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.

Although dental care is our primary focus, we dentists are also on the lookout for other health problems that may manifest in the mouth. That's why we're sometimes the first to suspect a patient may have an eating disorder.
Eating disorders are abnormal dietary patterns that can arise from mental or emotional issues, the most common being anorexia nervosa and bulimia nervosa. Each has different behaviors: Anorexics abnormally restrict their food intake (“self-starvation”), while bulimics typically eat heavily and then induce vomiting (“binge and purge”).
Although bulimics are more likely to binge and purge, anorexics may also induce vomiting. That practice in particular can leave a clue for dentists. While vomiting, powerful stomach acid enters the mouth, which can then soften and erode tooth enamel.
It's the pattern of erosion a dentist may notice more than the erosion itself that may indicate an eating disorder. A person while vomiting normally places their tongue against the back of the lower teeth, which somewhat shields them from acid. The more exposed upper teeth will thus tend to show more erosion than the bottom teeth.
A dentist may also notice other signs of an eating disorder. Enlarged salivary glands or a reddened throat and tongue could indicate the use of fingers or objects to induce vomiting. Lack of oral hygiene can be a sign of anorexia, while signs of over-aggressive brushing or flossing may hint of bulimia.
For the sake of the person's overall well-being, the eating disorder should be addressed through professional counseling and therapy. An excellent starting point is the website nationaleatingdisorders.org, sponsored by the National Eating Disorders Association.
The therapy process can be lengthy, so patients should also take steps to protect their teeth in the interim. One important measure is to rinse out the mouth following purging with a little baking soda mixed with water. This will help neutralize oral acid and reduces the risk of erosion. Proper brushing and flossing and regular dental visits can also help prevent dental disease.
An eating disorder can be traumatic for both patients and their families, and can take time to overcome. Even so, patients can reduce its effect on their dental health.

You're more apt to lose teeth because of periodontal (gum) disease and tooth decay than any other cause. But neither of these bacterial diseases have to happen: You can prevent them through daily brushing and flossing and twice-a-year dental cleanings.
But that's not all: You can also boost your dental care practices by eating foods that strengthen and protect teeth. On the other hand, a poor diet could reduce the effectiveness of your oral hygiene practices in preventing tooth decay or gum disease.
A diet that might lead to the latter is often high in refined sugar (sucrose), often added to processed foods and snacks to improve taste. But sucrose is also a top food source for oral bacteria, increasing their numbers when it's readily available. A higher bacterial population greatly increases your risk for tooth decay or gum disease.
On the other hand, certain foods benefit your overall dental health. Fresh fruits and vegetables, for example, are filled with nutrients and minerals like vitamin D or calcium that strengthen teeth against disease. And although they can also contain natural sugars, these don't pose the same problems as added sucrose due to the plant fiber you consume with them.
Dairy foods can also help you maintain healthy teeth and gums. Milk and cheese contain minerals like calcium and phosphorus, and a protein called casein, all of which strengthen teeth against decay. The enzymes in cheese stimulate saliva, which in turn neutralizes mouth acid and prevent it from harming enamel.
Some foods are also natural sources of fluoride, a mineral that strengthens tooth enamel. One example is black tea, which also, along with green tea, contains antioxidants that protect against cancer.
The best strategy for “tooth-friendly” nutrition is to pursue a diet that's high in fiber-rich natural foods and low in sugar-added processed foods. In practice, you'll want most of your diet to consist of fresh fruits and vegetables and low-fat dairy food, while minimizing foods with added sugar.
Following this kind of diet will certainly benefit your overall health. But it will also make it easier for you to prevent dental disease and keep your teeth and gums healthy.

Enamel is the hardest substance in the human body, and for good reason—it's your teeth's first line of defense against wearing and harmful oral bacteria. But although enamel can “take a licking and keep on ticking,” it can lose its mineral content, soften and eventually erode to expose the teeth to bacteria.
Here are 4 tips for protecting your enamel so it keeps on protecting you.
Practice sound brushing techniques. Brushing is necessary for removing bacterial plaque that can trigger dental disease. But how you brush could prove not only ineffective, but also harmful to your enamel. So, be sure you're brushing all tooth surfaces, but not too forcefully or too often (twice a day is enough)—otherwise, you could wear down enamel and damage your gums.
Wait to brush after eating. The acid levels in the mouth go up during eating, causing an immediate softening of enamel. But saliva then goes to work neutralizing acid and helping to restore enamel's mineral content. Since it takes saliva about thirty minutes to an hour to complete this task, wait on brushing at least that long. Otherwise, you might remove tiny traces of temporarily softened enamel.
Avoid eating right before bed. While we sleep, our saliva flow decreases until we wake up. If you eat just before bed, you may not be giving your saliva enough time to neutralize acid before it “goes to sleep” with you for the night. So, give your saliva ample time to neutralize any remaining acid by not eating anymore at least an hour before you turn in.
Limit drinking acidic beverages. Some of our favorite drinks—sodas, energy and sports drinks, and even some juices—can be high in acid. To protect your enamel, reduce your consumption of these types of beverages in favor of water or milk (the calcium in the latter will also benefit your enamel). When you do drink acidic beverages, use a straw to minimize contact of the fluid with your enamel.
Healthy and strong enamel is the key to healthy and strong teeth. It's worth taking these steps to protect this important defense against destructive tooth decay.

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.
