What are the advantages and disadvantages of electric toothbrush brushing compared with manual brushing?

If you have to force a defect, electricity, the purchase cost is high.But in addition to these two, both the level of cleaning and oral protection, is better with an electric toothbrush.

Electric toothbrush saves trouble, evenly, does not have to exert too much force, and also protects teeth.You often poke your gums when you use your hand.And manual is not good to master the strength, the damage to the toothbrush is also great.I feel good with my own electric toothbrush, and I feel like 2 minutes is not enough.2 minutes of brushing time will automatically come point power off, ensure enough brushing time.Brush your teeth before the basic brush more than a minute, brush casually, now feel 2 minutes are not enough. Electric toothbrush makes full use of toothpaste. After brushing, it will feel that all parts have been brushed, and the teeth will have a sense of uniform granularity.It was a feeling I hadn't felt before.It is very economical to use toothpaste.
