Dental sealants are a simple, effective way to protect your child’s teeth from cavities. At Knoxfield Dental Care, we often recommend sealants for children to provide a strong barrier against decay, especially on the back teeth where brushing can be tricky.

What Are Dental Sealants?

Dental sealants are thin, protective coatings applied to the chewing surfaces of the back teeth (molars and premolars). These areas have deep pits and fissures that can trap food and bacteria, making them prone to cavities. Sealants act as a shield, smoothing out the surface and preventing plaque from accumulating.

The sealant material is a tooth-coloured resin that bonds to the enamel, creating a physical barrier. They are typically applied to permanent molars as soon as they erupt, usually around age 6 and again around age 12. However, they can also be placed on baby teeth if your child is at high risk for decay.

At our Knoxfield clinic, we tailor sealant treatment to your child’s individual needs, ensuring the best protection for their growing smile.

Key Benefits of Dental Sealants for Children

The primary benefit of dental sealants is their proven effectiveness in preventing cavities. According to the Australian Dental Association, sealants can reduce the risk of decay in molars by up to 80%. This is a significant advantage for children who are still developing good brushing habits.

Other benefits include:

Sealants are painless and non-invasive, requiring no drilling or numbing.

They are quick to apply, usually taking just a few minutes per tooth.

Sealants are cost-effective compared to the expense of treating cavities and fillings.

They are safe and made from BPA-free materials (when appropriate, we can discuss options).

Sealants can last for several years with proper care, though they may need to be reapplied as they wear down.

• Reduces risk of cavities by up to 80% in molars
• Painless and quick application
• Cost-effective prevention
• Safe and durable

The Procedure: What to Expect

Getting dental sealants is a straightforward and comfortable process. Here’s what happens during a typical visit at Knoxfield Dental Care:

First, the dentist will clean your child’s teeth thoroughly to remove any plaque or debris. Then, each tooth is dried and isolated with cotton rolls to keep it dry. An acidic gel is applied to the chewing surface for a few seconds to roughen the enamel, which helps the sealant bond better.

After rinsing and drying, the sealant is painted onto the tooth and cured with a special blue light to harden it. The entire process usually takes about 30 minutes, depending on how many teeth are sealed. Your child can return to normal activities immediately after.

The procedure is painless, and most children find it easy because there is no drilling or needles. We always explain each step in a friendly, reassuring way to make your child feel at ease.

Are Sealants Right for Your Child?

Most children benefit from dental sealants, but certain factors can indicate a higher need. We often recommend sealants if your child has:

Deep pits and fissures on their molars (which are more prone to trapping food)

A history of cavities or a high risk of decay

Difficulty maintaining good oral hygiene, especially in the back of the mouth

Orthodontic appliances (like braces) that can make cleaning harder

During your visit, our team will assess your child’s teeth and discuss whether sealants are a good option. We always provide personalised advice based on their oral health needs.

Caring for Sealed Teeth and Ongoing Prevention

Dental sealants are durable, but they are not a substitute for good oral hygiene. To keep the sealed teeth healthy:

Encourage your child to brush twice a day with fluoride toothpaste and floss daily.

Limit sugary snacks and drinks, which can contribute to decay.

Schedule regular check-ups and cleanings with our team every six months.

During these visits, we will check the condition of the sealants and reapply them if necessary. With proper care, sealants can last for years.

At Knoxfield Dental Care, we are committed to helping your child maintain a healthy smile. Our friendly team is here to answer any questions you have about dental sealants or other preventive treatments.
