Slide the brush head onto the toothbrush handle. There should be a slight gap between the base of the brush head and the handle. This is to allow freedom of movement in the brush head for the most efficient sonic cleaning action.

Wet the bristles and apply a small amount of toothpaste.

1. With toothbrush off (to avoid loss of toothpaste), place the bristles against your teeth at a 45° angle toward the gum line

2. Press the power button on the toothbrush handle to the desired mode. [ Mode 1- Power on/Clean, Mode 2- Whiten, Mode 3- Polish, Mode 4- Gum Care ]

3. Apply light pressure and gently move the brush slowly across your teeth contacting all enamel surfaces with small up and down and circular motions. Allow the sonic motion to do the cleaning- do not move the brush around rapidly or apply too much pressure.

4. Divide your mouth into 4 sections- upper right, lower right, upper left, lower left (or upper front, lower front, upper inside, lower inside). Brush 1 section at a time. The toothbrush will pulsate quickly at 30 second intervals to inform you when to move to the next section.

5. The toothbrush will automatically turn off at 2 minutes alerting you that the brushing session is complete.

6. Rinse the brush head and handle under clean running water and wipe dry. Place the toothbrush back in the charger.


To help kill the bacteria that causes bad breath, use the tongue cleaner on the back of the brush head. Add more toothpaste if needed and use the toothbrush on Mode 1 (Clean). Brush for 30 seconds contacting as much of your tongue as possible.
