At Home Teeth Whitening Trays Versus Professional Bleaching
By Jack Harmon
Have you ever consider why teeth get dark?
Tooth discoloration is not devastating in most cases especially today with advancements in tray based teeth whitening.
There are several key reasons why your teeth may get stained. The most obvious reasons include, heredity, tea, coffee, and colan, too much fluoride, and aging.
With advancement in whitening toothpastes this can lighten your teeth, but it is not a substitute for bleaching which will solve more intrinsic staining.
So how are tray-based teeth whitening technique given to the patient?
1. The teeth whitening gel is poured in the gel tray that just fits over your teeth.
2. The Carbamide Peroxide whitening gels ingredient enter the enamel to bleach the discolored areas.
3. During the whitening process the actual structure of each tooth is not actually harmed or transformed. But be aware that bleaching will not lighten crowns, fillings, and bonding.
Most teeth whitening systems can be broken into two general areas:
1. Professional whitening systems – These are performed in a dental office by a certified dentists using Carbamide Peroxide whitening gels and lasers to activate the solution.
2. At Home teeth whitening – Normally at home teeth whitening can be done with a tray based teeth whitening system in the comfort of your own home. Some system may require a quick appointment at the dentist to explain the instruction and mold a mouth piece. But it is very minimal.
With modern day advancements most dentists agree that tray bleaching or whitening is safe, and provides a very flexible way to lighten teeth two to four shades lighter.
How is tray based whitening different from professional whitening systems?
The popular professional whitening systems include the following:
1. BriteSmile (gas plasma light/light emitting diode)
2. LaserSmile (a Biolase laser)
3. LumaArch (halogen light)
4. Rembrandt Sapphire (plasma arc light)
5. Zoom! (metal halide light)
Laser treatment is much more aggressive then most tray based whitening systems. It is done by applying a 35% hydrogen peroxide gel-based solution versus a 15% on most tray based methods.
After applying the gel solution on the surface of the teeth, professional laser whitening light is held just inches away from the patient’s mouth to activate the peroxide.
Because professional whitening is done with a higher percentage of hydrogen peroxide gel and laser, it normally bleaches teeth faster.
But in the long run there is no evidence that the overall professional bleaching method will keep your smile whiter.
