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. Pulp irritation is another cause of toothaches, as it occurs after dental treatment. No matter how well your filling or crown was done, the materials that were used to fix the tooth can end up causing pain later on down the road. There really is nothing you can do, as crowns can sometimes come off or the filling can sometimes come out. Minor fractures aren t that bad, as they can normally be smoothed out using sandpaper. Sometimes, the tooth can also be restored with a composite. Either way, you ll need to make sure that you use extreme caution with the tooth for the next few days. The more moderate fractures, normally include damage to the dentin, pulp, and even the enamel. When you visit a dentist, you shouldn t hesitate to ask him any questions that come to mind, so you can be more relaxed. You should always keep in mind that you are customer, and the dentist is the one who needs to make you feel relaxed. Never should you feel intimidated, as the best dentists will do everything they can to establish a sense of trust. Although you may suffer from sensitive teeth, you can rest assured that they can be treated. Normally, this condition presents tooth pain after drinking cold liquid, eating hot or cold foods, or breathing cold air. If the pain becomes too much to bear, you should immediately see your dentist, as the nerve of your tooth could be exposed. 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.
