Sealants can protect your children’s back teeth, so that they may never need to have a filling! They are a protective plastic coating, which are applied to the chewing surfaces of teeth at risk of decay. The chewing surfaces of back teeth have small grooves or fissures which often extend right down into the tooth itself. However well the teeth are brushed, these fissures are very difficult to clean thoroughly. Bacteria and food particles stick to them and eventually cause decay. Fissure sealants completely seal off these grooves, preventing any food particles or bacteria from getting in. They do not affect the normal chewing function of teeth.
It’s best to get advice from your dentist or dental therapist if your child would benefit from fissure sealing the permanent back molar teeth.
