your left hand. My advice is to train your left 

 hand to gain this, point, because it is the only 

 position that gives general satisfaction. You can 

 also place the left hand upwards into the mouth 

 on the right side of the jaw and guide the float 

 between the second and third fingers, and work it 

 with your right hand. 



There are still a few other methods. One of 

 these is the passing of your left hand into the 

 mouth on the right side and taking hold of the 

 tongue very firmly and passing it to the left side 

 of the mouth. Work the float with your right 

 hand and guide the shaft of it underneath the 

 wrist. In order to guide the shaft under the 

 wrist, raise the wrist upwards towards the roof

 to the interdental space, have the palm of the 

 hand turned downwards, and when the left side 

 of the tongue is reached with the fingers, the 

 palm of the hand is to be turned upwards. The 

 back part of the wrist is laid flat upon the lower 

 jaw, between the first molars and incisor teeth. 

 Placing your wrist in that position prevents the 

 tongue from slipping underneath it. The float is 

 worked with the right hand along the edges of 

 the inside part of the lower jaw teeth. The shaft 

 is guided by the thumb and first finger.

 left lower jaw teeth. Place the left hand into the 

 mouth, with the palm of your hand turned down,
