Health professionals have a new opportunity to help prevent tooth decay in young children and root caries in older people. Fluoride varnish is relatively inexpensive, easy to paint, concentrated topical fluoride with a resin or synthetic base. It is efficacious in reducing caries in primary and permanent teeth. The indications, contraindications, efficacy, uses and mechanism of action are discussed.
All of our e-learning courses are included in our Individual Subscription memberships.
On completion of this module you will understand the efficacy and contraindications for using fluoride varnish and recognise the opportunities for using it.
