Earlier quoted context omitted.
Care to elaborate what the techniques your current dentist taught you?
With the regular 'brush compliance checks' mine does, an electrical toothbrush made significant difference. And it's not because I spend longer brushing, I even think I brush less in wall-clock time. The electrical one just seems to be more thorough ('seems' as in 'confirmed with dentist-administered plaque and gum health measurements', not 'I really want to believe so in my mind I make it so').
Now most of the work is maintenance on all those fillings, damage had been done, unfortunately.
