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.

Like other healthcare providers, your dentist keeps records of your ongoing care. These include not only their written notes but also x-ray imaging, frequency of visits and cleanings, and any medical information that could affect your care. What’s more, they have a legal obligation to maintain these records.
Your dental records help guide decisions about your care. In that regard, you should consider something else—you may need to change providers: your dentist retires or you move; your dentist isn’t in your new insurance network; or, unfortunately, you have an “irreconcilable” difference with your provider.
If that happens, it’s very important your dental records find their way to your new provider. Here are 3 reasons why.
Your individual dental history. Each person’s dental situation and needs are unique. Your past records help clue in your new dentist about your past history and current needs, which will help guide how they treat you.
Time and money. Your dental records contain x-rays or other diagnostic information about your oral condition, including preparations for any upcoming dental work. If you change dentists before completing that treatment, your new dentist may have to start over with new diagnostic tests if they don’t have this previous data. It could cost you more money and make you wait longer for a needed procedure.
Coordinating dental care with your general health. Your mouth isn’t isolated from the rest of your body, and some dental treatment measures could affect other health conditions (and vice-versa). If your new dentist knows other health issues you may have from your previous records, it can help ensure you’re getting dental treatment appropriate to your overall health.
For the most streamlined transition between providers, it’s important your dental records follow you. You’re entitled to having those records transferred, and, if you’re uncomfortable asking yourself, your new provider can obtain them for you. Just be sure to ask.

Some moviegoers have been known to crunch popcorn, bite their fingers or grab their neighbor’s hands during the intense scenes of a thriller. But for one fan, the on-screen action in the new superhero film Black Panther led to a different reaction.
Sophia Robb, an 18-year-old Californian, had to make an emergency visit to the orthodontic office because she snapped the steel wire on her retainer while watching a battle scene featuring her Hollywood crush, Michael B. Jordan. Her jaw-clenching mishap went viral and even prompted an unexpected reply from the actor himself!
Meanwhile, Sophia got her retainer fixed pronto—which was exactly the right thing to do. The retention phase is a very important part of orthodontic treatment: If you don’t wear a retainer, the beautiful new smile you’re enjoying could become crooked again. That’s because if the teeth are not held in their new positions, they will naturally begin to drift back into their former locations—and you may have to start treatment all over again…
While it’s much more common to lose a removable retainer than to damage one, it is possible for even sturdy retainers to wear out or break. This includes traditional plastic-and-wire types (also called Hawley retainers), clear plastic retainers that are molded to fit your teeth (sometimes called Essix retainers), and bonded retainers: the kind that consists of a wire that’s permanently attached to the back side of your teeth. So whichever kind you use, do what Sophia did if you feel that anything is amiss—have it looked at right away!
When Black Panther co-star Michael B. Jordan heard about the retainer mishap, he sent a message to the teen: “Since I feel partly responsible for breaking your retainers let me know if I can replace them.” His young fan was grateful for the offer—but even more thrilled to have a celebrity twitter follower.
If you have questions about orthodontic retainers, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Importance of Orthodontic Retainers” and “Bonded Retainers.”
There are plenty of options today for replacing missing teeth, including dental implants. But if the teeth have been missing for some time, complications can arise that limit your restorative options.
The most consequential possibility is bone loss. Bone has a life cycle: old cells dissolve (resorb), and are then replaced by new cells, stimulated to grow by the forces applied to the teeth during chewing. But the bone won't receive this stimulation if a tooth is missing — so growth slows down, which causes the bone volume to diminish with time.
Another complication can occur involving other teeth around the open space. These teeth will naturally move or “drift” out of their normal position into the missing tooth space. As a result we may not have enough room to place a prosthetic (false) tooth.
If either or both of these complications occur, we'll need to address them before attempting a restoration. Bone loss itself could eliminate dental implants as an option because they require a certain amount of supporting bone for correct placement. Bone loss could also make correcting misaligned teeth difficult if not impossible.
It might be possible, though, to regenerate lost bone with a bone graft. The graft is placed, sometimes along with growth stimulating substances, within the diminished bone area. It then serves as a scaffold upon which new bone can form.
If the bone becomes healthy again, we can then attempt to move any drifted teeth back to where they belong. Besides braces, there's another treatment option especially popular with adults: clear aligners. These are a series of removable, clear plastic trays that, like braces, exert gradual pressure on the teeth to move them. Patients wear each individual tray for about two weeks, and then switch to the next tray in the series to continue the process.
Unlike their traditional counterparts, clear aligners can be removed for cleaning or for special occasions. More importantly, they're much less noticeable than traditional braces.
Once any problems with bone health or bite have been addressed and corrected, you'll have a fuller range of options for replacing your missing teeth. With a little extra time and effort, you'll soon be able to regain a smile you'll be proud to display.
What's your favorite winter sport? For some, it's all about swooshing down a snowy trail on skis, a board, or a sled. For others, the main attraction is skating at an ice rink or a frozen pond. If you're more of an indoors athlete, you may enjoy a fast-moving game of basketball or a round of squash. Or, you might take a turn on a climbing wall or a trampoline.
What do all these activities have in common? They're fun, they're great exercise…and they all come with a risk of injury to your teeth.
It's easy to see how a collision on snow or ice could result in a blow to the mouth. But did you know that basketball (along with hockey) is among the sports with the highest risk of facial injury? What's more, many "non-contact" sports actually have a similar risk.
Located front and center in the face, the incisors (front teeth) are the ones most likely to sustain injury. Unfortunately, they are also the most visible teeth in your smile. With all of the advances in modern dentistry, it's possible to restore or replace damaged teeth in almost any situation—but the cost can be high, both for present restoration and future preservation. Is there a better alternative?
Yes! It isn't sitting at home—it's wearing a custom-made mouthguard when there's a risk of facial injury.
Most people don't ski or play hockey without protective gear like a helmet. A mouthguard can effectively protect against dental injury that might otherwise be serious. Available here at the dental office, a custom mouthguard is made from an exact model of your own teeth, so it's comfortable to wear and fits perfectly—but no safety equipment can work if you don't use it!
So whether you like to hit the trails or the gym this winter, don't forget to bring a custom-made mouthguard. It's a small piece of gear that can save you from a big headache!
