I believe the answer is: catgut tied to crude metal wires
The catgut is made by the intestines of mammals such as horse or sheep. Ancient Egypt was among the first one to use this method in order to preserve the teeth.
For wealthier citizens, they might use a more expensive metal for the braces. The Etruscans for example use gold as a form of brace in order to prevent tooth collapse.
That is a country, that's Brazil.

- The copyright protection can be sought for both published or unpublished work. It becomes legally binding for the buyer to pay for every copy of the work officially and legitimately produced.
A. Because the Egypt and Indus valley are in the desert, living near a river gave access to a food supply, water and better soil for growing crops. There were better resources to build shelter, and the river provided a safe route of transportation to other areas.
