In most cases, it will take between 30 minutes and an hour to get your relines done. It is a quick procedure, and you can take your dentures home the same day. If you choose a hard reline, it might take a little longer. Replacing the rubbery impression with the acrylic reline requires some skills. Your dentist might not be comfortable doing it. They will send your dentures to a specialized dental lab if this is the case. You will get your dentures back after a few days.
