The procedure of Laser Teeth Whitening
The bleaching compound usually contains a high concentration of peroxide (15-50%)
and so the dentist will usually place some form of protection around the gums so that only the teeth are exposed to the compound.
The whitening gel is then applied to the surface of the teeth and exposed to a light or laser for approximately 1 hour, which activates it
and speeds up the whole process making the whitening more effective.
The procedure is based on the use of peroxide gel that is applied to teeth, with the addition of a laser light which is used to activate
the bleaching agent and accelerate the peroxide’s reaction with tooth stains.
Advantages of Laser Teeth Whitening
A single one hour appointment is usually all that is needed for laser whitening to offer you a bright smile. The outcome is beautiful and the investment in time is minimal.
In just one appointment the teeth can lighten by 5-10 shades.
Laser whitening can whiten deeply stained teeth, removing even the more difficult stains below the tooth’s surface like those caused by tetracycline more effectively than any other whitening method.
Lasers can be focused on a very specific area targeting only the tooth surfaces and not the gums, avoiding gum irritation which is a common problem with other whitening methods.
Results of laser tooth whitening last for a minimum of two years, much more than other methods.
Disadvantages :
This is the most expensive whitening procedure.
The change will be very sudden so it will be obvious that you have received treatment.
How Laser Teeth Whitening works?
Bleaching is a procedure that is based on breaking the large light absorbing molecules in the tooth structures (that we see as stains),
into smaller molecules that do not absorb the light. This causes a greater level of reflection, and therefore teeth look whiter.
This reaction is started by the bleaching agent.
The hydrogen peroxide (H2O2) reacts with light and oxygen to form at first hydroxyl radicals (OH) and finally water (H2O) and free oxygen radical (O).
The free radicals produced by the reaction penetrate the tooth structure and break down stains into progressively smaller particles by rapid oxidation.
The conversion of hydrogen peroxide to free radicals can be accelerated by exposure to light of certain wavelengths,
basically from about 400 to 560 nanometers. That is the role of the laser in the whitening process.
Laser teeth whitening is the most modern bleaching method that can offer you the Hollywood smile you always dreamed of.
