Replacing a separator If a separator comes out before your next appointment it is very easy to replace. The first step is to thread a piece of dental floss through the center of the separator.

The next step is to double the floss back on itself. Repeat this with one more piece of floss. Hold one piece of floss on either side of the separator.

Slide the floss between the teeth where the separator has come out.

Pull the separator through the contact.

Keep a finger on top of the newly placed separator. Gently pull one end of a doubled back piece of floss out of the mouth. Repeat with the other side.
