Bright, healthy teeth go a long way in making a strong first impression. That is why it is no surprise that so many people are turning to teeth bleaching to improve their smiles. Whitening is one of the least expensive and effective cosmetic remedies available to enhance a faded smile. It can be done at home or at your dentist’s office, using a variety of products and techniques. It is important to note. even if you are only considering an at-home whitening approach, it’s best to have a dental exam first to make sure your discoloration is not due to a condition in need of treatment. Your dentist can also help you choose the most effective whitening method for your particular situation.
Whitening involves applying bleach solutions to the teeth. The bleach attacks the highly colored organic molecules that lodge between the crystals of tooth enamel (the outermost tooth covering) or in the dentin (the tooth material under the enamel).Bleaching works best on yellowish stains and even some brown stains, but may not work at all on gray discoloration. It’s important to keep in mind that bonding material and fillings cannot be whitened with bleach. If you have these restorations in your mouth, you should consider how your teeth will look if the natural parts become whiter and the bonding stays the same.
Whitening is safe because the chemicals used to attack the organic molecules do not materially affect the mineral structure of the tooth itself. There are many studies supporting the overall safety of whitening by bleaching, though it’s possible to experience some temporary side effects such as tooth sensitivity. Your dentist will take precautions to protect your root surfaces to minimize your potential for tooth sensitivity.
The bleaches used most often in teeth-whitening products are hydrogen peroxide and carbamide peroxide. The latter is particularly appropriate for home-whitening products because it is a more stable compound with a longer shelf life. It can also, safely be left on the teeth for a longer period of time, with less risk of sensitivity. Professional bleaching solutions containing hydrogen peroxide, a faster-acting bleach, can lighten teeth up to 10 shades in about an hour, though some people may need several treatments to achieve the desired level of whitening.
