Teeth whitening or bleaching is one of the most affordable and least invasive ways of improving your smile. Although the effect fades with time, whitening can make dull and dingy teeth more attractive in short order.
Teeth whitening is also unique among cosmetic dental procedures in that you can do it yourself at home. While professional bleaching solutions are stronger and capable of greater brightness and longevity, you can still achieve good results with a DIY kit.
If you decide to whiten at home, though, there are a few things to keep mind for a desirable and safe outcome. Here are 3 tips for successful DIY teeth whitening.
Follow the directions. It's not a good idea, both for a successful and safe outcome, to stray away from a kit manufacturer's recommended directions. FDA-approved home kits usually contain 10% or less of carbamide peroxide (one of the more common bleaching agents). That may not seem very strong but it's adequate within the recommended time it remains on your teeth to achieve an effective whitening effect. Exceeding those directions could permanently damage your tooth enamel.
Make sure a home kit will work on your staining. Home whitening kits only affect outer staining on tooth enamel. But dental discoloration can also arise from inside a tooth, often because of trauma, tetracycline use, or as a side effect of a root canal treatment. This kind of internal staining requires a special procedure usually performed by an endodontist to reduce it. So, see your dentist first to make sure your teeth are healthy enough for whitening and that a home kit will work for you.
Get your dentist's advice on home kits. There are a number of whitening applications on the market you can choose, so ask your dentist for recommendations. They can also give you some helpful tips on the whitening process to ensure you'll be safe and successful in your efforts.
Here's a couple of other things to remember to enhance your teeth whitening experience: whether you whiten your teeth at home or with the dentist, be sure you continue to care for your teeth with daily brushing and flossing. And, if you limit your consumption of foods and beverages known to stain teeth, you'll help extend the duration of your brighter smile.

You’ve been embarrassed for a while now by your yellowed, dull teeth. You’re ready for a change.
There’s a simple and cost-effective way to make that change: you can temporarily brighten your smile with teeth whitening, possibly at home. But before you try it, you should first have a dental examination to find out if whitening is the right choice for you.
First off, healthy teeth with outer enamel staining are the best candidates for whitening. Teeth and gums with tooth decay or periodontal (gum) disease should be treated first before undergoing whitening. A dental exam will uncover any health issues you may have with your mouth.
In the same vein, you’ll want to consider whitening carefully if you have dental work like veneers, crowns or implants. Unlike natural teeth, these non-biological materials won’t be affected by the bleaching agent. We can discuss any potential for color mismatch between your whitened natural teeth and your dental work during your examination.
A dental exam can also uncover one other crucial fact — what kind of tooth staining you have. There are two basic types: extrinsic, staining on the outside enamel as we’ve mentioned earlier; and intrinsic, staining that originates from inside a tooth. The whitening kits you purchase from a store and even some of the whitening techniques we use in the office only diminish extrinsic, not intrinsic staining. To address an intrinsically-stained tooth requires a much more involved, invasive clinical technique only performed by dental professionals.
Finally, a dental examination is a good discussion forum for helping you decide between a home kit and a clinical procedure. While DIY kits are effective for the most part, you won’t be able to precisely control the degree of brightness like we can. This could be important if you want a specific shade of whiteness, from a more subtle and natural shade to dazzling “Hollywood” bright. Shade control could also help minimize color mismatch with dental work.
In the end, we want to help you make the best choice for teeth whitening. Even if you decide to pursue whitening at home, we can offer you valuable advice on what to look for when you buy a kit and how to use it. That alone could help ensure you get the new, bright smile you desire!

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.

If you have discolored teeth, the cause is often staining on the enamel surfaces from foods, beverages, or smoking. But tooth discoloration may also originate deep within the root of a tooth. Sometimes this happens to a tooth that had to have earlier root canal treatment because of injury or decay.
In such cases the living pulp tissue and its blood vessels and nerves had to be removed from the root canals, resulting in the death of the dentin layer, which makes up most of the tooth's body. Over time this caused the dentin to darken. The color may come from remains of blood that was left in the tissue, or from filling materials left in the root canal that are showing through.
Since these stains are caused internally (intrinsic) and not on the outside of the tooth (extrinsic) they must be whitened from the inside. This is usually done by putting a bleaching agent into the empty chamber from which the pulp was removed. Usually the bleaching agent is a substance called sodium perborate.
When it is mixed with a solution of hydrogen peroxide, sodium perborate slowly bleaches the color from the tooth's internal material. It is considered to be safe and reliable for this use.
The work begins by taking x-ray images to make sure that the root canal is correctly sealed and the bone is healthy. After this, we will make a small hole in the back of the tooth through which the root canal space will be cleaned. The root canal space will be sealed and the bleach will be applied in a putty-like form and sealed off from the rest of your mouth. Every few days this procedure will be repeated until the bleaching reaches the desired level.
At this point a tooth-colored composite resin will be used to seal the small hole that was made in the dentin to insert the bleach. After the tooth has reached the level of whiteness that matches it to your other teeth, veneers or crowns must sometimes be used to repair the surface if it is chipped or misshapen, for example.

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.
