Choosing Between At-home And Supervised Teeth Whitening Procedures All options relating to teeth whitening can be broadly categorized into two. The first group of procedures and options fall under at-home teeth whitening procedures. The next set belongs to dentist-supervised teeth whitening procedures. After this is done, the teeth will then be coated with the whitening formulation, and the coating will cover the surface of the teeth. And depending on the attending dentist, the formulation may contain the hydrogen peroxide or the carbamide peroxide. Either way, it can be expected that the whitening effect can be achieved. There are teeth whitening / bleaching kits that could be had OTC because there are also disadvantages to in-office teeth whitening. Setting an appointment with the dentist aside from finding the time to sit in a dentist's chair and the follow up sessions that are required could be time constraining to other people. On the other hand, no amount of teeth bleaching will whiten teeth more than its natural color. In some cases, it could artificially be done but never recommended. No matter how teeth whitening and bleaching is done, anything involving cosmetic enhancements and restoration is subjective that varies from person to person. In-Office Teeth Whitening Common Procedures to Expect This procedure is also known as power whitening. This is so because in-office bleaching methods have more bleaching concentration than that which is offered over the counter thereby producing faster results. In-office tooth bleaching is also the safest. For these, internal bleaching must be done by a professional. The process is basically the same. A bleaching agent will be placed and sealed inside the tooth that will make its shade lighter given time. Not all teeth are white. The teeth have sixteen varying shades. While a temporary tooth may be sparkling white, the teeth replacing it may be not.
