Yes, it's a dependent clause. It tells "why." What part of speech tells "why?"

Nouns don't tell why.

To identify the kind of clause in the sentence you provided, let's break it down:

Main clause: my friend Cooper needs to go to the orthodontist's office on Wednesday.
- This clause contains a subject ("my friend Cooper") and a verb ("needs").

Subordinate clause: because one of his brackets is loose.
- This clause begins with the subordinating conjunction "because" and provides additional information about the reason for my friend Cooper needing to go to the orthodontist's office.

Based on the information provided, the second clause "because one of his brackets is loose" is an adverb dependent clause. It functions as an adverb because it modifies the main clause by indicating the reason for my friend Cooper's need to go to the orthodontist's office.

Therefore, the correct answer is "adverb dependent."
