Fittydent Lower Denture Adhesive Cushions are a guaranteed solution for denture wearers with very flat and/or narrow lower jaws. The environment of the lower denture is very different from that of the upper denture. There is less surface area for suction, the tongue tends to dislodge the lower denture, and it is exposed to more saliva, constantly keeping it in a moist environment. Fittydent Adhesive Cushions provide a secure hold, even with excess saliva.
