Tooth whitening forms an important part of cosmetic dentistry. Tooth whitening is also referred as bleaching, allowing individuals to have a brighter smile. This process helps in the removal of stains and discoloration. There are mainly two types of tooth whitening methods available, in-office and in-home tooth whitening systems. In order to achieve the best and safest results, it is recommended to perform tooth whitening under the supervision of a qualified dentist. In-office tooth whitening systems utilize a combination of bleaching gel and laser light. The process involves the application of the bleaching gel onto the patient's teeth while taking special precautions to avoid the gums and lips. Then a laser light is employed in order to achieve optimal results in a single sitting. In-home tooth whitening systems require the use of dental trays and bleaching gel. The solution used for in-home bleaching is less powerful than the gel used during in-office whitening. The home application of bleach requires four to five sittings, depending on the desired tooth shade. If you opt for in-home whitening, your dentist may provide you with customized trays for your teeth in order to effectively complete the bleaching process. Generally tooth whitening is performed successfully without any side effects. However, if your teeth are sensitive to chemicals, you may experience gum sensitivity for a day or two due to the bleaching agent used. Use of customized trays during in-home bleaching will minimize sensitivity and prevent accidental leakage of the bleaching agent.
