CDC Wants More Kids to Get Dental Sealants

Fox News Health Report

The Centers for Disease Control and Prevention (CDC) urged U.S. schools Tuesday to bring in dental specialists to apply sealants on kids’ molars to help reduce cavities.

Research suggests dental sealants, which are quick and easy to apply, could prevent up to 80 percent of cavities among children, yet a CDC Vital Signs report suggested about 60 percent of kids ages 6 to 11 do not get them, according to a news release. The CDC encouraged schools to implement more school-based sealant programs (SBSPs) to target low-income school-age kids especially, as these children may not have access to regular preventive care.

“Many children with untreated cavities will have difficulty eating, speaking and learning,” CDC director Dr. Tom Frieden said in the release. “Dental sealants can be an effective and inexpensive way to prevent cavities, yet only one in three low-income children currently receive them. School-based sealant programs are an effective way to get sealants to children.”

The Vital Signs report found that while 43 percent of school-age kids ages 6 to 11 had a dental sealant, low-income children were 20 percent less likely to have sealants than higher-income children.

Other studies have suggested dental sealants prevent 80 percent of cavities two years after application and prevent 50 percent of cavities for up to four years after placement, according to the release. Dental sealants can remain in the mouth for up to nine years before they need to be reapplied.

Kids without sealants have nearly three times as many cavities as children with them, the Vital Signs report suggested.

By targeting schools with a high percentage of children eligible for free or reduced-cost meal programs with SBSPs, officials can help improve low-income students’ dental care, according to the CDC. In the release, the CDC urged officials to target schools in need in their state, track the number of schools and children participating in SBSPs, implement policies that deliver the programs with cost effectiveness, and help connect schools with health departments and specialists in the community. The CDC currently provides funding to 21 state public health departments to implement SBSPs for low-income students who live in rural parts of the United States.

Dental Sealants

What are dental sealants?

Dental sealants are plastic coatings that are usually placed on the chewing (occlusal) surface of the permanent back teeth — the molars and premolars — to help protect them from decay.

Why are dental sealants placed on teeth?

The chewing surfaces of the molar and premolar teeth have grooves — "fissures" — that make them vulnerable to decay. These fissures can be deep, are difficult to clean, and can be narrower than even a single bristle of a toothbrush. Plaque accumulates in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. Fluoride helps prevent decay and helps protect all the surfaces of the teeth, dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area.

When are dental sealants placed?

 The first dental sealant to be placed is usually on the fissure of the first permanent molar tooth, once the chewing surface of the tooth has erupted completely beyond the gum. This tooth grows in behind the baby teeth. If the chewing (occlusal) surfaces of these teeth are sealed, the dental sealant will help protect the tooth. Except for the wisdom teeth, which come through much later, the molars and premolars continue to erupt until eleven-thirteen years of age and the chewing surfaces of these teeth can be sealed after they have erupted beyond the gum.

Dental Sealants

Are dental sealants only placed on the chewing surface of molar and premolar permanent teeth?

Dental sealants are usually placed on the chewing surfaces of these teeth because these are the areas and teeth that typically have deep fissures. Dental sealants are sometimes also used on other permanent teeth if they have grooves or pits, to help protect these surfaces. In some children, the molars in the primary dentition (baby teeth) also have grooves that could benefit from dental sealants and in this situation your dentist or hygienist may recommend dental sealants on the chewing surfaces of these primary teeth.

Can dental sealants be place on the teeth of adults?

Yes — while less common, dental sealants are sometimes placed in adults at risk for caries, on deep grooves and fissures that do not already have fillings or dental sealants.

What do dental sealants look like?

Dental sealants can be clear, white or have a slight tint depending upon the dental sealant used.

How are dental sealants placed?

Firstly the tooth surface is thoroughly cleaned with a paste and rotating brush by your dentist or hygienist. Next the tooth is washed with water and dried. Then a solution that is acidic is placed on the fissured area of the tooth’s chewing surface for a number of seconds before being rinsed off. This creates small microscopic areas and a fine rougher surface than the surrounding tooth enamel, that can be seen with a microscope. The rough surface and microscopic areas enable the dental sealant to attach to the tooth. After the tooth is dried again, the liquid dental sealant is placed on the tooth and hardened. Dental sealants are hardened by using a light that hardens the dental sealant, or sometimes by using a two-component dental sealant that sets without using a light. Once the dental sealant has hardened it becomes a hard plastic varnish coating, and you can chew on the tooth again.

How long does a dental sealant last?

Dental sealants have been used and have been proven to be effective since the 1970s. Many studies have shown that they are effective in helping to prevent decay on chewing (occlusal) surfaces. Dental sealants can last many years. If necessary, it is also possible to place a new dental sealant on the tooth.

Do I still need to use fluoride if I have dental sealants?

Yes. Dental sealants only protect the surface area that they are placed on. Fluoride helps protect all the surfaces of the tooth from decay and cavities.

Do you know how sealants help prevent cavities?
Applying a thin plastic coating to your teeth makes it harder for the
plaque to stick to the tiny groves on the biting surfaces of the back
teeth - protecting the tooth surface and reducing the risk of forming
cavities....
We are offering 1/2 off special sealant placement. Call our office to set up your appointment today.

One of the most common spots for tooth decay to develop is on the chewing surfaces of the back teeth, also known as the premolars and molars. If you run your tongue along the chewing surfaces, you will feel rough grooves. The grooves, which are called pits and fissures, help to grind food.

Daily brushing and flossing help remove food particles and bacteria from the smooth surfaces along the sides of and between the teeth. However, pits and fissures are more difficult to keep clean. Toothbrush bristles cannot reach into the microscopic grooves to remove tiny particles of food or plaque.

Because pits and fissures are difficult to keep clean, your dentist may recommend protecting them with dental sealants, a special plastic coating that covers and seals the chewing surfaces. Sealants act as a barrier, protecting tooth enamel from plaque bacteria and acid.

Dentists have used sealants to protect teeth for several decades. They are safe and effective in preventing tooth decay. The likelihood of developing tooth decay on the chewing surfaces begins early in life, so children and teenagers are obvious candidates for sealants. Adults also can benefit from sealants, because one never outgrows tooth decay.

New research shows that dental sealants not only protect healthy teeth from decay, but they also can stop decay in its earliest stages, sealing in the bacteria and preventing a cavity that otherwise would require a restoration (filling).

The procedure is simple and quick with little, if any, discomfort. First, the dentist thoroughly cleans and prepares the teeth to be sealed. The dentist then applies the sealant to the tooth's chewing surface, where it bonds with the enamel. He or she may use a special curing light to help the sealant harden. The procedure requires one short visit.

As long as the sealant remains intact, the tooth's chewing surface will be protected from decay. Sealants, which hold up well under the incredible force of everyday chewing, may last for years before a reapplication is needed. However, no two mouths are the same, and chewing or grinding can cause sealants to wear at different rates. Regular dental visits are important so that your dentist can check the sealant and reapply it as needed.

Talk with your dentist to determine if dental sealants can help protect your teeth.

The application of systemic or topical fluoride since the early 1970’s has lowered the incidence of tooth decay on the smooth surfaces of the teeth. However, about 90% of the decay found in children’s teeth occurs in tooth surfaces with pits and fissures. To solve this problem, dental sealants were developed to act as a physical barrier so that cavity-causing bacteria cannot invade the pits and fissures on the chewing surfaces of back [posterior] teeth.

A sealant is a plastic resin material that is usually applied to the chewing surfaces of the back teeth—premolars and molars. This material is bonded into the depressions and grooves (pits and fissures) of the chewing surfaces and acts as a barrier, protecting enamel from attack by plaque and/or acids.

Dental sealants are usually professionally applied. The dentist, hygieniest or assistant cleans and dries the teeth to be treated; then paints a thin layer of liquid plastic material on the pits and fissures of the tooth. A blue spectrum natural light is shined on the applied material for a few seconds to cure the plastic. Some brands of sealants cure chemically.

After curing, the plastic becomes a hard, thin layer covering the treated portions of the tooth. Despite the incredible pressures placed on teeth during chewing each day, dental sealants often remain effective for five years or longer, although sealants do wear naturally and should be checked at regular intervals. If sealants wear or become damaged, they can be repaired or replaced simply by applying new sealant material to the worn or damaged portions.

Children should receive sealants shortly after the eruption of their first permanent molars, around age 6 and again at age 12 when their second molars appear.

During the child’s regular dental visits, we will check the condition of the sealants and reapply them when necessary.
