A dry socket is a condition where the blood clot that forms after an extraction detaches itself from the socket walls. Sometimes, the clot will dissolve, leaving the bone exposed to food, the weather, and even saliva. Once the bone is exposed, it can become inflamed. The inflammation that occurs is very painful, often times being a deep pain that makes you feel as if you are dying. When you brush your teeth, you ll notice that your gums have become very sore and they will start to bleed with little to no pressure. If you notice blood when brushing, chances are you have gingivitis. Anytime you brush your teeth or floss, there shouldn t be any sign of blood. During this stage of gingivitis, there is no loss of bone structure. The last type of fracture is the most difficult to deal with. Vertical apical root fractures occur with the tip of the root, and can cause you severe to intense pain, even if you ve had the nerve removed with a root canal. Even though the nerve may not be present, vertical apical root fractures cause a lot of pain, which occurs in the tooth. An IV sedation is the preferred way to have wisdom teeth extracted, as you ll be so relaxed you won t know what is going on. If you decide to just use local anaesthesia, which is numbing, you ll be fully aware of the procedure. You ll also hear the popping and cracking involved, which can make you feel quite uncomfortable. When performing a filling, the dentist will remove the decayed area of the tooth, clean around it, then fill in the area that he has removed with a special material that will cater to the shape and form of the tooth. Fillings work by closing out the area where the bacteria enters into teeth, helping to prevent any type of decay in the future. Chewing tobacco is a common contributor to toothaches and tooth pain, as the tobacco will eat away at your teeth until there is nothing left. It doesn t take long for it to happen either, especially if you have been chewing for a long time. Smoking can trigger toothaches as well, as the smoke is bad for your teeth and eats away at them as well.
