What is the best type of brush to use?

It is recommended that a small head, soft bristled brush be used. This is so that it can reach all confines of the mouth; especially the back molar teeth. The soft bristles again should be applied gently onto the surfaces of the teeth at the gum margins. The reason for this is to enable effective cleaning without any damage to the tooth or gum. Typical damage from heavy handed brushing includes permanent abrasion to the tooth’s surface  and even “stripping” of the gum, resulting in exposed root surface.  All of these may lead to teeth sensitivity, especially to hot and cold temperatures.
