What technique should I use?
When brushing your teeth it is best to position your toothbrush at a 45-degree angle to your teeth, aiming the bristles of your brush toward the gum line. The join between the teeth and the gum is a nice area for bacteria and plaque to accumulate, so it is important to get to this area.
Once you have the brush at the correct angle, all you need to do is jiggle the brush gently back and forward, only brushing one or two teeth at a time. Don’t be excessively vigorous but also don’t be too mild.
Remember. You are trying to penetrate the bristles into the gaps between teeth to remove a very soft plaque.
You need to be systematic – brushing all teeth in order, inside and outside – and you really should do it in front of a mirror so you can see what you are doing.
