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.

Lately, you’ve noticed your young child’s primary teeth don’t appear to be coming in straight. Is it a problem?
The answer to that question is best answered by an early orthodontic evaluation performed by an orthodontist. It’s advisable for a child as young as 7 to undergo such an exam.
While a child’s primary teeth have a short life span of a few years, that doesn’t make them less important than the permanent teeth that replace them. In fact, they’re extremely influential for permanent tooth development — each one serves as a guide for its replacement to erupt in a proper position. A future malocclusion (bad bite) that becomes more apparent later in life would have been well underway years before.
Orthodontists have the training and expertise to spot these emerging problems in their early stages. Early detection can reduce the extent — and costliness — of future orthodontic treatment by introducing preventative or interceptive measures — even while there’s still a mix of primary and permanent teeth in the mouth. For example, a child wearing a simple type of retainer that influences the development of the bite could minimize or even correct a growing malocclusion.
You can also take advantage of opportunities to discover potential orthodontic problems early through a general or pediatric dentist. By having regular dental cleanings and checkups, the dentist might observe early bite development that should be reviewed by an orthodontist. If not, it’s still a good idea to undergo an orthodontic evaluation no later than age 7.
Given the stage of jaw and facial structure development, waiting until puberty to focus on orthodontic problems may be too late for some problems — and much more expensive than if caught and treated earlier. Getting ahead of these issues earlier in your child’s dental development will help ensure they’ll have a healthy bite throughout their life.

After ruling out other causes for your jaw pain, your doctor or dentist has made a diagnosis: a temporomandibular joint disorder (TMD). With TMD, your pain symptoms and other dysfunctions are due to a problem associated with the temporomandibular joint (TMJ) that connects your lower jaw (mandible) to your upper skull (cranium).
There are a number of treatment options, but most can be classified as either aggressive or conservative. Aggressive treatments are more interventional and target problems with the teeth such as bite problems or jaw relationships as they relate to the bite, which are thought to be underlying causes for TMD. Such treatments include orthodontics to realign teeth, crown or bridgework, or surgical treatment to the jaw or joint itself. These treatments are controversial and irreversible — with no guarantee of symptom relief.
It’s thought by many to be appropriate, then, to start with more conservative treatments. Many of these are based on treating the TMJ — which is a joint, a moveable bony structure connected by muscles and tendons — with an orthopedic approach, using treatments similar to those used for other joint problems.
Here, then, are some of those conservative therapies that may relieve your TMD pain and other symptoms.
Physical Therapy. Commonly used to treat pain and dysfunction in other joints, physical therapies like manual manipulation, massage, alternating hot and cold packs or exercises can be used to relax, stretch or retrain the muscles that operate the TMJ while reducing pain and inflammation.
Medications. Medications may be incorporated into the treatment plan to relieve pain, reduce inflammation or relax tense muscles. Besides prescription drugs, over-the-counter anti-inflammatory drugs (such as ibuprofen or acetaminophen) are also commonly used.
Bite Appliances. If night-time teeth grinding or clenching habits are a primary cause for the TMD, you may benefit from wearing an occlusal bite guard while you sleep, designed to specifically fit your upper teeth. Because the lower teeth can’t grip the guard’s smooth plastic surface when biting down, they’ll more likely produce less force. This gives the jaw muscles a chance to relax during sleep.
Diet changes. Changing to softer foods, which don’t require strenuous chewing, and eliminating the chewing gum habit will further help reduce stress on the TMJs and also give your muscles a chance to relax and heal.

She's an international star who's recognized everywhere she goes. As Carol Brady, she was an ambassador for the “blended family” before most of us even knew what to call her bunch. And her TV Land Pop Culture Icon Award is on permanent display in the National Museum of American History. So what item that fits inside a purse can't Florence Henderson do without?
“I will never leave home without dental floss!” she recently told an interviewer with Dear Doctor magazine. “Because I have such a wide smile, I have found spinach or black pepper between my teeth after smiling very broadly and confidently.”
Henderson clearly understands the importance of good oral hygiene — and she's still got her own teeth to back it up! In fact, flossing is the best method for removing plaque from between the teeth, especially in the areas where a brush won't reach. Yet, while most people brush their teeth regularly, far fewer take the time to floss. Is there any way to make flossing easier? Here are a couple of tips:
Many people have a tendency to tighten their cheeks when they're holding the floss, which makes it more difficult to get their fingers into their mouths and working effectively. If you can relax your facial muscles while you're flossing, you'll have an easier time.
To help manipulate the floss more comfortably, try the “ring of floss” method: Securely tie the floss in a circle big enough to easily accommodate the fingers of one hand. To clean the upper teeth, place fingers inside the loop, and let the thumb and index finger guide the floss around each tooth. For the lower teeth, use two index fingers. Keep moving the floss in your hand so you always have a clean edge... and remember, the goal is to get the tooth clean, but it shouldn't hurt — so don't use too much pressure or go too fast.
So take a tip from Mrs. Brady: Don't forget the floss! If you would like more information about flossing and other oral hygiene techniques, please contact us for a consultation. You can learn more in the Dear Doctor magazine article “Flossing: A Different Approach.”
