The lingual bar is a great way to keep the lower anterior teeth in place, but it can be quite a pain to keep clean!  Dr. Danielak is very familiar with this, as she used to have a lower lingual bar herself.  But the above video shows a very useful trick to get the floss underneath the bar without using a floss threader.  For those of you who have a fixed retainer that is connected to each tooth, we are sorry to tell you that this trick will not work for you.  Happy Flossing!
