Questions:I seem to recall that my first electric toothbrush came with directions not to use toothpaste. My current one has no such restrictions, but do I need it?
Answer:You can brush without a toothpaste (only with water), but it won’t be as effective as with one.
The most important aspect of using a toothpaste is the its ability to increase fluoride levels in the oral cavity. Fluoride will strengthen the teeth against acids produced by bacteria as a byproduct of their metabolism.
Just make sure to choose a low abrasive toothpaste; plain with no granules inside is you’re best choice.
There are a couple of different types of electric toothbrushes. One type uses vibration, the other uses rotation-oscillation. It is believed that the rotation-oscillation type is more effective at reducing plaque. In addition, some electric toothbrushes generate an ultrasonic wave to clean the teeth. There are also numerous styles of brush heads, designed for deep cleaning, for sensitive teeth and gums, for patients with orthodontic braces, and so on.
With all that extra power and polishing, the type of toothpaste you choose becomes extra important. If the toothpaste is too abrasive, it can erode tooth enamel. Most electronic toothbrush manufacturers recommend a gel-type toothpaste for use with their equipment.
