Generally, bleaching
is successful in at least 90 percent of patients. Consider tooth
bleaching if your teeth are darkened from age, coffee, tea, or smoking.
Teeth darkened with the color of yellow, brown or orange respond better
to lightening. Other types of gray stains caused by fluorosis, or
tetracycline are lightened, but results are not as dramatic. If you have
very sensitive teeth, periodontal disease, or teeth with worn enamel,
your may not be a good candidate. Also note that bleaching will not
change the color of existing white fillings or crowns. After bleaching,
these may need to be replaced to match the new color of your teeth.
We offer two bleaching methods, dentist-supervised at home bleaching and
in office power bleaching. With at home bleaching, on the first
appointment, an easy and totally painless impression is taken of the
teeth to be lightened. After you leave the office, a special plaster is
poured into the impression creating a plaster model of your front teeth.
A thin clear tray is made to exactly fit over the model, with a special
space or reservoir where the bleach will go.
Over the counter, non-dentist supervised kits are available at the drug
store or on TV, but they lack the ability to make this special custom
tray. They use a home made "boil and bite" tray that lack the special
reservoir.
On your second visit, you will be shown how to apply the bleach into the
reservoir and how to wear the tray. The bleach is a specially buffered
gel containing carbamide peroxide (CH4N202)
and a special ingredient to reduce sensitivity.
Power Bleaching is performed in the office using a strong hydrogen
peroxide gel. The gums are first protected with a special film, the
teeth are isolated, and a 40% hydrogen peroxide gel is painted on. The
gel is activated using a special strong light and allowed to work for 20
to 30 minutes. Generally, several sessions are required. Extremely dark
teeth sometimes respond best to a combination of power bleaching and
supervised at home bleaching.
Bleaching can last for about one to five years depending your personal
habits such as smoking and drinking coffee and tea. When the teeth start
to darken, normally wearing your at home bleaching tray for one night . |
