Sometimes it seems that appearances count for everything—especially in Hollywood. But just recently, Lonnie Chaviz, the 10-year-old actor who plays young Randall on the hit TV show This Is Us, delivered a powerful message about accepting differences in body image. And the whole issue was triggered by negative social media comments about his smile.
Lonnie has a noticeable diastema—that is, a gap between his two front teeth; this condition is commonly seen in children, but is less common in adults. There are plenty of celebrities who aren’t bothered by the excess space between their front teeth, such as Michael Strahan, Lauren Hutton and Vanessa Paradis. However, there are also many people who choose to close the gap for cosmetic or functional reasons.
Unfortunately, Lonnie had been on the receiving end of unkind comments about the appearance of his smile. But instead of getting angry, the young actor posted a thoughtful reply via Instagram video, in which he said: “I could get my gap fixed. Braces can fix this, but like, can you fix your heart, though?”
Lonnie is raising an important point: Making fun of how someone looks shows a terrible lack of compassion. Besides, each person’s smile is uniquely their own, and getting it “fixed” is a matter of personal choice. It’s true that in most circumstances, if the gap between the front teeth doesn’t shrink as you age and you decide you want to close it, orthodontic appliances like braces can do the job. Sometimes, a too-big gap can make it more difficult to eat and to pronounce some words. In other situations, it’s simply a question of aesthetics—some like it; others would prefer to live without it.
There’s a flip side to this issue as well. When teeth need to be replaced, many people opt to have their smile restored just the way it was, rather than in some “ideal” manner. That could mean that their dentures are specially fabricated with a space between the front teeth, or the crowns of their dental implants are spaced farther apart than they normally would be. For these folks, the “imperfection” is so much a part of their unique identity that changing it just seems wrong.
So if you’re satisfied with the way your smile looks, all you need to do is keep up with daily brushing and flossing, and come in for regular checkups and cleanings to keep it healthy and bright. If you’re unsatisfied, ask us how we could help make it better. And if you need tooth replacement, be sure to talk to us about all of your options—teeth that are regular and “Hollywood white;” teeth that are natural-looking, with minor variations in color and spacing; and teeth that look just like the smile you’ve always had.
Because when it comes to your smile, we couldn’t agree more with what Lonnie Chaviz said at the end of his video: “Be who you want to be. Do what you want to do. Do you. Be you. Believe in yourself.”

The traditional way to restore a tooth with an artificial crown takes several weeks and multiple office visits: from tooth preparation and impression molding to crown production by a dental laboratory, followed by adjustments and cementing. Now, there’s an alternative that reduces this process to a fraction of the time, and all from your dentist’s office.
Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) is a digital system that enables dentists to create dental restorations with laboratory-grade materials in minutes rather than weeks. As it continues to innovate, you’ll see more and more dentists investing in the new technology for their patients.
A crown restoration with CAD/CAM begins like any other with decay removal and preparation of the tooth. It diverges, though, from the traditional in how an impression of your teeth and gums is obtained: instead of rubber-like molding materials to create a physical impression, we lightly dust the mouth interior with a reflective powder. Using a scanning wand, the reflective powder allows us to capture multiple, detailed images of your mouth that the CAD/CAM computer transforms into an accurate three-dimensional model.
We use the model to first assess if the tooth has been effectively prepared for a restoration. If so, the design feature of the system will provide us with thousands of tooth forms to choose from to match with your natural teeth. You’ll be able to view the proposed size and shape of the new crown via computer simulation before signing off on the design.
Next is the actual manufacture of the crown that takes place right in the dentist’s office. A pre-formed block of ceramic material is inserted in the milling equipment where, following the pre-determined computer design, the milling heads carve the ceramic block. After milling, we fine-tune the crown surface and apply stains or glazes fired to create a life-like color and texture that matches your natural teeth. We can then adjust the crown in your mouth and permanently affix it to the tooth.
While much of the CAD/CAM system is automated, ultimate success still depends on the dentist’s expertise and artistry. CAD/CAM enhances those skills with greater precision and in much less time than traditional crowns. It’s certainly a growing option for many people to restore the form and function of decayed teeth.

X-rays are an important diagnostic tool in dentistry because of their ability to penetrate and pass through body tissues. Because they penetrate at different speeds depending on tissue density (shorter and thus darker on exposed film for soft tissues, longer and lighter for hard tissues like bone or teeth), we’re able to detect decay which appear as dark areas on x-ray film.
Without x-rays, the early detection and diagnosis of dental problems would be quite difficult. But despite its obvious benefits, it’s still a form of released energy that exposes patients to a certain amount of radiation. Since the potential health risk from radiation depends on the amount released (the dosage) and for how long and often a person is exposed, we must determine if the dosage and frequency from dental x-rays is a cause for concern.
It’s a common misconception to view any radiation exposure as dangerous. The truth is, however, we’re all exposed daily to radiation from the natural environment — about 2 to 4.5 millisieverts (the dosage measurement for radiation exposure) a year, or about 10 microsieverts (one-thousandth of a millisievert) every day.
In comparison, radiation exposure from routine dental x-rays is a fraction of this if measured over time. A set of four bitewing images of the back teeth produces 4 microsieverts of radiation, less than half the average daily exposure. One of the most comprehensive x-ray sets, a full mouth series of 18-20 images using “D” speed film, results in an exposure of 85 microsieverts, equaling about a week of normal radiation exposure.
These thoroughly researched rates help demonstrate that regular dental x-rays are relatively safe. What’s more, x-ray technology has continued to advance since first used in the mid-20th Century. With innovations in film and digital processing, today’s equipment produces only 80% of the radiation exposure of earlier machines. In effect, we’ve increased our capabilities to more accurately detect and diagnose issues through x-rays, while lowering the amount of radiation exposure.
Of course, a person’s annual exposure rate may differ from others. If you have concerns for yourself or your family about x-ray radiation exposure, please feel free to discuss this with us. Our primary goal is to improve your oral health without undue risk to your health in general.
