Fissure Sealants in Singapore

Overview

Fissure sealants are preventive protective coatings applied to the grooves of molar teeth to reduce the risk of decay in areas that are difficult to clean effectively.

The chewing surfaces of back teeth often contain deep pits and fissures where plaque and food particles may accumulate. Even with good brushing habits, these narrow grooves may remain vulnerable.

Sealants act as a barrier over these surfaces, reducing the likelihood of bacterial penetration and early cavity formation.

Why Molars Are More Susceptible

Permanent molars erupt with complex surface anatomy. Deep grooves can trap debris and are not always accessible to toothbrush bristles.

Children and adolescents may be particularly susceptible during the early years after eruption, when enamel maturation is still ongoing.

Sealant application supports protection during this vulnerable period.

Who May Benefit from Fissure Sealants

Sealants are commonly recommended for children and teenagers after eruption of permanent molars.

Adults with deep fissures and high caries risk may also be considered.

Suitability depends on:

• Tooth eruption stage
• Groove depth
• Oral hygiene patterns
• Decay risk profile

Teeth must be free from active decay before sealant placement.

The Sealant Application Process

Application is non-invasive and does not require removal of tooth structure when performed on healthy enamel.

The tooth surface is cleaned, prepared, and dried before the sealant material is applied and hardened.

The process is typically completed in a single visit.

Regular review ensures sealant integrity over time.

Longevity and Maintenance

Sealants may remain effective for several years, depending on chewing forces and maintenance.

Periodic examination allows assessment of wear or partial loss. If necessary, sealants can be repaired or reapplied.

They function as part of a broader preventive strategy including brushing, fluoride exposure, and routine dental review.

Considering Fissure Sealants?

If newly erupted molars exhibit deep grooves or increased susceptibility to decay, evaluation allows assessment of suitability for preventive sealant application.

Appointments may be arranged during routine preventive visits where appropriate.
