Before First Use

Before using the Sonicare toothbrush for the first time, attach the brush head and charge the handle.

A full initial charge may take up to 24 hours. The toothbrush can be used before it reaches a full charge.

How to Attach the Brush Head

1. Remove the toothbrush handle and brush head from the packaging.
2. Align the brush head so its bristles face the same direction as the front of the handle.

A small visible gap between the brush head and the handle is normal.

Initial Charging

1. Connect the USB charger to a compatible power adapter.
2. Plug the adapter into a wall outlet.
3. Place the toothbrush handle on the charger.
4. Check the battery indicator lights.

The handle emits two beeps when placed correctly for charging.

The battery lights flash while charging.

How to Use the Philips Sonicare Toothbrush

The toothbrush uses a powered brush head and a timed brushing cycle.

During brushing, gentle pressure should be applied while the brush head moves across the teeth.

Step-by-Step Brushing Instructions

1. Wet the toothbrush bristles.
2. Apply a small amount of toothpaste.
3. Place the bristles against the teeth at approximately a 45-degree angle.
4. Position the bristles so they reach the gumline or slightly beneath it.
5. Keep the center of the brush head in contact with the teeth.
6. Press the Power On/Off button to start brushing.
7. Move the brush slowly with small back-and-forth movements.
8. Allow the bristles to reach between the teeth.
9. Continue following the timed brushing intervals.
10. Move to the next section of the mouth when the BrushPacer signals.
11. For the inside surfaces of the front teeth, tilt the handle into a semi-upright position.
12. Use several overlapping vertical strokes on each front tooth.
13. Continue brushing until the selected mode finishes.
14. Allow the toothbrush to switch off automatically.

The bristles should flare slightly during brushing.

Do not scrub the teeth with the same force or movement used with a manual toothbrush.

Correct Brushing Pressure

Apply only gentle pressure.

If excessive pressure is detected:

• The handle changes its vibration.
• The brushing sound changes.
• The light ring at the bottom of the handle flashes purple.

Reduce pressure until the warning stops.

Using the Toothbrush for the First Time

New Sonicare users may notice stronger vibration compared with a manual toothbrush.

Philips recommends starting with a lower intensity setting for the first one to two weeks before moving to a higher setting.

Brushing Teeth with Braces or Dental Restorations

The toothbrush can be used on braces and dental restorations, including:

• Fillings.
• Crowns.
• Veneers.

Dental restorations must be properly attached and not compromised.

Brush heads may wear out sooner when used with braces.

Brushing Modes and Settings

The Philips Sonicare 6400–7400 family includes up to four brushing modes.

The modes available depend on the toothbrush configuration.

It uses a two-minute brushing cycle, with Low as the recommended intensity.

Brush each of the six sections for 20 seconds.

White Mode

White mode combines plaque removal with additional brushing for surface stains.

The cycle lasts two minutes and 40 seconds.

1. Brush the six main mouth sections for 20 seconds each.
2. Continue brushing the two additional sections for 20 seconds each.

The recommended intensity is High.

When the brush head replacement indicator turns amber, the brush head should be replaced.

The reminder only operates with compatible Philips Sonicare smart brush heads.

The replacement reminder is enabled by default on compatible smart brush heads.

Indicator Lights and Troubleshooting

The Sonicare toothbrush communicates operating conditions through colored lights, sound signals, and changes in vibration.

Indicator and Troubleshooting Guide

Why Is the Sonicare Light Ring Flashing Purple?

The purple light indicates that too much pressure is being applied during brushing.

The handle also changes its sound and vibration.

Reduce brushing pressure until the warning stops.

Why Is the Toothbrush Flashing Amber?

An amber battery light indicates either low or empty battery status.

• Three beeps after brushing indicate a low battery.
• Two sets of five beeps indicate an empty battery.

Place the toothbrush on the charger.

An amber light at the brush head replacement indicator has a different meaning: the brush head needs replacement.

Why Does the Sonicare Toothbrush Stop Automatically?

The SmarTimer switches off the toothbrush when the selected brushing cycle is complete.

The duration depends on the selected mode.

Clean and Sensitive run for two minutes, White for two minutes and 40 seconds, and Gum Health for three minutes and 20 seconds.

Why Is the Toothbrush Vibration Stronger Than Expected?

New Sonicare users may notice stronger vibration than with a manual toothbrush.

Philips recommends using a lower intensity setting for the first one to two weeks.

The intensity can be increased after becoming familiar with the toothbrush.

Why Is BrushSync Not Tracking the Brush Head?

BrushSync replacement tracking requires a compatible Philips Sonicare smart brush head.

Compatible heads have the BrushSync symbol.

The replacement reminder function is available only when a compatible smart brush head is attached.

Why Is Brushing Data Not Updating in the App?

The Sonicare app requires Bluetooth connectivity to exchange brushing data.

For synchronization:

1. Turn on Bluetooth on the phone.
2. Activate the toothbrush by picking it up.
3. Open the Sonicare app.
4. Keep the phone close to the toothbrush.
5. Connect the toothbrush to the app.

Philips recommends manually syncing approximately every two weeks when automatic synchronization is not used.
