How To Put The Separators In
Get two pieces of floss and your spacer.
Thread the two pieces of floss through the spacer, and then wrap the floss strings around your pointer fingers.
Pull fingers away from each other so the spacer is now almost flat and tension is created.
Just like you would floss between your teeth, gently work the spacer between your teeth. After you have pushed the spacer between the teeth, carefully pull the floss out. Sometimes it is necessary to hold your finger over the spacer when you pull the floss out.
