Hello! You can brush out white teeth at ordinary times. If you have the idea of cleaning your teeth, you'd better not go. I suggest you use two when brushing your teeth.

A toothbrush, a soft hair and a medium hair brush the residue on the root with a soft hair toothbrush, causing yellowing.

Mainly it. Brush the middle part with a medium-sized toothbrush, which can protect both sides. Brush your teeth twice a day and get into the habit of picking out your pockets after meals. Stick to it for a while, and you will find that your teeth must be much whiter. ///Note: The toothbrush has no effect after being used for one month, and the quality is better. I can say that your toothbrush has been used for too long. It doesn't make much sense. You'll thank me after trying. I am deeply touched by this.

Mind you, tooth washing has an effect on teeth, and the gap between teeth will become larger.
