What Types of Dental Sealants used by Pediatric Dentist

Dental Sealants

In the world of pediatric dentistry, dental sealants play a crucial role in ensuring the oral health of young patients. These thin, protective coatings are applied to the surfaces of teeth to prevent decay and maintain healthy smiles. As a leading authority in the field, we are here to provide you with an extensive guide on the types of dental sealants used by pediatric dentists.

Kids Dentist Boca Raton utilizes a range of dental sealants tailored to address the specific needs of each child. This comprehensive article will equip you with all the essential knowledge you need to make informed decisions regarding your child’s oral health.

Understanding Dental Sealants

Before delving into the types of dental sealants, it’s essential to have a clear understanding of what these remarkable treatments are and how they work.

Dental sealants are thin, plastic coatings that are applied to the chewing surfaces of the back teeth, primarily the molars and premolars. These surfaces are particularly susceptible to tooth decay due to their deep grooves and fissures, which can trap food particles and bacteria. Pediatric dentists use sealants as a preventive measure to protect these vulnerable areas from decay, ultimately helping children maintain healthy teeth and avoid cavities.

Types of Dental Sealants

When it comes to dental sealants, there are primarily three types commonly used by pediatric dentists:

1. Resin-Based Sealants

Resin-based sealants are the most prevalent and effective type used in pediatric dentistry. These sealants are made of a tooth-colored resin material and offer outstanding protection for a child’s teeth. They are highly durable and can last for several years. The application process involves cleaning the tooth surface, etching it to create a rough texture, and then applying the sealant material. A special light is used to harden the sealant, ensuring it forms a strong bond with the tooth.

2. Glass Ionomer Sealants

Glass ionomer sealants are another option utilized by pediatric dentists. These sealants are suitable for children who may have difficulty staying still during the application process because they are less sensitive to moisture. Glass ionomer sealants release fluoride, which helps strengthen the tooth and protect against decay. However, they are not as long-lasting as resin-based sealants and may require more frequent reapplication.

3. Fluoride-Releasing Sealants

Fluoride-releasing sealants are a unique type of sealant that provides additional protection against cavities. They release fluoride over time, which helps remineralize the tooth’s surface and strengthen it against acid attacks. These sealants are often recommended for children who are at a higher risk of cavities. While they are effective, they may also require periodic reapplication to maintain their protective benefits.

The Application Process

Now that we’ve covered the types of dental sealants, it’s essential to understand the application process. Pediatric dentists follow a systematic procedure to ensure the sealant is applied correctly and effectively:

Cleaning the Tooth Surface: The first step involves thoroughly cleaning the tooth’s chewing surface to remove any plaque and debris.

Etching: A mild acid solution is applied to create a rough surface on the tooth. This rough texture helps the sealant bond securely to the tooth.

Application of Sealant: The sealant material is carefully applied to the tooth’s grooves and fissures. It flows into these areas and forms a protective barrier.

Hardening: To harden the sealant, a special curing light is used. This ensures that the sealant adheres firmly to the tooth.

Final Check: The dentist will perform a final check to ensure the sealant is properly in place, creating a durable barrier against decay.

Benefits of Dental Sealants

Dental sealants offer a wide array of benefits for pediatric patients and their parents:

  • Cavity Prevention: The primary purpose of sealants is to prevent cavities, which are a common dental issue in children. By sealing the vulnerable chewing surfaces, the risk of decay is significantly reduced.
  • Cost-Effective: Preventing cavities through sealants is a cost-effective strategy compared to treating cavities and dental fillings.
  • Painless and Quick: The application of sealants is a painless and quick process, making it ideal for children who may be anxious about dental procedures.
  • Durability: Depending on the type of sealant used, they can last for several years, providing long-term protection.
  • Enhanced Oral Health: Overall, dental sealants contribute to improved oral health, allowing children to maintain their natural teeth and smiles.


Dental sealants play a vital role in pediatric dentistry, serving as a valuable tool to prevent cavities and promote optimal oral health in children. As a responsible parent, it’s crucial to understand the types of dental sealants and their benefits, enabling you to make informed decisions for your child’s dental care. By collaborating with a pediatric dentist, such as the professionals at Big Tooth Boca, you can ensure that your child receives the best protection against tooth decay through the careful selection and application of appropriate dental sealants.
