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.

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.

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.

There are many reasons why teeth may need a whitening treatment to achieve an appealing brightness: what we eat and drink, natural aging, genetics, and the lack of dedication to oral hygiene can all play a role in how we look.
For vital (living) teeth, there are basically three different options for teeth whitening, and we’d be happy to help you decide which is right for you:
- In-office tooth whitening: The fastest way to get your smile radiant. A high concentration of a peroxide gel solution is applied directly to the tooth surface. Gums and other soft tissues are completely protected for your safety. This technique is excellent for whitening deep surface stains as well as general tooth whitening. This professional treatment requires the least amount of time to achieve the desired whiteness.
- The professional take-home option: Custom-made bleaching trays are prepared by our office. This technique is convenient and less expensive, but the desired whiteness will take longer to achieve than the in-office option.
- Over-the-counter products: These offer the least expensive option but use weaker whitening agents. For example, whitening strips, like the ones advertised on television, are popular and easy to use but will generally take the most time to achieve the desired success. Also, even agents that are not the strongest available may cause damage to teeth if used inappropriately and without professional supervision.
While there are normally no serious side effects after professional whitening treatments, there is a potential risk of tooth sensitivity and gum irritation. If either one or both of these occur, it should disappear within a few days.
It should come as no surprise that bleaching is not permanent. The whiteness will fade eventually depending on your diet, habits, hygiene, etc., but it usually will last at least six months — more often up to two years. Obviously, if you avoid drinking coffee, tea, or red wine, don’t smoke, and have a diligent oral hygiene routine your results may last longer.
Advertisements for teeth-whitening products are everywhere. If you have any questions about what you see, or simply want to do a reality check on their claims, please contact us or schedule an appointment for a consultation.

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.

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.
