     BACKGROUND OF THE INVENTION 
     All existing toothbrushes in the market are in one piece, the head and the handle cannot be separated. Users will throw away the whole piece of toothbrush when they need replace a new one. But, the brush will be damaged faster than the handle that can be used for longer time than the brushes. Normally, the brushes can only be used for few months, but the handle can be used for years. This is a waste to throw away the whole piece of toothbrush. This waste is damaging our environment and earth.

     In order to protect our environment and earth, we need to reduce the wastes. If the head and handle of toothbrush can be separated, the head can be replaced, then the handle can be used for longer time, the wastes can be reduced. 
     The head and handle is connected by screwing. There is screw head at the top of handle and there is screw hole at the head, when the handle screw head put into the screw hole at the head and screw it, the head and handle can be screwed together firmly, just like a normal toothbrush.

     DETAILED DESCRIPTION OF THE INVENTION 
     The toothbrush of this invention can be used as normal brush to clean the teeth, but the head of the toothbrush can be replaced. The handle can be kept and used continuously. 
     There is a screw hole at the head of the toothbrush, and the head of the handle is also screw-typed. When the head of the handle put into the hole of the head and then screwed it, the head and the handle will be connected together, it will then become a normal toothbrush. Normally, the brushes will be damaged much faster than the handle. If the brushes are damaged, the head of the toothbrush can be screwed out and then thrown away. The handle head of the toothbrush can then be screwed into one new toothbrush head, the toothbrush can be used again as new one, this process can be repeated until the handle is damaged too. Therefore, the handle can be used for much longer time and we can reduce the waste and protect our environment.
