- There are several methods of teeth whitening that
vary in price and in how well they work:
o Chairside bleaching or “power bleaching.”
In your dentist’s office, he or she applies a gel or rubber shield
to protect your gums and oral tissues, and then puts a bleach on your
teeth. Ask if the bleaching agents
have the ADA* Seal. A special light or a laser may be used to help
the bleach work better, but no products that use lasers are accepted right
now by the ADA. With this method you may have to go for more than one
visit. You will see results right away (about 5 shades brighter). It works
well on a range of stains.
o Professional dispensed bleaching solutions.
These products are for use at home, and you get them from your dentist.
They contain peroxide(s), which actually bleach the tooth enamel. Most
come in a gel and are placed in a mouth guard or tray that fits inside
your mouth around your teeth. How long you use them depends on what
results you’re looking for and if you are sensitive to the bleach. Some
products are used for about twice a day for two weeks, and others are used
overnight for one to two weeks. They help many types of staining. Your
teeth turn about six shades brighter with long-lasting results.
o Over-the-counter, TV, and Internet products.
These products are for use at home and include whitening
strips, paint-on products, and gels and trays. They have a low amount
of peroxide. You wear some during the day and apply some at night before
bedtime. They have limited results without first having professional
removal of the stains. But they can help prolong the results you get from
professional removal. They can help staining due to age and certain foods.
Your teeth turn about two shades brighter for up to six months. None of
these gels and trays are accepted by the ADA.
o Whitening toothpastes. All
toothpastes help remove surface stain through the action of mild
abrasives. "Whitening" toothpastes that have the ADA seal have special
polishing agents that remove even more stains. Unlike bleaches, these
products do not change the actual color of teeth. They help slight surface
stains only. You might see temporary results with claims of one to two
shades brighter.
Before you use any whitening products, talk with your dentist first. He or
she can help you decide which method is best for the type of stains that
are on your teeth. Not all products will work on all people.Keep in mind
that whitening your teeth alone does not make your mouth any healthier.
