Placing Implants Into Infected Area

A patient from New York asks us:

I recently had a dental implant fail and my dentist told me that he would replace it in 3 weeks, which to me sounds rushed.

I have found information leading in both directions on the time to wait or
immediate replacement. Is there a generally accepted time to wait?
Prior to dental implant placement, I had an infected tooth that was removed.
Waited one month to have the dental implant placed. I experienced significant
pain after the implant was placed that lasted 2 weeks, starting around
the 3rd day after dental implant placement. Any ideas!?! Thoughts?
