ELI5:Why are braces so expensive ?

All braces are is a bunch of small metal pieces and a wire.

The whole thing probably cost under 3$ to make so, why exactly does it costs over 3000$-7000$ for basic metal braces in my country (Canada) ?

The materials are not that expensive. What you're actually paying for is the dentist's skills in applying the braces, the time spent in maintaining it (you'll visit the dentist on numerous occasions to have it adjusted) and the dentist's reputation.
