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.

Rock guitarist Eddie Van Halen died last fall after a long battle with oral cancer, another in a long line of performers, athletes, politicians and other well-known personalities with this serious form of cancer. But household names like Van Halen are just the tip of the iceberg: Around 50,000 Americans are diagnosed with oral cancer each year.
Although not as common as other malignancies (around 2.5% of total cancers), oral cancer has one of the lowest five-year survival rates at a dismal 57%. Part of the reason for this has been the longstanding difficulty detecting it in its earlier stages: Early signs are easy to miss or mistake for a benign sore. As a result, it's often diagnosed after advancing significantly, complicating treatment efforts.
To improve survivability, the Oral Cancer Foundation designates each April as Oral Cancer Awareness Month to better educate people on this deadly disease. Here are 3 things you can do to prevent oral cancer or improve your survival odds if you encounter it.
Know your individual risk factors. Some risk factors for oral cancer are out of your control—for example, your risk may be higher if you're a male over 40, or if you're African-American. But there are also factors you can control like tobacco use, high alcohol consumption or a poor diet, all of which can elevate your cancer risk. You can lower that risk by making lifestyle changes for factors you can control and prioritizing cancer screening if you have factors that you can't.
Pay attention to oral “oddities.” A small mouth sore or patch of odd-looking skin may be nothing—or it may be the beginning of oral cancer. If you do notice something unusual, especially if it seems to linger beyond a couple of weeks, have us examine it as soon as possible. If it does appear suspicious, you may need to undergo a biopsy, a cancer analysis of the suspected tissue. If it is cancerous, an early diagnosis could improve your outcome.
Visit your dentist regularly. There's more to semi-annual dental visits than teeth cleaning. Regular dental visits are an important component in your “early warning system” for oral cancer—we may notice something suspicious during your regular visit, often before you do. If you're older or have other risk factors for oral cancer, we can expand your regular exam to include a comprehensive cancer screening.
Oral cancer is a serious matter. But taking steps to prevent it and staying alert to its warning signs can help you overcome it.
Mike Tyson made a splash when he faced off against sharks during the Discovery Channel's Shark Week 2020. But there's bigger news for fans of the former undisputed world heavyweight champion: After a 15-year absence, he will enter the ring again for two exhibition matches in the Fall. However, it's not just Tyson's boxing action that made news during his 20-year career. His teeth have also gotten their fair share of press.
Tyson used to be known for two distinctive gold-capped teeth in the front left side of his mouth. He made headlines when he lost one of the shiny caps—not from a blow by a fellow pugilist but from being headbutted by his pet tiger as Tyson leaned in for a kiss. Tyson's teeth again garnered attention when he had his recognizable gold caps replaced with tooth-colored restorations. But the world champion may be best known, dentally at least, for his trademark tooth gap, or “diastema” in dentist-speak. Several years ago, he had the gap closed in a dental makeover, but he soon regretted the move. After all, the gap was a signature look for him, so he had it put back in.
That's one thing about cosmetic dentistry: With today's advanced technology and techniques, you can choose a dental makeover to suit your individual taste and personality.
An obvious example is teeth whitening. This common cosmetic treatment is not a one-size-fits-all option. You can choose whether you want eye-catching Hollywood white or a more natural shade.
If your teeth have chips or other small imperfections, bonding may be the solution for you. In dental bonding, tooth-colored material is placed on your tooth in layers and then hardened with a special light. The material is matched to your other teeth so the repaired tooth fits right in. This procedure can usually be done in just one office visit.
For moderate flaws or severe discoloration, porcelain veneers can dramatically improve your appearance. These thin, tooth-colored shells cover the front surface of the tooth—the side that shows when you smile. Veneers are custom-crafted for the ideal individualized look.
Dental crowns can restore single teeth or replace missing teeth as part of a dental bridge. Again, they are manufactured to your specifications. With restorations like crowns and veneers, the smallest detail can be replicated to fit in with your natural teeth—even down to the ridges on the tooth's surface.
And if, like Mike Tyson, you have a gap between your teeth that makes your smile unique, there's no reason to give that up if you opt for a smile makeover. Whether you would like a small cosmetic enhancement or are looking for a more dramatic transformation, we can work with you to devise a treatment plan that is right for you.
