When PAP+ whitens, it oxidises tooth stains without releasing harmful molecules known as free radicals. These radicals are what damage enamel and cause severe sensitivity. This means during the whitening process there is no damage or erosion to the enamel, meaning the outer layers of the tooth remain intact and can continue to protect the nerves whilst being effectively whitened. The PAP+ whitening process targets a wide variety of tooth stains internally and externally and is clinically proven to show results instantly after 1 treatment. The PAP+ Strips offer a 30 minute, clean residue-free whitening treatment. You will see whitening results after just one use of the PAP+ Strips and can save remaining strips for future whitening maintenance.
