What are fissure sealants, and who are they suitable for? Fissure sealants play a pivotal role in preventive dentistry, offering a proactive approach to safeguarding teeth against cavities and decay. In this article, we delve into the intricacies of fissure sealants, exploring their purpose, the application process, and the individuals for whom they are most beneficial.

Demystifying Fissure Sealants

Fissure sealants play a crucial role in preventive dentistry, acting as a shield against the onset of cavities and dental decay. Let’s unravel the intricacies of fissure sealants, delving into their composition, application process, and suitability for various age groups.

Understanding Fissure Sealants


Fissure sealants are thin, protective coatings applied to the biting surfaces of molars and premolars. These surfaces, characterised by deep grooves and fissures, are prone to the accumulation of food debris and bacteria. Fissure sealants create a smooth surface, preventing plaque build-up and significantly reducing the risk of decay.


Typically made of a resin material, fissure sealants bond seamlessly to the tooth’s surface. The chosen resin ensures durability and biocompatibility, providing maximum protection without causing harm to surrounding tissues.

Application Process

The application of fissure sealants is a painless and straightforward procedure. After cleaning the tooth surface, the sealant material is painted onto the grooves and fissures. A curing light is then used to harden the sealant, creating a durable protective barrier.

Ideal Candidates for Fissure Sealants

Fissure sealants have proven to be a highly effective preventive measure against dental decay, especially on the biting surfaces of molars and premolars. Understanding who stands to benefit the most from fissure sealants is crucial in promoting optimal oral health. This section explores the ideal candidates for fissure sealants, addressing age considerations and specific risk factors. Fissure sealants

Who Benefits the Most?

1. Children and Teenagers

  • High Susceptibility: Children and teenagers often exhibit a higher susceptibility to dental decay due to dietary habits, difficulty in maintaining thorough oral hygiene, and the presence of newly erupted permanent molars.
  • Formative Years: Applying fissure sealants during these formative years provides a proactive defense against cavities, protecting the teeth during critical developmental stages.

2. Adults with Deep Fissures

  • Individual Risk Factors: Adults with deep fissures and a history of dental decay may benefit significantly from fissure sealants.
  • Targeted Prevention: While adults may have established oral hygiene routines, the targeted prevention offered by fissure sealants remains valuable in protecting vulnerable areas.

Age Considerations

While fissure sealants are commonly associated with paediatric dentistry, their effectiveness is not limited to a specific age group.


  • Timing is Crucial: Applying fissure sealants as soon as permanent molars erupt ensures timely protection during the most vulnerable period.
  • Preventive Measure: Fissure sealants act as a preventive measure, reducing the likelihood of cavities and the need for more extensive dental treatments.

Teenagers and Adults:

  • Continued Benefits: Teenagers and adults, especially those with deep fissures, can still benefit from fissure sealants.
  • Preserving Oral Health: The application of sealants helps preserve oral health by minimising the risk of decay in hard-to-reach areas.

Additional Considerations

1. Individual Tooth Anatomy

  • Deep Grooves: Teeth with deep grooves and fissures are more susceptible to trapping food particles and bacteria, making them ideal candidates for fissure sealants.

2. History of Dental Decay

  • Preventive Approach: Individuals with a history of dental decay can adopt a preventive approach by opting for fissure sealants to protect vulnerable surfaces.

The ideal candidates for fissure sealants encompass a broad spectrum, ranging from children in their formative years to adults with specific risk factors. Understanding the susceptibility of certain age groups and individual tooth anatomy aids in promoting targeted preventive care. Whether it’s providing a shield for a child’s newly erupted molars or offering continued protection for adults with deep fissures, fissure sealants play a vital role in preserving oral health across various stages of life.
