Whitening can transform the dullest teeth into a dazzling smile fit for a Hollywood star. But before you undergo a whitening procedure, you might have a few questions about it. Here are the answers to a few of the most common.
How white can I go? In an office application we can adjust the solution and application time to control the level of shade (dark or light) from subtle to dazzlingly bright. The real question, though, is how much color change will look best for you? A good rule of thumb is to match the shade in the whites of your eyes.
Whitening will improve poor dental conditions…right? Not necessarily. Besides foods, beverages or poor hygiene, decay, abscesses or problems from root canal treatments can also cause discoloration. In some dental situations, whitening could make your smile less attractive. If, for example, you have exposed roots due to gum recession, those areas won't bleach like the enamel and could make their exposure stand out more. Better to try and repair these problems before whitening.
What effect will teeth whitening have on my dental work? None â??composite or ceramic materials won't lighten. The real concern is with creating a situation where whitened natural teeth don't match the color of dental work. Depending on the location of your veneers, crowns or other bridgework you could have a color mismatch that will look unattractive. We would therefore need to take your dental work into consideration and adjust the shading accordingly.
Will teeth whitening work on any stained teeth? That depends on the cause of the staining. If it's on the enamel, then external bleaching techniques should work. If, however, the discoloration comes from inside the tooth, then only a dental procedure that applies a bleaching agent inside the tooth can alleviate that kind of discoloration.
So after whitening, I'm good to go? Well, not permanently. Eventually the brightness will diminish or fade, usually in six months to two years. You can, of course, prolong the fade rate by not using tobacco, cutting back on staining beverages like red wine, tea and coffee, practicing daily oral hygiene and visiting us for regular office cleanings and other dental work. We can also touch up your existing whitening during your visits.

A relatively easy and inexpensive way to improve your smile is to whiten your teeth. In fact, you may even be able to do it yourself at home. Although there are differences between at-home and professional whitening, the former can still be effective.
That effectiveness, though, might be dependent on how well you understand what home whitening can do and what it can’t. So before you purchase your kit, here are a few things to know about DIY teeth whitening.
Home kits are safe—when used as directed. Although nothing in life is completely risk-free, home whitening kits are relatively safe. But only if you follow the directions: If you overuse the bleaching solution beyond its intended use, you could wind up with permanent damage to your tooth enamel that can be costly to treat.
Bleaching solutions are relatively mild. Nearly all home kits use carbamide peroxide, a form of hydrogen peroxide, as their bleaching agent. Home kits usually contain no more than 10% of this agent, much lower than professional solutions. Used as directed, this amount of bleaching agent poses little to no risk to dental or general health. On the other hand, the weaker home kit solution does limit the extent of brightness you can achieve compared to stronger professional treatments.
For top results (or certain conditions), consider professional whitening. While you can obtain good results with a home whitening kit, professional whitening provides more precise brightness control and range, and may possibly last longer. That’s because your dentist has more advanced techniques and equipment, as well as stronger bleaching solutions. And, if your discoloration originates inside your teeth, a home kit won’t help—only a dentist can address that kind of discoloration.
Even if you decide to “go solo,” your dentist can still give you advice on what to look for in a home kit, as well as tips for the actual procedure. But whether you whiten at home or let your dentist do it, teeth whitening can take years off your smile and give you a more attractive look.

Like many who have risen to the top tier in show business, singer Taylor Hicks found that he needed a few things (besides talent, of course) to really succeed: a willingness to seek out opportunities and work hard; a unique and energetic stage presence; and a bright, appealing smile.
“Everyone wants to have a great smile,” Hicks recently told Dear Doctor magazine. “In my business, it’s one of the most important things. A lot of what I do is smiling and having fun, being in front of the camera and taking pictures.”
To help him keep his smile sparkling, Hicks opts for in-office whitening treatments from his dentist. These treatments are a safe, quick and effective way to lighten teeth by 3 to 8 shades in a single one-hour visit. Best of all, you don’t have to be an American Idol winner or a Las Vegas headliner to take advantage of them — in fact, we offer them right here in our own office.
Why choose in-office treatments instead of take-home trays (or over-the-counter products)? While each system can be effective at lightening teeth to some degree, the in-office method offers several distinct advantages. For one, it’s the fastest way to get your teeth as bright as they can be; the same lightening that can be achieved in one office visit could take a week when done at home, using custom-made trays and dentist-supplied bleaching solutions — and several weeks with over-the-counter products! So if your time is limited, in-office treatment is the way to go.
Plus, in-office treatments are performed under our direct supervision. That means we can safely use the most powerful whitening gels, and achieve the maximum control over the result. This can be important when you have crowns or replacement teeth such as implants, which Hicks has. Artificial crowns don’t whiten like natural teeth, so it’s important to get just the right degree of lightening to produce an evenly bright smile.
The bottom line, of course, is the result: a dazzling white smile. “In entertainment, a big, pearly white smile makes a difference,” Hicks said. But you don’t have to be an entertainer to enjoy the benefits of a brilliant smile — we do it for plenty of “regular folks” too.
So if your smile could use a little brightening, why not call us and schedule an appointment for whitening treatment? You can learn more in the Dear Doctor magazine articles “Teeth Whitening” and “Important Teeth Whitening Questions Answered.”
You have a beautiful smile, but you hesitate to show it because of your stained teeth. Fortunately, whitening techniques could take away that embarrassment.
There are two basic types of tooth staining or discoloration: extrinsic, in which the stain is on the surface of the teeth and mostly caused by substances like coffee, wine or tobacco; and intrinsic, which occurs deep within the tooth, caused by such factors as aging, previous dental treatments and fillings, the use of antibiotics (tetracycline, predominantly), or over-exposure to fluoride.
Whitening or bleaching is an effective and relatively affordable solution for many instances of both intrinsic and extrinsic staining. Bleaching solutions are available in over-the-counter (OTC) home kits or as a professional application in the dental office.
Most bleaching solutions use carbamide peroxide, a chemical compound that is effective in removing most stains. OTC home applications contain carbamide peroxide (or an equivalent) in concentrations of about 10% as opposed to 15-35% found in professional solutions. Though less costly than a professional application, OTC products take longer (usually up to three weeks) to achieve desired results. With its stronger solution, a professional application in our office can achieve the same level of brightness in only one or two visits. We may also use special lighting to accelerate the chemical process, as well as rubber dams or gels to protect gums and soft tissues from solution irritation during the procedure.
Although effective, whitening isn't a permanent solution — over time the effect will fade, usually six months to a year depending on how you care for your teeth. Matching tooth color can also be difficult in some cases, especially if you have a mix of natural teeth and artificial crowns or bridges. And, whitening may not be adequate for some types of staining.
Regardless of which application you wish to use — OTC or professional — it's a good idea to visit us first for a professional consultation. We can recommend whether whitening is a good choice for your particular type and level of staining, or if some other option like porcelain veneers might be the better choice. Regardless, there are solutions to the problem of staining, and a way to gain a brighter smile.

When you have your teeth bleached in a dental office, the results almost seem like magic. Let's push aside the magician's cape and see what is really happening in professionally-applied, in-office tooth whitening.
How do teeth become discolored?
A tooth's enamel covering is mostly composed of mineral crystals. At a microscopic level, you can see a framework or matrix of organic (living) matter interspersed between the crystals of enamel creating a very irregular surface capable of retaining stains. Chromagenic (color generating) organic compounds can become part of this organic matrix resulting in tooth staining. They can be bleached without affecting the mineral structure of the tooth's enamel.
As people get older and their teeth wear, the enamel loses its youthful translucency and the underlying layer, called dentin, thickens and becomes more yellow. Such changes to the actual tooth structure are called intrinsic staining. Other causes of intrinsic discoloration are exposure to high levels of fluoride or tetracycline antibiotic administration during childhood, tooth decay, or root canal problems, among others. Discoloration can also be caused by external staining from certain foods, drinks, or tobacco products. Such surface stains are called extrinsic staining.
Behind the Magic
Materials used for tooth bleaching are hydrogen peroxide and carbamide peroxide. Peroxides are commonly used as bleach, and you may have seen them used as hair bleaches, for example. Hydrogen peroxide is a strong oxidizing agent that attacks the organic molecules responsible for tooth discoloration, bleaching them until they lose their color. Carbamide peroxide also contains urea, which is a compound that permits the peroxide to remain in contact with the teeth for longer amounts of time without harming them.
Often called power bleaching, the in-office technique uses a high concentration of peroxide solution (35-45% hydrogen peroxide), placed directly on the teeth in the form of a gel. A heat or light source may enhance the peroxide release. The gel is applied with trays custom fitted to your mouth, and specific barriers are applied to protect sensitive gum tissue from the solution. Results show teeth becoming up to ten shades lighter in about an hour.
In-office bleaching under the supervision of my staff and me is recommended if you have severely stained teeth, and particularly if you are about to have veneers or crowns made. It's a way to rediscover the pearly translucency of your youthful smile.
