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.

Although dental care is our primary focus, we dentists are also on the lookout for other health problems that may manifest in the mouth. That's why we're sometimes the first to suspect a patient may have an eating disorder.
Eating disorders are abnormal dietary patterns that can arise from mental or emotional issues, the most common being anorexia nervosa and bulimia nervosa. Each has different behaviors: Anorexics abnormally restrict their food intake (“self-starvation”), while bulimics typically eat heavily and then induce vomiting (“binge and purge”).
Although bulimics are more likely to binge and purge, anorexics may also induce vomiting. That practice in particular can leave a clue for dentists. While vomiting, powerful stomach acid enters the mouth, which can then soften and erode tooth enamel.
It's the pattern of erosion a dentist may notice more than the erosion itself that may indicate an eating disorder. A person while vomiting normally places their tongue against the back of the lower teeth, which somewhat shields them from acid. The more exposed upper teeth will thus tend to show more erosion than the bottom teeth.
A dentist may also notice other signs of an eating disorder. Enlarged salivary glands or a reddened throat and tongue could indicate the use of fingers or objects to induce vomiting. Lack of oral hygiene can be a sign of anorexia, while signs of over-aggressive brushing or flossing may hint of bulimia.
For the sake of the person's overall well-being, the eating disorder should be addressed through professional counseling and therapy. An excellent starting point is the website nationaleatingdisorders.org, sponsored by the National Eating Disorders Association.
The therapy process can be lengthy, so patients should also take steps to protect their teeth in the interim. One important measure is to rinse out the mouth following purging with a little baking soda mixed with water. This will help neutralize oral acid and reduces the risk of erosion. Proper brushing and flossing and regular dental visits can also help prevent dental disease.
An eating disorder can be traumatic for both patients and their families, and can take time to overcome. Even so, patients can reduce its effect on their dental health.

Actor Zac Efron has one of the top smiles in a business known for beautiful smiles. Bursting on the scene in 2006 at age 18 in High School Musical, Efron has steadily increased his range of acting roles. He recently starred as Ted Bundy on Netflix, wearing prosthetics to match the notorious serial killer's crooked teeth.
With his growing fame, Efron's attractive smile has become one of his more memorable attributes. But it wasn't always so. Before Hollywood, Efron's smile was less than perfect with small, uneven teeth and a gap between his top front teeth. Before and after pictures, though, make it quite apparent that the actor has undergone a significant smile makeover.
While fans are abuzz on the 411 regarding his dental work, Efron himself has been hush-hush about his smile transformation. We won't join the speculation: Instead, here are a few possible ways you can get a more attractive smile like Zac Efron.
Teeth whitening. A single-visit, non-invasive teeth whitening procedure can transform your dull, stained teeth into a brighter, more attractive smile. Although the effect isn't permanent, it could last a few years with a professional whitening and good oral practices. Having it done professionally also gives you more control over the level of shading you prefer—from soft natural white to dazzling Hollywood bright.
Orthodontics. Like Efron, if your teeth aren't quite in proper alignment, straightening them can make a big difference in your appearance (and your oral health as well). Braces are the tried and true method for moving teeth, but you may also be able to choose clear aligner trays, which are much less noticeable than braces. And don't worry about your age: Anyone with reasonably good dental health can undergo orthodontics.
Bonding. We may be able to correct chips and other slight tooth flaws with durable composite resins. After preparing your tooth and matching the material to your particular color, we apply it directly to your tooth in successive layers. After hardening, the unsightly defect is no more—and your smile is more attractive.
Veneers. Dental veneers are the next step up for more advanced defects. We bond these thin, custom-made layers of dental porcelain to the front of teeth to mask chips, heavy staining and slight tooth gaps. Although we often need to permanently remove a small amount of tooth enamel, veneers are still less invasive than some other restorations. And your before and after could be just as amazing as Zac Efron's.
Improving one's smile isn't reserved for stars like Zac Efron. There are ways to correct just about any dental defect, many of which don't require an A-lister's bank account. With a little dental “magic,” you could transform your smile.
