Yes, numerous clinical studies have shown that electric toothbrushes remove plaque more effectively than manual toothbrushes. According to the American Dental Association, electric toothbrushes can remove up to 21% more plaque and reduce the risk of gingivitis by 11% compared to manual brushes. However, proper brushing technique remains essential, regardless of the type of toothbrush used.

Sonic technology (used by Philips Sonicare, Quip, and Snow) vibrates the brush head at very high frequencies (up to 62,000 movements per minute), creating micro-bubbles that help clean between teeth and along the gum line. Oscillating-rotating-pulsating technology (used by Oral-B) rotates the round brush head back and forth while pulsating, to clean each tooth individually. Both technologies are effective but offer different brushing sensations.

It is generally recommended to replace the head of your electric toothbrush every 3 months, as with a manual toothbrush. However, if you notice that the bristles are worn or flattened before this period, it is better to replace it sooner. Some high-end models have an indicator that alerts you when it's time to change the brush head, usually by a change in bristle color or a notification on the connected app.

Yes, there are electric toothbrushes specifically designed for children. They are generally smaller, have softer bristles, and attractive designs. Some models even offer fun apps that encourage children to brush their teeth correctly and for the recommended time. It is advisable to introduce an electric toothbrush from the age of 3, always under adult supervision.

Yes, most modern electric toothbrushes have a "sensitive" mode specifically designed for sensitive teeth and gums. These modes use less powerful vibrations or rotations. Additionally, pressure sensors on many models prevent pressing too hard, which is particularly beneficial for people with gum issues. It is also recommended to choose brush heads with extra-soft bristles in these cases.
