You don’t have to kill the nerve to get an all-ceramic crown tooth. All-ceramic crowns refer to full-crown restorations that are made entirely of porcelain material and are aesthetically pleasing. Whether or not you need to kill the nerve to get an all-ceramic tooth depends on the health of the tooth. If the tooth has lesions exposed nerve, need to kill the nerve, and then do all-ceramic dental restoration; if the tooth is in a healthy state or only a slight injury without exposing the nerve, generally do not need to kill the nerve. Kill the nerve, also known as root canal treatment, refers to the lesions or inflammation of the nerve through the drug to make its necrosis, and then extracted, so as to relieve the symptoms of tooth pain. All-porcelain teeth are a common way of restoring teeth with a high degree of simulation and aesthetics, but improper care can lead to dislodging or chipping. After doing all-porcelain teeth should pay attention to keep your mouth clean, develop the habit of brushing your teeth after meals, and go to the hospital regularly for checkups and cleanings.
