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. 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. If the decay has managed to get to the nerve, you may end up needing a root canal to get rid of the dead pulp. When the dentist decides he can fill your tooth, he will remove the cavity then fill the hole with a material listed above. 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. 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. The exposed root tips contain small tubules that lead directly to the nerves of the teeth. Whenever pressure, hot, or cold elements travel down the tubules, it will trigger the nerves and result in pain. For many years, there has been a lot of controversy as to the need to remove these teeth. If the teeth don t cause any harm or pain, they are normally fine to stay in place. If they present a bad position or cause you a lot of pain or discomfort, they will need to be removed. When the wisdom teeth first come in, they will sometimes be impacted. All About Cavities Cavities can best be described as tooth decay. As we all know, tooth decay is influenced by what we eat, how we take care of our teeth, and the amount of fluoride in our toothpastes. If your family has a history of tooth disease or teeth problems, then you may inherit it that way. This is very common, as many people inherit tooth problems that have been passed down from generation to generation.
