How Can I Brighten My Smile?
Your wedding is coming up, and you want your smile to be its brightest. Or maybe you have an important speaking engagement. Whatever the reason, tooth bleaching isn't just for movie stars, and it isn't just for one day. Many people have had their teeth bleached, and probably millions more are thinking about it. The desire for a brighter smile with whiter teeth is very strong, and tooth bleaching safely lightens the color of the teeth, lasting for up to five years. The most effective and safest method of tooth bleaching is dentist-supervised.
First, the dentist will determine whether you are a candidate for tooth bleaching and what type of bleaching system would provide the best results. If you're in a hurry for whiter teeth, you may decide to have your teeth lightened immediately. Your dentist will use either an in-office bleaching system or laser bleaching while you sit in the dental chair. Some patients choose dentist-supervised at-home bleaching, which is more economical and provides similar results.
How it Works and Safety?
Lightness should last from one to five years, depending on your personal habits such as smoking and drinking coffee and tea. At this point, you may choose to get a touch-up. The retreatment time is much shorter than the original treatment time.
The active ingredient in most of the whitening agents is carbamide peroxide; when water comes into contact with this white crystal, the release of hydrogen peroxide lightens the teeth.
