Manual brushing obviously works. When you brush your teeth with standard toothbrushes, you can leave plaque and gingivitis behind. But with an electric toothbrush like the Philips One Sonicare Toothbrush, you will ensure your teeth are completely clean. Thanks to the micro-vibrations used during brushing and the soft nylon conical bristles that gently polish the teeth, you will understand what real tooth cleaning should be like. It warns you to change the area you brush at 30-second intervals and sends a different warning stating that you need to complete the process after a total brushing time of 2 minutes. Its rechargeable battery lasts up to 30 days. Thus, you do not need to take the charger with you on your travels. Philips One Sonicare Toothbrush, which has a minimalist and stylish design, can be purchased in three different colors.
