Metal dentures are generally made from cobalt chrome or gold, they have the added benefit of being a lot stronger than acrylic dentures and can be used for full or partial prosthetics.
They can be made smaller due to their strength clasps to existing teeth and provide greater stability in the mouth on partial sets.
Cobalt chrome can also be used as a reinforcement in acrylic dentures offering extra strength where necessary.
Gold can look and feel great in the mouth but comes at a greater cost due to the value of gold, we can add gold teeth to any denture if required.
