Bright, naturally white teeth are a key component in a beautiful smile. But the opposite is also true: nothing diminishes an otherwise attractive smile more than stained or discolored teeth.
There is good news, however, about tooth staining: it can be greatly reduced with the right whitening technique. But before taking action we need to first uncover the cause for the staining — whether from the outside or inside of the tooth, or a combination of both.
If it’s an external cause — known as extrinsic staining — our diet is usually the source. Foods and beverages that contain tannins, like red wine, coffee or tea fall in this category, as do foods with pigments called carotenes as found in carrots and oranges. Besides limiting consumption of stain-causing foods and maintaining daily oral hygiene, you can also diminish extrinsic staining with a bleaching application.
There are two basic ways to approach this: with either a professional application at our office or with a home kit purchased at a pharmacy or retail store. Although both types use similar chemicals, the professional application is usually stronger and the whitening effect is obtained quicker and may last longer.
Discoloration can also occur within a tooth, known as intrinsic staining, and for various reasons. It can occur during tooth development, as with childhood overexposure to fluoride or from the antibiotic tetracycline. Poor development of enamel or dentin (the main sources of natural tooth color), tooth decay, root canal treatments or trauma are also common causes of intrinsic discoloration.
There are techniques to reduce the effects of intrinsic staining, such as placing a bleaching agent inside the tooth following a root canal treatment. In some cases, the best approach may be to restore the tooth with a crown or porcelain veneer. The latter choice is a thin layer of dental material that is permanently bonded to the outer, visible portion of the tooth: it’s life-like color and appearance covers the discoloration, effectively renewing the person’s smile.

If you’re pregnant, you may find yourself pondering decisions you didn’t have to think about before. Should you have that glass of wine… or skip it, because of the alcohol; go for the sushi… or avoid uncooked foods; take the pain reliever… or live with the headache. And if you have a toothache — or even if you’re overdue for a checkup and a cleaning — you may also be wondering whether having dental treatment (especially treatment that might involve local anesthetics) is safe for you and your developing baby.
Fortunately, a study that recently appeared in the Journal of the American Dental Association (JADA) should let expectant moms breathe a little easier. The research concludes that it’s safe for pregnant women to undergo dental treatment, including procedures that use local anesthetics.
And that’s good news indeed, because while maintaining good oral health during pregnancy is critical for the developing baby, many expectant moms experience problems during this period.Â Some common issues include a higher risk of tooth decay due to increased carbohydrate consumption, and sore or bleeding gums from a condition called pregnancy gingivitis.
According to the study’s lead author, Aharon Hagai, D.M.D., "[Pregnancy] is a crucial period of time in a woman’s life, and maintaining oral health is directly related to good overall health." Yet, as Dr. Hagai notes, pregnant women sometimes avoid the dentist even if they have a problem. So his team set out to determine whether having dental treatment with anesthesia affected the outcome of pregnancies. They compared a total of 1,004 women, some of whom had dental treatment with local anesthesia, and some who did not.
The research showed there was no significant difference between the two groups. This applied in terms of both major medical problems (such as cleft palate, heart defects or cerebral palsy) and other issues, including low birth weight and preterm delivery. Dr. Hagai summed it up this way: "We aimed to determine if there was a significant risk associated with dental treatment with anesthesia and pregnancy outcomes. We did not find any."
So if you’re pregnant, there’s one less thing to worry about. Go ahead and schedule your routine dental check up — and remember that it is particularly important to have cleanings during pregnancy. Â If you experience changes in your oral health, don’t hesitate to come in for an office visit and cleaning; that way, you can make sure your hormonal changes are not playing havoc with your gums. There is an old saying in some cultures that for every child a woman has, she loses a tooth. Don’t let that happen to you.

For lots of sports fans, March is the month to get caught up in basketball “madness.” But many people forget that basketball—whether it's played on a school court or a big-city arena—can be just as dangerous for your teeth as some “full-contact” sports. Just ask Chicago Bulls point guard Kris Dunn. In the last three minutes of the January 17 NBA game between the Bulls and the Golden State Warriors, Dunn stole the ball and went in for the dunk. But the momentum from his fast break left him tumbling head-over-heels, and his face hit the floor.
The game stopped as Dunn was evaluated by medical staff; they found he had dislocated his two front teeth. The next day, the Bulls announced that his teeth had been stabilized and splinted—but Dunn would be out indefinitely because of a concussion.
Teeth that are loosened or displaced are known in dental terminology as luxated. These are fairly common dental injuries in both children and adults—but surprisingly, they don't always produce painful symptoms. Treating luxated teeth generally involves repositioning them and then splinting them in place for stability. Depending on the severity of the injury, the outlook for splinted teeth can be quite favorable. However, it may involve several treatments over a period of time—for example, a root canal if the tooth's inner pulp has been damaged, and possibly additional restorative or cosmetic work.
If the injured teeth can't be saved, they can usually be replaced by dental implants or a bridge. Bridges rely on adjacent teeth (also called abutment teeth) for their support. These teeth must be prepared (reduced in size) to accommodate the dental crowns that will hold the bridge in place, as well as the ones that will replace the missing tooth or teeth. Dental implants, today's gold standard of tooth replacement, are supported by root-like inserts made of titanium that are set directly into the jawbone. These dental implants support lifelike crowns that look and feel like natural teeth, and can last for years with routine care.
Better still, many dental injuries can be prevented by wearing a protective mouthguard. We can provide a custom-fabricated mouthguard, made from an exact model of your bite, which offers the maximum in comfort and protection. This is a vital piece of safety equipment that should be part of every sports enthusiast's gear.
With good dental care, it's a sure bet that Kris Dunn will be smiling when he returns to the court. We wish him a speedy recovery.
