Gold Crowns

Historically they have been used mainly in molars that are difficult to see because these crowns are not colored like a natural tooth. Gold alloys are very strong and durable over time. In addition, because they are thinner than other metals, they require less tooth preparation.
They are biologically friendly to the oral environment and do not wear natural opposing teeth. In the past they were the best choice in case you grind your teeth.

These crowns for aesthetic reasons do not cover the outer-front surface of the teeth and thus the enamel of natural teeth is kept intact when circumstances allow.
They were used to provide the aesthetics of natural teeth on the outside while on the inside they provided strength, durability and elasticity for the rest of the tooth.
