Dental whitening is the procedure through which the stains and discolorations are removed from the teeth. Of course it depends on the type of stains what procedure will the dentist use. For extrinsic stains (stains that are caused by food and drinks), he might use laser teeth whitening.
For the intrinsic stains which are basically caused by “internal” factors, such as the discoloration of the teeth because of certain medications, there is really no final solution available. In most cases, when you stop taking the respective medication, the teeth might revert back to their original color. Or, you can choose dental veneers to enhance aesthetically the teeth.
Patients who struggle with heavily stained teeth, will most probably go though dental scaling and polishing, and if the desired results are not achieved then a dental whitening procedure will also be performed.
Both home dental whitening kits and whitening in the office is based on a special process where peroxide bleaching gel is used. The difference is that in the office the dentist will use a bleaching gel with a higher concentration of peroxide. For safety reasons, the home kits use a lower concentration of peroxide. When a gel with high peroxide concentration is used, there are many risks for side effects possible such as dental sensitivity, or injury to the tissues within your mouth, gums and even the lips).
Laser dental whitening is the most popular in-office procedure. In order to whiten your teeth, the dentist will use the special gel and then activate this gel with the help of a light, to whiten your teeth. The procedure lasts for maximum 2 hours, and you will leave the dental office with beautiful, white teeth. In most of the cases, dentists suggest that after laser dental whitening, the patients will use periodically a home whitening kit to maintain the whiteness of the teeth for much longer.
Before dental whitening, it is important to:
-get the needed dental work- cavity fillings, dental bonding, any crown work, etc. This way, with laser whitening all your teeth will have the same hue of white. If you first whiten your teeth and get dental work done afterwards, there will be differences in the color and shade of your teeth
-the dentists perform a professional dental cleaning, removing all tartar deposits and surface stains
The dentist will always isolate your lips and gums, so that they will not come in contact with the strong peroxide gel of 6% concentration. Since the home dental kits have got a very low concentration of peroxide, there is no need to protect your mouth tissues, because there is no risk of injury such as burning for example.
You need to be extremely careful because online there are sold some dental whitening home kits with a very high concentration of peroxide. You should never purchase such kits, only the ones that are pharmaceutically approved and tested to be safe.
