Who doesn't want white teeth? Teeth whitening has become one of the first requests that dental patients have when visiting their dentist.
Whitening is defined as any process that can make teeth appear whiter, and most of whitening is accomplished through a product that causes an intrinsic change to the tooth enamel, rather than surface stain removal.Laser teeth whitening may be an option available at your dental office, but the treatment is not for everyone. Product safety and efficacy is paramount for a good result with little to no side effects.
Your Choices
Tooth whitening or bleaching is the most cost-effective and least invasive procedure that can improve your smile. However, according to a statement by the American Dental Association (ADA) on tooth whitening, these procedures are not without contingencies. It is recommended that any method be supervised by your dentist after the dental exam that determines your best option for whitening. The condition of your teeth and the cause of the discoloration will do just that. Your choices include products purchased by the patient for home use, materials provided by the dentist for home use or procedures performed in the office.
Laser Procedure
Laser teeth whitening is administered in a dental office exclusively, and is the most expensive method for whitening. Bleach is applied to each tooth, and heat generated by a laser enhances its effectiveness while ultimately speeding up the process. This procedure uses a strong bleaching gel that the laser activates and enhances for quick, dramatic results.
The Indian Dental Association explains that traditionally, at-home whitening is done with bleaching gel which is applied to the teeth using thin guard trays. Oxidising agents such as hydrogen peroxide or carbamide are utilised to lighten the shade of the tooth. With these high concentrations, special precautions are taken to reduce tooth sensitivity, as well as protect the lips, gums and other oral tissues from being damaged. They include:
- cheek retractors
- formulated soft or rubber dams to cover gum
- desensitising pastes which can help strengthen and harden enamel and
- professional application of fluoride or similar desensitising product
