Philips Sonicare 3100 Series Sonic Electric Toothbrush (Dual Pack) with Pressure Sensor and BrushSync Replacement Reminder, HX3675/13, White

Product Information

Despite claiming Sonicare win this category, Oral-B tends to offer more features on cheaper brush handles. More cleaning modes, a pressure sensor and Bluetooth connectivity on models that are cheaper than Sonicare, allowing those with a restricted budget to get more for their money. Too much pressure can cause wear on the teeth and gums. Long term, this can result in irreversible damage. The 3100’s built-in pressure sensor can help you if you know you brush too hard. The exact way that this happens is not fully understood, but it is thought that very high frequencies cause liquids to move and create “hydrodynamic forces” which damage the plaque layer in hard to reach areas ( 1). This intense vibration agitates fluids that surround the teeth and can loosen and remove dental plaque in locations that are beyond the physical touch of the toothbrush. To have this effect the waves actually need to be working at a much higher speed, in the ultrasonic range, greater than 20,000 Hz.

Using them for more than 3 months can result in less effective and more abrasive brushing. This is because the bristles will have worn.

Getting kids to clean their teeth well is rarely easy, but a decent electric brush can help – and this one will make it fun, too. The interactive Bluetooth app puts the character Sparkly, who loves nothing more than cleaning his teeth, at the centre of the action on your device. Not only can kids mimic Sparkly cleaning his teeth in real time, focusing on different sections of their mouth, but they can gain rewards including food, accessories and new skills for him by cleaning as they should and for the required two minutes.The 3100 also has an EasyStart mode, which gradually increases the brushing intensity over the first 14 sessions to ease you in. The Sonicare 3100 is one of Philips’ entry-level Sonicare brushes, but in actual use you’d struggle to notice; the core technology works brilliantly and it’s compatible with all the brush heads. Philips sells it with a ProResults head attached, along with a USB charger.

So this is perhaps one of the most personally influenced categories on which to judge a toothbrush.Philips also produces a Sonicare for Kids brush aimed at younger children, along with the Philips One electric toothbrush, which delivers basic Sonicare tech inside a slimmer, cheaper brush.
