As the name implies this mode is more gentle. It is designed to offer a softer, but thorough clean. It helps those with sore or inflamed gums, but reducing the number of movements in the brush head, making for a more comfortable brushing experience, until the sensitivity has gone or reduced. This mode is great if you are suffering from gum disease. From the time of the 1912 renumbering, a system was adopted for new locomotives where the second digit indicated the broad type of locomotive. For example, express passenger locomotives had x0xx numbers and large mixed traffic tender locomotives were x9xx. When a class numbered more than 100 locos, rather than continue the numbers consecutively the second digit remained constant (e.g. 4900 Class included 4900-4999, 5900-5999, and 6900 onwards).

To look at the 2 toothbrushes there is a great deal of similarity, the biggest noticeable difference is that the Smart 4 4000 has a white rubber grip on the front of the handle, compared to the dark blue of the Pro 2.

The next big difference is the battery life. The Pro 2 2000 has over twice the usage time. The Pro 600 will operate for 28 minutes, which is 7 days of cleaning based on one user. However the Pro 2 will last for 66 minutes which is 16 days of usage time. The Pro 3 3000 has a slightly revised design. It looks a little cleaner. Unlike the 2000, it does not have a rubber grip that runs the length of the brush handle. Instead, the only grip on the front is the panel that contains the power button.

First there is the number the class is known by (not necessarily in this range) linked to the appropriate article or article section Bristles of the brush head should just skim the tooth surfaces. You don’t need to brush hard to clean your teeth effectively. Davies, Ken (April 1993).

A fourth series of 25 locomotives appeared during the years 1911 to 1913 (Swindon Lots 185, 189 and 192). These were numbered 2931–55 and named after famous Courts (i.e. mansions). They were all built with superheaters and there were detailed differences between the boilers used on different lots. [13] They were all withdrawn between 1948 and 1953.

Being built during World War II, wartime shortages of lightweight metals resulted in ordinary metals being used for their construction. This resulted in the class being the heaviest 4-8-4s ever built. They outweighed their nearest rivals by over 2,000 pounds. They have Timken roller bearings on all axles. [1] Between 1946 and 1948, they were then approved for 110 mph speeds with the Santa Fe's express passenger trains after being fitted with Timken roller bearing tandem side-rods, up from 100-mph when delivered with its original side-rods.

Below, is a list of models we have compared to one another, plus some that we have compared to their Sonicare equivalents.

There is no battery in the case, to charge the brush and anything connected via the USB cable the case has to be connected to mains power. The various additional modes on different price point models (for example, the sensitive mode etc) involve to some extent varying the speed. None of these modes have a more powerful cleaning action than the Daily Clean mode, but do offer other benefits to those users who want or need them. Of course, in the more expensive model ranges, there are also some “connectivity” options, which enable the user to connect their toothbrush to their smart phone or an electronic monitor. For the majority of people, myself included the Oral-B Pro 3 3500 is the toothbrush to go for. It offers a balance of cleaning performance and features at a price most will find affordable. Rebuilt in 2019 from GWR 4900 Class 4942 Maindy Hall.

Yes, you can buy new brush heads etc from the app, but the presentation of data and logging it all within the app can give you an overview of just how good or poor your oral care habits are.
