Connecting and charging
Your toothbrush has a waterproof handle, is electrically safe and
designed for use in the bathroom.
• Plug the basic charger (g) or the assembled charging unit (picture
B/C) into an electrical outlet and place the toothbrush handle (d) on
the charging unit.
• The green charge indicator light (e) flashes while the handle is being
charged. Once it is fully charged, the light turns off. A full charge can
take up to 22 hours and enables up to seven days of regular
brushing (twice a day, 2 minutes) (picture 1).
Note: After deep discharge, the green light might not flash
immediately; it can take up to 10–15 minutes.
• If the rechargeable battery is low the red low charge indicator light (f)
is flashing for some seconds when turning your toothbrush on/off.
• For everyday use, the toothbrush handle can be stored on the
charging unit to maintain it at full power. Overcharging is impossible.
• To maintain the maximum capacity of the rechargeable battery,
unplug the charging unit and fully discharge the handle with regular
use at least every 6 months.
• Before plugging the basic charger (g) or the assembled charging
unit (picture B/C) into an electrical outlet, please adjust the plug to
correctly position the ground pin first. Hold the plug with the fuse
(labeled «FUSE») facing upwards. Place your thumb on the end of
the grey ground pin and lift it up. Continue to pull the ground pin
assembly (labeled «Thin plug») towards the fuse until it clicks into
place and is ready for use. Place the toothbrush handle (d) on the
charging unit (depending on model).
Using your toothbrush
Wet brush head and apply any kind of toothpaste. To avoid splashing,
guide the brush head to your teeth before switching on the appliance
(picture 2). When brushing your teeth with one of the Oral-B
oscillating-rotating brush heads guide the brush head slowly from
tooth to tooth, spending a few seconds on each tooth surface (picture
5). When using the Oral-B «TriZone» brush head place the toothbrush
bristles against the teeth at a slight angle towards the gumline. Apply
light pressure and start brushing in back and forth motions, just like
you would do with a manual toothbrush (picture 6).
With any brush head start brushing the outsides, then the insides and
finally the chewing surfaces. Brush all four quadrants of your mouth
equally. Do not press too hard, simply let the brush do all the work. You
may also consult your dentist or dental hygienist about the right
technique for you.
In the first days of using any electric 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/or gums, Oral-B recommends using the
«Sensitive» mode (depending on model) (optional in combination with
an Oral-B «Sensitive» brush head).
Brushing modes (depending on model)
(for handle type 3756)
Daily Clean – Standard for daily
Sensitive – Gentle, yet thorough
cleaning for sensitive areas
polishing for occasional or
Gum Care – Gentle massage of
How to switch between modes:
Your toothbrush automatically starts in «Daily Clean» mode. To switch
to other modes, successively press the on/off button. If you wish to
turn off your toothbrush from e.g. «Sensitive» mode, push and hold
down the on/off button until the motor stops.
Helping protect your teeth and gums from hard brushing, your
toothbrush has a pressure control feature installed. If too much
pressure is applied, the red pressure sensor light (b) will light up,
reminding you to reduce pressure (picture 4) (depending on model).
In addition the movement of the brush head will continue but its
pulsation will stop and you will also hear a different sound while
brushing. Periodically check the operation of the pressure sensor by
pressing lightly on the brush head during use.
A short stuttering sound at 30-second intervals reminds you to brush
equally all four quadrants of your mouth (picture 3). A long stuttering
sound indicates the end of the professionally recommended 2-minute
brushing time. The elapsed brushing time is memorised even when
the handle is briefly switched off during brushing. When pausing
longer than 30 seconds the timer resets.
