Here's are examples of braces appearing on '70s television commercials. This post is put together from content on previous posts on this blog.
When I was young kid, braces were much less common, and being told you needed braces was something that was dreaded by kids and teens who had to undergo orthodontic treatment. This toothpaste commercial from the mid '70s shows the awkwardness of showing up at school for the first time with braces.Check out this orthodontic Public Service Announcement from the 1970s. In this one, it looks like braces were really catching on with adults. But I remember the '70s, and braces weren't all too "groovy" with teens, much less grown ups.
