2 If you press the brush too hard against your
gums, you will feel and hear a click when the
brush head flexes backwards.As soon as you
reduce the pressure, the brush will return to
its normal position.
This will probably happen regularly when you first
start using the brush, but after some time you will
have discovered the optimal brushing pressure,
and the brush will flex backwards less often.
Tip: If plaque is removed properly, the gums will
have a pink colour and firmly surround the teeth.
Healthy gums do not bleed when you eat or brush
your teeth (see also the section 'taking optimal care
of your teeth')
If, nevertheless, your gums bleed slightly the first few
times you use the brush, this bleeding will generally
stop after a few days. If it does not, consult your
dentist or dental hygienist.
Minimum brushing time: 2 minutes
In general, 2 minutes will be enough to clean your
teeth properly.Therefore the brush is equipped
with a red pilot light that will blink for 40 seconds
when you have been brushing for 2 minutes (only
types HX 2550 and HX 2540).
Naturally, you can also brush longer than 2
minutes.
After brushing
1 Let the toothbrush run while you rinse the
brush head under the tap. Use lukewarm
water (max. 60°C).
