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.

Wearing braces can pose challenges for your daily life and habits. One in particular is trying to keep your teeth and gums clean.
Braces or not, your oral hygiene needs to be thorough. Every day, your teeth accumulate a thin film of bacteria and food particles called dental plaque that can cause tooth decay or gum disease. It's essential to remove as much as possible each day by brushing and flossing.
That's a more difficult task with braces. The brackets and wires interfere with accessing many of your teeth's surfaces with a toothbrush or floss. As a result, braces wearers on average have a higher incidence of dental disease than non-wearers.
But while it's difficult to keep your mouth clean wearing braces, it's not impossible. Here are some tips and tools for making oral hygiene easier during orthodontic treatment.
A low-sugar diet. Besides items like chips that could damage your braces, you should also limit your consumption of foods and snacks with added sugar. This carbohydrate is a primary food source for disease-causing bacteria. Limiting sugar in your diet can help reduce plaque buildup.
The right toothbrush. Brushing with braces is easier if you use a soft multi-tufted brush with microfine bristles. The smaller bristles maneuver better around the braces than larger bristled brushes. You'll still need to make multiple passes above and below the wires to be sure you're brushing all tooth surfaces.
Flossing tools. Traditional flossing using just your fingers can be next to impossible to perform with braces. But a tool like a floss holder or threader can make it easier to get between teeth. You might also try a water flosser that removes plaque from between teeth with a pressurized spray of water.
Dental treatments. Your dentist can give your teeth extra protection while you're wearing braces with topically applied fluoride to strengthen enamel. Using mouthrinses with an antibacterial ingredient like chlorhexidine may also reduce harmful bacteria.
Be sure you also keep up regular visits with your family dentist while wearing braces, and especially if you begin to notice puffy and reddened gums or unusual spots on your teeth. The sooner any case of dental disease is detected, the less impact it will have on your dental health.

We're all tempted occasionally to use our teeth in ways that might risk damage. Hopefully, though, you've never considered anything close to what singer, songwriter and now social media persona Jason Derulo recently tried in a TikTok video—attempting to eat corn on the cob spinning on a power drill. The end result seemed to be a couple of broken front teeth, although many of his followers suspected an elaborate prank.
Prank or not, subjecting your teeth to “motorized corn”—or a host of other less extreme actions or habits—is not a good thing, especially if you have veneers, crowns or other dental work. Although teeth can withstand a lot, they're not invincible.
Here, then, are four things you should do to help ensure your teeth stay healthy, functional and intact.
Clean your teeth daily. Strong teeth are healthy teeth, so you want to do all you can to prevent tooth decay or gum disease. Besides semi-annual dental cleanings, the most important thing you can do is to brush and floss your teeth daily. These hygiene tasks help remove dental plaque, a thin biofilm that is the biggest culprit in dental disease that could weaken teeth and make them more susceptible to injury.
Avoid biting on hard objects. Teeth's primary purpose is to break down food for digestion, not to break open nuts or perform similar tasks. You should also avoid habitual chewing on hard objects like pencils, nails or ice to relieve stress. And, you may need to be careful eating apples or other foods with hard surfaces if you have veneers or composite bonding on your teeth.
Wear a sports mouthguard. If you or a family member are regularly involved with sports like basketball, baseball/softball or football (even informally), you can protect your teeth from facial blows by wearing an athletic mouthguard. Although you can obtain a retail variety in most stores selling sporting goods, a custom-made guard by a dentist offers the best protection and comfort.
Visit your dentist regularly. As mentioned before, semi-annual dental cleanings help remove hidden plaque and tartar and further minimize your risk of disease. Regular dental visits also give us a chance to examine your mouth for any signs of decay or gum disease, and to check on your dental health overall. Optimizing your dental health plays a key part in preventing dental damage.
You should expect an unpleasant outcome involving your teeth with power tools. But a lot less could still damage them: To fully protect your dental health, be sure you practice daily oral care, avoid tooth contact with hard objects and wear a mouthguard for high-risk physical activities.

If you suffer frequent sinus infections, you might want to see a dentist. No, really—your recurring sinusitis might stem from a decayed tooth.
Tooth decay can start as a cavity, but left untreated can advance within the tooth and infect the pulp and root canals. If it reaches the end of the root, it can cause the root tip and surrounding bone to break down.
A severe toothache is often a good indicator that you have advanced tooth decay, which can usually be stopped with a root canal treatment. But a decayed tooth doesn't always produce pain or other symptoms—you could have a “silent” infection that's less likely to be detected.
A symptomless, and thus untreated, infection in an upper back tooth could eventually impact the maxillary sinus, a hollow air-filled space located just above your back jaw. This is especially true for people whose tooth roots extend close to or even poke through the sinus floor.
That “silent” infection in your tooth, could therefore become a “loud” one in the sinuses causing chronic post-nasal drip, congestion and, of course, pain. Fortunately, a physician or an ear, nose and throat (ENT) specialist might suspect a dental origin for a case of recurring sinusitis, a condition known as maxillary sinusitis of endodontic origin (MSEO).
Antibiotic treatment can clear up sinusitis symptoms short-term. It's unlikely, though, it will do the same for a dental infection, which may continue to trigger subsequent rounds of sinusitis. The best approach is for a dentist, particularly a specialist in interior tooth disease called an endodontist, to investigate and, if a decayed tooth is found, treat the source of the infection.
As mentioned earlier, the solution is usually a root canal treatment. During this procedure, the dentist completely removes all infected tissue within the pulp and root canals, and then fills the empty spaces to prevent future infection. In one study, root canal therapy had a positive effect on alleviating sinusitis in about half of patients who were diagnosed with a decayed tooth.
If your sinusitis keeps coming back, speak with your doctor about the possibility of a dental cause. You may find treating a subsequently diagnosed decayed tooth could alleviate your sinus problem.

If you live an average lifespan, you'll spend more than 200,000 hours in blissful slumber. It's not a waste, though: You absolutely need this much sleep to maintain optimum physical and mental health. That's why the National Sleep Foundation recognizes each March as Sleep Awareness Month to highlight the obstacles to a good night's sleep. One such obstacle is obstructive sleep apnea (OSA)—and if you have it, we may be able to help you reduce the harm it may be causing you.
OSA is the blockage of the airway during sleep, usually when the tongue relaxes against the back of the throat. As the oxygen level falls, the brain arouses the sleeper to restore airflow. This only takes a few seconds before the person slips back into sleep, but it can occur several times an hour.
As this scenario repeats itself night after night, the person becomes deprived of the deeper stages of sleep they need to stay healthy. The long-term effect can even be life-threatening: Besides chronic fatigue and “brain fog,” there's also an increased risk of high blood pressure, disease or other serious health conditions.
But there are ways to reduce chronic OSA, the most common being a therapy known as continuous positive airway pressure (CPAP). A CPAP machine, prescribed by a medical doctor, consists of a small pump that streams pressurized air into the mouth through a hose and facemask; the increased air pressure in the mouth helps keep the airway open. It's a proven method, but not always a favorite with some patients who find it uncomfortable and restrictive to wear every night.
If you're in that camp regarding CPAP therapy, an alternative may be possible: oral appliance therapy (OAT), which dentists can provide. Worn in the mouth during sleep, this custom-fitted mouthguard-like appliance repositions the tongue so that it doesn't block the airway. There is a variety of mechanisms, but most involve a hinge that positions the lower jaw forward, which in turn pulls the tongue away from the back of the throat.
These less invasive OAT devices may be an alternative to CPAP therapy for people who have mild to moderate OSA and find CPAP machines difficult to use. If you've been diagnosed with OSA and CPAP therapy hasn't been a good fit for you, speak with us about an OAT device. It could help you overcome this common disorder and get the deep sleep you need for a healthy mind and body.
