Tooth Whitening Information for Patients
What is tooth whitening?
Teeth can often be whitened by the several new techniques of "bleaching" available
today. The most common method used is the "in-office" method where
a strong bleaching agent is placed over the isolated teeth and a special light
is used to assist the bleaching material lighten the teeth. This method is
generally more controlled and probably better for people who have tetracycline
stains or streaks on their teeth. The "home" techniques involve
making trays which fit into the mouth and these are then filled with
bleaching materials. When worn for a few hours a day, noticeable results
are seen generally within a few days to a couple weeks. Results vary
from individual to individual and it is probably best to check with
your dentist to help decide which method works best for you. Some of
the factors involved include the intensity of the stains, whether or
not you have fillings or crowns on your front teeth as well as what
may have caused the stains.
What causes staining of teeth?
The most common include aging, consumption of staining substances (coffee,
tea, colas, tobacco, blueberries etc.), and old fillings in the teeth. During
tooth formation , consumption of the antibiotic tetracycline or excessive
fluoride may also cause tooth discoloration.
Who may benefit from tooth whitening?
Almost everyone with healthy teeth will benefit. There is virtually
no downside to whitening and lots of upside. As long as you do not have
any fillings or crowns on front teeth, you will benefit from tooth whitening
by having a whiter younger smile.
Is the process safe?
Whitening is gentle and safe when supervised by your dentist. In fact, dentist-supervised
whitening has been done for nearly a century, but has increased in popularity
in recent years as yellowed teeth are becoming less and less acceptable,
both socially and professionally. Procedures have been simplified and shown
to be safe. Reports that claim that the bleaching gel will destroy your enamel
are not true. The bleaching process causes no long term harmful effects to
your teeth or gums.
How long does it take?
With in-office bleaching the results are instantaneous but for maximum whitening,
two sessions are required. With tray bleaching most people will notice a
change in the color of their teeth the first night they bleach. Tray bleaching
takes about 7-10 days to complete. For the fastest and longest lasting results,
we recommend a combination of in-office and home whitening.
Are there any side effects?
Some people may experience a transient sensitivity to cold while bleaching.
This disappears soon after the treatment is finished. However you can decrease
the frequency of wearing the trays to cut down or eliminate the symptoms.
Your dentist may also choose to prescribe a fluoride gel that you wear
in the trays for extreme sensitivity. It is important to note that all
symptoms are temporary while you are bleaching. There are no long term
harmful effects to bleaching
How long do the results last?
Teeth will stay bleached permanently. However depending on your habits,
you may need a touch up treatment once every 6 months. If you smoke,
drink tea, coffee, or red wine, your teeth will stain faster therefore
requiring more frequent touch ups.
You can help your teeth remain white by brushing twice a day, cleaning
between the teeth daily with floss or interdental cleaners, seeing your
dentist for regular professional cleanings along with occasional touch-up
treatments.
What are the different methods available for whitening teeth?
The two main methods for bleaching are In-office
bleaching and a tray
system.
- With in-office bleaching, a special light is
used to heat the bleaching gel to start the whitening process. The
light can be either a laser or a plasma arc curing light. The basic
idea is to heat the bleach to make the whitening reaction go faster.
- With tray bleaching, custom fitting trays are
made for your teeth in which a bleaching gel is worn for a period
of 7 to 10 days. Although slower, the results achieved are usually
superior than in office treatment. We usually do a combination of
in-office and tray bleaching for the best results.
Bleaching
Bleaching is a safe and effective way to whiten
and improve your smile. Our staff at downtown dental has a vast amount of experience
with most of the tooth whitening systems currently available including
the laser. We do a large number of whitening cases each month
and find that we have the most dramatic results with a system we
refer to as Deep Bleaching™.
The Procedure
There is no shortcut to getting guaranteed white teeth! Deep Bleaching™ is
a combination of in office bleaching and take home trays. Your first appointment
is a conditioning appointment that is done in the office for 30 minutes, followed
by two weeks with the take home trays and then a 1hr final in office boost procedure.
The combination bleaching process not only provides the whitest smile possible
for you but allows you to maintain your whiteness through the use of the trays. However,
if your desire is to only slightly whiten your teeth we usually suggest just
doing the Take-Home Trays. We no longer offer the 1hr in-office laser
bleaching procedure as the results are too unpredictable to justify the cost
and your time.
Side Effects
Deep Bleaching™ is the most advanced formulation for safe effective
teeth whitening. The
product we use generates free calcium ions to help re-mineralize your teeth during
the whitening process. It contains water so there is minimal sensitivity. However,
some sensitivity can be experienced for the first 24 hours after the procedure,
helped by Advil or Motrin.
How did my teeth get so yellow?
Over the years, like almost everyone, you've experienced a natural buildup
of organic pigments on your teeth. Colorized proteins from coffee, tea, and
other foods have simply darkened the natural whiteness of your teeth. The
use of tobacco, antibiotics, and certain minerals usually speeds the darkening
process. But, yellowing can be easily reversed.
What's the difference between dentist-supervised and over-the
counter treatments?
There are many differences, starting with the fact that your teeth and your
own dental situation are absolutely unique. Which is why the safety of your
treatment requires a dentist's evaluation and supervision. You'll also find
that custom trays designed by the dentist will fit better and will consequently
expel far less bleaching gel than the unsupervised, over-the-counter, one-size-fits-all
treatment alternatives.
What about those over the counter products?
The "boil-and-bite" trays used by the over-the-counter
products overlap soft tissue producing more irritation. They also feel
bulky in your mouth. This results in discomfort and possible TMJ problems.
- A dentist-designed tray is less bulky.
- It conforms more closely to the natural contours of the teeth,
is far more comfortable, and assures a superior result.
- You'll find a significant difference in both the comfort and safety
of dentist-designed trays vs. unsupervised over-the-counter, one-size-fits-all, "boil & bite" trays.
Who can use tooth whitening?
Nearly anyone ages nine to 90. If you want to obtain a more confident smile
by improving the whiteness of your teeth, talk to us.
How does whitening work?
Your dentist will first check your teeth and gums to be sure that you begin
the treatment in good dental health. Then your dentist will take an impression
of your teeth in order to provide you with a custom fit plastic tray designed
to hold the bleaching gel next to your teeth. Following the bleaching program
your dentist suggests, you'll notice the results quickly, as the gentle oxygenating
action of the gel begins to whiten your teeth. Your dentist may choose to
begin with a short in-office bleaching session.
Is there any discomfort?
There is little, if any. Some patients might feel an increased sensitivity
to cold, heat, or pressure during the whitening process, but this sensitivity
ends a day or two after the treatment is completed. Any note of persistent
discomfort should be reported to your dentist.
Will the whitening damage my teeth?
Not at all. The whitening process will not affect your enamel, tooth structure,
bonding or restorations. Whitening acts only on the molecules that carry
the discoloration.
How long will it last?
Non-smokers who don't drink coffee or tea often see little or no
change over five years. But your own long-term results will depend
on your habits and the specific foods you eat. Based on those variables,
some patients may require a "touch-up" treatment at regular
intervals.
General Tips
For sensitive teeth avoid foods with citric acid. If sensitivity persists:
- Have patient call office immediately.
- Prescribe fluoride for alternate nights.
- Purple tray after bleaching session indicates presence of zinc in
fillings.
- Keep bleach refrigerated (store standard bottles upside-down).
- Do not smoke, eat or drink with tray in place.
- Pregnant women should only bleach with the agreement of their physicians.
- Bleach upper arch first.
- Wait two weeks before doing crowns or fillings.
Key Benefits of bleaching
Corrects browns, yellow and mottle tooth staining
- Works on people of any age.
- Is a near permanent solution for a "dull" smile, restoring
brightness and brings a smile alive.
