Some of the larger
oral care companies have developed a teeth whitening
process that involves brushing on a solution that
theoretically whitens teeth. This page explores
how it works, how to do it, and if it's effective.
Description
Basically, the user brushes a solution containing
some form of peroxide (usually carbamide) onto their
teeth and then leaves it there for a certain amount of
time. After several days or weeks, teeth are
supposed to appear whiter.
How it works
Like all products that bleach teeth with a form of
peroxide, brush on teeth whitening works by bleaching
stains present in teeth. As carbamide peroxide is
broken down in the mouth, oxygen works upon the stained
organic deposits which "oxidizes" them into a whiter
color.
Effectiveness
Brush on teeth whitening is generally not as
effective as some other methods such as at home kits.
But it has worked for some people who want minimal
lightening. Thus, if you're just looking to
lighten your teeth a bit or maintain the effects of a
previous whitening, brush on products can work.
Advantages/Disadvantages
The advantages of brush on teeth whitening products
are their relative ease of use and low cost.
Although some people have reported issues with using
these products, most people find them relatively
convenient.
The disadvantages of these products are their
unpleasant taste and the difficulty keeping the solution
on the teeth long enough for it to work. This is
why these products are only capable of whitening maybe
one or two shades.
General Instructions
You should always follow the instructions provided
with whatever brush on whitening product you purchased.
Generally, this is the three step process for using
these products:
- Brush teeth
- Dry surface of teeth
- Brush thin layer of solution onto teeth
That's basically it. Some companies want you to
use this overnight, others want you to rinse off.
Be sure to check the instructions provided with the
product.
Summary
Brush on teeth whitening products are somewhat
effective if you're looking to whiten your teeth just
one to two shades or to maintain previous whitening
results. They are fairly easy to use (no trays)
and are relatively inexpensive. But they will not
dramatically lighten your teeth like at
home kits,
custom kits, or a
dental visit.
