Braces have come a long way since their debut back way back around 1000 BC. Though these primitive forms of braces were not highly effective nor aesthetically similar to today’s braces, they likely made just enough impact to justify the effort. Formal orthodontic braces were not developed until the 19th century. As time has progressed, braces have gradually improved, as evidenced by today’s Invisalign clear aligners. These translucent teeth-straightening aligners are comfortable, quite effective, and barely visible.
