For decades, dental x-rays have helped us accurately diagnose and treat a wide array of dental diseases and conditions. But even with recent advances in digital imaging, the traditional x-ray does have one drawback: its two-dimensional view doesn’t always provide the “big picture” that a three-dimensional viewpoint can provide.
But a new type of x-ray technology can do just that: known as cone beam computed tomography (CBCT), these machines record hundreds of digital images as a cone-shaped beam of x-ray energy is projected through a device that rotates around a person’s head. A computer then assembles the images into a single three-dimensional image that can be manipulated on screen to view from various angles. Not only does this provide greater context and detail, it does so with no more radiation exposure than a standard 20-film digital full-mouth x-ray series.
While CBCT hasn’t replaced the traditional x-ray, it’s making its mark in a number of specialized areas of dentistry. The following are just a few of the ways CBCT is improving both accuracy and treatment outcomes.
Orthodontics. CBCT can provide a much more detailed view of the entire jaw; this can help us determine the best locations for realigning teeth safely and effectively.
Dental Implants. With a CBCT scan we can precisely locate nerve canals, sinuses and adjacent teeth before implant surgery to locate the best position for the implant.
TMD Treatment. To help develop the best treatment approach for alleviating the pain and dysfunction of temporo-mandibular joint disease (TMD), a CBCT scan can provide us detailed information on how the disease is affecting a patient’s joints, teeth, sinuses and airway.
Impactions. An impacted tooth can exert damaging pressure against the roots of neighboring teeth. A CBCT scan allows us to observe the impacted tooth from various vantage points to determine the best treatment approach for neighboring teeth, nerve canals and sinuses.

While she was pregnant with her son Camden Jack Cutler, 25-year-old Kristin Cavallari noticed an odd occurrence in her bathroom sink: “Every time I floss, my sink looks like I murdered somebody!” the actress and reality-TV personality exclaimed. Should we be concerned that something wicked is going on with the star of Laguna Beach and The Hills?
Before you call in the authorities, ask a periodontist: He or she will tell you that there's actually no mystery here. What Cavallari noticed is, in fact, a fairly common symptom of “pregnancy gingivitis,” a condition that affects many expectant moms in the second to eighth month of pregnancy. But why does it occur at this time?
First — just the facts: You may already know that gingivitis is the medical name for an early stage of gum disease. Its symptoms may include bad breath, bleeding gums, and soreness, redness, or tenderness of the gum tissue. Fundamentally, gum disease is caused by the buildup of harmful bacteria, or plaque, on the teeth at the gum line — but it's important to remember that, while hundreds of types of bacteria live in the mouth, only a few are harmful. A change in the environment inside the mouth — like inadequate oral hygiene, to use one example — can cause the harmful types to flourish.
But in this case, the culprit isn't necessarily poor hygiene — instead, blame it on the natural hormonal changes that take place in expectant moms. As levels of some female hormones (estrogen and/or progesterone) rise during pregnancy, changes occur in the blood vessels in the gums, which cause them to be more susceptible to the effects of bacterial toxins. The bacteria produce toxic chemicals, which in turn bring on the symptoms of gingivitis — including painful and inflamed gums that may bleed heavily when flossed.
Is pregnancy gingivits a cause for concern? Perhaps — but the condition is generally quite treatable. If you've noticed symptoms like Kristen's, the first thing you should do it consult our office. We can advise you on a variety of treatments designed to relieve the inflammation in your gums and prevent the harmful bacteria from proliferating. Of course, your oral health (and your overall health) are prime concerns during pregnancy — so don't hesitate to seek medical help if it's needed!
How did things work out with Kristen? She maintained an effective oral hygiene routine, delivered a healthy baby — and recently appeared on the cover of Dear Doctor magazine, as the winner of the “Best Celebrity Smile” contest for 2012. And looking at her smile, it's no mystery why she won.

Each part of the human body is an intricate wonder. Take your teeth, for example: they’re so woven into everyday life we don’t notice them, yet they each work seamlessly with the jaws and mouth so we can eat, speak and even smile.
Here, then, are a few facts to help you understand — and appreciate — these tiny, amazing wonders we call teeth.
Layer Upon Layer. Rather than one solid mass, teeth are composed of different layers of slightly different tissues each with a unique role in protecting and enabling a tooth to function. Innermost is the pulp filled with connective tissue encasing blood vessels and nerves that transmit sensations to the brain. The next layer out is the dentin, a bone-like material sensitive to touch and other stimuli, which also absorbs some of the forces generated when biting or chewing. The outermost layer is enamel, the hardest material in the body and the tooth’s first defense against infection and other dangers.
Front and Center. Teeth perform different functions depending on their type and location. Front teeth are our “onstage performers” — they help us to speak and enunciate words clearly and, of course, contribute to our smile. They’re also adept at cutting through food when it first enters our mouths.
The Support Team. In keeping with our theater analogy, back teeth are our “backstage crew”: they help support our facial height, provide balance for the jaws as we swallow and protect the front teeth from too much vertical force. They’re also able to crush food before we finally swallow, which aids in the digestive process.
Intended for a Lifetime. If you consider all the environmental factors our teeth face — acidic foods, biting forces and temperature swings to name a few — you then can appreciate their resiliency. Of course, teeth have their enemies: decay, infection and trauma. With daily brushing and flossing and at least a couple of visits a year to our office for cleanings and checkups, you can help thwart many of those enemies. With both our efforts we can make sure your teeth really do last a lifetime.
