Electric Tooth Brushes

Electric Toothbrush was developed in Scotland, in 1939 but it did not appear on the market unitl the 1960s, when it was marketed as the Broxodent in the US. General Electric (GE) introduced a new cordless rechargeable Electric Toothbrush that moved down and up when it is activated. The first rotary action toothbrush appeared in the market for home use in 1987. 
Currently there are many varieties of different model that use this electric mechanism. It is found from the research that they tend to be somewhat effective in preventing gingival and removing plaque bleeding than vibrating toothbrushes and manual toothbrushes.
