Teeth lost to tooth decay can have devastating consequences for a child’s dental health. Not only can it disrupt their current nutrition, speech and social interaction, it can also skew their oral development for years to come.
Fortunately, we have a number of preventive tools to curb decay in young children. One of the most important of these, dental sealants, has been around for decades. We apply these resin or glass-like material coatings to the pits and crevices of teeth (especially molars) to help prevent the buildup of bacterial plaque in areas where bacteria tend to thrive.
Applying sealants is a simple and pain-free process. We first brush the coating in liquid form onto the teeth’s surface areas we wish to protect. We then use a special curing light to harden the sealant and create a durable seal.
So how effective are sealants in preventing tooth decay? Two studies in recent years reviewing dental care results from thousands of patients concluded sealants could effectively reduce cavities even four years after their application. Children who didn’t receive sealants had cavities at least three times the rate of those who did.
Sealant applications, of course, have some expense attached to them. However, it’s far less than the cost for cavity filling and other treatments for decay, not to mention future treatment costs resulting from previous decay. What’s more important, though, is the beneficial impact sealants can have a child’s dental health now and on into adulthood. That’s why sealants are recommended by both the American Dental Association and the American Academy of Pediatric Dentistry.
And while sealants are effective, they’re only one part of a comprehensive strategy to promote your child’s optimum dental health. Daily brushing and flossing, a “tooth-friendly” diet and regular dental cleanings and checkups are also necessary in helping to keep your child’s teeth healthy and free of tooth decay.
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.

Wouldn't it be wonderful if you could put up a protective shield to guard your children's teeth from decay? Think of the time and money you would save, not to mention the pain your children would avoid. Well, it turns out that you can put up such a protective shield — or at least, we, your dental professionals, can.
The natural protective mineral coating (the enamel) of a child's new teeth is more permeable to the acids that dissolve minerals and cause decay, so the new teeth are more vulnerable to tooth decay than mature teeth are. As a tooth's enamel matures it becomes more resistant and stronger. Thus it is important to protect the surfaces of the new teeth when they erupt (grow up through the child's gums).
The back teeth, particularly, often erupt with deep grooves in them. The backs of the top front teeth may also have such grooves, which dentists call “pits and fissures.” When the grooves are deep, they are hard to keep clean. Toothbrush bristles may not be able to reach to the bottoms of the grooves; and bacteria may gather in them, releasing acid byproducts that dissolve tooth enamel and start forming decay.
Dental sealants are among the preventive options we have in the war against decay in your child's new teeth. Regular tooth brushing and flossing, regular dental visits, application of fluoride, and low sugar consumption are also important in decay prevention techniques.
Sealants are protective coatings placed in the tiny pits and fissures to seal them off from bacterial attack. Some dentists routinely seal all permanent molar teeth and many primary (baby) molar teeth soon after they erupt.
Some dentists use sealants only when an examination shows that decay is just starting or very likely to start in a particular tooth. In such cases a minimal amount of tooth enamel is removed to eliminate any decay, and a mini-resin, invisible filling is applied.

The eruption of your child's first permanent teeth is a milestone in his or her development. As parents, you want to help your child preserve and protect their new permanent teeth so that they can last a lifetime. Dental sealants are one easy, simple, and inexpensive way to protect them from decay.
How do cavities develop?
The back teeth (premolars and molars) are formed with deep grooves on their biting surfaces that we call “pits and fissures.” These crevices are too deep for toothbrush bristles to reach. Bacteria can therefore grow and thrive inside them. The acid produced by these bacteria begins to dissolve the tooth enamel, starting the decay process.
Are new teeth more vulnerable?
Yes, the enamel surface of newly erupted teeth is more permeable and less resistant to tooth decay. As the enamel matures, it becomes more resistant.
How can you prevent decay in these new teeth?
Good oral hygiene habits, nutrition (including low sugar consumption), together with fluoride, sealants, and regular dental visits strengthen the teeth and can dramatically reduce tooth decay.
How does fluoride protect these teeth?
Fluoride makes the enamel surface harder and more impermeable and, therefore, less susceptible to acid attack and decay. Fluoride adds some protection to the deep pits and fissures of the teeth but they are still at high risk because of their shape and they often need further protection.
What are sealants and how do they work?
Sealants are protective coatings placed in the tiny pits and fissures to seal them from the bacteria and acids that promote decay. They actually “seal” the pits and fissures to prevent decay and can be used in the treatment of very early decay by arresting it. Greater use of sealants could reduce the need for subsequent treatment and prolong the time until treatment may become necessary.
