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.

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.

It often begins without you realizing it—spreading ever deeper into the gums and damaging tissue attachments, teeth and supporting bone in its way. In the end, it could cause you to lose your teeth.
This is periodontal (gum) disease, a bacterial infection caused by dental plaque, a thin biofilm that accumulates on tooth surfaces. It in turn triggers chronic inflammation, which can cause the gum attachments to teeth to weaken. Detaching gum ligaments may then produce diseased voids—periodontal pockets—that can widen the gap between the teeth and the gums down to the roots.
There is one primary treatment objective for gum disease: uncover and remove any and all plaque and tartar (hardened plaque). If the infection has advanced no further than surface gum tissues, it may simply be a matter of removing plaque at or just below the gum line with hand instruments called scalers or ultrasonic equipment.
The disease, however, is often discovered in more advanced stages: The initial signs of swollen, reddened or bleeding gums might have been ignored or simply didn't appear. Even so, the objective of plaque and tartar removal remains the same, albeit the procedures may be more invasive.
For example, we may need to surgically access areas deep below the gum line. This involves a procedure called flap surgery, which creates an opening in the gum tissues resembling the flap of an envelope. Once the root or bone is exposed, we can then remove any plaque and/or tartar deposits and perform other actions to boost healing.
Antibiotics or other antibacterial substances might also be needed for stopping an infection in advanced stages. Some like the antibiotic tetracycline can be applied topically to the affected areas to directly stop inflammation and infection; others like mouthrinses with chlorhexidine might be used to fight bacteria for an extended period.
Although effective, treatment for advanced gum disease may need to continue indefinitely. The better approach is to focus on preventing a gum infection through daily brushing and flossing and regular dental cleanings. And at the first sign of problems with your teeth and gums, see us as soon as possible—the earlier in the disease progression that we can begin treatment, the better the outcome.
