Review (5/5): Very Pleased
This toothbrush was an upgrade from a less-expensive Oral-B model that I used for several years before it finally quit on me. I'm very pleased with this new purchase.
The Oral-B 4000 has much more power than my old toothbrush and gives a deeper clean. My teeth feel cleaner after using this brush, and though I still need to floss I can tell that this brush is doing a more thorough job of cleaning between my teeth. My teeth look whiter and my gums look healthier. I also think the design helps me do a better job of cleaning my back teeth--my jaw is small and there's not a lot of space around my back molars. This brush helps me clean the back teeth very easily, though. I've found the beeps that help you time your brushing are very helpful, and I like having the ability to switch modes. One charge lasts better than a week--nice if you're taking this on trips.
A few minor cons--this brush is heavier than the old one I was using. Not so much that I didn't get used to it quickly, but enough that I noticed. It's got more power, but it's also louder. I also think the pressure indicator is a little awkwardly placed. I've seen it--I think--when I've triggered it most of the time, but the location makes me wonder if I'm missing it sometimes.
The only feature the 5000 has that this brush doesn't is the wireless display screen. I'm not sure what that does, but after using this model I can't see the screen being necessary. I'm very pleased with this toothbrush and hope that it lasts as long as my previous Oral-B toothbrush did.
