Once your tooth has become abscessed, your dentist won t immediately pull it. If a tooth that has abscessed is extracted once the infection is still present, it can quickly spread. Your dentist will instead prescribe you some antibiotics that can help to destroy the bacteria. The dentist can also perform a root canal, in an attempt to remove dead or decayed tissue. Even though the pain may go away, the problem will still be there until you go to the dentist and get it treated. Although the dentist is the preferred way to go, you may have to wait on an appointment, or the toothache may occur on a weekend or a time when the dentist isn t available. Your best advice is to seek dental care ASAP, as the infection can always return at any given time. 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. Many people take this the wrong way, and immediately stop flossing, usually for good. Bleeding is very common, and should be expected with flossing. When you brush your teeth, you miss a lot of food particles and debris that continues to build up in your mouth. No toothbrush is designed to get every area of your mouth, as all of them miss hard to reach places. When you brush your teeth, you should avoid using pressure but instead use short, gentle strokes. You should focus on hard to reach places, and make sure that you get the areas between your teeth as well. You should also make sure you get eating surfaces as well, along with your upper and lower gums. The first type of crack is known as an oblique supragingival fracture. This fracture is found above the gums, and normally happens when you bite down too hard on something. Normally, this fracture doesn t involve the nerve. Once the fractured area of the tooth breaks off, the pain will go away. Although the exposed dentin may cause you some pain, you can visit the dentist and have it repaired.
