What are Fissure Sealants?
A Fissure sealant is a protective plastic coating applied to the biting surfaces of the back teeth. The sealant forms a hard shield that keeps food and bacteria from getting into the tiny grooves in the teeth and causing decay. This technique is completely pain free.
Which teeth should be sealed?
Fissure sealants are only applied to the back permanent teeth consisting of the molars and premolars. These are the teeth which have pits and fissures on their biting surfaces. After an examination our dentist in Watford can determine whether the fissures are deep enough to indicate need for fissure sealing. (Some teeth naturally form with deep grooves, which will need to be sealed, others with shallow ones which will not need sealing).
How is it done?
First the tooth is thoroughly cleaned, prepared with a special gel (like shampoo), and dried. The liquid sealant is then applied and is set hard by shining an ultraviolet light onto it. This process is quick and simple, taking only a few minutes per tooth.
