Whitening can transform the dullest teeth into a dazzling smile fit for a Hollywood star. But before you undergo a whitening procedure, you might have a few questions about it. Here are the answers to a few of the most common.
How white can I go? In an office application we can adjust the solution and application time to control the level of shade (dark or light) from subtle to dazzlingly bright. The real question, though, is how much color change will look best for you? A good rule of thumb is to match the shade in the whites of your eyes.
Whitening will improve poor dental conditions…right? Not necessarily. Besides foods, beverages or poor hygiene, decay, abscesses or problems from root canal treatments can also cause discoloration. In some dental situations, whitening could make your smile less attractive. If, for example, you have exposed roots due to gum recession, those areas won't bleach like the enamel and could make their exposure stand out more. Better to try and repair these problems before whitening.
What effect will teeth whitening have on my dental work? None â??composite or ceramic materials won't lighten. The real concern is with creating a situation where whitened natural teeth don't match the color of dental work. Depending on the location of your veneers, crowns or other bridgework you could have a color mismatch that will look unattractive. We would therefore need to take your dental work into consideration and adjust the shading accordingly.
Will teeth whitening work on any stained teeth? That depends on the cause of the staining. If it's on the enamel, then external bleaching techniques should work. If, however, the discoloration comes from inside the tooth, then only a dental procedure that applies a bleaching agent inside the tooth can alleviate that kind of discoloration.
So after whitening, I'm good to go? Well, not permanently. Eventually the brightness will diminish or fade, usually in six months to two years. You can, of course, prolong the fade rate by not using tobacco, cutting back on staining beverages like red wine, tea and coffee, practicing daily oral hygiene and visiting us for regular office cleanings and other dental work. We can also touch up your existing whitening during your visits.

How do you know if you have periodontal (gum) disease? Sometimes your gums will tell you—when they’re red, swollen or bleed easily.
But your gums can also look and feel healthy while a gum infection still brews below the gum line. In this case, a regular dental visit could make the difference. Even without overt signs of infection, we may be able to detect gum disease with a slender metal instrument called a periodontal probe.
Gum disease is a bacterial infection that most of the time arises from dental plaque. This thin film of bacteria and food particles accumulates on tooth surfaces, especially because of poor or non-existent oral hygiene. A continuing infection can weaken gum tissues and cause them to pull away or detach from the teeth.
Normally, there’s a slight gap between the gums and teeth. But as the infected gums pull away, the gaps grow larger and deeper, forming what are known as periodontal pockets. They become filled with infection that soon spreads to the root and bone and increases the risk of tooth loss.
These pockets, though, could be the means for detecting a gum infection with the help of the periodontal probe. During a dental exam we gently insert the probe, which has millimeter depth markings etched on it, between a tooth and its adjacent gums. While a depth of 1 to 3 mm is normal, a probe measurement of 4 to 5 mm could be a sign of an early stage infection. A reading of 7 to 10 mm, on the other hand, may indicate more advanced disease.
Along with other factors, periodontal probing can be quite useful identifying both the presence and extent of a gum infection and then how to treat it. The goal of any treatment is to remove plaque and tartar (calculus) deposits that sustain the infection. But probing, along with other diagnostic methods like x-rays, could point to deeper infection below the gum line that require more extensive methods, including surgery, sometimes to access and remove the disease.
Achieving the best treatment outcome with gum disease often depends on finding the infection early. Periodontal probing helps to make that discovery more likely.
The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.

Primary (baby) teeth might not last long, but their impact can last a lifetime. Their first set of teeth not only allows young children to eat solid foods, but also guide permanent teeth to form and erupt in the proper position.
Unfortunately, primary teeth aren't immune to tooth decay. If the decay is extensive, the tooth may not last as long as it should. Its absence will increase the chances the permanent teeth won't come in correctly, which could create a poor bite (malocclusion) that's costly to correct.
If a primary tooth is already missing, we can try to prevent a malocclusion by installing a “space appliance.” This keeps nearby teeth from drifting into the empty space intended for the permanent tooth. The best approach, though, is to try to save a primary tooth from premature loss.
We can often do this in much the same way as we would with a permanent tooth — by removing decayed material and filling the prepared space. We can also perform preventive applications like topical fluoride or sealants that strengthen or protect the tooth.
It becomes more complicated, though, if the pulp, the interior of the tooth, becomes decayed. The preferred treatment for this in a permanent adult tooth is a root canal treatment. But with a primary tooth we must also consider the permanent tooth forming below it in the jaw and its proximity to the primary tooth. We need to adapt our treatment for the least likely damage to the permanent tooth.
For example, it may be best to remove as much decayed structure as possible without entering the pulp and then apply an antibacterial agent to the area, a procedure known as an indirect pulp treatment. We might also remove only parts of the pulp, if we determine the rest of the pulp tissue appears healthy. We would then dress the wound and seal the tooth from further infection.
Whatever procedure we use will depend on the extent of decay. As we said before, our number one concern is the permanent tooth beneath the primary. By focusing on the health of both we can help make sure the permanent one comes in the right way.

Keeping your child’s teeth and gums healthy may sometimes seem like “one step forward, two steps back.” You do all the right things like daily brushing and flossing, and keeping sugar consumption to a minimum. But they’re still getting too many cavities.
We can add something else to what you’re already doing to decrease their cavity rate: apply a concentrated fluoride mixture (stronger than what’s found in toothpaste or drinking water) directly to their teeth. Studies have shown that topical fluoride is effective at reducing the risk of new cavities in children at high risk for decay, and may even reverse early decay.
Topical fluoride can be applied as a gel, foam or varnish. The particular method used depends on factors like the child’s age or the preference of the dentist. But any of the three methods can deliver a short-term, high dose of fluoride to the teeth.
As a result, the burst of fluoride strengthens tooth enamel against decay, with plenty of evidence of its effectiveness. As such, the American Dental Association recommends periodic topical fluoride applications for children older than 6, and especially those that appear to be at higher risk for decay.
You might, however, be concerned about the long-term health effects of these stronger concentrations of fluoride. Again, research indicates that the only long-term hazard associated with too much fluoride is a condition called fluorosis, which produces heavy tooth staining. Fluorosis, though, is more of an appearance issue and doesn’t harm the tooth itself. And it can be avoided in the case of topical fluoride by performing the procedure correctly and conservatively.
There’s also a short-term risk of a reaction to the fluoride mixture if the child swallows too much during the procedure, which could cause stomach upset and pain, vomiting or headaches. We can avoid this by using precautions like dental dams and other isolation methods to prevent the child from ingesting it.
Using proper precautions and procedures, topical fluoride is a safe and effective way to give your child added protection against decay. Avoiding this destructive disease can help ensure they’ll enjoy good dental health for the rest of their lives.
