The modified bass technique of tooth brushing is used by patients that have good manual dexterity and limited gum recession.

The brush is placed at a 45-degree angle on to the front surface of the teeth with the bristles projecting into the pocket surrounding the tooth.

A small circular motion is made with the bristles into the pocket. Then the bristles are swept from the gum line into the biting surface of the tooth, brushing over the entire front surface. This technique is then completed on the inside surfaces of the teeth.  

The toothbrush is once again placed into the pocket at a 45-degree angle completing small circles, then brushed from the gum line to the biting surface of the tooth.
