With the Lithium-ion battery, you get two weeks battery life compared to 7 days of the old Nickel Hydride battery. The battery flashes red when needs charging, green when it is charging and no flash when it full charged.
Apart from that, the carry case is also included with this new 3000 electric toothbrushes.
- 2 Cleaning modes: daily clean and sensitive

- Travel Case

2 Cleaning Modes
Compared to the Oral B 4 4000 smart that comes with 3 modes, with this toothbrush, you get only 2 cleaning modes: the daily clean and the sensitive mode. Daily clean mode is for people who have normal teeth and need more pressure to clean their teeth. The daily clean mode can be used with any brush head mainly the CrossAction to remove dental plaque on a daily basis.
The sensitive mode, on the other hand, is to be used with the sensitive brush head for cleaning sensitive teeth and gums. And the whitening mode is for people who want to polish their teeth or remove more plaque from their teeth giving them a more bright appearance.
In-Built Quadpacer Two Minute Timer
The 3 3000 like all other Oral B electric toothbrushes, this brush comes also with a built-in timer with a pacer that buzzes after every 30 seconds and double buzz when 2 minutes recommended brushing time is over.
The 30 seconds buzz alerts you to move from the area you are brushing to another area. Basically our mouth is divided into 4 quadrants, you spend 30 seconds brushing each area with the help of the buzzing quad pacer.
Visible Pressure Sensor
The 3 3000 also includes a visible pressure sensor located at the rear side of the handle. The sensor is there to help you not to over brush your teeth. Every time you press too firmly, it flashes red.
It is advised that you avoid brushing your teeth too hard as doing so may lead to wearing out of tooth enamel and hence tooth cavities, gums recession and sensitivity. The red flash on the pressure sensor will help achieve that by alerting you every time you brush too hard.
3D Cleaning Action
As you might have heard or read, the brush employs rotary technology: oscillating, rotating and pulsating. It is claimed that this technology cleans better than Philips Sonicare motion (https://www.cochrane.org/CD002281/ORAL_poweredelectric-toothbrushes-compared-to-manual-toothbrushes-for-maintaining-oral-health).
What you get with the 3 3000 like all other mid to high-end toothbrushes is a proper tooth to tooth cleaning. You guide the brush for a few seconds each to clean each tooth individually removing up to 100% plaque.
2 CrossAction Brush Head
You get two brush heads compared to the one that you get with the best selling 2 2500 electric toothbrush.
- CrossAction brush head: This is the small round head with angled bristles for cleaning both teeth and along the gum line. And the
- 3D White brush head: This brush head is for teeth whitening. It has a whitening cup on it for scrubbing teeth surface stains giving your teeth a whiter look compared to using the CrossAction head only
Cons:
- No Bluetooth connectivity, if you like this feature check the Smart 4 4000
- Like other Oral-B’s, this brush also does not switch off itself automatically after 2 minutes brushing time. You need to switch it off manually

Pro 3 3500 Review
The Oral B Pro 3 3500 electric toothbrush is more less the same as the 3000 . Like the 3000, this 3500 model includes:
- One CrossAction brush head – The 3500 as all other electric toothbrushes from this brand is compatible with most Oral B’s brush heads except io, pulsonic and sonic brush heads. This means that you can always buy any other brush head such as the 3D White, FlossAction, and Senstive head
- 3 cleaning modes (whitening, sensitive and dailyclean). This helps not only to brush your teeth daily but also to polish them with the whitening mode and use sensitive mode when you are teeth or gums are in pain
- 2 minute timer – This is the most admired feature in most electric toothbrushes as it helps you to brush your teeth at recommended denstist 2 minutes brushing time
- 14 day battery life- Like the 3 3000, the 3500 includes a Lithium battery which last up to 14 days after charging it. Avoid putting it on charger daily as it damages the battery making it not able to store the charge for long time. To charge it, the brush comes with the 2 pin UK shaver plug .
- 2 colour choice: white and black compared to 4 colour choice of 3000 (white, blue, pink and black)
- A travel case – This what makes the 3500 stand out from the 3000 model. A travelling case helps you to store your brush and 2 brush heads safe and free from bacteria while on journey.
Pro 3 3900 Review
If you looking for the best electric toothbrush for couples, Oral B Pro 3 3900 is one of the good option in the market today. Like The 2 2900, the 3900 comes with 2 sets of electric toothbrushes.
And what makes it stand out from the rest is the fact that instead of getting only one or two brush heads, the 3 3900 comes with 10 crossAction brush heads. And you get all these for under 100 pounds.
In terms of colour choice is that you can either get it in 2 black brushes or black and white or black and pink.
Apart from this there no travel case included 3 3900 when compared to the one set 3500 model.
Which is Better, Oral B Pro 3 3000 , 3500 or 3900?
Oral B Pro 3 3000 is cheaper than the 3500 and 3900 electric toothbrushes. This means that if you’re on a budget, the 3000 model may be a better option for you. However, if you want features such as multiple brush heads, then the 3900 model may be a better option for you.
