There are many types of teeth whitening methods like in office bleaching, home bleaching, scaling & polishing, laser bleaching, whitening tooth pastes and gels etc.
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
In conventional bleaching techniques, the dentist will apply either a protective gel to your gums or a rubber shield to protect your gums. Bleaching agent is then applied to the teeth. A special light or laser might be used to enhance the action of the whitening agent. In home bleaching, peroxide-containing whiteners actually bleach the tooth enamel.
"Laser whitening is the best way to dramatically whiten your teeth in an hour."
A white bright smile can be a confidence booster and a great way to get noticed.
Laser whitening is the wave of the future (as is laser dentistry, in general). In just one appointment your teeth can lighten anywhere from 5-10 shades.
Lasers were introduced for teeth whitening in response to consumer complaints that traditional bleaching was too painful and resulted in inflammation & time consuming. Lasers, on the other hand, can be focused on a very specific area to avoid these effects & save time.
Laser teeth whitening simply refers to a professional teeth whitening treatment where hydrogen peroxide bleaching gel is applied to your teeth and a whitening accelerator light is directed at the teeth to help achieve maximum whitening results in under an hour.
WHAT CAUSES YELLOW TEETH?
There are numerous types of teeth stains; some are genetic, environmental or pharmacological in nature. The most common are surface stains on the enamel or beneath the enamel in the dentin. Surface stains are caused by foods, beverages and lifestyle behaviors, like smoking. Over time, surface stains may penetrate the enamel and change the color of the dentin, which darkens the overall appearance of the tooth due to the translucency of the enamel layer. When this occurs, the tooth often appears yellow.
WHAT TEETH WHITENING OPTIONS ARE THERE?
There are many whitening options, from OTC toothpastes, rinses and strips, to professionally supervised solutions such as Zoom in-office and take-home whitening & laser whitening etc.
Some people who use teeth whiteners may experience sensitivity. That happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and irritates the nerve of your tooth. In most cases the sensitivity is temporary. You can delay treatment, then try again.
Overuse of whiteners can also damage the tooth enamel or gums, so be sure to follow directions and talk to your dentist.
