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.

Fans everywhere were recently saddened by the news of musical legend Eddie Van Halen's death. Co-founder and lead guitarist for the iconic rock group Van Halen, the 65-year-old superstar passed away from oral cancer.
Van Halen's rise to worldwide fame began in the 1970s with his unique guitar style and energetic performances, but behind the scenes, he struggled with his health. In 2000, he was successfully treated for tongue cancer. He remained cancer-free until 2018 when he was diagnosed with throat cancer to which he succumbed this past October.
Van Halen claimed the metal guitar picks he habitually held in his mouth caused his tongue cancer. It's more likely, though, that his heavy cigarette smoking and alcohol use had more to do with his cancers.
According to the American Cancer Society, most oral cancer patients are smokers and, as in Van Halen's case, are more likely to beat one form of oral cancer only to have another form arise in another part of the mouth. Add in heavy alcohol consumption, and the combined habits can increase the risk of oral cancer a hundredfold.
But there are ways to reduce that risk by making some important lifestyle changes. Here's how:
Quit tobacco. Giving up tobacco, whether smoked or smokeless, vastly lowers your oral cancer risk. It's not easy to kick the habit solo, but a medically supervised cessation program or support group can help.
Limit alcohol. If you drink heavily, consider giving up alcohol or limiting yourself to just one or two drinks a day. As with tobacco, it can be difficult doing it alone, so speak with a health professional for assistance.
Eat healthy. You can reduce your cancer risk by avoiding processed foods with nitrites or other known carcinogens. Instead, eat fresh fruits and vegetables with antioxidants that fight cancer. A healthy diet also boosts your overall dental and bodily health.
Practice hygiene. Keeping teeth and gums healthy also lowers oral cancer risk. Brush and floss daily to remove dental plaque, the bacterial film on teeth most responsible for dental disease. You should also visit us every six months for more thorough dental cleanings and checkups.
One last thing: Because oral cancer is often diagnosed in its advanced stages, be sure you see us if you notice any persistent sores or other abnormalities on your tongue or the inside of your mouth. An earlier diagnosis of oral cancer can vastly improve the long-term prognosis.
Although not as prevalent as other forms of cancer, oral cancer is among the deadliest with only a 60% five-year survival rate. Making these changes toward a healthier lifestyle can help you avoid this serious disease.

Picture yourself with a beautiful smile…what do you see? Besides straight and uniform teeth framed by the gums, you should also see one other thing indicative of a great smile—your teeth an attractive shade of translucent white.
But as you age your teeth can begin to dull as the enamel loses its translucency and the underlying dentin thickens and yellows. You no longer have the bright smile you once had in younger days.
But if the discoloration is mainly on the outer enamel, teeth whitening could be your answer for regaining your youthful smile. This is a procedure in which we apply a solution containing a bleaching agent (usually hydrogen peroxide) to your teeth. Aided by heat or light to activate it, the solution can temporarily whiten the enamel.
Teeth whitening isn't an exclusive treatment provided by a dentist—there are a number of retail products that enable you to bleach your teeth at home. But there are distinct advantages to having your teeth professionally whitened.
For one, we can control the level of brightness by adjusting the strength of the bleaching solution. This allows you to achieve the kind of look you want—from a more natural and subtler shade to a more dazzling color often called “Hollywood White.”
Any external teeth whitening application will fade with time, regardless of whether they're professional or DIY. But a dental office whitening may last longer due to our stronger solutions and curing techniques. And, by caring for your whitening (by avoiding tobacco and food items that stain teeth) and obtaining occasional touch-ups in our office, the shine could last for a few years.
Again, this particular whitening technique only works with outer staining and yellowing. If your discoloration originates from inside the teeth, you'll need a more invasive method. And your teeth should be reasonably healthy before undergoing whitening.
All in all, though, teeth whitening is an easy and affordable way to brighten your smile. It could help you take years off your appearance.
