Once the tree matures, it can reach heights of up to 60 feet, with the bark being light grey in color, and the leaves and the fruit resembling the black walnut tree. The bark of the tree can be applied to the gums, helping to alleviate toothache pain. Yarrow on the other hand, can be found in Asia, Europe, and North America. If the pain becomes too much to bear, you should immediately see your dentist, as the nerve of your tooth could be exposed. Normally, sensitive teeth starts when the gums begin to pull away from the teeth. With the gums being a protective blanket, they cover and protect the teeth s roots. When the gums recede and pull away, the roots have no protection, and therefore they will be exposed. Sometimes, you can save the tooth with a root canal, even though it is normally lost later on due to an abscess of the bone that surrounds the fracture. The last type of fracture is the most difficult to deal with. Vertical apical root fractures occur with the tip of the root, and can cause you severe to intense pain, even if you ve had the nerve removed with a root canal. 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. The gold fillings that are used are made in a laboratory, then cemented into place by the dentist. Gold material fits well with the gums, and can last you for many years. The fear of pain in dentistry is so high in fact, that many people fail to go to the dentist until their condition becomes so severe that they have no other choice than to see a dentist. A majority of individuals are terrified of the dental chair, although once they are numb, they sometimes fall asleep. 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.
