After a brush with relegation last season, the 2008/09 Bundesliga champions have again looked toothless so far this term averaging just a goal-a-game after eight Matchdays.
Schmidt, who was appointed last month to fill the role vacated by Andries Jonker, explained how the humble toothbrush could put smiles back on the faces of the club's fans by improving their heroes' on-pitch output.

"When you are completely drained, there is an acid reaction," the former Mainz boss said. "The acid goes into the bloodstream and can influence recovery."
Magath regime returns
Schmidt has also added a drill to his squad's training regime that is almost as feared as that of the team dentist: 'the hills of suffering' made famous by the man who crowned his reign with the club's historic title win, Felix Magath.
The short, sharp dashes to the top of the inclines are to build explosiveness, "which you need in football," stated Schmidt. With a winter camp planned for the Iberian peninsula, the pain in Spain will fall mainly on those who train under the Swiss tactician.
