I purchased my first Oral B toothbrush several years ago and have never gone back to a manual brush since. Since using Oral B, my overall dental health has improved greatly. Now all four of us all have our own Oral B electric toothbrushes and that's all we intend to use.
There are many Oral B electric brushes to choose from. These range from the more basic and less expensive to the more powerful costing a few hundred. Each one does a great job it just depends which one suits.
I am now using the new Oral B 9000.
This seems to be one of the higher end models and it's easy to see why when you read all the specifications and what this brush does.
