Rechargeable is best
Although this costs more than than battery operated varieties, you can recharge these toothbrushes from the AC adaptor that’s included. This means you don’t have to worry about changing batteries over time (which costs more in the long-run and isn’t good for the environment).
Choose a small head with oscillation movement
A small head will help clean those stubborn spots that are tricky to reach. We find that brushes that move in a back and forth oscillation movement are more effective than those with a simple circular motion. Steer clear of electric brushes that have a vibration function, but no movement.
Removable brushes – The ability to remove toothbrushes means that other people in your household can use the same unit (by attaching their own brush head). Make sure the brushes are different colours, so you can easily identify your own.
Even if you’re the only one using this technology, steer clear of units that don’t allow you to change brushes, as this means you have to replace the entire thing!
Timer – This is worth saying again, since not all electric brushes come with this feature, but it’s a handy addition that encourages people to brush for 2 minutes.
Speed – It helps if you can choose different speeds and pressures, depending on the sensitivity of your gums and teeth.
Indicator bristles – Some brushes feature bristles that slowly lose their colour and fade to white when it’s time to change them (usually every three months). Although this isn’t necessary, it’s a good way to keep track.
