Teeth whitening methods may
provide a prolonged effect and
showy smile. The efficiency depends on rightly chosen method for this
or that case. There are basic
techniques
that are used at hospitals and at home. Among them, they mark out two
main tooth whitening methods:
*application of a high concentration of oxidising agent for a short
period of time during tooth whitening that is called office
bleach. It gives quick
results but there are certain
risks
of chemical burning of the soft tissues. That is why, during the most
in-office bleaching operations, one uses a light-cured protective layer
that is cautiously laid on the gums and papilla. The bleaching agent
may be carbamide peroxide, which changes into hydrogen peroxide in the
mouth, or hydrogen peroxide itself. The bleaching gel usually contains
up to 35 per cent hydrogen peroxide equivalent.
*usage of a thin mouthpiece or strip to keep a low concentration of
oxidising agent next to the teeth for several hours each day from five
to fourteen days. It is so-called take-home or
over-the-counter bleaching or
teeth
whitening. This procedure requires more time to receive a
desirable effect, but it involves less risk than the first method. The
bleaching agent is typically up to 10 per cent hydrogen peroxide
equivalent.
It is important not to forget that people react to this or that
chemicals or medication differently; for avoiding unnecessary
consequences during or after tooth whitening, one should find out all
possible allergies that he/she
has.
Nevertheless, not all tooth whitening methods are so involved and
sophisticated. A person may have white and health teeth buying and
using
tooth
whitening products that are often offered in retail stores.
High-end and professional toothpastes are the means for both cleaning
and whitening. Simple brushing (in the morning and in the evening
daily) helps prevent going to a dentist for a long period of
time.
