Overview

Dear customer,

Congratulations on the purchase of your TB 7930 sonic electric toothbrush.

Read the following user notes carefully to ensure you can enjoy your quality product from Grundig for many years to come.

Special features

• Two different speed settings: "High" (fast), "Low" (slow), and a "Massage" setting.
• 2-minute timer: after 2 minutes the appliance switches off for approx. 3 seconds and then starts again. After five timer cycles the appliance switches off automatically.
• Two brush heads and three additional attachments for special cleaning (tongue cleaner, gum massage attachment, and brush for gaps between the teeth).

Using in the bathroom

Your toothbrush has a waterproof handle, is electrically safe, and can be used in the bathroom without hesitation.

Oral hygiene

Careful oral hygiene is essential for maintaining healthy, beautiful teeth.

Daily intensive oral hygiene can prevent tooth decay, gum disease, inflammation of the gums, and bad breath.

Cleaning

The sonic electric toothbrush removes plaque more precisely and effectively than conventional manual toothbrushes due to the high speed of the brushing movements on the surface of the teeth.

Discolouration of the teeth from coffee, tea or tobacco can be removed in a natural way. Teeth, tongue and gums can be cleaned and cared for carefully.

OVERVIEW

Intensity

You can set the intensity of the cleaning at 3 levels (high, low, massage).

The extensive accessories provide you with excellent conditions for personal oral hygiene.

Brushing time

The recommended time for brushing is 2 minutes. The timer then stops the function automatically.

Accessories

1 Tongue cleaner

The tongue cleaner freshens your breath as it removes the bacteria from the tongue which create bad breath. You can use it every day before or after brushing your teeth and also with mouthwash.

Set the appliance to a low speed, so you have more control over the cleaning.

2 Interdental cleaner

The interdental cleaner cleans effectively between the teeth and helps to improve oral hygiene. This should be done before you clean your teeth.

Set the appliance to a low speed, so you have more control over the cleaning.

3 Gum massage attachment

The gum massage attachment stimulates the gums with sonic vibrations.

It is best to use this attachment after brushing your teeth.

Note

■ The rounded Dupont® bristles on the brush head, tongue cleaner and the interdental cleaner enable you to clean your teeth perfectly and also protect your gums!

Notes

■ The mounting pin on the appliance is designed in a way that prevents you from attaching a new attachment incorrectly. ■ Replace the brush head when the bristles become bent and distorted. We recommend you to do this every 3 months.

DENTAL CARE

General information

1 Brush your teeth:

• in the morning after breakfast
• after mealtimes - and after snacking
• in the evening before bed for at least 2 minutes.

2 Rinse the brush under running water for a few seconds until it is thoroughly moist.

Note

■ Rinse your mouth out with water before brushing your teeth. 3 Put your regular toothpaste on the brush.

Brushing your teeth – step by step

1 Before switching on, position the bristles (medium) of the brush head at an angle of 45° onto the gum line so that the longer bristles reach between the teeth. 2 Tilt the handle slightly so that the bristles are resting at an angle on the gum line.

Note

Cleaning the area between the teeth and gums is extremely important. 3 Hold the handle loosely in your fingers and switch the appliance on with »◀«.

DENTAL CARE

4 Gently move the vibrating brush head in small circles to allow the longer bristles to get to the gaps between the teeth. After a few seconds, move to the next section and repeat the circular movements again for a few seconds.

Notes

Continue in the same way for all the teeth within the 2 minutes to thoroughly remove plaque.

The toothbrush works best if you apply slight pressure when brushing and continue with the circular movements at the same time.

The tilted brush head and the narrow neck make it easier to reach the molars at the back and the surface of the teeth inside the mouth. Hold the toothbrush so that you have as much brush contact to the teeth as possible.

5 To ensure that all your teeth are cleaned evenly, the mouth can be divided into six sections:

1	Exterior upper jaw
2	Chewing surface upper jaw
3	Interior upper jaw
4	Exterior lower jaw
5	Chewing surface lower jaw
6	Interior lower jaw

6 Clean the tongue with the toothbrush switched on or off and using the tongue cleaner provided. Apply slight pressure on the brush and scrape it forwards from the back - then rinse out.

DENTAL CARE

Note

In some cases you might experience a tickling or tingling sensation when using an electric sonic toothbrush for the first time. This sensation gradually subsides once you have got used to the sonic toothbrush. 7 Rinse your mouth out with water after brushing. 8 Rinse the bristles under running water after brushing to remove any remaining toothpaste. Dry the bristles. Leave the toothbrush to dry for a few seconds.

Notes

We recommend using dental floss before you brush your teeth. We also recommend using Meridol mouth wash.
