Benefits of Fissure Sealants
Prevention: By helping to prevent cavities, fissure sealants can reduce the need for more extensive dental treatments.
Simple and Child-Friendly: The procedure is usually straightforward, non-invasive, and generally comfortable for children.
Ongoing Protection: Fissure sealants can provide protection for several years, but their lifespan varies. They may wear down or become partially lost and need repair or replacement. Your dentist will check them during dental reviews.
Easier Cleaning: Sealants cover deep grooves on the chewing surfaces of back teeth, helping to reduce trapped food and plaque. They do not replace regular brushing with fluoride toothpaste or cleaning between teeth.
Additional Considerations
Fissure sealants may be made from resin-based or glass-ionomer materials. Your dentist will assess whether sealants are appropriate and discuss the material, benefits, limitations and costs. Sealants reduce decay risk on treated surfaces but do not prevent all tooth decay. They may need repair or replacement, and irritation of the soft tissues in the mouth can occasionally occur. Ongoing cleaning, a balanced diet and dental reviews remain important.
Frequently Asked Questions
When Should Fissure Sealants Be Applied?
Sealants are often considered as permanent molars come through, particularly where deep grooves or a higher risk of decay are identified. The timing depends on tooth eruption and individual assessment, rather than age alone. Not every child or every tooth needs sealants.
How Does the Procedure Work?
The tooth is first cleaned, etched, rinsed, and dried before the sealant is applied and hardened. This process is quick and does not usually require anaesthetic.
What Happens After Application?
Follow your dentist’s advice about eating after treatment, as instructions may vary with the material used. Continue normal oral hygiene and contact the practice if the bite feels uncomfortable or the sealant appears damaged or lost.
Who Should Get Fissure Sealants?
Fissure sealants may be suitable for teeth with deep grooves or those at high risk for cavities, particularly in children with poor enamel quality or existing decay in adjacent teeth. Your dentist will advise whether sealants are recommended for your child.
Coverage and Maintenance
Eligible fissure sealant treatment may attract benefits under the Child Dental Benefits Schedule (CDBS), subject to eligibility, item restrictions and the child’s remaining benefit balance. Private health insurance benefits depend on the policy and applicable limits. Ask for a treatment quote and confirmation of expected benefits and out-of-pocket costs before proceeding. Your dentist will recommend reviews to check whether the sealants remain intact.
