Acrylic dentures are made from acrylic resins with denture teeth bonded to the acrylic base. These dentures are an option for people who do not like the idea of metal in their mouth. It is easier to add teeth to an acrylic denture but as acrylic is weaker than metal acrylic dentures are easier to break.
With acrylic dentures clasps (wire clips) are often used to engage the remaining teeth to position and hold the denture in place. If you are worried about metal showing then nylon clasps are an option.
Acrylic dentures can be relined and repaired.
