Porcelain fillings match the color of your teeth, and are resistant to any type of staining. The costs for porcelain fillings can be very expensive, some costing as much as gold fillings. If a cavity, decay, or even a crack has managed to damage a large area of the tooth, you may need a crown or a cap. Many years ago, ancient civilizations used this method to save teeth that would have been lost otherwise. These civilizations offered root canals to those such as queens, kings, pharaohs, and the rich. The teeth from peasants were normally extracted then sold to aristocrats. Many years ago, doctors believed that worms were the reason for tooth decay. Once more of the bone has been dissolved, there will be nothing left to support the tooth, meaning that it will become loose and end up needing to be extracted. The symptoms of an abscessed tooth are easy to see, as they include severe pain in the affected area, red or swollen gums, a bad taste in your mouth, swelling around the area or the jaw, and possibly a high fever. Another way to stop the pain is to use Tylenol or aspirin. If you are going this route, you should use tablets that dissolve. Simply take the tablet and put it in your mouth, then use your tongue to hold it against your tooth. The aspirin or Tylenol will start to dissolve, and work it s way into your nerve and stop the pain. 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. Normally, this condition presents tooth pain after drinking cold liquid, eating hot or cold foods, or breathing cold air. 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.
