Plaque buildup? Brushing harder vs. brushing longer vs brushing more frequently.

Plaque can only build up if you don't remove it all at each brushing. If you remove 99%, each time you brush, it builds up. If you have a build up problem (and lets face it - few of us don't) you might ask yourself  "Can I stop the buildup by brushing harder/longer/more frequently?"

Because of the way plaque hardens progressively the best way is to brush more frequently, that way you catch the plaque while is is at its softest.
