Nowadays, many people have a “dental phobia” when it comes to dental care, and they feel afraid and scared. Especially children, sometimes when they hear the sound of grinding teeth, they will immediately cry and refuse to be treated, and many adults, although they know that their teeth should be treated or pulled, because they are afraid of pain, so they have been dragging, the more they delay the more powerful, some dental diseases that only need simple treatment will become very complicated, and some people because of the fear of pain caused a bunch of rotten teeth in the mouth seriously affect the aesthetics and function. So why is there such a status quo? It is related to the early days of dentistry. At that time, the grinding machine was pedal, a few dozen revolutions per minute, no anesthetic or anesthesia effect unlike now, hard on the teeth grinding, and torture is no different, especially when grinding to the nerve closer to the tooth, the heart of the pain ah! And in the past, the extraction of complex teeth had to be assisted by a hammer in order to pull them down. But now it is different, first of all, there are advanced anesthesia technology and anesthesia drugs, which can achieve a good analgesic effect throughout the whole process, and the imported painless anesthesia instrument can achieve no pain when playing anesthesia, so that the real “whole process of painless treatment”. Moreover, the dental drill used nowadays can cut teeth at a speed of more than 300,000 revolutions per minute, which can complete the treatment more efficiently. There are also filling techniques that do not require a drill, such as laser fillings, which have been applied clinically and are painless without anesthesia. For tooth extraction, the use of high-speed dental drills can now eliminate the pain of hammering. So, how far is painless dentistry from us now? In fact, it is perfectly possible to achieve “painless” dental treatment with the current medical methods. Of course, we cannot exclude the individual differences of doctors and the unbalanced development of medical technology, so this painless technology cannot be realized in all dentists and dental clinics in this era, but you can choose a good dentist, a good doctor, and have your own dentist like the foreigners, and have healthy and beautiful teeth!
