In Asian countries, fluoride varnish and gel are usually imported products. The material cost is relatively high, especially
in low-income countries. This creates a barrier for the use of these agents. Fluoride varnish, being easy to apply and safe, has been the preferred agent for prevention of the early childhood caries that is prevalent in many developing countries in Asia. Several Southeast Asian countries are adopting or pilot-testing its use in public health programs for toddlers and preschool children. However, fluoride varnish is one of the more expensive topical fluoride agents. The development and production of low-cost fluoride varnishes locally will greatly help to promote this effective caries preventive method. Exemption from import and sales taxes, if any, will also help to lessen the problem.
