Brushing technique
• Attach one of the brushheads to the handle. They can be
used with any kind of toothpaste.
• To avoid splashing, guide the brushhead to your teeth
before switching the appliance on.
• Guide the brushhead slowly from tooth to tooth.
• Hold the brushhead 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.
Pressure Sensor
For optimum brushing results
Oral-B
®
ProfessionalCare™
8900 DLX
has a pressure control feature to 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 oscil-
lating movement of the brushhead will continue but the
pulsation will stop. In addition to feeling it, you can also hear
a different sound.
Professional Timer
A short stuttering sound at 30-second intervals, which you
can hear and feel, reminds you to brush the four quadrants of
your mouth equally for a better overall clean.
2-Minute Timer
A long stuttering sound indicates when the dentist
recommended 2-minute brushing time has been reached.
During the first few days of using the 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 hygienist.
