The laser emits light
energy which is then absorbed by the blue pigment
of the bleaching gel. Bleaching occurs when
free oxygen radicals from the breakdown of
hydrogen peroxide chemically reduce larger
organic-pigmented molecules into less pigmented
constitutes through oxidation. Using the laser
accelerates the breakdown of hydrogen peroxide
thus accelerating the bleaching process.
How
fast is it?
The most obvious advantage of laser tooth whitening
is the speed at which the bleaching process occurs.
With home bleaching technique, it take a minimum
of two weeks or can take as long as two months before
results are achieved. Laser bleaching in comparison
only takes one hour before teeth are markedly whiter.
Is
there any sensitivity after treatment?
In addition to being time efficient, laser
whitening also avoid other complicatons associated
with the home bleaching and other in-office bleaching
(bleaching with heat lamp). Some patients suffer
from tooth sensivity after the home and in-office
bleaching. Their teeth can be sensitive to cold
substances and air. With laser whitening the
number of patients complaining of sensivity is
lowered because the treatment time is much shorter.
How
safe is it?
The existing in-office bleaching method used
to accelerate the bleaching process relies on
heat as the energy source. The heat has potential
to damage the soft tissue or pulp which consists
of the tooth's nerve and blood vessels. The tooth
is a vital tissue, so if the temperature goes
up more than five degrees the pulp will be damaged
and the tooth will be dead. So the pulp can be
damaged if the process of heat lamp application
is too long. Laser is the only available method
that accelerates bleaching and does not cause
damage to the pulp.
How
much whiter can it do?
This generally depends on patient's tooth nature
and original color. There are numerous causes
for tooth discoloration and staining, some more
preventable than others. Some people genetically
have yellow teeth, but there are many environmental
reasons for discoloration. The most common is
drinking dark-colored drinks like tea, coffee
and cola. People also suffer from fluorosis and
tetracycline stains. Fluorosis is the result
of having too much fluoride when your teeth are
developing. Tetracycline stains occur when the
tooth is developing and you take Tetracycline
antibiotics. As with any medical or cosmetic
procedure, therefore, the results of laser tooth
whitening cannot be predicted. Some patients
get more degrees of whiteness while some people
see only 1-2 shades whiter.
How
long will the whiteness last?
The long-term effects of the treatment are
also diffcult to predict and vary from one person
to another. The results can last for up to one
and a half years but obviously this is dependent
on your lifestyle. If, after treatment, patient
consumes much of dark-colored drinks, the results
will not last for long. However, you can come
for touch ups which will not takes as long as
the initial treatment.
Are
my teeth suitable for laser whitening?
It gives magical results for anyone who wants
to whiten their teeth. This includes people with
teeth which have been stained by smoking or by
substance like coffee or tea.
How
white could my teeth be?
The result will be white, shiny teeth.
How
long will the whitening last?
The effect last for two years.
How
long does treatment take?
In only 1 hour, discolouration which has built
up over the years will magically disappear.
