Tara Lipinski loves to smile. And for good reason: The Olympic-gold medalist has enjoyed a spectacular career in ladies' figure skating. Besides also winning gold in the U.S. Nationals and the Grand Prix Final, in 1997 Lipinski became the youngest skater ever to win a World Figure Skating title. Now a sports commentator and television producer, Lipinski still loves to show her smile—and counts it as one of her most important assets. She also knows the importance of protecting her smile with daily hygiene habits and regular dental care.
Our teeth endure a lot over our lifetime. Tough as they are, though, they're still vulnerable to disease, trauma and the effects of aging. To protect them, it's essential that we brush and floss every day to remove bacterial plaque—that thin accumulating film on teeth most responsible for tooth decay and gum disease.
To keep her smile in top shape and reduce her chances of dental disease, Lipinski flosses and brushes daily, the latter at least twice a day. She also uses a tongue scraper, a small handheld device about the size of a toothbrush, to remove odor-causing bacteria and debris from the tongue.
Lipinski is also diligent about visiting the dentist for professional cleanings and checkups at least twice a year because even a dedicated brusher and flosser like her can still miss dental plaque that can then harden into tartar. Dental hygienists have the training and tools to clear away any lingering plaque and tartar that could increase your disease risk. It's also a good time for the dentist to check your teeth and gums for any developing problems.
The high pressure world of competitive figure skating and now her media career may also have contributed to another threat to Lipinski's smile: a teeth-grinding habit. Teeth grinding is the unconscious action—often while asleep—of clenching the jaws together and producing abnormally high biting forces. Often a result of chronic stress, teeth grinding can accelerate tooth wear and damage the gum ligaments attached to teeth. To help minimize these effects, Lipinski's dentist created a custom mouthguard to wear at night. The slick plastic surface of the guard prevents the teeth from generating any damaging biting forces when they clench together.
The importance of an attractive smile isn't unique to celebrities and media stars like Tara Lipinski. A great smile breeds confidence for anyone—and it can enhance your career, family and social relationships. Protect this invaluable asset with daily oral hygiene, regular dental visits and prompt treatment for disease or trauma.
The mouth is a crowded place with nerves, blood vessels and sinus cavities sharing common space with the teeth and gums. Although important in their own right, these structures can also hinder treatment for complex dental situations like dental implant surgery or impacted teeth.
Treating these and similar situations depends on getting an accurate depiction of “what lies beneath.” Conventional x-rays help, but their two-dimensional images don't always give the full picture. There's another way—cone beam computed tomography (CBCT).
Similar to CT scanning, CBCT uses x-ray energy to take hundreds of “sliced” images that are then re-assembled with special software to create a three-dimensional model viewable on a computer screen. CBCT is different, though, in that it employs a scanning device that revolves around a patient's head, which emits a cone-shaped beam of x-rays to capture the images.
A dentist can manipulate the resulting 3-D model on screen to study revealed oral structures from various angles to pinpoint potential obstacles like nerves or blood vessels. The detailed model may also aid in uncovering the underlying causes of a jaw joint disorder or sleep apnea.
CT technology isn't the only advanced imaging system used in healthcare. Another is magnetic resonance imaging (MRI), which excites hydrogen atoms in water molecules. This produces different vibration rates in individual tissue structures, which are then translated into detailed images of these structures. Unlike CT or CBCT, MRI doesn't use x-ray energy, but rather a magnetic field and radio waves to produce the atomic vibrations.
But while providing good detail of soft tissues, MRI imaging doesn't perform as well as CBCT with harder tissues like bone or teeth. As to the potential risks of CBCT involving x-ray radiation exposure, dentists follow much the same safety protocols as they do with conventional x-rays. As such, they utilize CBCT only when the benefits far outweigh the potential x-ray exposure risks.
And, CBCT won't be replacing conventional x-rays any time soon—the older technology is often the more practical diagnostic tool for less invasive dental situations. But when a situation requires the most detailed and comprehensive image possible, CBCT can make a big difference.

Teenagers can have the same smile-disrupting tooth flaws as adults. But not all cosmetic treatments available to adults are appropriate for teenagers—at least not until they get a little older. Dental veneers fall into that category.
A veneer is a thin porcelain shell custom-made by a dental lab, and bonded by a dentist to the face of a tooth to mask chips, stains, gaps or other imperfections. Because they're less invasive than other measures, veneers are highly popular as a cosmetic dental solution. They do, however, usually require some enamel removal so that they'll appear more natural.
This enamel removal typically won't impact an adult tooth other than it permanently requires it to have veneers or other restorations after alteration. But there is a risk of damage to a teenager's tooth, which hasn't fully developed.
Adolescent teeth usually have a larger pulp chamber (filled with an intricate network of nerves and blood vessels) than adult teeth. And because the enamel and dentin layers may not yet be fully developed, the pulp is much nearer to the tooth's surface.
We must be very careful then in removing enamel and dentin for veneers or we may penetrate the pulp and risk damaging it. Alternatively, there is the possibility of no-prep veneers which are very conservative but often are unable to be done because of the need to often remove tooth structure to make the veneers look natural.
Another cosmetic problem can occur if we place veneers on a patient's teeth whose jaws and mouth structures are still growing. Eventually, the gums could recede and an unsightly gap form between the veneer and the adjacent natural tooth.
Fortunately, there are other techniques we can use to improve a tooth's appearance. Mild chipping can be repaired by bonding composite resin material to the tooth. Some forms of staining may be overcome with teeth whitening. These and other methods can address a teenager's smile appearance until their teeth are mature enough for veneers.
Whether or not a tooth is ready for veneers will depend on its level of development, something that can often be ascertained with x-rays or other diagnostic methods. And if a tooth has already undergone a root canal treatment, there isn't as much concern. In the meantime, though, it may be better for your teen to wait on veneers and try other techniques to enhance their smile.
