Pearly white teeth!!!?
Nowadays we expect things quick, whether it's fast food, 1-hour dry cleaning or a quick lube. The latest entry in the speedy sweepstakes is teeth whitening--also known as "teeth bleaching"--with a handful of companies offering to turn teeth from yellow to light ivory in about an hour.





More and more people are seeking a pearly white smile. According to the American Academy of Cosmetic Dentistry in Madison, Wis., the number of teeth-whitening procedures being performed annually has increased by more than 300 percent since 1999.





Dentists began teeth bleaching 30 years ago when they discovered hydrogen peroxide and its cousin carbamide peroxide (used to aid gum healing after dental surgery) whitened teeth when the solutions came in contact with tooth enamel.





"It was so strong that if it touched the lips or the gums it would actually injure a person," says Dr. Michael Malone, President of the American Academy of Cosmetic Dentistry. Malone says that while it worked, dentists didn't have a reliable way to put it on teeth and keep it there long enough for it to be effective.





Peroxide is a strong oxidizing agent (it forms chemical compounds when it comes in contact with staining agents and decolorizes them). The peroxides used for teeth whitening are about 35 percent peroxide. By comparison, the over-the-counter type used to clean skin wounds is about 2 percent hydrogen peroxide.





In today's procedure, light is used to break down peroxide bleaching gels into oxygen molecules. The molecules penetrate the tiny pores of the enamel and dentin, and break up the stains that block out the light. As the stains are broken into smaller and smaller pieces, more light passes through the enamel, making it appear lighter.





Depending on the bleaching gel used and the length of time it is worn, initial results can be seen within an hour, or it can take three to four days. Complete results can be achieved in as little as a week or over the course of several months, depending on the source of the stain and the ability of the tooth to absorb the bleach. The whitening result may last for up to three years--longer in some cases, depending on smoking or drinking habits. To brighten the color back up, a simple process of bleaching for one or two nights with a single syringe of peroxide is usually sufficient.





The major change made over the last 30 years has been in reformulating the bleaching agents so they are more effective and easier to control. To protect against injury to gums and surrounding tissue, most systems isolate teeth with rubber dental dams.





Today's systems use "curing lights" that break down the peroxide gel, causing it to release millions of particles of oxygen and speed up the whitening process.





While there are four main competitors in the 1-hour whitening sweepstakes, Dr. Mark P. Goodman, in New Milford, N.J., says they all operate on the same basic principle. "Some probably work a hair better than the others but they're all very similar," says Goodman. The 1-hour treatments cost about $500 to $600.





Goodman says calling it a 1-hour treatment is a bit of an exaggeration. "Usually you're here about 2 hours before the whole thing is over."





Here are the four best-known quick "chair side" treatments.





A Perfect Smile





For more than a decade, the American Dental Association (ADA) Council on Scientific Affairs has monitored the development of oral hygiene products and dental procedures that boast teeth-whitening properties. As the demand for these products grew, the ADA saw a need for uniform definitions of whiteners.





To this end, the ADA defines "whitening" as any process that causes teeth to appear whiter. For the most part, this can be achieved in two ways. A product can bleach the tooth, which means that it changes the natural tooth color. Bleaching products contain a form of peroxide that helps remove deep or intrinsic, and surface or extrinsic, stains. Nonbleaching whitening products contain agents that use physical or chemical action to help remove surface stains only.





Unfortunately, there is no standard to judge the number of "shades whiter." When manufacturers make this claim, find out the criteria they use, when the measurements are taken, how the "shade" is measured, whether the shade is derived from a controlled scientific study or if subjective criteria are used. "Shades whiter" is more a marketing tool than a scientific measurement.


MAGIC MIRROR REVEALS WHO'S THE FAIREST


The BriteSmile (Walnut Creek, Calif.) whitening procedure consists of a lamp that filters light in the blue-green region of the spectrum (approximately 400 to 500 nanometers) and a delivery device that illuminates all of the patient's "smile teeth" at once. The light is used in combination with a 15 percent hydrogen peroxide gel buffered at a neutral pH that is compatible with tooth enamel. The gel contains other ingredients such as glycerin and highly purified water to prevent tooth dehydration and to further ensure dental safety. Also included is a light-activated agent to assist in stain elimination.





BriteSmile also uses a device dubbed the Magic Mirror. The patient can smile into the mirror and, with the click of a button, preview the final result prior to the BriteSmile treatment.





WHITENS TOPS AND BOTTOMS AT THE SAME TIME


The LumaCool Whitening System (LumaLite, Spring Valley, Calif.)--a follow-on system to the company's LumaArch--uses light-emitting diodes (LEDs) to activate a bleaching gel with virtually no heat.





The system whitens both arches simultaneously. LumaCool has an optical sensor that turns the device on and off, a countdown display window and remote-control operation. To avoid overexposure, an audible signal indicates when the whitening cycle is complete.





NO PAIN, GREAT GAIN


Featured on the TV show "Queer Eye For The Straight Guy," the Rembrandt Virtuoso System (Rembrandt/Den-Mat, Santa Maria, Calif.) is used by more than 7000 dentists nationwide. It uses Rembrandt Lightning Plus Bleaching Gel with the Rembrandt Sapphire Light as a curing light.





According to company officials, this product has been clinically proved to whiten teeth by as many as 10 shades after one treatment. The procedure can either bleach all teeth at once or one tooth at a time, allowing the dentist to concentrate on problem areas. The power light does not emit ultra-violet rays, so patients don't need sunscreen or sunglasses. Also, the bleaching gel contains a desensitizing agent that helps eliminate the sensitivity people often experience during a professional tooth-bleaching procedure.





NO TRAY TO WEAR


Discus Dental's (Culver City, Calif.) Zoom! system uses the FLASHlite 1001 LED curing light, which is powered by a lithium-ion battery. This pocket-size unit delivers fast curing of chemicals containing the photo-initiator camphorquinone (CQ) at the 468- to 470-nanometer range. A digital radiometer is built into the instrument's charger base to ensure that sufficient light has been applied.





The FLASHlite 1001 requires that all soft tissue in and around the mouth be protected. The clinician is required to monitor the procedure to ensure that any exposed skin or tissue is isolated. The patient must use protective eyewear during the procedure.





WORDS OF WARNING


The most commonly observed side effects to hydrogen and carbamide peroxides are tooth sensitivity and occasional irritation of the soft tissues in the mouth (oral mucosa), particularly the gums.





Before you dash off to the teeth-whitening kiosk at your local mall, you should undergo a professional cleaning by your dentist first. Prospective patients must understand that old restorations, crowns and fillings will not whiten. If the adjacent natural teeth whiten and the fillings and crowns do not match in color, the old restorations may need to be replaced. This will obviously add to the cost of the procedure and become more than a simple whitening.
Reply:You cant, just make them clean.
Reply:I'm sorry to say that you can't have pearly white teeth in just 3 days, all you need to have is clean teeth, don't worry about it. Teeth being clean is more important then it being white.
Reply:Your dentist is most concerned that you brush and floss twice a day. It doesn't matter that your teeth aren't white.
Reply:ring the dentist on monday and ask them if they do in-house whitting if they do you you are lookin at £600+ less if you are luck, we can do this at my dentist where i work, but it can only be done if the dentist is free as the treatment will take over 1 hour. and you will have to go back. if you don't get the help thaat you need then you can always email me.
