When using the Bluetooth connectivity, the app will show the cleaning mode. I will explain the connectivity option in more detail shortly. You can bring the cost down further if you were to share it with other members of your household. All you need do is invest in extra brush heads. The idea behind this connectivity is to essentially be a little like having a dentist or hygienist looking over your shoulder saying good, bad, brush for longer, you missed a bit. It is about education for better cleaning rather than telling you that you have got it all wrong. 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. Up to 100% more plaque removal and gently whitens your teeth starting from day 1 by removing surface stains

You see, applying too much pressure when brushing is a big issue and it causes more damage than you might think. Excessive pressure can damage the gums and cause wear on your teeth. A brush need only skim the surface of the tooth and gums. So, the brush reduces the power to protect your teeth. Brushing for the full 2 minutes is very important, but just as important if not more so is the right technique. Make sure you learn how to clean your teeth properly. Each of the 3 cleaning modes work slightly differently, with differing levels of oscillations, rotations and pulsations to achieve different cleaning effects on the teeth. The very nature of being an electronic item with moving parts does indeed make the brush susceptible to failure. However, the reliability of Oral-B products tend to be very good.When you brush, sensors within the brush detect if you are applying too much force to your teeth. When it detects this, it activates the pressure sensor. I think this is a big oversight and even if it meant a few extra pounds being added to the price, I think it would have been a worthwhile addition.

Some Sonicare and Colgate models do actually achieve up to 3 weeks, but Oral-B are now much much closer in their capabilities. If you are particularly interested in the feature set of the Smart 4 4000, the Oral-B Teenhas identical technical specs, but can be snapped up cheaper. The only differences are the design and box contents.For 99.9% of users there will be years of hassle free brushing, but should you be one of the 0.01% where inevitably something does go wrong, Oral-B do not leave you high and dry.
