If your brush has two speeds, and uses brush heads with slim-angled necks, then you have a Sonicare Elite. An Elite toothbrush has a thread collar screw on brush head.
If the motion of the toothbrush is sufficiently rapid to produce a hum in the audible frequency of human range (20 Hz to 20,000 Hz), it can be classified as a sonic toothbrush. Any electric toothbrush with movement faster than this limit can be classified as an ultrasonic toothbrush.he effectiveness of an electric toothbrush depends not only on its type of action and on correct use, but also on the condition of the brush head. Most manufacturers recommend that heads be changed every three to six months at minimum, or as soon as the brush head has visibly deteriorated.
