Have you heard about dental sealants? These preventive treatments have been available for many decades, and more and more children are taking advantage of them. The National Institutes of Health (NIH) estimates that around 30% of kids from 6 to 11 years of age have had sealants applied to their molars (back teeth). Sealants are designed to reduce the incidence of cavities by filling in or eliminating the pits or crevices found in all molars, where decay-causing bacteria can hide and your brush can't reach. But do they really work?
Now, the research is in, and the answer is clear — YES!
Two major studies, each of which reviewed the results of thousands of patients over several years, recently came to the same conclusion: Dental sealants are effective at reducing cavities, and their benefits can last for four years (or more) after application. In general, the studies showed that kids who didn't get sealants were twice, three times, or even more likely to get cavities, compared to kids treated with sealants.
Sealants themselves are protective coatings made of plastic resins or glass-like materials. They are applied in liquid form, and then hardened by a special light. When “painted on” to the chewing surface of a molar, sealants fill in the tiny crevices, or “pits and fissures,” that are found there. Uneven tooth surfaces form a perfect breeding ground for the bacteria that cause tooth decay; worse yet, the bristles of a tooth brush can't usually reach them. That's what makes these areas highly susceptible to tooth decay.
Applying sealants is a quick and painless procedure that doesn't require any numbing shots or drilling. Many kids start getting sealants when the first permanent molars come in, around age 5 to 7; they may have more sealant treatments when additional molars emerge, between the ages of 11 and 14.
Sealants are recommended by the American Dental Association and the American Academy of Pediatric Dentistry, and have only a modest cost per tooth. On the other hand, having a cavity filled generally costs substantially more, and may result in more trouble (and expense) down the line — so sealants can make sense economically, as well as preventively. This is especially true for those at high risk for tooth decay.

Tooth decay is as relentless as it is destructive, and it makes little distinction between age, gender, ethnicity or social status. Although risk levels vary from person to person, we’re all potentially in the crossfire for this harmful disease. Getting ahead of it early could save your teeth.
Tooth decay begins with oral bacteria. While feeding on dental plaque that accumulates on the teeth, bacteria multiply and produce acid as a by-product. Too much acid softens and erodes tooth enamel, which enables decay to advance deeper into the tooth.
If it isn’t stopped, decay can eventually infect and weaken the roots and bone, and ultimately lead to a lost tooth. By stopping it as early as possible before it reaches the inner pulp and root canals, we can greatly limit the damage.
Regular dental care is crucial for early detection. Here’s how we can stay ahead of developing decay during dental visits.
Visible inspection. There are visible signs a trained dentist may notice that point to tooth decay. Besides an already formed hole or cavity, we might also pick up on other unusual appearances like white spot lesions: these slight blemishes often occur in the areas of contact with other teeth, which we can treat with topical fluoride.
X-rays. This tried and true diagnostic tool has been a mainstay of dental care for nearly a century. The images they produce can indicate decay as darker spots or areas on or within the tooth that may not yet be visible to the eye. And with advances in digital processing and more streamlined equipment, we can effectively do this with a very low dosage of radiation exposure.
Advanced technology. We’ve developed other means for better disease detection that complement x-rays and visual inspections. Specialized microscopes and lasers are now important tools for analyzing suspected areas of early decay.
Even if decay gets a foothold we can effectively stop it and restore a tooth with a root canal treatment or a similar procedure. The best outcome, though, is to not allow this destructive disease to get that far. With dedicated oral hygiene and regular dental visits that uncover early decay, chances are good your teeth can remain healthy for a lifetime.

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.”
