If the cavity exists in the tooth, you will be able to see it, as it will change the color of the affected area. If you notice a color change or a blackened area in your tooth, you should make an appointment with your dentist immediately. What you eat is a big contributor to cavities. If you eat a lot of sweets or drink a lot of soda, you will be at a higher risk for cavities. If the root tips have managed to wrap themselves around the bone, the removal process can be very time consuming and quite painful. 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. There really is nothing you can do, as crowns can sometimes come off or the filling can sometimes come out. If this happens, all you can really do is go back to the dentist to get the problem fixed. If you have an exposed root or nerve, it can also be the cause of your toothache. This normally happens due to rough brushing, receding the gums and exposing the root. If the bristles start to get worn down, they can tear away at your gums, leading to sensitivity. To get the most from your brushing, you should always use a bit of common sense and ask your dentist for his recommendations. Brushing your teeth will help keep them healthy, and prevent the buildup of plaque and tartar. The inflammation that occurs is very painful, often times being a deep pain that makes you feel as if you are dying. If you leave it alone, the dry socket will heal. It will normally take around a month or so, although the pain won t let up during the healing period. If you have a dry socket, you ll find that antibiotics and even the strongest of prescription drug won t cure it. Normally, vertical apical fractures will cause you more pain than any other type of fracture. The resulting pain comes from the fragments putting pressure on the bone, causing the fractured pieces to strain. Just about the only way to get relief from this type of fracture is to get a root canal, as it will ease the pain and get the dead pulp out of the tooth that s affected with the fracture.
