A Parent’s Guide to Dental Sealants for Kids in North Dallas: Protection for Growing Smiles Posted on April 18, 2025

Dental sealants are thin, protective coatings applied to the chewing surfaces of children’s back teeth to prevent tooth decay. In North Dallas, you’ll find that pediatric dentists regularly recommend sealants as an effective preventive measure against cavities in children. At Children’s Dentistry of North Dallas, our team sees firsthand how dental sealants help protect young smiles during the cavity-prone years. This comprehensive guide answers the most common questions parents have about dental sealants, from their application and benefits to costs and maintenance.

What Are Dental Sealants? Understanding This Protective Treatment for Kids

Dental sealants are clear or slightly tinted plastic coatings that dentists apply to the chewing surfaces of children’s molars and premolars. The sealant material flows into the deep grooves, pits, and fissures of teeth where decay often begins, creating a smooth protective barrier that prevents food particles and bacteria from settling in these hard-to-clean areas.

What is dental sealant material made of?

Dentists apply a special plastic resin material to kids’ teeth when placing dental sealants. This BPA-free resin hardens quickly with a special curing light and bonds directly to the tooth enamel. In our dental office, we use high-quality, biocompatible dental sealant materials that are specifically formulated for pediatric patients.

Are sealants the same as fillings?

Dental sealants are not the same as fillings; they serve fundamentally different purposes in children’s dental care. Sealants are preventive treatments applied to healthy teeth to stop decay before it starts. Fillings, on the other hand, are restorative treatments used to repair teeth after decay has already caused damage. Sealants preserve the natural tooth structure, while fillings replace portions of the tooth that have been removed due to decay.

Do dental sealants contain BPA or fluoride?

Modern dental sealants used at reputable North Dallas pediatric dental practices like Children’s Dentistry of North Dallas contain minimal to no BPA (Bisphenol A). Most dental sealants do not contain fluoride as their primary mechanism is to create a physical barrier rather than remineralize the tooth. Parents concerned about materials can ask their North Dallas dentist about the specific sealant products used and their composition.

What Are the Benefits of Dental Sealants for Children?

Dental sealants provide significant cavity prevention benefits for children by creating a physical barrier against bacteria and food debris. Research shows that sealants reduce the risk of decay in molars by nearly 80% for the first two years after application and continue to protect against 50% of cavities for up to four years. Our experienced pediatric dentistry team recommends sealants as an essential part of preventive care.

How effective are dental sealants in preventing cavities?

Dental sealants are extremely effective in preventing cavities in children, reducing decay by up to 80% in sealed molars compared to unsealed molars. The Centers for Disease Control and Prevention (CDC) confirms that school-age children without sealants have almost three times more cavities than children with sealants. In North Dallas, pediatric dentists observe this preventive effect regularly in patients with properly maintained sealants.

What is the success rate of dental sealants?

The success rate of dental sealants exceeds 90% when properly applied and maintained. Clinical studies show that well-placed sealants remain fully functional for several years before potentially needing reapplication. At Children’s Dentistry of North Dallas, our careful application technique and quality materials contribute to high success rates and long-lasting protection for pediatric patients.

Why does our North Dallas practice recommend sealants for kids?

Our North Dallas dentists recommend sealants for kids because they provide a cost-effective, non-invasive way to prevent the most common form of childhood tooth decay. The deep grooves in children’s molars are particularly vulnerable to decay and difficult for children to clean properly. Sealants address this vulnerability directly. Additionally, preventing cavities through sealants helps North Dallas families avoid more costly and uncomfortable treatments like fillings, crowns, or extractions later on.

What Age Should Kids Get Dental Sealants?

Children should get dental sealants as soon as their permanent molars erupt, typically around ages 6 for first molars and 12 for second molars. This timing maximizes protection during the cavity-prone years when children may not have perfected their brushing techniques.

Do dentists still put sealants on baby teeth?

We sometimes put sealants on baby teeth, especially if the child has deep grooves in their primary molars or is at high risk for cavities. Although primary teeth will eventually fall out, early childhood decay can cause pain, affect speech development, and create problems for the permanent teeth. At Children’s Dentistry of North Dallas, we evaluate each child individually to determine if sealants on primary teeth would be beneficial.

Is there an age limit for dental sealants?

There is no strict upper age limit for dental sealants, but they are most beneficial when applied shortly after tooth eruption. Teenagers and even adults can receive sealants if their teeth are free of decay and have deep grooves that could benefit from protection. The ideal candidates are children ages 6-14, as this is when they are most susceptible to developing cavities in newly erupted permanent molars.

Are 6-year molars permanent and should they get sealants?

Six-year molars are indeed permanent teeth and are prime candidates for dental sealants. These first permanent molars typically emerge around age 6 and have deep grooves that can trap food and bacteria. Because these teeth need to last a lifetime and are particularly vulnerable during the early years after eruption, most North Dallas pediatric dentists strongly recommend applying sealants to these teeth shortly after they emerge.

How Are Dental Sealants Applied to Kids’ Teeth in North Dallas?

Dental sealants are applied to kids’ teeth through a simple, painless process that takes only a few minutes per tooth. The procedure involves cleaning the tooth, applying an etching solution to create a better bonding surface, painting on the sealant material, and hardening it with a special light.

Who applies dental sealants in North Dallas practices?

Licensed dental professionals, including dentists, pediatric dental specialists, and dental hygienists apply dental sealants in North Dallas pediatric dental practices. At Children’s Dentistry of North Dallas, our skilled dental team members are specifically trained in working with children to ensure the sealant application process is comfortable and effective, even for anxious young patients.

How long does it take to apply dental sealant?

The dental sealant application process takes approximately 5-10 minutes per tooth. A typical appointment for sealing all four permanent first molars takes about 30-45 minutes, including preparation time. Children’s Dentistry of North Dallas schedules appropriate appointment lengths to ensure the process is unhurried and comfortable for young patients.

How Long Will Dental Sealants Last?

Dental sealants typically last between 5-10 years with proper care and maintenance. The longevity depends on factors such as the child’s chewing habits, the quality of application, and the type of sealant material used. Regular dental check-ups allow our North Dallas dentists to monitor sealant condition and recommend reapplication if necessary.

How often do kids need sealants?

Kids generally need sealants applied only once per eligible tooth, with potential reapplication if the sealant becomes damaged or wears away significantly. Most children receive sealants twice during childhood, once when their 6-year molars erupt and again when their 12-year molars come in. At Children’s Dentistry of North Dallas, we evaluate the condition of sealants during regular check-ups and recommend reapplication only when necessary.

What is the #1 reason sealants fail?

The primary reason dental sealants fail is improper application or partial loss of the sealant material over time. Factors that contribute to sealant failure include moisture contamination during application, excessive wear from grinding or chewing hard foods, and natural wear over time. Our dentists minimize these risks through careful isolation techniques during application and high-quality materials that bond securely to the tooth surface.

Can dental sealants come off or be removed?

Dental sealants can gradually wear away or partially come off over time as a natural part of the chewing process. If necessary, a dentist can deliberately remove sealants using special instruments without damaging the underlying tooth. However, since sealants provide valuable protection, they are typically only removed if they’re damaged or need replacement. At routine check-ups, our North Dallas dentists will assess if any sealants need repair or replacement.

Can My Child Eat After Getting Dental Sealants?

Children can eat and drink normally immediately after getting dental sealants. The sealant material hardens completely within minutes of application, allowing for immediate return to normal activities and eating habits without special restrictions.

Are there any food restrictions with new dental sealants?

There are no specific food restrictions with new dental sealants, as they harden completely before the child leaves the dental office. However, to maximize sealant longevity, dentists may recommend avoiding extremely sticky or hard foods like taffy, caramels, or hard candies, which can potentially damage sealants over time. Regular healthy eating habits will help maintain both the sealants and overall dental health.

What Are the Disadvantages or Risks of Dental Sealants?

Dental sealants have minimal disadvantages or risks compared to their substantial benefits. The main considerations include the possibility of trapped decay if not properly applied, potential allergic reactions to materials (extremely rare), and the need for occasional reapplication or monitoring.

What are the pros and cons of teeth sealants?

The pros of teeth sealants include:

Significant reduction in cavity risk (up to 80%)
Painless, non-invasive application
Long-lasting protection (5-10 years)
Cost-effective compared to treating decay
No visible change to tooth appearance

The cons of teeth sealants include:

Possible need for reapplication after several years
Potential to seal over very small existing decay if not detected
Slight possibility of BPA exposure (though minimal in modern materials)
Not a replacement for regular brushing and flossing
May need occasional repair if partially damaged

Can you still get cavities with sealants?

Children can still develop cavities with sealants in place, though the risk is significantly reduced. Sealants only protect the chewing surfaces where they are applied, leaving other areas of the teeth vulnerable if proper oral hygiene isn’t maintained. Additionally, if a sealant becomes damaged or partially detaches, decay can develop underneath. Regular dental check-ups help ensure sealants remain intact and effective.

What are the side effects of dental sealants?

Side effects of dental sealants are extremely rare. Occasionally, patients might experience temporary alteration in bite sensation that resolves quickly as they adjust to the thin layer of sealant material. Allergic reactions to sealant components are possible but exceptionally uncommon. The minimal BPA exposure from some sealants has been studied extensively and found to be far below levels of concern according to the American Dental Association.

How Much Do Dental Sealants Cost for Kids in North Dallas?

Dental sealants in North Dallas typically cost between $30-$60 per tooth without insurance. Most dental insurance plans cover sealants for children, either partially or fully, as they are considered preventive care. The total cost depends on how many teeth are sealed and whether any preparatory cleaning is needed.

Are dental sealants expensive compared to other preventive treatments?

Dental sealants are not expensive compared to other preventive treatments or to the cost of treating decay. Sealants represent one of the most cost-effective preventive dental measures available. The one-time cost of sealing a tooth is significantly less than the expense of filling a cavity, which can cost $150-$300 per tooth in North Dallas. Our dental office offers sealants as part of our comprehensive preventive care approach because they provide excellent value for families.

Why are sealants covered by insurance?

Insurance companies cover dental sealants because they prevent more costly dental problems in the future. From an insurance perspective, paying for preventive sealants reduces the likelihood of paying for fillings, crowns, root canals, or extractions later. Most dental insurance plans cover sealants for children up to age 14, reflecting the strong evidence supporting their effectiveness in preventing decay during the cavity-prone years.

Are sealants worth the money for North Dallas families?

Dental sealants are definitely worth the money for North Dallas families, offering substantial long-term savings by preventing decay. A single sealant costs a fraction of what treating a cavity would require, both financially and in terms of discomfort. Additionally, preventing decay preserves natural tooth structure and helps avoid the cycle of dental work that can occur when teeth need repeated treatment over a lifetime. In our dental office in North Dallas, we consider sealants an essential investment in your child’s long-term oral health.

What Alternatives to Dental Sealants Are Available in North Dallas?

The main alternatives to dental sealants include regular fluoride treatments, vigilant home care routines, and dietary modifications. While these approaches are valuable components of oral health care, they don’t provide the same physical barrier protection that sealants offer for deep grooves in molars.

How can I protect my child’s enamel without sealants?

To protect your child’s enamel without sealants, implement these strategies:

Ensure thorough brushing twice daily with fluoride toothpaste
Supervise and assist young children with brushing until age 7-8
Incorporate daily flossing to clean between teeth
Schedule regular professional fluoride treatments
Maintain a diet low in sugary foods and acidic beverages
Use a straw for acidic drinks to minimize contact with teeth
Schedule regular dental check-ups

While these methods help maintain overall dental health, they don’t provide the same targeted protection for molar grooves that sealants offer.

Frequently Asked Questions (FAQs)

What is the best dental sealant for children?

The best dental sealant for children is a resin-based material that provides durable protection and contains minimal BPA. In our dental office, we use high-quality, clear or tooth-colored sealants that allow us to monitor the sealed area while providing maximum protection. The “best” sealant often depends on the individual child’s needs, tooth anatomy, and risk factors, which is why we perform thorough evaluations before recommending specific materials.

What does a cavity look like compared to a sealed tooth?

A cavity typically appears as a dark brown, black, or white spot on a tooth, often with a rough or soft texture when probed by a dental instrument. In contrast, a sealed tooth has a smooth, slightly shiny surface where the sealant material fills in the natural grooves. While unsealed teeth show natural deep fissures that may collect debris, properly sealed teeth exhibit a flat or gently contoured chewing surface that’s easier to clean and resistant to decay.

How many teeth do kids have, and which ones typically get sealants?

Children typically have 20 primary (baby) teeth and eventually develop 32 permanent teeth. Dental sealants are most commonly applied to the permanent first and second molars (usually 4 teeth at age 6 and 4 more at age 12), though premolars may also receive sealants if they have deep grooves. In North Dallas, most pediatric dentists evaluate each child individually to determine which teeth would benefit most from sealant protection based on their anatomy and cavity risk.

Why do some sealants turn brown over time, and is this a problem?

Some dental sealants may discolor slightly over time due to food and beverage staining at the margins where the sealant meets the tooth. This discoloration is primarily an aesthetic issue and doesn’t usually affect the sealant’s protective function. During regular check-ups, we evaluate any discoloration to determine whether it’s simply staining or indicates a need for sealant replacement. As long as the sealant remains intact and the tooth underneath is healthy, slight discoloration is not a clinical concern.
