Laser
Tooth Whitening by The laser teeth whitening
"Gentle, Safe, Fast and Effective in just 1 visit"
Aesthetic
expectations of patients have increased dramatically over the last few
years leading to an increased interest in various tooth whitening
procedures available on the market.
Although home bleaching is effective and has become extremely popular
over the past decade, it nevertheless presents drawbacks. Patient
complaints are often related to uneasy trays, gum and stomach
irritation, and unpleasant taste. Furthermore, the home bleaching
technique is a time consuming procedure. In some case the treatment
takes several weeks, and does not always show the desired results.
Another once popular technique involved hot bleaching with a heat lamp.
Among problems associated with this technique were increased tooth
sensitivity, pulpitis, etc.
Today's studies and research prove that laser energy (which is single
color light energy) provides the key to in-office tooth whitening. The
advent of the dental laser has proven to be the means of alleviating
some of the problems of in-office bleaching. Since the laser energy
potentially accelerates the chemical reaction, it thereby expedites the
process without raising the temperature of the teeth, thus avoiding
damage to the pulp.
Laser tooth whitening is safe and will not soften enamel or existing
fillings. The main ingredient in the gel that's used during the process
is hydrogen peroxide. Dentists have used hydrogen peroxide solutions to
whiten teeth for years. |
| The Chemical Reaction |
|
| Hydrogen
peroxide (H2O2) breaks down to water (H2O) and a free oxygen radical
(O) The smaller, less pigmented constituents by rapid oxidation. These
compounds have double bonds and long carbon chains that are
subsequently reduced to smaller carbon chains and hydroxyl groups,
which eliminate discoloration.
The
initiation of bleaching occurs through the application of laser which
emits monochromatic light at a specific wavelength absorbed by the
catalyst molecules only, thus accelerating the release of activated
bleaching molecules.
|
Hydrogen peroxide, the most accepted active ingredient for in-office
bleaching, does not decompose readily, which is partly why current
bleaching procedures require lengthy visits.
“Truly” Laser Tooth Whitening has developed a Laser Gel that, when
combined with hydrogen peroxide, becomes a solution responsive to
specific laser wavelengths resulting in a rapid production of free
oxygen radicals.

| Differentiate Between Laser and Non-Laser Tooth Whitening |
Laser |
| The
laser wavelength output is synchronized to the proprietary whitening
gel, which increases efficiency and minimizes the amount of energy
required to produce maximum whitening. This results in shortened
treatment time and increases effectiveness while eliminating the
heating of teeth that can result in post-operative sensitivity |
Non-Laser |
| Ordinary
non-laser whitening systems require longer treatment times and higher
energy output because of their inefficiencies. Non-laser whitening
devices use just a tiny percentage of the polychromatic light's energy.
The rest of the energy is wasted as heat and light, which is absorbed
by the teeth and adjacent tissues, which often results in
intra-operative and post-operative sensitivity. |
