Why do teeth hurt?

Is toothache always a bad thing? At first glance, the answer is unequivocal, because no one wants to experience unpleasant and sometimes painful sensations from aching or shooting toothache. However, there is a positive point in the fact that the pain still appeared - this is how a person finds out that he has health problems. Some diseases of the teeth can be asymptomatic and lead to serious complications, and the appearance of painful sensations is a signal to take action.

Causes of Toothache

Caries

The most common cause of toothache is caries. It is medium and deep. The first is distinguished by the fact that sometimes it proceeds covertly, without delivering any particular inconvenience to a person for the time being. Food particles get stuck in carious cavities, sometimes the affected tooth reacts to mechanical or temperature effects. If you do not eliminate caries at this stage, then it will go from middle to deep. Another danger - with a fast-flowing form, a large number of teeth can be affected.

If the moment of treatment is missed and the patient turned to the doctor too late, then he will have to deal with deep caries.It is manifested by pain after food gets into the carious cavity, and pain is also present when brushing teeth, while taking hot or cold. If untreated, and at this stage, the disease will affect the nerve, which threatens to develop pulpitis.

Pulpitis

Microorganisms and their toxins in the carious cavity reach the pulp and cause an inflammatory process. This leads to increased blood flow to the affected area, which increases pressure on the nerve fibers. At the initial stage, the pain is weak and short-term, but it can develop into acute pulpitis. This happens if the cause of the irritation of the pulp is not eliminated and irreversible changes have occurred in it, caused by the action of bacteria from the carious cavity. You can find out acute pulpitis by the following features:

  • acute or dull pain;
  • pulsating or constant;
  • the duration varies from several hours to several days;
  • especially a tooth hurts at night.

A particular risk with this disease is that acute pulpitis can become purulent, at which the pain becomes almost unbearable and threatens with temporary disability.The lack of timely treatment will lead to a complication - the appearance of chronic pulpitis. It can occur periodically, as a reaction to the appearance of irritants. For example, when biting food, when inhaling cold air, while eating hot or cold food. It may also manifest a sudden pulsating pain of strong intensity. If the treatment is delayed, then chronic pulpitis will turn into a new disease - periodontitis.

Periodontitis

Periodontitis suggests that the problem has deepened, and the inflammatory process has penetrated the soft and hard tissues of the jaw. There is an acute and chronic periodontitis. In the first case, the toothache is constant, extends to the face area. In humans, there is a general weakness, fever, headache, swelling may occur. Sometimes purulent discharge may occur from the root canal. In chronic periodontitis, the nerve dies off, and the disease is almost asymptomatic. The consequences of this condition can be complications such as granuloma, root cyst, periapical abscess, phlegmon.
