Fissure sealants are the safest way of protecting your children's teeth from the long lasting damage of tooth decay. So, just what are dental sealants? Essentially it's a material coating which covers the surface of the back teeth, creating a smooth surface which is easier to clean and maintain. The sealant itself forms a hard shield that protects your teeth from food and bacteria getting into small grooves in the teeth. 

Most decay in children tends to occur in the back of the mouth. More often than not, sealants are placed as soon as the adult molar teeth come through. As long as the sealants remain firmly in place, cavities and long lasting damage can be prevented. Sealants do wear away over time, but tend to have the potential to remain effective for five years or even longer in some cases.
