The TWO MOST IMPORTANT feature on toothbrush
Although toothbrush has evolved quite a bit and there are dozens of choice in the market currently, they all serve one purpose: remove plaque build up on teeth.
The most important features to look for in a toothbrush are:
-soft bristles, medium is considered too hard
-relatively small head
Shape of the head and the bristle do not make a significant difference.
Electric toothbrush works as well as a manual toothbrush so long as they both used correctly and toothbrushing has been done thoroughly.
