StainingWithinaToothRequiresaClinicalWhiteningApproach

Home whitening kits are a popular way to turn a dull smile into a dazzling one. But these self-applied products only work for teeth with outer enamel stains — if the discoloration originates inside a tooth, you’ll need professional treatment.

Known as “intrinsic staining,” this type of discoloration most often occurs within a tooth’s pulp or dentin layers. There are a number of causes like tooth trauma or tetracycline use at an early age. A root canal treatment used to remove infection from deep within a tooth can also cause discoloration: sometimes blood pigments left after tissue removal or the filling materials themselves can stain a tooth’s interior.

Intrinsic staining can often be treated by placing a bleaching agent, usually sodium perborate, into the tooth’s pulp chamber. But before undertaking this procedure on a tooth that’s undergone a root canal treatment, we want to first ensure the filling is intact and still adequately sealing the tooth from infection. We also want to make sure the supporting bone is also healthy.

If all’s well, we access the pulp in the same way as the root canal treatment, and preferably through the same access hole. We then clean out the pulp chamber of any stained matter and then ensure the root canals remain filled and sealed off from the pulp chamber.

We can then place the bleaching agent into the pulp, a process that will need to be repeated every three or four days to achieve the desired level of brightness. After each session we place a cotton pellet over the opening and held in place with a temporary adhesive; we can easily remove and re-apply this covering during subsequent sessions. Once we’ve achieved the desired color change, we seal the tooth with a permanent filling and restore the access cavity with a tooth-colored composite resin material bonded to the enamel and dentin.

There are other options for an intrinsically stained tooth like veneers or crowns that outwardly cover the discoloration. Internal bleaching, however, is a more conservative approach that causes less alteration of the tooth. If successful, it can restore a stained tooth to a brighter, more attractive shade.

4ReasonsWhyaHomeWhiteningKitMightnotbeRightforYou

Do-it-yourself (DIY) whitening kits are a popular option for restoring a healthy shine to stained and dulled teeth. They're relatively safe and generally live up to their packaging claims.

But a home kit might not always be your best option. Here are 4 reasons why DIY whitening might not be right for you.

You're on the early side of your teen years. Tooth whitening at home is quite popular with teenagers. For older teens it doesn't really pose a dental risk as long as you use the product appropriately (more on that in a moment). However, the immature enamel of younger teens' permanent teeth is still developing and can be vulnerable to damage by whitening processes.

You don't follow instructions well. Not to say you have this particular character quirk — but if you do you may run into trouble with DIY whitening. Home kits are safe if you follow their instructions carefully. If you use them to excess as one 13-year old boy was reported to have done, you could severely (and permanently) erode your teeth's protective enamel.

Your teeth are in need of dental work. Tooth whitening can't fix everything that may be contributing to an unattractive smile. It's always better to have issues like dental disease or chipped teeth addressed first before whitening. And, if your tooth discoloration originates from inside your tooth, a whitening kit won't help — they're only designed for staining on the enamel's outside surface. You'll need a special dental procedure to whiten internal (or intrinsic) tooth staining.

You want to control the amount of brightness. Home kits don't have the level of fine-tuning that a clinical procedure can achieve. While the bleaching agent in a professional whitening solution is much stronger than a home kit, your dentist is trained in techniques that can vary the amount of bleaching, from a softer white to dazzling “Hollywood” bright. And clinical whitening usually takes fewer sessions and may last longer than a home kit.

If you're interested in teeth whitening, see your dentist for a dental examination first before purchasing a DIY kit. Even if you decide to do it yourself, your dentist can give you buying advice for whitening kits, as well as how-to tips.

KathyBatesPlaysItSmartWithProfessionalTeethWhitening

Academy Award-winning actress Kathy Bates knows how important it is to present your best face to the world — and one of the most important features of that face is a beaming smile. But there came a point when she noticed something was a little off. “I've always had good teeth, but it seemed to me as I was getting older that they weren't looking as good,” Kathy explained in a recent interview with Dear Doctor magazine.

That's when she decided it was time to take action. Kathy had orthodontic treatment when she was in her fifties, and she keeps her smile bright with tooth whitening treatments. She uses a kit provided by her dentist with a safe, effective whitening solution.

Of course, a bright, healthy smile looks great anywhere — whether you're on the red carpet or “off the grid.” And you don't have to be a Hollywood star to have professional whitening treatments. In fact, teeth whitening is one of the most popular and affordable cosmetic treatments modern dentistry offers.

The basic options for professional teeth whitening include in-office bleaching or take-home kits. Both types of dentist-supervised treatments offer a safe and effective means of getting a brighter smile; the main difference is how long they take to produce results. A single one-hour treatment in the office can make your teeth up to ten shades lighter — a big difference! To get that same lightening with at-home trays, it would take several days. On the plus side, the take-home kit is less expensive, and can achieve the same results in a bit more time.

It's important to note that not all teeth can be whitened with these treatments. Some teeth have intrinsic (internal) stains that aren't affected by external agents like bleaches. Also, teeth that have been restored (with bonding or veneers, for example) generally won't change color. And you can't necessarily whiten your teeth to any degree: Every tooth has a maximum whiteness, and adding more bleach won't lighten it beyond that level. Most people, however, find that teeth whitening treatments produce noticeable and pleasing results.

What about those off-the-shelf kits or in-the-mall kiosks? They might work… or they might not. But one thing's for sure: Without a dentist's supervision, you're on your own. That's the main reason why you should go with a pro if you're considering teeth whitening. We not only ensure that your treatment is safe — we can also give you a realistic idea of what results to expect, and we will make sure that other dental problems aren't keeping you from having a great-looking smile.

How often does Kathy Bates see her dentist for a checkup and cleaning? “I go about every four months,” she noted. “I'm pretty careful about it.” And if you've seen her smile, you can tell that it pays off.

SpruceUpYourSmileWithTeethWhitening

Clothing and hair styles may come and go, but a dazzling smile is always in fashion! If you're considering options for perking up your appearance, brightening your pearly whites is a quick and affordable way to achieve eye-catching results.

You have several choices when it comes to teeth whitening. But to get the safest, most appropriate, and most satisfying results, you should start with a proper dental examination. A professional assessment of your oral health can determine the cause of your tooth discoloration and may reveal the need for a particular treatment before, or in addition to brightening the color of your teeth.

Brightening Options

When we talk about teeth whitening, we generally are referring to “bleaching,” which actually returns your teeth to their natural tooth color. A thorough cleaning — generally part of a routine checkup — often can remove surface discoloration/staining (such as coffee, tea, tobacco or red wine).

There are basically three approaches for external bleaching/whitening of your teeth. They vary based on the strength of the bleaching solution, method of application, duration of treatment, and cost considerations.

Professional In-Office Whitening. This approach involves the carefully controlled application by a dental professional of a powerful and fast-acting concentration of hydrogen peroxide gel. Professional whitening can achieve the most significant color change in the shortest amount of time, but it is pricier than the other options.

Professionally Dispensed Take-Home Whitening Kits. These include a lower-strength peroxide gel applied via flexible plastic bleaching trays custom made by our office specifically for your teeth. The tailored fit of the trays helps ensure an even and thorough coating. A more affordable option than the in-office procedure, it also requires more time to achieve similar results.

Over-the-Counter Products. These feature the lowest-concentration bleaching gel, which is applied to the teeth using one-size-fits-all trays or strips, or a paint-on applicator. While they are the least expensive option, they take the longest to achieve maximum results and may not reach all teeth.

ToothBleachingTestYourKnowledge

Dental professionals sometimes use specialized words, and you may not be clear about exactly what we mean. Test yourself on some of the specialized vocabulary concerning tooth whitening. How many of the following can you define correctly?

1. Bleaching?
A method of making yellow, discolored teeth whiter. It is relatively inexpensive and safe, with few side effects.

2. External or extrinsic staining and whitening?
Extrinsic staining mainly results from diet and smoking. For example, foods such as red wine, coffee and tea can produce extrinsic stain. Teeth with these stains are bleached by placing whitening substance in direct contact with the living tooth surface.

3. Internal or intrinsic staining and whitening?
Intrinsic tooth discoloration is caused by changes in the structure of enamel, dentin, or pulp tissue deep within the root of the tooth. When the discoloration originates with the pulp tissue, root canal treatment may be needed to whiten the tooth from the inside.

4. Chromogenic material?
Color generating material that may get incorporated into the tooth's substance. It can be a result of wear and aging, or can be caused by inflammation within the tooth's pulp.

5. Carbamide Peroxide?
A bleaching agent discovered in the 1960s and frequently used for tooth whitening. When used, carbamide peroxide breaks into its component parts, hydrogen peroxide and urea, which bleach the colored organic molecules that have been incorporated between the crystals of the tooth's enamel.

6. Power Bleaching?
This technique is used for severely stained tooth. It uses a highly concentrated peroxide (35 to 45 percent) solution placed directly on the teeth, often activated by a heat or light source. This must be done in our office.

7. Tetracycline?
An antibiotic used to fight bacterial infections. It can result in tooth staining when taken by children whose teeth are still developing.

8. Rubber Dam?
Use of strong bleaching solutions requires protection for the gums and other sensitive tissues in your mouth. This is done using a rubber dam, a barrier to prevent the material from reaching your gums and the skin inside your mouth. Silicone and protective gels may also be used.

9. Whitening Strips?
Strips resembling band-aids that you can use in your home to whiten your teeth. They generally contain a solution of 10 percent or less carbamide peroxide gel. When using them, be sure to read the directions and follow them strictly to avoid injury or irritation.

10. Fade Rate?
The effects of bleaching may fade over time, from six months to two years. This is called the fade rate. It can be slowed down by avoiding habits such as smoking, along with food or drink that causes tooth staining.
