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.

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.

You’re satisfied with your smile appearance except for one thing — your teeth aren’t as white and bright as you wish they could be. So, you’ve decided to do something about their dull yellow color.
You’re also thinking about buying a whitening product you can use yourself rather than a professional application. But you still want the answers to two questions: are home whitening kits safe? And, are they effective?
By and large the answer to the first question is yes — if you use it as directed. The whitening agents in FDA-approved products are in safe proportions to other ingredients and won’t cause any major health issues. That said, if you go beyond the instructed dosage you could damage your teeth, especially your enamel, and cause long-term problems with your dental care.
In addition, if you (or a family member) are still in your early teens, you may want to wait until you’re older. Although most permanent teeth have come in by puberty, their enamel still needs to mature. The chemicals in a whitening kit could be too strong for their under-developed enamel. It’s best to get our advice on whether your teeth are mature enough for whitening.
As to their effectiveness, home whitening kits should perform as their labeling indicates. But there are some differences in effects between a home kit and a professional application.
Although a home kit usually uses the same whitening agents (like carbamide peroxide), its strength is much lower than a professional treatment — about 10% of volume compared to around 30% in clinical solutions. This means it will take much longer to achieve the desired whitening effect that a professional application can in fewer sessions, and with less precision. In addition, home kits are only effective on surface staining of the enamel — discoloration within a tooth requires treatment by a dentist.
You can get satisfactory results from a home whitening kit. But before you make a purchase, consult with us first — we can advise you on what to look for in your purchase, as well as determine if your teeth can benefit from whitening at home.

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,Â 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.

In modern society, a bright, white smile conveys optimal health, youth and sound teeth. However, various influences including age, wear, diet, and lifestyle may prevent you from having and maintaining the glistening smile you long to share with the world. Luckily, there are many safe, inexpensive, and successful treatment options for discolored or stained teeth.
We can perform a “power bleaching” in our office to whiten teeth that are severely stained or discolored. This procedure whitens the external surfaces of the teeth by using a high concentration (35-45%) hydrogen peroxide solution, which is sometimes activated by a specialized light. To prevent irritation of the mouth's soft tissue lining during this procedure, we will isolate your gums and membranes with a rubber dam, a silicone or other effective barrier. Professionally applied in-office power bleaching provides control, speed, and predictability capable of lightening teeth up to ten shades in an hour. Don't try this at home! Our staff will take precautions in the office to avoid side effects and possible tooth sensitivity.
We can also provide you with custom-made, vacuum-formed, plastic bleaching trays for use with a take-home whitening application. In this instance, a gel made from carbamide peroxide (4-7% hydrogen peroxide, safe for home use) is delivered to the tooth surfaces in the bleaching trays. You will need to wear the tray for 30 minutes twice a day, which is a longer process than in-office bleaching. The first subjective signs of whitening will occur after three or four sessions, allowing whitening of up to eight shade units.
Another home-based option, whitening strips, essentially look like band-aids for the teeth. They are capable of lightening teeth by about three shades after being worn directly on the surface of the teeth for 30 minutes twice a day for one week.
If you have always wanted whiter teeth, schedule an appointment so we can determine which of these treatment options would work best for you. For more information on the fundamentals of teeth whitening, read the informative Dear Doctor magazine article “Teeth Whitening: Brighter, Lighter, Whiter...”
