DeterminingtheRightWhiteningApproachisKeytoBrighteningaDullSmile

Bright, naturally white teeth are a key component in a beautiful smile. But the opposite is also true: nothing diminishes an otherwise attractive smile more than stained or discolored teeth.

There is good news, however, about tooth staining: it can be greatly reduced with the right whitening technique. But before taking action we need to first uncover the cause for the staining — whether from the outside or inside of the tooth, or a combination of both.

If it’s an external cause — known as extrinsic staining — our diet is usually the source. Foods and beverages that contain tannins, like red wine, coffee or tea fall in this category, as do foods with pigments called carotenes as found in carrots and oranges. Besides limiting consumption of stain-causing foods and maintaining daily oral hygiene, you can also diminish extrinsic staining with a bleaching application.

There are two basic ways to approach this: with either a professional application at our office or with a home kit purchased at a pharmacy or retail store. Although both types use similar chemicals, the professional application is usually stronger and the whitening effect is obtained quicker and may last longer.

Discoloration can also occur within a tooth, known as intrinsic staining, and for various reasons. It can occur during tooth development, as with childhood overexposure to fluoride or from the antibiotic tetracycline. Poor development of enamel or dentin (the main sources of natural tooth color), tooth decay, root canal treatments or trauma are also common causes of intrinsic discoloration.

There are techniques to reduce the effects of intrinsic staining, such as placing a bleaching agent inside the tooth following a root canal treatment. In some cases, the best approach may be to restore the tooth with a crown or porcelain veneer. The latter choice is a thin layer of dental material that is permanently bonded to the outer, visible portion of the tooth: it’s life-like color and appearance covers the discoloration, effectively renewing the person’s smile.

If you’ve been embarrassed by stained teeth, visit us for a complete examination. We’ll recommend the right course of action to turn your dull smile into a bright, attractive one.

BeSuretoHaveaDentalExamBeforeWhiteningYourTeeth

You’ve been embarrassed for a while now by your yellowed, dull teeth. You’re ready for a change.

There’s a simple and cost-effective way to make that change: you can temporarily brighten your smile with teeth whitening, possibly at home. But before you try it, you should first have a dental examination to find out if whitening is the right choice for you.

First off, healthy teeth with outer enamel staining are the best candidates for whitening. Teeth and gums with tooth decay or periodontal (gum) disease should be treated first before undergoing whitening. A dental exam will uncover any health issues you may have with your mouth.

In the same vein, you’ll want to consider whitening carefully if you have dental work like veneers, crowns or implants. Unlike natural teeth, these non-biological materials won’t be affected by the bleaching agent. We can discuss any potential for color mismatch between your whitened natural teeth and your dental work during your examination.

A dental exam can also uncover one other crucial fact — what kind of tooth staining you have. There are two basic types: extrinsic, staining on the outside enamel as we’ve mentioned earlier; and intrinsic, staining that originates from inside a tooth. The whitening kits you purchase from a store and even some of the whitening techniques we use in the office only diminish extrinsic, not intrinsic staining. To address an intrinsically-stained tooth requires a much more involved, invasive clinical technique only performed by dental professionals.

Finally, a dental examination is a good discussion forum for helping you decide between a home kit and a clinical procedure. While DIY kits are effective for the most part, you won’t be able to precisely control the degree of brightness like we can. This could be important if you want a specific shade of whiteness, from a more subtle and natural shade to dazzling “Hollywood” bright. Shade control could also help minimize color mismatch with dental work.

In the end, we want to help you make the best choice for teeth whitening. Even if you decide to pursue whitening at home, we can offer you valuable advice on what to look for when you buy a kit and how to use it. That alone could help ensure you get the new, bright smile you desire!

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.

TestYourKnowledgeFrequentlyAskedQuestionsAboutToothWhitening

What causes stains on teeth?

Staining can occur on the outside surfaces of teeth and is caused by foods such as red wine, coffee, and tea, as well as by tobacco use. They can also be developmental, affecting the structure of the teeth due to excessive fluoride levels or from tetracycline antibiotics given during childhood to name a few. Changes in a tooth's enamel or dentin during tooth formation, or as teeth age, can also cause discoloration.

What is going on inside a tooth's structure that makes it look stained?

Most of a tooth's covering (95 percent) is composed of highly mineralized enamel. The crystals of enamel are contained in a framework, or matrix, of organic matter. Dentists believe that various organic compounds that get into this matrix can cause staining.

How do whiteners work?

Tooth whiteners or bleaches expose the teeth to a peroxide compound. This creates reactive oxygen that breaks down highly colored organic compounds within the tooth's sub-surface matrix, making the tooth look whiter, but without changing its internal structure.

What professional in-office whitening techniques are available?

During treatment, a high concentration of peroxide solution in the form of a gel is applied directly on the teeth, often with activation by a heat or light source. These systems use custom tailored trays fitted to an individual's mouth. Silicone barriers or protective gels are used to keep the peroxide gel away from the gums or sensitive membranes in the mouth.

How are professional home whiteners different?

Home whiteners involve a less concentrated solution of peroxide in a gel form. It is delivered to the tooth surface by a bleaching tray that is custom-made in your dentist's office. Over-the-counter whiteners such as whitening strips or paint-on formulas can also be used, but they take longer and they're not as effective — the more diluted solutions are used for safety.

Can toothpastes really whiten teeth?

Mild abrasives in toothpastes clean surface stains but cannot change the underlying tooth color or remove significant staining.

How long do the results last?

Usually, the results last from six months to two years, but effects will diminish over time. You can make them last longer by avoiding the foods and habits that cause staining.

Are teeth whiteners safe to use?

Teeth whitening products are safe if used according to our recommendations or the product manufacturer's directions. Peroxide products may be toxic if used in excess of recommended intervals and amounts.
