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.

Clothing and hair styles may come and go, but a dazzling smile is always in fashion! If you're considering options for perking up your appearance, brightening your pearly whites is a quick and affordable way to achieve eye-catching results.
You have several choices when it comes to teeth whitening. But to get the safest, most appropriate, and most satisfying results, you should start with a proper dental examination. A professional assessment of your oral health can determine the cause of your tooth discoloration and may reveal the need for a particular treatment before, or in addition to brightening the color of your teeth.
When we talk about teeth whitening, we generally are referring to “bleaching,” which actually returns your teeth to their natural tooth color. A thorough cleaning — generally part of a routine checkup — often can remove surface discoloration/staining (such as coffee, tea, tobacco or red wine).
There are basically three approaches for external bleaching/whitening of your teeth. They vary based on the strength of the bleaching solution, method of application, duration of treatment, and cost considerations.
Professional In-Office Whitening. This approach involves the carefully controlled application by a dental professional of a powerful and fast-acting concentration of hydrogen peroxide gel. Professional whitening can achieve the most significant color change in the shortest amount of time, but it is pricier than the other options.
Professionally Dispensed Take-Home Whitening Kits. These include a lower-strength peroxide gel applied via flexible plastic bleaching trays custom made by our office specifically for your teeth. The tailored fit of the trays helps ensure an even and thorough coating. A more affordable option than the in-office procedure, it also requires more time to achieve similar results.
Over-the-Counter Products. These feature the lowest-concentration bleaching gel, which is applied to the teeth using one-size-fits-all trays or strips, or a paint-on applicator. While they are the least expensive option, they take the longest to achieve maximum results and may not reach all teeth.

If a glance in the mirror reveals stained or discolored teeth that are detracting from your self-confidence, it's time to do something about it. The first step is to make an appointment for an office visit to find out how we can help you.
External (extrinsic) stains that form on the surfaces of teeth are usually caused by beverages such as red wine, tea, coffee as well as unhealthy habits like tobacco use. Extrinsic stains generally come in shades of browns, black or grays, but may even be orange or green from color producing bacteria.
Internal (intrinsic) stains are part of the structure of the tooth and cannot be removed by polishing. Among their causes are excessive fluoride levels or tetracycline antibiotics given in childhood and during tooth formation. Teeth do become more yellow and discolored as we age. Discoloration of individual teeth may be indicative of tooth decay, or teeth that have had root canal treatment and have literally lost their vitality tend to darken over time. Internal discoloration comes in a variety of shades and hues from yellows, grays, browns, and even some reds or pink.
Five Ways to lighten, whiten and brighten stained or discolored teeth
- Change your habits. Reduce or stop consuming or using foods, drinks or tobacco if they are staining your teeth.
- Improve your daily oral hygiene. Make sure to brush your teeth well, twice a day. Change to a toothpaste that contains a mild abrasive. Some toothpastes also contain tooth whiteners.
- Visit our office for a professional cleaning and polish. Routine scaling and polishing will remove most superficial external stain and discoloration. Sometimes ultrasonic cleaning (by high frequency vibration) and polishing with slightly abrasive pastes may just do the trick.
- Treatment for internal stain and discoloration. Brown colored decaying teeth need to have the decay removed and the teeth restored. Stained old and leaking fillings may also need to be replaced.
- Tooth whitening by bleaching. Bleaching or tooth whitening is a safe and effective way to brighten stained teeth. Internal tooth bleaching can whiten even discolored root canal treated teeth. Ask us for more information about this technique.
If your mirror tells you that your smile needs attention, there's no time like the present to get started. Get back your bright, white smile and your self-confidence as well.
