Dentures are an important and essential part of dentistry.
Dentures can be sometimes the only treatment available.
There are full and partial dentures.
Full dentures are always made out of acrylic (a form of plastic), however partial dentures can be made out of acrylic (plastic) or chrome(metal).
In general metal dentures are thin, durable and more comfortable to wear.
However acrylic dentures have their advantages too and provide a good option as temporary dentures.
