How often do you brush your teeth?

I have found some electric toothbrushes are more 'harsh' than others.  There are also different head types for them.

I still have an older 'Sensi-Ultrathin' which isn't too harsh.  I just use the normal brush heads, often on offer in Supermarkets or Amazon.

I would advise anyone to avoid the Floss Action heads...  I got a free one with a new brush so thought I'd try it.  Didn't realise they have solid lumps of plastic within the bristles.  I managed to knock a tooth out of alignment when the plastic got in between two teeth!
