Electric toothbrushes can clean teeth more effectively than manual toothbrushes, will lower your risk for toothbrush abrasion, and can help prevent tooth staining. If you have the money you should definitely invest in one. However, before buying, make sure to read a few good electric toothbrush reviews so that you can choose right and get the best fit for your needs.
There is a bit of a learning curve to using an electric toothbrush guide correctly. Since the brushing motion is done entirely by the toothbrush, the only thing you need do is position the toothbrush head in a way so the bristles reach the right areas. Give it a little time and you will get the hang of it very soon.
As you can understand, your manual toothbrush has a head differently shaped than an electric one. So I suggest you spend some time getting familiar with the electric toothbrush before you turn it on for the first time. Also the vibrations of the toothbrush can be distracting and a bit disorienting for some people in the beginning, so it is helpful to first practice positioning the toothbrush go through the motions we will talk about before turning on the toothbrush. As electric toothbrush reviews will tell you, you have to learn to crawl before you can walk.
Correct brushing technique requires that you get a feeling of the places where the toothbrush bristles are touching you. Our teeth differ from each other and hence one broad brushing method would not work for everybody. You must be able to feel the bristles slightly in-between your teeth and also along your gumline so you can individualize your brushing and know you are cleaning the right spots. I suggest that in the beginning you use your electric toothbrush without toothpaste. Without the distraction of the sudsy toothpaste you can really focus on where the toothbrush bristles are touching.
Dental plaque forms first in-between teeth and along the gumline, so you should put your attention on these places by moving the bristles of your toothbrush in the direction of your gums slantingly just like you normally do. You should be able to feel the bristles along your gumline.
I use my electric toothbrush in the same general pattern to clean my teeth as I do my manual one, the only difference is the cleaning each area gets. In this case all the work is being done by the toothbrush, so you simply have to place your toothbrush along your gums and a little in-between your teeth.
