We brush our teeth everyday, but most people do the brushing carelessly. But when you have a problem with your teeth, and take a lot of time and money to fix it, and maybe you will regret why you didn't protect your teeth. When you decide to change myself and ask the doctor how to maintain your teeth, his answer must be: brushing your teeth properly! And he will also teach you how to brush,emphasize the Three-Three Principles (brush your teeth for three minutes every time, change your toothbrush every 3 months , clean teeth 3 times every day). Don't ask me how I know. I just filled my tooth twice and pulled out my teeth three times!
For dental cleaning, there is no doubt that toothbrush has the best effect.Especially some with high vibration frequency,the effect is more obvious.
