A sparkling smile is always considered an asset for somebody’s appearance. To achieve this people try various teeth whitening kits available over the counter to whiten their teeth. Dental bleaching, better known as tooth whitening, is a common procedure in general dentistry but most specifically in the field of cosmetic dentistry. A child’s teeth are usually whiter than the adult teeth.
With growing age the adult teeth often become darker due to changes in the mineral structure of the tooth, and the enamel becomes less porous. Teeth also become stained by bacterial pigments, food-goods, and tobacco intake.
Apart from that some antibiotic medications may also cause teeth stains or a decrease in the brilliance of the enamel. The American Dental Association has mentioned various options to whiten one’s teeth that comprise of in-office bleaching used by a professional dentist; at-home bleaching; over-the-counter and also non-dental options offered at mall kiosks, spas, salons, and other similar places.
Commercial whitening products meant for home use include gels, chewing gums, rinses, toothpastes, among others. The ADA has published a list of acknowledged over-the-counter whitening products to help people choose suitable whitening products.
There is also the choice of effectively and naturally whitening one’s own teeth by natural teeth bleaching process. The ADA advises that prior to any whitening procedure, that one should have one’s teeth checked by a dentist. There are two main methods of gel bleaching—one performed with high-concentration gel and another with low-concentration agents.
High-concentration bleaching can be accomplished either in the dental office, or at home. Any procedure at home is accomplished using high-concentration carbamide peroxide, which is easily available online or in dental stores and is much more cost-effective than the in-office procedure. Whitening is performed by applying a high concentration of oxidizing agent to the teeth with thin plastic trays for a short period of time, which produces quick results.
The application trays should be well-fitted to retain the bleaching gel, ensuring even and full tooth exposure to the gel. Trays will typically stay on the teeth for about 15–20 minutes. Trays are then removed and the procedure is repeated up to two more times. Most in-office bleaching methods use a light-cured protective layer that is carefully painted on the gums and papilla to lessen the risk of chemical burns to the soft tissues. Low-concentration whitening is far less
use a light-cured protective layer that is carefully painted on the gums and papilla to lessen the risk of chemical burns to the soft tissues. Low-concentration whitening is far less efficient, and is generally only performed at home.
Low-concentration whitening involve purchasing a thin mouth guard or strip that holds a relatively low concentration of oxidizing agent next to the teeth for as long as several hours a day for a period of 5 to 14 days. A typical course of bleaching can produce improvement in the cosmetic appearance of most blemished teeth. However, some stains do not respond to bleaching.
Bleaching is most effective with yellow discolored teeth. Though there is a wide range of teeth whitening kits and techniques available, the results after using them may vary from very positive results to almost non-existent results.
