This feature protects your gums by signalling you if you're brushing too hard. The 360° pressure sensor turns red and automatically slows brush speed. iO Gentle Care: the gentlest iO Refill for a smooth brushing experience. Cushioning outer ring with thinner filaments to protect gums, high density of extra soft bristles for a gentle clean This is a fantastic price given the cleaning performance and dentist recommended features it boasts. It really is a must buy. But, at 2+ weeks it falls short of the industry average which is really at 3-4 weeks. By no means is this a deal breaker when considering the Pro 3.

You need to press the power button 3 times, each and every time you use it, if you want whitening mode.

Sensitive is also a great choice for first time electric toothbrush users. It makes for a more pleasing introduction to the increased power such brushes offer. Oral-B PRO 3 and brush heads are designed to work together for an optimal clean. From CrossAction to Precision Clean, to 3D White, to Floss Action, Oral-B brush heads deliver a superior clean vs. a manual toothbrush. A softer, dimpled texture to the plastic body also replaces the raised lines that have adorned the rear of brush handles such as the Smart 4. While Oral-B has partnered with schemes such as TerraCycle in some countries, it does not yet have its own recycling scheme for used brush heads or faulty products. We don’t have an extensive list of must-have features, but there are a few that our in-house dentists feel are really worthwhile: a 2 minute timer, a pacer and a pressure sensor. These are included in all but the cheapest of brushes these days. The 2 minute timer and pacer help you clean your teeth evenly

The pacer momentarily pauses the brushing action every 30 seconds to tell you to move on to the next part of the mouth. After 2 minutes the alert changes slightly to tell you that you have brushed for long enough. Scrubbing and using lots of force as you brush will damage the teeth and gums over the long term. Oral-B has for many years built pressure sensors into their toothbrushes and the Pro 3 is no exception. When low, the battery notification LED will flash red and you may notice the motor slow. A full recharge takes up to 12 hours. The battery LED will flash green whilst charging, before turning off once complete.

Oral-B's round head surrounds each tooth for cleaner teeth and healthier gums, removing up to 100% more plaque vs. a manual toothbrush If you are sensitive and don’t like such a powerful clean, the softer Sensi UltraThin brush head and the lower powered cleaning mode can be beneficial.

Included in the box is a single brush head. Oral-B’s oscillating-rotating brush heads are smaller than the sonic ones from the likes of Sonicare and can feel quite aggressive in comparison. They do make it easy to reach the tightest of spaces, though. Daily Clean is my preference and the one I recommend most people use. But, the option of Sensitive is great for those who want to enjoy a less intense cleaning action, or for those days your teeth or gums might feel a little more tender. DEEP CLEANING AND HEALTHIER GUMS with 360 ̊ GUM PRESSURE CONTROL that visibly alerts you if you brush too hard Unlike some brushes, the Pro 3 3500 doesn’t power off automatically.
