My son has a toothache, panic when he calls, tooth decay, and keeps calling, ask for a leave today, and fill my son's teeth tomorrow during the day......

In addition, if you have any experience in this area, please also guide, not adults, but children, children of three or four years old,

I tried a lot of methods, taking anti-inflammatory drugs and biting ginger slices, but the child still cried in pain.

People say that it is not good to drill teeth at such a small age, and my son cries every day in pain if he doesn't drill teeth, and he worries me to death.
