The present invention is related to the appliance for cleaning teeth, in particular to a toothbrush monitoring device.

Brushing your teeth is a good thing, just like exercising is good for your health, but incorrect exercise posture can actually cause harm to your body. Brushing your teeth is not about brushing your mouth with a toothbrush. The point is to get rid of plaque. Plaque is a biofilm (biofilms) that gradually deposits on the surface of the teeth, and the acid produced by the bacterial metabolism in the plaque will erode the enamel on the surface of the tooth, and the most effective way to remove plaque is to brush your teeth. Use the friction of the bristles to scrape off dental plaque. However, the force of brushing should not be too strong, so as not to damage the enamel, which will cause the nerves of the small tubes of the dentin to be exposed, which will cause tooth sensitivity. If the gums are constantly damaged and inflamed, finally Root canal treatment may be required.

Therefore, the strength of brushing teeth must be well controlled, to clean the teeth, but not to hurt the teeth.
