Electric toothbrushes are clinically proven to be superior to manual toothbrushes, providing benefits in removing more plaque for cleaner teeth and healthier gums. Oral-Belectric toothbrushes remove up to 100% more plaque than a regular manual brush, which is why they are recommended by UK dentists and hygienists. Oral-B electric rechargeable toothbrushes (from Pro 600 model upwards) also whiten teeth starting from day one by removing surface stains. Electric toothbrushes are suitable from ages 3+, with specific kids electric toothbrush models available, and are gentle on gums and suitable for sensitive teeth. Electric rechargeable toothbrushes come with replacement toothbrush heads, which should be replaced every three months. It's common knowledge these days, but everyone is recommended to spend two full minutes cleaning their teeth. As a nod to this, the Oral-B Pro 2 2500 provides an audible warning via a slight pause in the brush motor every 30 seconds. This acts as a cue during brushing for you to change your focus between the four different quadrants in your gob: upper right, upper left, lower right and lower left. It’s a nice touch that works really well. The first thing we should note about the Pro 2 2500’s cleaning performance is its “Sensitive mode” which can be accessed by double pressing the on button. This actions the motor to deliver fewer movements per second to the brush head, offering a far less intensive brushing experience. This is ideal if you have sensitive teeth and gums, or would like to prevent your gum line from receding. Another neat design feature is the rear-mounted pressure sensor, which illuminates red to tell you you’re applying too much force and pressure to the teeth during cleaning. Acting as a visual indicator, it really helps to make you more aware of any bad brushing habits you've fallen into thus reducing the chance of you doing any damage to the teeth. It’s a simple yet clever design detail that works exceptionally well and helps you to brush your teeth the way your dentist would want.
