Is fluoride varnish toxic?

The simple answer is no. We use varnish with kids and patients with high caries risk to help arrest caries development. It coats the teeth leaving them feeling sticky. For four hours after application restricts hot beverages and brushing. We do take precaution if you are pregnant or kids under 1 year old.
