Choosing the best electric toothbrush isn't that easy with the vast array of products available on the market, so do some careful research and make some comparisons before choosing the best electric toothbrush for your needs.
Here are some things that you need to consider when looking for the best electric toothbrush:
Do you want a battery or mains operated (rechargeable) toothbrush?
Do you want a gentle clean or a robust scrub?
What brush action would you prefer and do you want a built in timer?
When you've answered the above questions to your own satisfaction, make yourself a chart or spreadsheet with your criteria down the side, e.g.
Rechargeable Battery
Battery Life
Battery Indicator
Timer
Brush Action
Cleaning Modes
Number of brushes included
Storage for spare brushes
Cost of the unit
Cost of replacement brushes
Warranty
Customer Ratings
Other Features
Now go to an online store such as Amazon and search for electric toothbrushes. Choose three or four which are in the price range that you want to pay and put the names across the top of your chart. Now read all the available information and fill in your chart.
Decide which features are the most important to you. It's a good idea to ignore the price of the unit at this stage, just concentrate on the tooth brushing aspects. On your chart highlight the best result in each category. For example if Brush No. 1 has a 14 day battery life and that is the best of the ones that you have chosen, highlight that box on your chart. You should end up with a highlighted box for each of your criteria and one of the toothbrushes will have more highlighted criteria than the others. This should give you a good idea of which is the best electric toothbrush for you.
When you've decided which toothbrush you want to buy, it's best to shop around both offline and online for the best pricing deal as prices can vary tremendously for the same product. You may even find that some stockists have "specials" which include extra spare brushes.
Check out online comparison sites which may have done all the hard work for you, including finding the best prices out there or you could subscribe to a technical investigation type magazine such as Which? which does in-depth research into all sorts of electronic products and which will help you identify the best electronic toothbrush.
