If not taken care of properly, the jawbone can become infected, which can lead to death in rare cases. To fix this problem, the dentist will need to perform a root canal. During the procedure, he will numb the area then drill a hole into the tooth. Using various tools and equipment, he will go down inside of the tooth and scrape away the nerves and dead pulp. When the wisdom teeth first come in, they will sometimes be impacted. Impacted teeth will normally need to be extracted. Sometimes they can be pulled, although in most cases they need to be cut out by a qualified surgeon. When the time comes to have your wisdom teeth extracted, you ll need to go to an oral surgeon and have a consultation first. Adults who suffer from a dry mouth are more at risk for cavities, as they have a lack of saliva in their mouth. Dry mouth is very common, and is normally the result of medications, illness, and radiation treatment. Tobacco users will also suffer from dry mouth, as the tobacco will use up the saliva in the mouth and leave the user with nothing to keep his or her mouth moist. Those who suffer from dental anxiety will try to avoid going to the dentist, which results in problems. When someone who suffers from dental anxiety finally goes to the dentist, they normally find that even the smallest of problems can turn serious and require a lot of work and intervention from the dentist. The materials used for fillings include porcelain, gold, composite resin, and amalgam. There is really no best type of filling, as several factors come into play. Your reaction to different material, the shape of the tooth, extent of repair, and where the filling is needed will be determining factors as to what material is used with your filling. Either way, you ll need to make sure that you use extreme caution with the tooth for the next few days. The more moderate fractures, normally include damage to the dentin, pulp, and even the enamel. These fractures can be nothing to worry about at times, yet painful with other cases. Providing the pulp hasn t been damaged, your dentist will be able to restore the full shape and function to the fractured tooth.
