New Crest Toothpaste
 

Crest 3D supposedly:

-Can remove up to 80% of surface stains for a whiter smile in just 14 days.
-Unique fluoride toothpaste formula creates a foaming action that helps polish away surface stains to gently whiten teeth
-Special hybrid formulation offers the cleaning of a paste with the freshness of a gel

I wonder if you need special 3D glasses for that ;)

anyway, is that something that Rembrandt toothpaste already does?
