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. Normally, vertical apical fractures will cause you more pain than any other type of fracture. Most often, people will concentrate on the thought of getting the shot, which will only magnify the pain. Something that normally doesn t hurt, can get a lot worse simply by thinking in your mind that it will be painful. In most cases, the numbing shots will work very well with one or two applications. Even though you may be able to use certain products to stop the pain, the pain will always come back until you get the problem fixed. 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. This acid is very harmful to teeth, as it can eat through the dentin and enamel in no time at all. If you don t do something about it, the acid will continue to eat at the tooth until there is nothing left to say - leaving you no choice but to get the tooth extracted. Over time, the tooth enamel will start to break down beneath the surface of your tooth, even though the surface will appear to be fine. 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. Decay is the main reason for pulp in the tooth dying. Once the decay has reached the pulp, it will keep eating away until the pulp has died. Once it dies, the toxins from the decay will be released into the root tip and make it s way into the jawbone. Cracks can make your tooth feel as if it is exploding, as they expose the dentin and nerves to the air and anything else you put in your mouth. If you don t get them fixed, they will get worse, possibly leading to your tooth breaking off at the gums. Pulp irritation is another cause of toothaches, as it occurs after dental treatment.
