Enzymatic dentifrices
First Claim
1. An enzyme dentifrice chewing gum or tablet consisting of about 0.5 to about 20 units per gram/milliliter of glucose oxidase enzyme which forms hydrogen peroxide by oxidative decomposition of a glucose substrate provided by glucose present in sufficient amount in saliva and tooth plaque, said hydrogen peroxide being formed in a continuous concentration no greater than 10-4 %, said unit being the quantity of the enzyme which will oxidize 1 micromol of substrate per minute at 30°
- C. and pH 6, effective when applied to a dental surface exhibiting a pH below the neutral range, to restore the pH at said dental surface to an approximately neutral range, anda pharmaceutically acceptable carrier.

Abstract
A novel enzymatic dentifrice comprises as its essential active ingredient an amount of glucose oxidane enzyme which forms hydrogen peroxide by oxidative decomposition of a glucose substrate provided by glucose present in saliva and tooth plaque so as to cause a substantial shift toward neutral values in the pH at the surface of teeth, when said pH is below the neutral range.
