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.
Some of the most popular smile enhancers on the market today are both over-the-counter (OTC) and professional teeth whitening products. And while studies indicate that bleaching can successfully achieve noticeable increases in whitening of stained teeth, there are some facts you need to know about these products and the results that they can deliver.
- Nearly all bleaching products contain the same basic ingredient, carbamide peroxide or its breakdown product, hydrogen peroxide. However, the products our office uses to professionally whiten your teeth are much stronger without compromising the health and safety of your teeth, gums, and mouth.
- OTC bleaches typically contain no more that 10% carbamide peroxide while professional bleaches can contain between 15% and 35%. And to make professional bleaching even more effective, we may use them in combination with specialized lights or lasers.
- Bleaching is NOT a permanent solution and thus results will diminish over time. The “fade rate” begins to occur 6 to 12 months after treatment.
- While you can't avoid the fading process, you can extend your bleaching results by avoiding foods and drinks that stain your teeth, such as red wine, red (tomato-based) sauces, coffee, tea, sodas/colas, and blueberries to name a few.
- Another method for extending your results is to use a straw when drinking beverages that can stain your teeth so that the liquid does not come in contact with your teeth.
- If you have visible crowns and/or veneers mixed with your natural front teeth, it may be quite difficult for you to bleach your natural teeth so that they perfectly match your veneers or crowns. Remember, tooth whitening is not effective on crowns, veneers, bridgework, or any type of artificial tooth.
- One of the most common side effects of whitening teeth is tooth sensitivity and irritation of the gum tissues. They both are usually temporary and often occur when you start bleaching; however, they generally subside after a few days.
Overall, bleaching your teeth is an effective way to brighten your smile with minimal side effects. If it is something you are interested in pursuing, talk it over with us first — even if you plan to use OTC products — so that you have a clear understanding about your specific options and projected outcomes.

Dental implants are a fascinating treatment option that can be life changing when used properly. They have also experienced tremendous scientific advancements and press over the years making them highly desirable by people of all walks of life. See how much you really know about dental implants by taking our quick and easy true/false self test.
- Dental implants can produce lifelike results that are indistinguishable from natural surrounding teeth.
True or False
- Many dental professionals consider dental implants as a “third set of teeth,” as they can last a lifetime when properly maintained.
True or False
- A dental implant is a safe option that is suitable for all patients regardless of age.
True or False
- When properly placed and maintained, dental implants have a 90% success rate.
True or False
- If you do not have enough bone to support a successful dental implant, there is not much that can be done.
True or False
- When teeth are missing, the face tends to have a sunken-in appearance called, “posterior bite collapse.”
True or False
- One of the positives of dental implants is that they do not affect adjacent teeth.
True or False
- Dental implants typically cost significantly more than other options, such as a bridge, over the course of a lifetime.
True or False
- Dental implants are always more desirable than bridgework or other treatment options for missing teeth.

When you have your teeth bleached in a dental office, the results almost seem like magic. Let's push aside the magician's cape and see what is really happening in professionally-applied, in-office tooth whitening.
How do teeth become discolored?
A tooth's enamel covering is mostly composed of mineral crystals. At a microscopic level, you can see a framework or matrix of organic (living) matter interspersed between the crystals of enamel creating a very irregular surface capable of retaining stains. Chromagenic (color generating) organic compounds can become part of this organic matrix resulting in tooth staining. They can be bleached without affecting the mineral structure of the tooth's enamel.
As people get older and their teeth wear, the enamel loses its youthful translucency and the underlying layer, called dentin, thickens and becomes more yellow. Such changes to the actual tooth structure are called intrinsic staining. Other causes of intrinsic discoloration are exposure to high levels of fluoride or tetracycline antibiotic administration during childhood, tooth decay, or root canal problems, among others. Discoloration can also be caused by external staining from certain foods, drinks, or tobacco products. Such surface stains are called extrinsic staining.
Behind the Magic
Materials used for tooth bleaching are hydrogen peroxide and carbamide peroxide. Peroxides are commonly used as bleach, and you may have seen them used as hair bleaches, for example. Hydrogen peroxide is a strong oxidizing agent that attacks the organic molecules responsible for tooth discoloration, bleaching them until they lose their color. Carbamide peroxide also contains urea, which is a compound that permits the peroxide to remain in contact with the teeth for longer amounts of time without harming them.
Often called power bleaching, the in-office technique uses a high concentration of peroxide solution (35-45% hydrogen peroxide), placed directly on the teeth in the form of a gel. A heat or light source may enhance the peroxide release. The gel is applied with trays custom fitted to your mouth, and specific barriers are applied to protect sensitive gum tissue from the solution. Results show teeth becoming up to ten shades lighter in about an hour.
In-office bleaching under the supervision of my staff and me is recommended if you have severely stained teeth, and particularly if you are about to have veneers or crowns made. It's a way to rediscover the pearly translucency of your youthful smile.
Designing a better smile sometimes requires a change in the size, shape, or color of your teeth. Porcelain laminate veneers (thin layers of dental ceramic material) enhance your appearance by replacing the natural enamel on the outside of your teeth. A veneer is physically bonded to the surface of a tooth, in essence, becoming part of it.
Traditionally, a small amount of the natural tooth enamel is drilled away to allow room for the veneer. But today, in some circumstances, it is possible to use an approach where enamel reduction or preparation is not necessary because the veneers can be bonded directly onto the tooth's natural surface. These are called “Prepless” or “No-prep” veneers, and are used to create aesthetically pleasing and natural looking restorations. An advantage of the prepless procedure is that the process is reversible so that you can give your new smile a “test drive.”
You may be a good subject for Prepless veneers if:
- Your smile is narrow because the teeth in the sides of your smile are positioned inward and do not show from a frontal view.
- There is spacing between your teeth, and the teeth appear too small.
- You have a fairly common genetic condition in which one or both of the teeth directly next to the two upper front teeth are very small and peg-shaped.
- There is an imbalance between the size of your lips and teeth (large lips and small teeth), which are not in proportion to show off your best smile.
Prepless veneers are probably not for you if:
- Your teeth are not aligned properly in your bite.
- Your teeth are very crowded, resulting in poor facial profile.
- Your teeth are already relatively large or positioned forward.
In these cases you may need to have some form of orthodontic treatment to move your teeth into better position. Sometimes veneers can be used to create an illusion of proper tooth alignment, but some amount of tooth reduction may be required.
We can assess whether prepless veneers are right for you. There is no substitute for an expert dentist's talent and expertise with the various cosmetic techniques available today. These skills combined with a thorough diagnostic evaluation, and a clear understanding of your goals, are the keys to providing you with a successful and beautiful smile.
