Oral Care:

OraRez^® W forms protective films on teeth surfaces that resist erosion from saliva and acidic beverages. Dental tubes can be effectively protected to reduce dentinal hypersensitivity (Clin Oral Invest (2013) 17: 775-783).

The addition of OraRez^® W to toothpaste and mouth wash products can increase the effectiveness of active retention in the oral cavity to make products more efficacious at reducing both plaque and tartar formation (J Clin Dent, 2010, 21 [Spec Iss] 93-123).
