It probably isn't an infection, at least, severe enough to warrant any antibiotics. The area may still need some time to heal. Keep the area clean and gently irrigate the socket. The sutures may have helped food getting stuck in the area. With the sutures removed, food should be less likely trapped in that area. If you keep the area clean, the gums will gradually grow back and fill in the space. If the symptoms or problem worsens, I would recommend going back to your dentist.

Thank you for your comments. I forgot to mention that the surrounding gums were also puffy, but they seem to have come down with the remedies I'm using. A little afraid to clean too much or harshly with the syringe I was using so am just rinsing now. Thank you again for your help, it is appreciated.
