A toothache will always come back, until you get the tooth taken care of. If you visit your dentist in time and he catches the problem early, he may be able to save your tooth. Normally, this will result in a filling, crown, or root canal, although you won t have to have the tooth removed. Dentists always look to save teeth, as they don t like to remove a tooth unless they absolutely have to. The sensitivity will begin going away, giving you almost immediate relief. When you brush, make sure you brush gently, and avoid using any type of force, as it will always cause your gums to recede again. In the event that using Sensodyne and fluoride mouthwash doesn t help, you should ask your dentist about other options available to you. Once more of the bone has been dissolved, there will be nothing left to support the tooth, meaning that it will become loose and end up needing to be extracted. The symptoms of an abscessed tooth are easy to see, as they include severe pain in the affected area, red or swollen gums, a bad taste in your mouth, swelling around the area or the jaw, and possibly a high fever. An abscess is very serious, as it infects the root tip. If left untreated, an abscess can result in death. Although you may not realize it, cavities are a very serious matter that can quickly spread to something even more serious. If you visit your dentist on a regular basis, he will check for cavities. Along with using the proper brushing techniques, you will also need to use the right toothpaste as well. There are a variety of toothpastes available, designed to help you with a variety of different conditions. You can get toothpaste that will prevent toothaches, stop sensitivity, and prevent things such as tartar and gingivitis. 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.
