What is the reason for gum bleeding when using electric toothbrush?

There are many reasons for gingival bleeding of electric toothbrush. Here are some possible reasons:

1. Incorrect brushing posture or excessive force. When many men brush their teeth, they think that they need to press hard to clean their teeth. This is not right, especially the electric toothbrush, when it vibrates too hard at high speed, it will not massage the gums, but will hurt them.

2. Too much tartar. Some people have too much dental calculus, which will stimulate the gums, causing inflammation, swelling and congestion of the gums, ranging from bleeding when brushing teeth, sucking, biting hard objects or picking teeth to bleeding when there is little or no stimulation.

3. Patients with gingivitis and periodontitis. This posture, which is mainly used for brushing teeth, is incorrect.

I use a very cheap electric toothbrush. Here are some famous brand electric toothbrushes, which are not as expensive as ordinary manual toothbrushes. In order to reduce the cost, the bristles are particularly hard and the vibration frequency is chaotic. That's not brushing your teeth, it's grinding your teeth.
