Cracks can make your tooth feel as if it is exploding, as they expose the dentin and nerves to the air and anything else you put in your mouth. If you don t get them fixed, they will get worse, possibly leading to your tooth breaking off at the gums. Pulp irritation is another cause of toothaches, as it occurs after dental treatment. Silver fillings on the other hand, are less expensive than gold materials and they can be quite resistant to wear. With their color being dark, they are easier to notice than composite or porcelain fillings, and aren t recommended for visible areas of the mouth, especially the front teeth. Composite fillings are a common type of material, as they match the color of your teeth. Normally, IV sedation is preferred during wisdom teeth removal, as most people don t want to hear the grinding and snapping of the teeth. It works through your veins, as the anaesthesia is inserted into your arm through a vein. If you have chosen either laughing gas or an IV sedation, your dentist will administer either of the two before he gives you shots or goes any further. In most cases, if the problem goes without being checked, it can lead to serious trouble and maybe even become a life threatening situation. Normally, when you have a toothache, you ll experience tremendous pain. The pain will stem from the affected tooth or the jaw, and you ll know it almost immediately. Once the fractured piece of tooth breaks off, it normally remains attached to the gums and cause result in terrible pain until you get it removed. Once you have had the piece of tooth removed from the gums, the tooth will be similar to the supragingival fracture. 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. Although this is sick to say the least, this remedy was discarded in 1728, proven to be non effective and replaced by other more suitable treatment. As time passed, doctors proved that the best way to stop the pain was to clean and remove the nerve and pulp of the tooth. Root canals are a very common procedure these days, as they help to save the tooth by removing the dead or dying pulp.
