A smaller, but relevant difference relating to the cleaning modes is that the motor in the Pro 2 2000 is a bit more powerful and actually offers more movements than the Pro 600. 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.

It does not mean the brush will actually clean the teeth better. In fact, both have the same motor inside and the same cleaning modes. This is because (if you were not already aware) it is very common for electric toothbrushes, particularly Oral-B models, to sell at around 50% less than retail price. The Pro 3 3900 has 3 cleaning modes (Daily Clean, Sensitive & Whitening) compared to the 2 modes (Daily Clean & Sensitive) of the Pro 2 2900. The 3000 is available in a few different variants, meaning different handle colours and brush heads included. However, typically you will get just 1 brush head in the box. That is usually the CrossAction head, like that supplied with the Pro 2. In the sections below we compare Oral-B brushes that are close to each other in price and features. Model by model comparison Pro 600 vs Pro 2 2000The Oral-B Pro 2 2500 looks like an expensive electric toothbrush and feels solid in the hand. It features a slimline body, which is easy to grip. Although if you do suffer from arthritis of the hand, it may be on the too thin side. Aside from this the two brushes feel the same in hand, weigh the same and have the same warranty, they both come with a charging stand and 1 brush head in the box. Pro 2 2000 vs Pro 3 3000 Hopefully, this gives you a good overview of where various brushes fit in in terms of price and features, but if not please leave a comment or question. Both do a job and give a home to brush heads, but the 9000 is a neater and more desirable solution. The Oral-B Pro 3000 have these two cleaning modes and an additional one which is sensitive. Although cleaning modes are in the most part irrelevant, the sensitive mode works by reducing the power of the electric toothbrush from 8,800 oscillations and 40,000 pulsations down to 6,500 oscillations and 30,000 pulsations. This can be particularly useful for people with sensitive teeth especially when used in conjunction with the sensitive brush head. The Oral-B Pro 3000 also comes with another extra brush head which is a nice addition.

Where the large rubber grip on the 2500 provides grip, this is now limited to the power button on the 3500.The Oral-B Pro 2 2500 Electric Toothbrush comes with a travel case where you can store the electric toothbrush handle and two electric toothbrush heads. It is a pretty simple construction however it has some neat design features.
