I have a bar at the back of my teeth, should I be using the orthodontic head on the back and normal on the front or can I use the same head for the whole mouth?
The orthodontic tip is designed to be used on any orthodontic appliance. We often find food and plaque getting caught around permanent retainers (bars). I would recommend using the brush tip along the bar (at the back of the teeth) and the regular tip at the front of those teeth.
