Q&A

• Can I use the brush on implants or teeth that have undergone dental work?

• SOLADEY RHYTHM2 can be used safely on teeth with fillings and crowns. If you have implants, please consult your doctor before use. Make sure to select a brush that best matches your teeth and gums and brush with care.

• Is the brush body heavy?

• The SOLADEY RHYTHM2's body weighs around 50g (without the battery), which is about the same as an egg. Although the brush uses sonic vibrations to clean teeth, it is still exceptionally easy to hold and maneuver inside the mouth.

• How do I replace the brush head?

• [To remove] Hold the brush and body horizontally and pull to the sides.
  [To attach] Firmly press the brush into the body until it clicks.

• How bright should the room be?

• Normal lighting is sufficient to power the brush.There should be enough light to see your reflection in the mirror or to use a solar-powered calculator.

• What is the main difference between conventional electric toothbrushes and SOLADEY RHYTHM2?

• SOLADEY RHYTHM2's greatest feature is its dual chemical and physical cleaning actions, which combine the power of electrons and sonic vibrations into a single brush.The sonic vibrations support the electrons' chemical properties to deliver exceptional plaque removal performance. What is more, there are two modes of vibration, which allow even first-time electric brush users the opportunity to confidently experience the brush's gentle sonic waves.

• Can children use the SOLADEY RHYTHM2 brush as well?

• Children capable of brushing their own teeth (around age 10) should have no trouble using the brush. We offer a selection of spare brushes for children that you can choose from. Don't forget to check if your child missed a spot when brushing!

• How do I use SOLADEY RHYTHM2?

• ① After inserting the battery, make sure the cover is securely closed.
  ②With brush attached, wet the bristles and semiconductor.
  ③Switch the brush on and gently clean your teeth, with the added support of the sonic vibrations.
  ●Make sure you are touching the stainless steel plate when holding the brush. Firmly press the bristles against the surface of your teeth while gently brushing.
  You can easily switch between vibration modes until you find the one you like.

• Can I use the brush if I have a pacemaker or defibrillator?

• Please do not use the brush as it carries a weak current that may interfere with these devices.

• Can I use it with toothpaste?

• The brush's chemical action is activated even when brushing with water alone. However, toothpaste adds to the cleaning effects. If you do use toothpaste, please make sure to remove the brush from the body after use and carefully rinse it as some toothpaste may still be stuck to the brush. Make sure to avoid toothpastes containing coarse abrasive agents as they may damage your teeth's enamel.

• How often should I change the battery?

• If you brush for around 2 minutes per session, you should be able to get about 120 uses out of the battery. If the vibrations begin to get weaker, it is time to change the battery. The brush takes one AAA alkaline dry-cell battery.
  ●Manganese and rechargeable batteries may not be able to deliver the desired effects.

• How often should I change the brush head?

• We recommend replacing your brush every one to two months. If the bristles begin to fray, it is time to change your brush head. Our spare brushes come in sets of 4 at 1,000 to 1,200 yen (without tax).
