The chewing surfaces of your back teeth contain many intricate grooves and fissures that can easily trap plaque and food. These surfaces will often develop cavities and fissure sealants are an easy and non-invasive way to protect them and to prevent this from occurring.
What Are Fissure Sealants?
Fissure sealants are made from a flowable plastic material that is similar to composite resin. The sealant is simply painted onto the clean tooth and quickly hardens, forming a smooth, easy to clean surface. It will not interfere with your bite and fissure sealants are nearly invisible. Treatment should last for several years before your fissure sealants need renewing. It is a simple and cost-effective way to protect your back teeth from tooth decay.
Will Fissure Sealants Help Teeth with Fillings?
Unfortunately fissure sealants can only be applied to teeth that do not have any fillings or decay. Sometimes it might be possible for fissure sealants to protect teeth that only have the earliest signs of tooth decay, as their application helps to seal in bacteria, preventing decay from progressing any further, but it is rare for sealants to be used in this way.
