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.

If you have periodontal (gum) disease, you probably already know you’re in danger of eventual tooth and bone loss if the infection isn’t brought under control. But if you also have diabetes, the effects from gum disease could extend well beyond your mouth.
Gum disease is a bacterial infection caused by plaque, a film of food remnant that builds up on tooth surfaces mainly due to poor oral hygiene. As the infection grows, your body’s immune system responds by flooding your gum tissues with antibodies to fight it, resulting in inflammation. As the inflammation persists, though, it damages the gum and underlying bone tissue, which in turn leads to gum and bone loss from the teeth.
Diabetes also causes an inflammatory response within the body. The disease develops either as a result of the body’s decreased ability to produce insulin to balance the glucose (sugar) levels in the bloodstream (Type 1) or the body develops a resistance to insulin’s effects (Type 2). As a result diabetics experience abnormally high blood glucose levels, a condition called hyperglycemia. This triggers chronic inflammation that can lead to inhibited wound healing, increased risk of heart, kidney or eye disease, coma or death.
Gum disease can worsen diabetic inflammation, and vice versa. The effects of the oral infection add to the body’s already overloaded response to diabetes. In turn, the immune system is already compromised due to diabetes, which can then increase the severity of the gum disease.
Research and experience, though, have found that pursuing treatment and disease management for either condition has a positive effect on managing the other. Treating gum disease through plaque removal, antibiotic therapy, surgery (if needed) and renewed oral hygiene will diminish the oral infection and reduce the body’s immune response. Caring for diabetes through medication, diet, exercise and lifestyle changes like quitting smoking will in turn contribute to a quicker healing process for infected gum tissues.
Treating gum disease when you have diabetes calls for a coordinated approach on both fronts. By caring for both conditions you’ll have a more positive effect on your overall health.
During your lifetime you’ll eat thousands of meals — and generate a lot of force from chewing over the years. But thanks to a support system of gum tissues and bone, your teeth can normally handle it.
What your teeth can’t handle, though, are higher than normal chewing forces on a continual basis. This can happen if you grind your teeth, which can produce 20-30 times the normal force. The habit often arises in adults because of high stress and often occurs during sleep.
These abnormal forces can stretch the periodontal ligaments that hold teeth in place, cause the teeth to become loose and at increased risk for loss. The best treatment strategy is to reduce clenching with, for example, muscle relaxants or anti-inflammatory drugs or lower the effects with a mouth guard that won’t allow the teeth to make solid contact during clenching.
Your teeth can also become loose even with normal chewing forces if you have advanced periodontal (gum) disease. Gum disease arises from dental plaque, a thin film of bacteria and food particles left on teeth due to poor oral hygiene. As it builds up, it causes inflammation of the gum tissues resulting in bone loss and causing the gums to detach from the teeth, increasing pocket depth.
Our first step in this case is to treat the gum disease by removing plaque and calculus (tartar) from all tooth and gum surfaces. This includes infected areas below the gum line and around the roots, a circumstance that could require surgical access.
As treatment progresses in either of these scenarios the gum tissues heal and often regain their attachment to the teeth. But that can take time, so we may need to stabilize any loose teeth in the short term. The most common way is to splint them to other secure teeth. This is done by using a clear acrylic bonding material to join the loose teeth together with a strip of metal or other rigid material (like joining pickets in a fence).
When symptoms arise, quick action is the key to preventing lost teeth. If you notice swollen, painful or bleeding gums or especially loose teeth, don’t delay — contact us so we can begin treatment as soon as possible.

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment. You can read more about bruxism in the Dear Doctor magazine article “Stress and Tooth Habits.”
Eaten in a fast food restaurant lately? If so, maybe you’ve noticed some changes in the big, colorful signs behind the counters. Many have begun promoting a few “healthier” selections (like salads and grilled items) and giving a more extensive listing of nutritional information. But there’s one thing you might not have noticed on those displays: a listing for soda among the beverage choices in the kiddie meal packages. That’s because they are no longer there.
Recently, Burger King quietly removed sugary fountain drinks from the in-store and online menu boards that show what you get with kids’ meals. They were following the lead of McDonalds and Wendy’s, both of which made similar moves in prior months. You can still get a soda with your kiddie burger if you specifically ask for one, but we’re hoping you won’t; here’s why.
For one thing, youth obesity has nearly tripled in the past three decades. As the U.S. Centers for Disease Control and Prevention (CDC) has noted, it’s now an epidemic affecting more than one in six children and adolescents. Many of the extra calories kids get are blamed on sugary drinks: According to a study by the Harvard School of Public Health, children’s daily calorie intake from these beverages rose by 60 percent in recent years. Obesity makes kids more likely to get many diseases, and can lead to problems in psychological and social adjustment.
But that’s not all. As dentists, we’re concerned about the potential for soda to cause tooth decay, which is still the number one chronic disease in children around the world. The association between sugary drinks and cavities is clear. So is the fact that tooth decay causes pain, countless hours of missed school and work, and expense that’s largely unnecessary, because it’s a disease that is almost 100 percent preventable.
While the new signage at fast food restaurants won’t make soda disappear, it does tend to make it less of an automatic choice. Anything that discourages children from routinely consuming soda is bound to help — and let’s point out that the same thing goes for other sweet and acidic beverages including so-called “sports” and “energy” drinks. It’s best to try and eliminate these from your child’s diet; but if you do allow them, at least limit them to mealtimes, and give your mouth a break from sweets between meals. That gives the saliva enough time to do its work as a natural buffer and acid-neutralizer.
What else can you do to help keep your child’s oral hygiene in tip-top shape? Be sure they brush their teeth twice and floss once every day, and bring them in for regular checkups and cleanings. But if you do suspect tooth decay, don’t delay treatment: Left alone, decay bacteria can infect the inner pulp of the tooth, resulting in severe pain, inflammation, and possibly the need for root canal treatment.
