TEETH WHITENING MOBILE

Brushing and flossing are everyday ways to keep your teeth bright, white and in good shape. Still, if you might think your smile is lacking some radiance or is more yellow than it used to be, you’re not alone. When the American Academy of Cosmetic Dentistry questioned people what they ‘d most like to improve about their smile, the most common response was whiter teeth. The American Association of Orthodontists also found that nearly 90% of patients asked for tooth whitening.

Contemplating teeth whitening? Get the facts first. Here are five of the most commonly asked questions about the process.

Why Did My Teeth Change Color?
Gradually, your teeth can go from white to not-so-bright for a variety of reasons:

Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that affix to the white, outer area of your tooth (enamel).

Tobacco Use
Two chemicals found in tobacco create uncooperative stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellow, surface-staining substance.

Age
Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin. With time, the outer enamel layer gets more delicate with brushing and more of the yellow dentin shows through.

Trauma
If you’ve been hit in the mouth, your tooth may alter color because it reacts to an injury by laying more dentin, which is a darker layer under the enamel.

Medications
Tooth darkening can be a reaction of certain antihistamines, antipsychotics and hypertension medications. Children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are developing (either in the womb or as a baby) may have discoloration of their adult teeth later in life. Chemotherapy and head and neck radiation can also darken teeth.
How Does Teeth Whitening Work?

Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less strong and your teeth more vibrant.

Does Whitening Work on All Teeth?
No, which is why it is necessary to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all kinds of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray colorations may not bleach whatsoever. Whitening will not work on caps, veneers, crowns or fillings. It also won’t be sufficient if your tooth discoloration is caused by medications or a tooth injury.

What Are My Whitening Options?
Speak with your dentist before beginning. If you are a candidate, there are four ways to put the sparkle back in your smile:

Stain Removal Toothpastes
All toothpastes help remove surface stain through the motion of mild abrasives that scrub the teeth. Look for whitening toothpastes that have earned the ADA Seal of Acceptance for stain removal (it will tell you on the package). These toothpastes have added polishing agents that are healthy for your teeth and provide stain removal success. Unlike bleaches, these varieties of ADA-Accepted products do not alter the color of teeth because they can only remove stains on the surface.

In-Office Bleaching
This procedure is called chairside bleaching and typically requires only one office visit. The dentist will apply either a protective gel to your gums or a rubber shield to protect your gums. Bleach is then applied to the teeth.

At-Home Bleaching from Your Dentist
Your dentist can possibly provide you with a personalized tray for at-home whitening. In this case, the dentist will give you guidelines on how to place the bleaching solution in the tray and for what period of time. This may be a preferred option if you feel more comfortable whitening in your own home at a slower pace, but still with the advice of a dentist. Out-of-office bleaching can take anywhere from a few days to a few weeks.

Non-prescription Bleaching Products
You may see different options online or in your local food store, such as toothpastes or strips that whiten by bleaching your teeth. The concentration of the bleaching agent in these products is less than what your dentist would use in the office. If you are considering using an over-the-counter bleaching kit, go over options with your dentist and search for one with the ADA Seal of Acceptance. That means it has been tested to be harmless and effective for teeth whitening. Get a list of all ADA-Accepted at-home bleaching products.

Are There Any Side Effects from Teeth Whitening?
Some people who use teeth whiteners may experience tooth sensitivity. That happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and disturbs the nerve of your tooth. In most cases the sensitivity is temporary. You can delay treatment, then try again.

Overuse of whiteners can also damage the tooth enamel or gums, so be sure to follow directions and speak to your dentist.
