When the time comes to have your wisdom teeth extracted, you ll need to go to an oral surgeon and have a consultation first. During the consultation, you ll take a few x-rays that will let the surgeon know how bad your wisdom teeth are. He will go over the results with you, take a look in your mouth, then tell you what options you have. Root canals are a very common procedure these days, as they help to save the tooth by removing the dead or dying pulp. The pulp exists inside of the tooth, and can spread to abscess if it isn t taken care of. The tissue in the pulp is kept alive by the blood vessels that come from the tip of the root and travel along the root canal into the tooth. 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. Normally, sensitive teeth starts when the gums begin to pull away from the teeth. 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. Once the acid has managed to eat away enough of the enamel below the surface, the surface will collapse, which results in a cavity. After this has happened, if you don t get it treated, the tooth will continue to be eaten and the cavity will continue to spread until all of the tooth has been eaten, after which the enamel will be gone and your root will be exposed - which can be very painful. Even though there are many causes to toothaches, there are things you can do to stop and pain and prevent toothaches. You should always brush your teeth on a daily basis, and go to the dentist for your regular checkups. If you get a toothache you should always go to the dentist and get the tooth fixed.
