In ancient times, many princes and nobles were deeply troubled by toothache. As early as the Eastern Han Dynasty, the imperial doctor Zhang Zhongjing had the consciousness of killing the nerve on decayed teeth. The medical book he left behind recorded a formula containing realgar, which can help people kill the nerves of teeth. But in terms of composition, the herbs in this prescription are toxic when mixed together, so this prescription has no practical significance. Since then, people have been facing the problem of toothache, and there is no solution. If you have a toothache, most people can only hold on. Others use drunkenness to paralyze themselves and relieve the pain when they have toothache.
In ancient times, there was also the technology of gear shaping, but unlike modern times, gear shaping had no practical function at that time, just because it was beautiful or a status symbol. In ancient times, dignitaries or rich people often used precious metals or precious wood to inlay their teeth. Teeth made of this material cannot be used to chew food.
In ancient times, there were records of tooth extraction and filling, but in history, many people died of tooth inflammation after tooth extraction and could not be cured. The methods of filling teeth have certain scientific basis and practical significance. However, due to the lack of effective nerve therapy in ancient China, filling teeth can only fill the gaps between teeth, but can't solve toothache. To sum up, the awareness of treating teeth in China is very advanced, but there is a lack of correct treatment methods. Therefore, the problem of toothache has puzzled the ancient people in China for thousands of years and has not been solved. It was not until modern times that stomatology of western medicine was introduced into China that correct solutions were found for various dental problems. Finally, I don't have to endure toothache.
