Picture yourself with a beautiful smile…what do you see? Besides straight and uniform teeth framed by the gums, you should also see one other thing indicative of a great smile—your teeth an attractive shade of translucent white.
But as you age your teeth can begin to dull as the enamel loses its translucency and the underlying dentin thickens and yellows. You no longer have the bright smile you once had in younger days.
But if the discoloration is mainly on the outer enamel, teeth whitening could be your answer for regaining your youthful smile. This is a procedure in which we apply a solution containing a bleaching agent (usually hydrogen peroxide) to your teeth. Aided by heat or light to activate it, the solution can temporarily whiten the enamel.
Teeth whitening isn't an exclusive treatment provided by a dentist—there are a number of retail products that enable you to bleach your teeth at home. But there are distinct advantages to having your teeth professionally whitened.
For one, we can control the level of brightness by adjusting the strength of the bleaching solution. This allows you to achieve the kind of look you want—from a more natural and subtler shade to a more dazzling color often called “Hollywood White.”
Any external teeth whitening application will fade with time, regardless of whether they're professional or DIY. But a dental office whitening may last longer due to our stronger solutions and curing techniques. And, by caring for your whitening (by avoiding tobacco and food items that stain teeth) and obtaining occasional touch-ups in our office, the shine could last for a few years.
Again, this particular whitening technique only works with outer staining and yellowing. If your discoloration originates from inside the teeth, you'll need a more invasive method. And your teeth should be reasonably healthy before undergoing whitening.
All in all, though, teeth whitening is an easy and affordable way to brighten your smile. It could help you take years off your appearance.

Transforming your smile doesn’t necessarily require complex treatments like orthodontics, dental implants or porcelain veneers. Sometimes a little brightness can mean all the difference in the world.
Bleaching (or teeth whitening) is a proven method for dealing with tooth discoloration and staining. Nearly all whitening products, whether home or professional, contain the bleaching agent carbamide peroxide or its breakdown product hydrogen peroxide. These agents effectively diminish staining deep within a tooth (intrinsic) or on the enamel surface (extrinsic), although intrinsic staining will require a more invasive office procedure.
If you have extrinsic staining you have three basic options: dental office bleaching, a retail home kit or a kit purchased from a dentist. Again, you’ll find the same basic bleaching agents in each of these versions. The difference will be the concentration: home kits contain about 10% agent by volume, while the office application will be a much higher range of 15% to 35% (which may also employ specialized lights or lasers to increase the bleaching effect). As a result, an office bleaching may take only a visit or two to achieve the desired brightness while a home kit about two or three weeks.
Whitening is a more economical route for smile enhancement of otherwise sound teeth than other measures. But there are other considerations you should weigh before undergoing a procedure. Whitening isn’t a permanent fix — the brightness will diminish over time, optimally six months to a year in what dentists call the “fade rate.” You can slow this process by avoiding or limiting foods and habits that cause staining.
If you have other dental work — crowns, bridgework or fillings — it may be difficult to achieve a tint level that matches these restorations, especially at home. And while whitening is relatively safe (as long as you’re using your kit as directed), you may experience tooth sensitivity, gum irritation or other minor oral side effects.
Before you decide on whitening, visit us first for a complete dental examination. From there we can advise you on whether whitening is a good smile enhancement choice for you.

Tooth whitening procedures and products have become increasingly popular over the last two decades. There are two main sources of application: professional procedures performed in a dentist’s office; and over-the-counter products for performing whitening applications at home. While there are pros and cons to both approaches, neither type poses a significant health risk — that is, if you match the correct product to the type of staining you have, and it’s applied according to the manufacturer’s instructions.
Although whitening treatments may differ in formula and strength, almost all use hydrogen peroxide as the bleaching agent, usually contained in carbamide peroxide which splits into hydrogen peroxide and urea upon activation. After many studies, there’s a strong consensus that hydrogen peroxide used at the levels found in whitening products doesn’t cause any harm to the body, including as a precursor to cancer.
But as the 16th Century Swiss physician Paracelsus once noted, “All substances are poisons… The right dose differentiates a poison from a remedy.” This is true of the chemicals that make up whitening products — they’re safe unless they’re overused. Going beyond their directions for use could lead to tooth enamel damage.
Further caution is also in order for teenagers using whitening products. Although they may have their permanent teeth (although younger teens may still have some primary teeth), the enamel layer is still developing and can be more vulnerable to damage from whitening chemicals than for adults.
The best approach for both a professional or home whitening procedure is to first seek consultation from our office. If nothing else, you should at least undergo a dental examination to identify the true cause of your teeth’s staining or discoloration. If the discoloration originates within the tooth, home applications and many professional treatments will not help if they bleach the outer surface only. We can also advise you on the proper application and dosage for a chosen product.
Using the right whitening product and in an appropriate manner will reduce the risk of injury to your teeth and overall health. And, the end result can be a brighter, more vibrant smile.

If you're looking to improve the appearance of your smile, tooth whitening treatments — whether done at home or in our office — are a popular option. Here are the answers to some questions that many people ask before they begin the process.
Q: Are commonly used tooth-whitening methods safe?
A: Yes — provided they are used as directed. A large body of research has shown that using the correct concentration of peroxide — the bleach that whitens teeth — for the proper amount of time is not known to cause any major health problems. However, there have been cases where poor-quality bleaching solutions and/or excessive usage have caused deterioration of tooth enamel and extreme gum sensitivity. Always follow our office's recommendation.
Q: Does this mean I have to have in-office treatments to whiten my teeth?
A: No. But you should come in for a thorough dental examination, with x-rays, before you begin whitening treatments. Why? Because if there is trouble with the underlying tooth structure, then whitening the tooth is like painting over rusty metal: It hides the symptom, but doesn't fix the problem. Abscesses and root-canal problems are just two of the underlying causes of tooth discoloration that should be treated before teeth are whitened.
Q: What are some different methods for whitening teeth, and how long do they take?
A: The fastest is in-office whitening treatments, using a strong bleaching solution and appropriate gum protection. Next comes the cost-effective method of at-home bleaching with custom-made flexible plastic trays (sometimes called nightguard vital bleaching.) If you're not in a hurry, over-the-counter (OTC) products can do the same thing — given enough time. One study comparing different whitening treatments found that a six-shade improvement in whitening was accomplished by three in-office treatments. A week was needed for custom-tray bleach applications, or 16 daily applications of OTC products, to achieve comparable results.
Q: Can any tooth be made bright white?
A: No. Every tooth has a maximum level of whiteness, beyond which it can't get any lighter. Furthermore, fillings, crowns and other dental restorations can't be lightened with bleach — another reason to talk to our office; we can help you achieve the best possible look for your particular smile.
Q: How long will my white teeth last?
A: It depends. No whitening method is permanent, but the typical result lasts for up to two years. To preserve that bright smile, you can take some positive steps: Avoid tobacco and beverages that stain, like red wine, tea and coffee; keep up with regular cleanings in our office; and, practice good oral hygiene at home. You can also have a touch-up treatment once or twice a year.
