The Oral-B Pro 2 2500 and Philips Sonicare are both good electric toothbrushes. The Oral-B Pro 2500 is the one with a larger range of features. Both the electric toothbrushes come with Quadpacer 2 minute timers. This is an on handle timer that “buzzes” every 30 seconds reminding you to change area of your mouth. This feature is essential for any good electric toothbrush.
Pressing too firmly with a toothbrush can lead to gum recession and sensitivity. To prevent this from happening the Oral-B Pro 2 2500 has a visible pressure sensor that flashes red when you press too hard. The Philips Sonicare HX3214 is completely missing this feature.
The Oral-B Pro 2 2500 also comes with 3 cleaning modes compared to the solitary one cleaning mode of the Philips Sonicare. The Oral-B Pro 2 2500 as standard comes with:
*Daily Clean Mode
*Gum Care Mode
The Philips Sonicare comes with the regular clean mode and an easy start programme. The easy start programme ramps up the intensity of the electric toothbrush over the first 2 weeks of using the brush. People transferring from using a manual toothbrush may find this useful to get used to the feeling of a sonic electric toothbrush. After that period, the easy start programme becomes useless.
Travelling with an electric toothbrush can be tricky as the handle needs to be protected from heavy impacts. The Oral-B Pro 2 2500 comes with a travel case to protect it. The travel case although basic in design is a godsend as it protects the Oral-B Pro 2 2500 electric toothbrush handle and two brush heads. The Philips Sonicare HX3214/01 CleanCare + does not come with a travel case.
This is one area that the Philips Sonicare really does shine, the battery life is almost double that of the Oral-B Pro 2 2500. The battery life of the Philips Sonicare HX3214 is 10 days whereas the Oral-B Pro 2500 is sitting at a measly 5 days of charge.
Although the Philips Sonicare has a better battery life, it is outclassed by the Oral-B Pro 2500 in all other departments. The Oral-B comes with many more features that the Philips Sonicare simply does not have. Therefore the better electric toothbrush under £40 is the Oral-B Pro 2 2500.
After comparing lots of electric toothbrushes, it turns out that Oral-B offers more features for your money. This is a general trend and with all trends there are exceptions. Notably in the US for electric toothbrushes under $50 there is virtually no difference between the two brands.
As a rule of thumb, you will tend to get more bang for your buck with Oral-B. The only benefit to the Sonicare is that Sonicare is licensed by Sonic the Hedgehog himself and will clean your teeth lickety split, Oral-B is funded not so publicly by Cliffy-B and we all know how good at promises that guy is. But then again, if you use the Oral-B you can tell your friends "Yeah, I do oral-" and then get interrupted by a convenient distraction before you can finish. They'll know you'll have the most exquiste of tastes!
