Kolorz ClearShield varnish seals dentin tubules reliably and aids in relieving hypersensitivity. Just like the other Kolorz hygiene products, ClearShield contains xylitol and fluoride. This provides peace of mind. ClearShield smiles look fantastic: the varnish goes on clear with no embarrassing discoloration or yellow teeth. The hygienically sealed single dose package eliminates cross-contamination and makes preparation and clean-up fast and easy.
