It normally doesn t affect the nerves, although as a result of the tooth area being lost, you may need to have a root canal to clean out the tooth before having a crown put on it. The seriousness of this fracture depends on how far it has went beyond the gum line. If it has made it s way deep into the gum line, you may not be able to save the tooth. The material that makes up the composite filling is mixed then placed directly in the cavity, where it hardens. They last several years, although composite isn t recommended for large cavities, or areas where they may chip. The final type of filling is porcelain. Porcelain is very common, and produced in lab where it will be matched to your teeth then bonded to the affected tooth. Foods that are rich in sugar or starch are eaten by bacteria found in plaque, which will produce acids that eat through teeth. This acid is very harmful to teeth, as it can eat through the dentin and enamel in no time at all. If you don t do something about it, the acid will continue to eat at the tooth until there is nothing left to say - leaving you no choice but to get the tooth extracted. Providing the pulp hasn t been damaged, your dentist will be able to restore the full shape and function to the fractured tooth. In cases where pulp damage has occurred, the dentist may need to do a root canal or other type of serious surgery to repair the tooth. Whenever you encounter a dental emergency, you shouldn t hesitate to contact a dentist immediately. Your best advice is to seek dental care ASAP, as the infection can always return at any given time. If you don t get problems fixed as soon as you can, they can spread and cause you more problems with your teeth. Cavities will need to be filled, while the rotten or dying teeth will need to be extracted. A Look At Flossing Along with brushing your teeth, you should also be flossing on a daily basis. Flossing will remove plaque and debris in areas that your toothbrush isn t able to reach. A buildup of plaque can lead to gum disease or tooth decay, which is why flossing is very important. If you floss immediately after brushing, you ll notice that your gums and teeth will be much healthier.
