A floss threader is a simple dental tool that allows you to insert dental floss between your wires. It is basically a looped piece of floss that allows you to ‘thread’ regular dental floss into spaces between your teeth. To use a floss threader follow these steps: Get about 12 inches of dental floss. Insert one end of the dental floss into the loop of the threader, and pull about one-third of the floss through the loop. Pass the single thread side of the floss threader under your orthodontic appliances until about half of the loop is inside of your wires. Pull the remainder of the loop through the wire, which will pull the dental floss under the wire. Remove the floss threader, and gently floss back and forth to remove the popcorn kernel. If you are unable to remove the kernel using this method, it’s time to schedule an appointment with your orthodontist for further assistance. Don’t leave the kernel in and hope it works itself out! This can lead to serious oral issues in a short period of time. Related Post: How to Floss With Braces
