents on the other hand are a lot less effective than using high concentration gel bleaching agents.  This method is rarely used in dental clinics and is therefore generally used by people at home.  Because the concentration is low, these gels usually need to be applied to the teeth for several hours at a time and for several days in a row.
