EDEL WHITE SONIC GENERATION WINNER Manuel D'utilisation page 28

It is recommended to work by quadrants or arch, making sure to brush
tongue-side, cheek-side and tops of the teeth.
After 30-40 sec., the toothbrush signals to change the quadrant by
a short interruption in its vibration. Repeat this cleaning process for
each quadrant. When the time has run out the device automatically
deactivates. If needed, it is possible to continue brushing by simply
reactivating the device.
Important: Do not exert pressure on the toothbrush. Gentle surface
contact along the tooth and gums will lead to better cleaning results
and maintain the health of your teeth and your gum line.
Your Sonic Generation WINNER is also safe to use on: braces,
®
implants and dental restorations (fillings, crowns, veneers).

hygienic reasons. Brush heads wear out sooner when used on braces.
For more usage information, ask your dentist, dental hygienist or
assistant during your dental appointment how to use your sonic
toothbrush.
