The results can be realized after a few days, and the white color of the teeth can be maintained for months provided of course that proper maintenance is made. The strips on the other hand are thin strips that are coated with the gel fortified by hydrogen peroxide. These strips are also attached to the teeth twice a day. But this current cost does not stop those who want to have whiter teeth and the practitioners offering this service. Right now, there are dentists that offer these services at reduced prices thus making these services affordable for the bigger set of consumers. Just how much should you prepare when you will select these professional services? The polishing action is important as this will remove the plaque and dirt found at the surface of the teeth. The mouth will then be isolated with the use of the gauze. This is a necessary step so that the teeth will be dry for the rest of the procedure. There will be times when the retractors will be used as well, and this is important so that your lips and tongue will not get in contact with the whitening agents incorporated in the solution. And what are these limitations? Consider the list below, and be guided accordingly. These procedures are not best for those below 16 years of age. The procedures in teeth whitening may compromise the pulp chamber and the nerve of the tooth. And at that stage, the pulp is still enlarged and when done for people of this age then this may only irritate that area. What To Remember When Shopping For Teeth Whitening Paste Many studies have it- teeth whitening pastes that are available in the supermarket works and are safe. And when used properly, say twice daily the expected effect by the person can be realized in as a short as two weeks. And everyone can even increase the chance of being in the safe side if they can shop for the whitening tooth paste that is approved by the American Dental Association. It is not entirely true that using bleaching agents containing such reduces the enamel of the teeth over time. If it does, it is actually very negligible and so does not have adverse effect on the tooth. Sure there could be, in some cases, mild irritation and tooth sensitivity during the initial stages but these usually are gone after a few days of treatment.
