Gingival Barrier

This is a 3 ml gingival blocker which is used to protect the gums from blanching. It is a blue resin which is applied and then "cured" with a UV light or allowed to dry under the whitening light. After it is cured it will become a solid blue line of plastic between the gums and the teeth, protecting the gum from the gel. When done properly, it will peel off in an even strip. See curing lights for this item under lights for excellent curing results.
