I lost my title for my new car

I recently purchased a new car and have been driving with a temporary license plate. Since my temporary plate will expire in 8 days, I am planning to register my new car. However, although the dealer said they sent the certificate of title, I have not received it yet, and I may need to apply for a duplicate title due to it being lost.

I have two questions. Can I use the duplicate title to complete the new car registration? And how long does it take to issue a duplicate title? My temporary plate has only 8 days left.
