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.

There are many ways to brighten and whiten teeth if they become dull and stained; but if you know the causes of staining on teeth, you may be able to avoid it in the first place. Here are some of the main causes of stained teeth. We hope this will help keep your smile stain-free.
- What we call extrinsic staining occurs when stain-producing substances collect on the enamel surface of your teeth. To stop or slow this process, cut down on consumption of coffee, red wine, and tea, which contains high tannin contents.
- Cut down on smoking. Tobacco can stain teeth, so it's best to stop the use of tobacco in any form.
- Some mouthwashes and toothpastes contain substances that can cause tooth staining. Mouthwashes containing chlorhexidine, a prescription antibacterial mouthrinse, or those containing cetylpyridium chloride, can cause dental staining after long-term use. Some toothpastes contain stannous fluoride, which can also induce brown discoloration.
- Dry mouth, a common problem, may contribute to extrinsic discoloration. This problem is sometimes a side effect of medications you are taking and drinking more water can often alleviate it. If drugs are the cause of mouth dryness, a consultation with your physician should be considered.
- Bacterial buildup by chromogenic (color or stain producing) bacteria in your mouth can cause staining. Hundreds of bacteria normally live in your mouth, and it is important to keep good regular dental hygiene habits to prevent bacteria from accumulating on your teeth and gums.
- Stains that are caused by various organic compounds that build up within the mineral matrix of your tooth's enamel are called intrinsic stains. They may be caused by tooth decay within the tooth or between the tooth and dental filling materials. Tooth decay is brown, it not only discolors teeth, but it also destroys tooth structure.
- Use of some medications, such as tetracycline antibiotics, can cause intrinsic staining.
Make an appointment for an examination and assessment of your teeth, so that we can determine why they are developing stains. Once we know the cause, we can draw up a plan for whitening and brightening your teeth.
Dental professionals sometimes use specialized words, and you may not be clear about exactly what we mean. Test yourself on some of the specialized vocabulary concerning tooth whitening. How many of the following can you define correctly?
A method of making yellow, discolored teeth whiter. It is relatively inexpensive and safe, with few side effects.
2. External or extrinsic staining and whitening?
Extrinsic staining mainly results from diet and smoking. For example, foods such as red wine, coffee and tea can produce extrinsic stain. Teeth with these stains are bleached by placing whitening substance in direct contact with the living tooth surface.
3. Internal or intrinsic staining and whitening?
Intrinsic tooth discoloration is caused by changes in the structure of enamel, dentin, or pulp tissue deep within the root of the tooth. When the discoloration originates with the pulp tissue, root canal treatment may be needed to whiten the tooth from the inside.
4. Chromogenic material?
Color generating material that may get incorporated into the tooth's substance. It can be a result of wear and aging, or can be caused by inflammation within the tooth's pulp.
5. Carbamide Peroxide?
A bleaching agent discovered in the 1960s and frequently used for tooth whitening. When used, carbamide peroxide breaks into its component parts, hydrogen peroxide and urea, which bleach the colored organic molecules that have been incorporated between the crystals of the tooth's enamel.
6. Power Bleaching?
This technique is used for severely stained tooth. It uses a highly concentrated peroxide (35 to 45 percent) solution placed directly on the teeth, often activated by a heat or light source. This must be done in our office.
An antibiotic used to fight bacterial infections. It can result in tooth staining when taken by children whose teeth are still developing.
8. Rubber Dam?
Use of strong bleaching solutions requires protection for the gums and other sensitive tissues in your mouth. This is done using a rubber dam, a barrier to prevent the material from reaching your gums and the skin inside your mouth. Silicone and protective gels may also be used.
9. Whitening Strips?
Strips resembling band-aids that you can use in your home to whiten your teeth. They generally contain a solution of 10 percent or less carbamide peroxide gel. When using them, be sure to read the directions and follow them strictly to avoid injury or irritation.
10. Fade Rate?
The effects of bleaching may fade over time, from six months to two years. This is called the fade rate. It can be slowed down by avoiding habits such as smoking, along with food or drink that causes tooth staining.
If you are pleased with your smile except for that one front tooth that appears darker, then we have good news for you. Often a tooth appears darker as a result of trauma that may have occurred years ago. Your tooth may need root canal treatment or may have already had root canal treatment in the past. Regardless, you can whiten this tooth via a process called internal bleaching. And as the name suggests, the tooth can be bleached from the inside out. Here's a brief summary of how this entire process works:
- Performing an x-ray exam: The first step is to take a radiograph (x-ray) to make sure that your root canal filling is intact adequately sealing the root canal and the surrounding bone is healthy.
- Making an access hole: To apply the bleaching agent, a small hole will need to be made in the back of your tooth to apply the bleach. However, before doing that, the area must be thoroughly cleaned and irrigated.
- Sealing above the root canal filling: This step is critical to prevent the bleach from leaking into the root canal space.
- Applying the bleach: To obtain the whitening needed, it typically requires between one and four office visits for additional bleaching.
- Applying a permanent restoration: Once your tooth has lightened to the desired color, a permanent filling will be placed over the small hole to seal your tooth's dentin. This is then covered with tooth-colored composite resin (filling material) so that the access hole is undetectable to the naked eye.

Christie Brinkley's world-famous smile has graced the covers of countless magazines for over 30 years. In fact, in her own words from an interview with Dear Doctor magazine, the supermodel said, “I think my smile was really my passport to success in the modeling industry.” And while most of her smile's appeal comes naturally, Christie does give it a boost with good oral hygiene, regular dental checkups and tooth whitening. As Christie says, “When it comes to teeth, keep it as natural as possible. Do not go overboard on whitening. You want your teeth to compliment your faceÃ¢Â€Â¦your friends should not be required to wear sunglasses when you smile!”
Aside from some potential minor side effects such as tooth sensitivity, whitening teeth through bleaching is a relatively inexpensive way to brighten your smile conservatively and successfully. There are three common methods, as described below:
- An external or vital approach where “vital” (living) teeth are bleached through direct contact to the tooth's surface.
- An internal or non-vital approach where the tooth is whitened from the inside during a root canal treatment.
- A combination approach in which both internal and external bleaching techniques are used.
But what causes teeth to become discolored?
Tooth discoloration can be caused by a traumatic blow to your teeth resulting in nerve tissue (pulp) death. However, there can be many other causes: consuming or using products that stain the teeth such as coffee, tea, cola, tobacco products and red wine, to name just a few. Aging is another factor, as it results in changes in the mineral structure of the tooth as the enamel, the outermost layer, loses its beautiful and youthful translucency. Other causes include exposure to high levels of fluoride; tetracycline, an antibiotic, administered during childhood; inherited developmental disorders and jaundice in childhood; and tooth decay.
The good news is that we routinely brighten smiles through tooth whitening.
