Ultimately, all of the brushes will provide a very good clean to the teeth and gums if used correctly.
Sadly, this is not the case, but many products do last for a reasonable amount of time and we have read many stories of users enjoying 5+ years from their Oral-B electric toothbrush.Several other people remarked that they were happy to find that the toothbrush is compatible with Oral-B toothbrush heads across the range – good to know if you’ve got a stash of heads waiting to be used (you can still make use of them with your new toothbrush).
The built-in pressure control technology senses your brushing technique and alerts you on your speed and pressure, helping protect your gums. The sleek toothbrush has three unique brushing modes that help to remove plaque, offer a superior clean and delicately whiten to achieve healthy pearly whites. The grippy and slim Smart 4 4000 is a solid brush. It has the features dentists recommend, cleans the teeth well and lasts 2 weeks on a full charge. Finally, many people commented on the quality of the battery life; mentioning that it lasted 2 weeks on one charge if being used by a single person, or 1 week if being used by a couple. Plenty of time for most trips away. Oral B claim that the brush has been clinically proven to remove twice as much plaque as a manual brush, using it’s 3D technology, which pulses, rotates and oscillates simultaneously up to 40,000 times per minute.
