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.
