Dentures are not the only answer False teeth have been around for millennia. Humans have fashioned all sorts of materials together in an attempt to eat in order to survive. Over the centuries they have been made of everything from bone to wood, that resulted in ill-fitting, painful, noisy tooth substitutes. Things improved in the last century with the advent of resins. Conventional dentures can now be made to look very natural. Fit and function have been improved, but they fall short of natural teeth. A full denture affects speech and taste, and though it restores the ability to chew, it does nothing to retain the bone.
