What Are the Advantages of Dental Sealants for Children?

May 3, 2024

Dental sealants are an essential preventive measure designed to safeguard children’s teeth from decay and cavities. As parents, safeguarding the oral health of our children is paramount. Dental sealants are essential for preserving healthy smiles and averting future dental problems. In this inclusive guide, we will dive deeper into the benefits of dental sealants for children and why they are crucial for preserving optimal oral health.

Understanding Dental Sealants

Dental sealants can be described as thin plastic coatings that are settled on the chewing surfaces of the rear teeth, like molars and premolars. These sealants serve as a protective shield by sealing the intense grooves and pits on the teeth where bacteria and food debris often gather. By providing a smooth surface, dental sealants hinder bacteria from accumulating in these inaccessible areas, lowering the chances of decay and cavities. Various types of dental sealants are accessible, such as resin-based and glass ionomer sealants, each with distinct advantages.

Importance of Dental Sealants for Children

Children are especially prone to tooth decay as they are still learning oral hygiene practices and making dietary decisions. Dental sealants are essential for shielding children’s teeth from cavities and decay, providing numerous advantages:

  • Vulnerability to Tooth Decay: Children are at risk of tooth decay because of their intake of sugary foods and beverages, along with insufficient oral hygiene practices.
  • Prevention of Cavities: By forming a protective barrier, dental sealants seal the susceptible areas of the teeth, preventing bacteria from causing decay.
  • Early Intervention: Applying tooth sealants at a young age can help prevent the need for more invasive dental procedures, such as fillings and root canals, in the future.

Benefits of Dental Sealants

The benefits of dental sealants extend beyond cavity prevention:

  • No Alteration of Tooth Structure: Dental sealants are applied to the natural tooth surface without altering its structure, preserving the integrity and strength of the tooth while providing an added layer of protection against decay.
  • Long-Term Cost Savings: Investing in dental sealants can save money on costly dental treatments for cavities and fillings.
  • Non-Invasive Procedure: The application of dental sealants is quick, painless, and does not require drilling or anesthesia, making it ideal for children.
  • Promotion of Good Oral Hygiene: By protecting the teeth from decay, sealants encourage children to follow the best oral hygiene habits, including brushing and flossing regularly.

Application Process

Dental sealant application is a simple process that can be completed in a single dental visit:


  • The dentist begins by thoroughly cleaning the teeth that will receive the sealants.
  • This involves removing any plaque, debris, or food particles from the chewing surfaces of the teeth.


  • Once the teeth are clean, the dentist prepares them for the sealant application.
  • This may involve roughening the surface of the teeth slightly to ensure better adhesion of the sealant.


  • The dentist isolates the teeth to be sealed, typically using cotton rolls or a dental dam.
  • This helps to keep the teeth dry during the application process, ensuring optimal bonding of the sealant.

Application of Etchant:

  • A special acidic solution, called etchant, is applied to the chewing surfaces of the teeth.
  • The etchant helps to create a rough surface on the enamel, allowing the sealant to bond more effectively.

Rinsing and Drying:

  • After the etchant has been applied and allowed to sit for a brief period, the teeth are rinsed thoroughly with water.
  • The teeth are then dried completely to ensure that the sealant adheres properly.

Application of Sealant:

  • Once the teeth are dry, the dentist applies the sealant to the chewing surfaces of the teeth.
  • The sealant is a tooth-colored resin material that is carefully painted onto the pits and grooves of the teeth.


  • After the sealant has been applied, it is hardened using a special curing light.
  • The light activates the sealant, causing it to bond to the tooth enamel and form a protective barrier.


  • Once the dental tooth sealant has been cured, the dentist evaluates its placement and ensures that it covers all the pits and grooves of the teeth.
  • Any excess sealant is trimmed away, and the teeth are polished to ensure a smooth finish.

Final Instructions:

  • Before the child leaves the dental office, the dentist gives instructions on how to care for the sealants.
  • This may include avoiding sticky or hard foods that could dislodge the sealants and maintaining good oral hygiene habits.


  • The dentist may ask to schedule a follow-up appointment to check the sealants and make any necessary adjustments.
  • It is advisable to have regular dental check-ups to assess the status of dental sealants and maintain ongoing protection against cavities.

Common Concerns and Misconceptions

Despite their effectiveness, some parents may have concerns or misconceptions about dental sealants:

  • Safety: Dental sealants are safe and approved by dental associations for use in children.
  • Effectiveness: Dental sealants are highly effective in preventing cavities when applied correctly.
  • Application Process: Getting dental sealants in Philadelphia, PA, is quick and painless, ensuring minimal discomfort for children.

Long-Term Effects and Maintenance

Dental sealants are highly durable and can stay for many years with proper care and maintenance:

  • Durability: Dental sealants can withstand the wear and tear of everyday chewing and brushing.
  • Monitoring for Wear: Parents should monitor their children’s sealants for signs of wear or damage, such as chipping or cracking. If any issues are detected, they should contact their dentist for evaluation and possible repair.
  • Fluoride Supplementation: In some cases, dentists may recommend fluoride supplementation for children with dental sealants to further enhance protection against decay and strengthen the enamel.
