If you cherished this write-up and you would like to obtain additional information concerning 22% carbamide peroxide gel - kindly pay a visit to the site. Dental discoloration occurs mostly in adults due to variations in the teeth's mineral structure, where the enamel continuously loses porosity. Teeth staining can also arise due to bacterial pigments, certain foods and tobacco. Some antibiotics have also been found to cause teeth staining.

    Peroxide is the commonly used ingredient in teeth whitening products. The amount of peroxide in the whitening products, normally 10 to 22%, determines its strength. The effect of peroxide can be a bit corrosive as it works by opening the enamel's pores, thus not all teeth are a candidate of teeth whitening. Teeth with restorations or those that have been bonded with fillings stand low chances of successful whitening as the bonding material always retains its original color. If teeth are whitened the fillings will stand out in a different shade. The only way to achieve a uniform white in this case is to replace the old restorations with those of a preferred color. Natural teeth colors that tend towards brown are also unlikely to produce desired results. Hyper sensitive teeth should not be whitened as it is likely to make them even more sensitive.

    Should your teeth be declared fit for whitening, there are a number of options to choose from. In-office teeth whitening is done by professionals and delivers results in a short time. Teeth are first polished with a grainy material called pumice in order to remove any surface plaque. To keep the teeth dry for the procedure, gauze and retractors are used to restrain the cheeks, tongue, lips and the rest of the mouth and keep them from coming into contact with the whitening solution. The gum line is also protected with a barrier.

    The bleaching agent is applied to the teeth, and a laser or curing light is used to activate the peroxide by adding heat to the solution. According to the brand instructions, it is left on the teeth for 30 up to 60 minutes. It may also be reapplied a number of times in between. Once they attain the desired shade, the teeth are rinsed out with water. After whitening it is advisable to avoid pigmented food and drinks for 24 hours to allow enamel pores to block preventing re-staining. Though this method is expensive it provides instant results.

    Teeth whitening trays and gels are also effective. The trays can be worn a number of hours a day and it can take a number of weeks before results begin to show. Trays and gels obtained from the dentist are custom made and fit your teeth exactly and work faster because of a higher peroxide content. Whitening strips can be bought in chemists and also work. Whitening toothpaste is an option for sensitive teeth which you may want to avoid bleaching. It contains mild abrasives - that remove surface stains. New whitening products have come up in the form of mouthwash and even chewing gum.
