Store-bought products
People, sometimes, initially turn to over-the-counter products for teeth
whitening. These come in toothpaste products and whitening strips. Some
mouthwashes contain whitening agents. People can find these products at the
local supermarket or drug store.
Results from using these products can vary. However, generally, it will take
longer to whiten teeth when using toothpaste, whitening strips, and other
options. The teeth likely will not improve by more than a few shades, as there
is a low concentration of hydrogen peroxide in these products. People will have
to use these products longer and more often to maintain white teeth.
Take-home trays
Another method of using at-home teeth whitening first starts in the
dentist’s office. When a patient is concerned about tooth discoloration, a
visit to the dentist is a good step. The dentist will examine the patient and
make impressions of the teeth. From these, the dentist can custom-make a
mouthguard-like appliance that the patient will wear overnight.
With whitening trays, the dentist will instruct the patient to put a certain
amount of hydrogen peroxide solution in the mouthguard before putting in the
trays. Usually, the patient will wear the trays for several weeks or a few
months. Some people see results within a few days. There is more hydrogen
peroxide in this solution than there is with store-purchased products. Once the
patient has used all of the whitening gel, the dentist can evaluate whether the
individual needs more or whether there is no need to continue the treatment.
In-office treatment
For the most serious discoloration issues, an in-office professional teeth
whitening might make the most sense. Instead of having to use a product daily
for weeks or months, the patient will only need to come into the dentist’s
office once or twice for about an hourlong appointment. Whitening treatments in
the office typically produce longer-lasting whiteness. The dentist can also
improve the person’s tooth color by several shades.
The procedure is pain-free. The patient will sit or lie in a dental chair while
wearing an apparatus in the mouth. A highly concentrated hydrogen peroxide gel
goes in the appliance. Then, the dentist will use heat or light to activate the
gel. The peroxide then penetrates deep into the tooth, breaking down the stains
and making the teeth whiter.
