Laser Tooth Whitening by LaserSmile™
"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. LasersmileTM 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

Etiology Type of Discoloration

Stains Mild Tetracycline stains
Discoloration Caused by tobacco, coffee, tea or highly colored food
Yellowing Natural aging


Factors & Causes

Tooth color is in most cases an inherited trait, however, tooth color mainly depends upon the condition of the teeth, dental health and lifestyle.

Various factors could lead to tooth darkening or discoloration. The most common factor are : the intake of staining fluids, such as cola, tea, coffee or wine; tobacco; cigarette smoking and time.

Change in temperature of foods and drinks allow the teeth to expand and contract, thus enabling the penetration of stains onto the teeth.

Foods that are slightly acidic open up the pores of the enamel and allow stains to move in. Teeth darken as we age because the staining factors act upon the teeth for a longer period of time.

There are also internal causes such as tetracycline stains, fluorosis, injury, dental work and, of course, the aging process. Depending upon the severity of staining, bleaching will lighten the darkest areas but may not totally remedy the condition.
