Tooth pain is actually possible to eat sugar, many parents in life will say to their children to eat less sugar, otherwise they will have toothache, this statement cannot be said to be wrong, but it is inaccurate. Because eating candy is not the direct cause of toothache, most of the direct cause of toothache is tooth decay caused by bacterial infection to the tooth body, and further development of pulpitis, so there are many links between eating candy and toothache. Simply speaking, eating sugar and toothache are not directly related, eating sugar does not aggravate the symptoms of toothache, nor does it alleviate toothache, but if people who often eat sugar do not clean their mouths particularly well, it is relatively easy for the bacteria in the mouth to breed, and caries will easily develop, increasing the risk of pulpitis, but this does not mean that eating sugar will definitely lead to toothache.
