Fixodent and Super PolyGrip are two of the top denture cream brands linked to serious nerve damage. People suffering nerve damage may experience pain and numbness in the hands and feet, difficulty walking, and even paralysis.
Zinc is used in denture creams as an adhesive and odor controller. While safe in small doses, too much zinc can be harmful. It decreases the body’s copper levels, which affects the spinal cord and leads to difficulty walking and keeping balanced. People using more adhesive denture cream than normal in order to keep poorly-fitted dentures in place may be exposed to up to 330 mg of zinc daily. The recommended daily allowance is only 8 mg for women and 11 mg for men, and the largest tolerable zinc intake is 40 mg.
