Fissure Sealants


What is a Fissure Sealant?

Naturally the teeth have grooves and troughs, these are the valleys in between the cusps on the teeth. These grooves vary tooth to tooth. For individuals who are at high risk for cavities these grooves become a perfect spot for food and subsequently bacteria to infiltrate. In most cases, it is the back molars which are susceptible; however, other teeth may be at risk depending on the case. In cases were a fissure sealants is deemed necessary, a thin filling material used to seal over the grooves, to change the micro-environment limiting any decay risk.

Not everyone will need a fissure sealant. In some cases people may have stained crevices and grooves on their teeth, but unless an aesthetic issues the question is the overall risk of the individual and the activity of the lesion. In many cases small lesions can be strengthened through topical remineralizing fluorides or calcium and phosphate creams. If an individual is higher risk and if oral hygiene and prevention factors will not be enough to stop a lesion, a sealant may be considered.

Different Types of Sealants:

Resin Sealants – Are generally a harder material, and rely on direct bonding to the tooth structure. These sealants will slowly wear down over time.

Glass Ionomer Sealants – Are usually considered a softer material; however, these sealants have the benefit of being incorporated with properties to allow the tooth to heal; while the sealants slowly wears down over time.
