By using an electric toothbrush, it vastly simplifies the brushing motion as the electric motor of brush head ofthe toothbrush generates most of the force needed to properly clean the tooth and gums.

Let’s face it, toothbrushes aren’t something we have too much sentimental value attached to. In general, the average lifespan of a toothbrush is between 3-4 months. After that, the bristles start to fall off or become frayed and the whole toothbrush or brush head might become icky from a buildup of mildew and mold. This isn’t a problem you face when using an electric toothbrush. For electric toothbrushes3, they are made of different material so they are less likely to get stained. Also, they come with replaceable heads which tend to be made in a more environmentally friendly fashion.

Whereas a normal manual toothbrush, even the more expensive ones, is anywhere between $3 to $12 per brush.

2) Too many different brands

Anyone who’s purchased an electric toothbrush knows the feeling - when you’re looking for replacement brush heads at a local pharmacy and they just don’t carry any. The tough reality about electric toothbrushes is that new models are always coming out, under a variety of different brands. Remember to stock up beforehand to prevent spending an inordinate amount of time shopping for toiletries!

3) They require electricity

In many ways, this can prove to be a really irritating inconvenience.
