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.

Periodontal (gum) disease is an aggressive bacterial infection caused by built-up plaque on tooth surfaces. Gum disease results in bone loss and causes loss of attachment from the teeth, leading to eventual tooth loss.
The goal of any gum disease treatment is to remove as much plaque and calculus (hardened deposits of plaque) from the gums and teeth as possible. Scaling with special hand instruments or ultrasonic equipment is the basic technique for plaque and calculus removal above and below the gum line. As the infection spreads below the gum line, it can widen the natural gap between teeth and gums to form voids known as periodontal pockets that fill with infection. Accessing and cleaning these pockets, which can occur as deep as the tooth roots, will require more invasive procedures.
Pockets that form at a depth greater than 5 mm below the gum line will most likely require surgical access through the gum tissue. But for pockets not quite that deep there’s an intermediary technique called root planing without surgical intervention. As the name suggests, the roots are physically “planed,” much like shaving a wooden board to remove minute layers of wood.
Using similar instruments as with scaling, root planing removes calculus, bacteria and other infected matter adhering to the root surfaces. It’s best to perform the procedure with local anesthesia to numb the gum tissues, which may be quite sensitive depending on the degree of infection. Working in a pain-free environment also helps us to be as thorough as possible in detecting and removing every bit of plaque and calculus we can find.
In advanced cases, it may be necessary to perform this procedure during multiple visits. As plaque and calculus are removed the inflammation in affected tissues will begin to subside, revealing more deposits of plaque and calculus. It’s also important to begin and maintain a daily habit of effective brushing and flossing to lessen the chances of a recurring infection.
Treating gum disease is an ongoing effort that requires constant monitoring and sustained efforts to remove plaque and calculus, including root planing. Saving your teeth, however, is well worth the effort.

You may be among the one in three Americans who suffer from the pain of tooth sensitivity. Before attempting treatment, though, we must first identify the cause.
Your teeth are made of layers of different organic tissue. The pulp at the center of the tooth contains nerves that transmit pain or pressure sensation to the brain. The pulp is encased by dentin, a layer of tissue composed of tiny tubules that conduct temperature and pressure changes from outside the tooth to the pulp nerves. The hard outer enamel shell shields the dentin from over-stimulation from these sensations.
There are, however, some instances where the dentin may become exposed and cause sensitivity in the tooth. This can occur when the gum tissue recedes and the root of the tooth is exposed to the oral environment. If the root loses its surface coating (referred to as cementum, a cement-like outer layer around the root surfaces) because of over-aggressive brushing (too hard for too long) or advanced periodontal (gum) disease, sensitivity is often the result.
Another instance is enamel erosion. Although made of the hardest substance in the human body, enamel has one major enemy — acid. A high oral acid level brought on by over-consuming acidic foods and beverages or as a symptom of gastric reflux disease dissolves (de-mineralizes) the enamel’s mineral content. Brushing just after eating actually contributes to de-mineralization because the enamel is in a softer state. It requires forty-five minutes to an hour for your saliva to neutralize acid and restore minerals to the enamel — you may actually be brushing away enamel with this practice.
Once we know the underlying cause, we can use an appropriate method to reduce sensitivity. One way is to reduce nerve sensitivity in the dentin’s tubules or block them altogether. There are several chemical products for both home and dental office application that can reduce sensitivity and encourage enamel re-mineralization (as can the fluoride added to toothpaste). We can also strengthen enamel and provide a mechanical barrier to acid through concentrated fluoride in a varnish applied to tooth and root surfaces. And, life-like restorations like crowns or veneers not only improve the appearance of your teeth, they can also provide coverage for exposed dentin.
If you are experiencing painful sensitivity, make an appointment to visit us. Once we know the source, we can treat the problem and reduce your discomfort.
