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.

Buffalo Bills wide receiver Stefon Diggs wrapped up the NFL regular season in January, setting single-season records in both catches and receiving yards. The Bills handily beat the Miami Dolphins, earning themselves the second seed in the AFC playoffs, and Diggs certainly did his part, making 7 catches for 76 yards. But what set the internet ablaze was not Diggs' accomplishments on the field but rather what the camera caught him doing on the sidelines—flossing his teeth!
The Twitterverse erupted with Bills fans poking fun at Diggs. But Diggs is not ashamed of his good oral hygiene habits, and CBS play-by-play announcer Kevin Harlan expressed his support with “Dental hygiene is something to take note of, kids! There's never a bad place to floss” and “When you lead the NFL in catches and yards, you can floss anytime you want.”
We like to think so. There's an old joke among dentists:
Q. Which teeth do you need to floss?
A. Only the ones you want to keep.
Although this sounds humorous, it is borne out in research. Of note, a 2017 study showed that people who floss have a lower risk of tooth loss over periods of 5 years and 10 years, and a 2020 study found that older adults who flossed lost an average of 1 tooth in 5 years, while those who don't lost around 4 teeth in the same time period.
We in the dental profession stress the importance of flossing as a daily habit—and Stefon Diggs would likely agree—yet fewer than 1 in 3 Americans floss every day. The 2016 National Health and Nutrition Examination Survey (NHANES), conducted by the CDC's National Center for Health Statistics, revealed that only 30% of Americans floss every day, while 37% floss less than every day and 32% never floss.
The biggest enemy on the football field may be the opposing team, but the biggest enemy to your oral health is plaque, a sticky film of bacteria and food debris that builds up on tooth surfaces. Plaque can cause tooth decay and gum disease, the number one cause of tooth loss among adults. Flossing is necessary to remove plaque from between teeth and around the gums where a toothbrush can't reach. If not removed, plaque hardens into tartar, which can only be removed by the specialized tools used in the dental office. Regular professional dental cleanings are also needed to get at those hard-to-reach spots you may have missed.
If Diggs can find time to floss during a major NFL game, the rest of us can certainly find a couple minutes a day to do it. While we might not recommend Diggs' technique of flossing from one side of the mouth to the other, we commend his enthusiasm and commitment to keeping his teeth and gums healthy. Along with good dental hygiene at home—or on the sidelines if you are Stefon Diggs—regular professional dental cleanings and checkups play a key role in maintaining a healthy smile for life.
Teenagers can have the same smile-disrupting tooth flaws as adults. But not all cosmetic treatments available to adults are appropriate for teenagers—at least not until they get a little older. Dental veneers fall into that category.
A veneer is a thin porcelain shell custom-made by a dental lab, and bonded by a dentist to the face of a tooth to mask chips, stains, gaps or other imperfections. Because they're less invasive than other measures, veneers are highly popular as a cosmetic dental solution. They do, however, usually require some enamel removal so that they'll appear more natural.
This enamel removal typically won't impact an adult tooth other than it permanently requires it to have veneers or other restorations after alteration. But there is a risk of damage to a teenager's tooth, which hasn't fully developed.
Adolescent teeth usually have a larger pulp chamber (filled with an intricate network of nerves and blood vessels) than adult teeth. And because the enamel and dentin layers may not yet be fully developed, the pulp is much nearer to the tooth's surface.
We must be very careful then in removing enamel and dentin for veneers or we may penetrate the pulp and risk damaging it. Alternatively, there is the possibility of no-prep veneers which are very conservative but often are unable to be done because of the need to often remove tooth structure to make the veneers look natural.
Another cosmetic problem can occur if we place veneers on a patient's teeth whose jaws and mouth structures are still growing. Eventually, the gums could recede and an unsightly gap form between the veneer and the adjacent natural tooth.
Fortunately, there are other techniques we can use to improve a tooth's appearance. Mild chipping can be repaired by bonding composite resin material to the tooth. Some forms of staining may be overcome with teeth whitening. These and other methods can address a teenager's smile appearance until their teeth are mature enough for veneers.
Whether or not a tooth is ready for veneers will depend on its level of development, something that can often be ascertained with x-rays or other diagnostic methods. And if a tooth has already undergone a root canal treatment, there isn't as much concern. In the meantime, though, it may be better for your teen to wait on veneers and try other techniques to enhance their smile.

Do you want to give your child something that will benefit them the rest of their life? Then give them the gift of healthy teeth and gums.
Such a gift doesn't come wrapped in a box with a bow on it—you bestow it first by ensuring they receive the utmost in dental care during their formative years. Even more importantly, you instill in them good oral care habits that will protect their dental health for the rest of their lives.
Oral Hygiene 101. Daily hygiene—brushing and flossing to remove disease-causing dental plaque—is the foundation for maintaining a lifetime of optimal dental health. Early on, you'll have to perform these tasks for your child, but the true gift is in teaching them to brush and floss effectively for themselves (and your dentist can help too!).
How's my brushing? There's oral hygiene—and then there's effective oral hygiene. For a quick check, there's a simple test you can teach your child to make sure they're brushing and flossing correctly: Just after they finish, have them rub their tongue all along their teeth. If the teeth feel smooth, they've made the grade! If it feels gritty, though, they'll need to try again. (For better accuracy, you can also purchase a disclosing solution at your local pharmacy that when applied to teeth will reveal any remaining plaque.)
Eating for dental health. Instilling the values of proper nutrition not only promotes your child's overall health, it can also help them have healthier teeth and gums. Foods rich in vitamins and minerals, especially vitamin D, calcium and phosphorus, help build strong teeth and bones. Avoiding processed foods, especially those with added sugar, helps them avoid tooth decay or gum disease.
Mouth protection from injury. As your child grows and becomes more active, they're more at risk for injury to their mouth, teeth or gums. Help them break habits like chewing on hard objects, and insist on them wearing a mouthguard while playing sports. As they enter the teen years, encourage them to avoid “mouth jewelry” that could damage their tooth enamel.
These values and practices are often woven into the fabric of everyday life. They take relatively little time, but they can make a huge impact on your child's oral health future.

Learning you're pregnant can change your life in a heartbeat—or now two. Suddenly, what was important to you just seconds before the news takes a back seat to the reality of a new life growing within you.
But although many of your priorities will change, there's one in particular that shouldn't—taking care of your dental health. In fact, because of the hormonal changes that will begin to occur in your body, your risk of dental disease may increase during pregnancy.
Because of these hormonal variations, you may find you have increased cravings for certain foods. If that includes eating more carbohydrates (especially sugar), bacteria can begin to multiply in your mouth and make you more susceptible to tooth decay and periodontal (gum) disease.
The hormones in themselves can also increase your risk of gum disease in particular. There's even a name for a very common form of gum infection—pregnancy gingivitis—which affects around two-fifths of pregnant women. If not treated, it could aggressively spread deeper within the gums and endanger both your teeth and supporting jaw bone.
The key to minimizing both tooth decay and gum disease is to keep your mouth clean of dental plaque, a thin bacterial biofilm most responsible for these diseases. You can do this by keeping up daily brushing and flossing and maintaining regular dental cleanings and checkups. Professional dental care is especially important during pregnancy.
You may, though, have some reservations about some aspects of dental care, especially if they involve undergoing local anesthesia. But many medical organizations including the American Congress of Obstetricians and Gynecologists and the American Dental Association recommend dental treatment during pregnancy. Even procedures involving local anesthesia won't increase the risk of harm to you or your baby.
That said, though, elective dental work such as cosmetic enhancements, might be better postponed until after the baby is born. It's best to discuss with your dentist which treatments are essential and should be performed without delay, and which are not. In general, though, there's nothing to fear for you or your baby continuing your regular dental care—in fact, it's more important than ever.
