Dental Sealants- Burnaby, BC's Answer to Reducing Childhood Tooth Decay

Dental Sealants: Expert Answer from Vega Dental at Burnaby, BC to Reducing Childhood Tooth Decay

April 1, 2024

Maintaining optimal oral health is vital for individuals of all ages, especially during childhood when dental habits are established. Childhood tooth decay frequently arises due to the build-up of bacteria and dental plaque on the teeth, potentially leading to severe dental issues when not addressed promptly. We recognize the significance of safeguarding children’s smiles from cavities and offer an effective solution: dental sealants. These thin, plastic coatings act as a protective barrier against bacteria and plaque, reducing the risk of decay in vulnerable areas of the teeth. In this guide, we will learn about the benefits of dental sealants and how they play a vital role in protecting children’s smiles.

What Are Dental Sealants?

Thin plastic coatings, known as dental sealants, are applied to the back teeth’s chewing surfaces, specifically molars and premolars. These areas have deep grooves and fissures, creating spaces where food particles and bacteria can get trapped, heightening the likelihood of decay. Sealants serve as a protective barrier, sealing these vulnerable areas and averting cavity formation. The sealant material is composed of resin or glass ionomer, which bonds to the enamel of the teeth. After application, the sealants undergo hardening, creating a smooth surface that hinders the attachment of bacteria and plaque to the teeth. While sealants are commonly used in children, they can also aid adults who are at risk of developing cavities.

How Sealants Are Placed?

The procedure for administering dental sealants is straightforward and devoid of any discomfort. Here is what to expect during a sealant procedure:

  • Cleaning: The teeth undergo thorough cleaning and drying to eliminate any debris or plaque.
  • Preparation: An acidic solution is administered to the chewing surfaces of the teeth to induce a rough texture, enhancing the sealant’s adhesion.
  • Application: The sealant material is carefully painted onto the teeth and allowed to flow into the grooves and fissures.
  • Curing: A special curing light is used to harden the sealant, ensuring it forms a durable protective layer over the teeth.

Typically, the entire process can be completed during a single dental visit and requires no drilling or anesthesia, making it comfortable and convenient for patients of all ages.

The Protective Power of Dental Sealants in Preventing Childhood Cavities

A significant advantage of dental sealants is their efficacy in preventing childhood cavities. Here is how sealants safeguard children’s smiles:

  • Protection: By sealing the deep grooves and fissures of the teeth, sealants establish a physical barrier, effectively blocking bacteria and food particles. This reduces the risk of decay and helps keep the teeth healthy and cavity-free.
  • Longevity: With proper care, dental sealants can last for several years, providing continuous protection against cavities during the critical childhood years. This long-term benefit makes sealants a cost-effective preventive measure for parents seeking to safeguard their children’s oral health.
  • Non-Invasive: Unlike fillings or other dental procedures, sealants require no drilling or anesthesia. This makes them a comfortable and minimally invasive option for children who may feel anxious about visiting the dentist.
  • Cost-Effective: Opting for sealants early on can aid in preventing the necessity for more extensive and expensive dental treatments in the future. By protecting against cavities, sealants can save parents both time and money in the long run.

Who Needs Dental Sealants?

Although dental sealants offer advantages for individuals of various age groups, they are particularly advisable for children and teenagers prone to an increased risk of developing cavities. Factors that may increase the need for sealants include:

  • Deep grooves and fissures in the teeth that are difficult to clean effectively.
  • A history of cavities or dental decay.
  • Difficulty maintaining proper oral hygiene habits, such as brushing and flossing regularly.

Taking Care of Sealants

To guarantee the durability and effectiveness of dental sealants, it is crucial to uphold good oral hygiene and appropriately care for your teeth. Here are some tips for maintaining sealants:

  • Practice Good Oral Hygiene: Motivate children to engage in the habit of dental brushing twice a day using fluoride toothpaste and incorporating daily flossing into their oral care routine. This aids in removing plaque and bacteria from the teeth, thus preventing decay.
  • Attend Regular Dental Check-ups: Schedule routine dental visits to monitor the condition of the sealants and ensure they remain intact. Your dentist can also provide additional fluoride treatments to strengthen the teeth and enhance the protective benefits of sealants.
  • Avoid Chewing Hard Foods: Advise children to refrain from biting down on hard objects or foods that could damage the sealants. Sticky or chewy candies should also be avoided, as they can stick to the teeth and increase the risk of decay.
  • Protect with Fluoride: Use fluoride mouthwash or gel as directed by the dentist near you this helps strengthen the teeth and offers added protection against the development of cavities. Fluoride helps remineralize the enamel and can enhance the durability of dental sealants.


In conclusion, Dental sealants serve as a potent tool in combatting childhood tooth decay, providing a proactive approach to sustaining optimal oral health. By establishing a protective barrier on the chewing surfaces of the teeth, sealants effectively shield vulnerable areas from harmful bacteria and plaque, thus diminishing the risk of cavities.
