Today's "braces" are made of many different materials.
Metal brackets are typically made of stainless steel.
Clear braces are made of either porcelain, sapphire or plastic.
Aligners Invisalign are made out of multlilayer aromatic thermoplastic polyurethane / copolyester.
Modern wires are made from stainless steel, nickel titanium, molybdinum, copper, and traces of many other rare metals.
The o-rings and chains used to tie it all together are made of rubber, latex, or vinyl.
If you have allergies to any of these materials, be sure and mention it to your orthodontist at your first visit.
