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. Once the extractions have been completed, there is normally little to no swelling involved. Your dentist will prescribe you some pain medicine, which you should use as soon as you arrive home. If you are going to use IV sedation, you ll need to someone to accompany you, as you won t be able to drive home. You can use several techniques to overcome dental anxiety. Some of the techniques require mild sedatives, also referred to as sedation. Sedation is a way to relax, given by breathing or IV (Intra Vein) through a vein in your arm. Sedation will help you to calm down, although you will normally be awake to answer questions or talk to your dentist. If not taken care of properly, the jawbone can become infected, which can lead to death in rare cases. To fix this problem, the dentist will need to perform a root canal. During the procedure, he will numb the area then drill a hole into the tooth. Using various tools and equipment, he will go down inside of the tooth and scrape away the nerves and dead pulp. 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. Those who don t have sensitive teeth will have their gums covering the tubules, which prevents these types of things from happening. If you are already in pain when you visit the dentist, the shots will put your mind at ease and stop the pain almost immediately. If you have a tremendous fear of dental pain and simply cannot stand the thought of getting a shot, then you may be interested in laughing gas or IV sedation. Either of the two can help you relax before you the dentist applies numbing shots.
