"This tooth of yours is already decayed, if you want to completely resolve it, I suggest you have it pulled out." Lin Miao examined the location of the patient's toothache and found it had long been hollowed out, and most of the teeth in this mouth had problems.
It must be because of not brushing teeth regularly, neglecting dental health. There's no help for it, the poor at most use salt water for rinsing their mouths. Many people's teeth start to decay after turning forty, making eating meat a luxury.
Only wealthy families can afford tooth powder.
Lin Miao made his own toothbrush, but he could only let the people around him use it. If he wants to promote it, sorry, others might not accept it.
Even families of power and influence only use softwood or willow branches to brush their teeth. Haven't they thought about making a toothbrush?
