Professional Timer
For an overall clean, the «Professional Timer» helps you brush
the four quadrants of your mouth equally. It signals with a
short stuttering sound at 30-second intervals (45-seconds
intervals within «DeepClean» mode) that it is time to move to
the next quadrant of your mouth, followed by a long stuttering
sound when you reach the recommended 2-minute mark.
The «Professional Timer» memorizes the elapsed brushing
time, even when the handle is briefly switched off during
brushing. When pausing longer than 30 seconds, the timer
resets to the initial starting point.
In addition, a «smiley» is displayed when you reach the dental
professional recommended 2-minute brushing time. The
«smiley» will be displayed for 30 seconds before it disappears
automatically. Alternatively, you can directly clear the «smiley»
on the display by pushing the mode button.
Brushing
You can start your toothbrush by pressing the on/off button
(b). To avoid splashing, guide the brush head to your teeth
before switching the appliance on.
Brushing technique
•
Guide the brush head slowly from tooth to tooth.
•
Hold the brush head in place for a few seconds before
moving on to the next tooth.
•
Brush the gums as well as the teeth, first the outsides, then
the insides, finally the chewing surfaces.
•
Do not press too hard or scrub, simply let the brush do all
the work.
Oral-B SmartSeries 4000 has a pressure control feature to
help ensure that the right degree of pressure is applied. This
helps protect your gums from excessive brushing and makes
your toothbrush easy to operate. If too much pressure is
applied, the oscillating movement of the brush head will
continue but the pulsation will stop. In addition to feeling the
change, you can also hear a different sound.
In the first days of using your toothbrush, your gums may
bleed slightly. In general, bleeding should stop after a few
days. Should it persist after 2 weeks, please consult your
dentist or dental hygienist. If you have sensitive teeth and
gums, Oral-B recommends using the «Sensitive» mode.
