I believe that many people have experienced the torture of toothache, which seriously affects life and work, and many people hold the idea of “bear it and it will pass”, thinking that toothache is nothing, which is actually very wrong. If you have a dental disease but always delay, it may become the cause of chronic nephritis, viral myocarditis and other serious diseases, and then it will be too late to regret. In addition, some systemic diseases such as diabetes and AIDS can also be evident in the oral cavity. Toothache is actually a disease state that must be taken seriously and prevented before it happens. So what is a toothache all about? First, let’s get to know the structure of the tooth. To use the simplest analogy, it is a pressure cooker stewing pig’s feet, the pressure inside is increasing, but it cannot break through such hard tissue as tooth enamel, so it produces severe pain.
