Danger of Cysts

The cyst begins to develop with a banal swelling of the gums. People are often shocked when they hear a doctor’s conclusion about the dental cyst. Dentists usually stay quiet about what it is and its causes. This is a formation of benign nature, which has a capsule that prevents spreading of infection to the surrounding tissue.

The cyst may increase in size and destroy adjacent teeth. With rupture a cyst above tooth root can lead to blood infection. In such cases, it is possible to remove the cyst only together with the tooth. In the initial stages, the disease is asymptomatic. This is why it is insidious and dangerous.

Weakening of the immune system, infectious diseases and hypothermia can provoke an increase of the cyst in the size. cyst on tooth canalCysts often cause complications and consequences:

  • They destroy bone tissue, which leads to the loss of teeth and jaw deformation, sometimes to their fracture;
  • Formation of phlegmosn, abscesses, osteomyelitis;
  • Development of chronic sinusitis (when located in the sinuses);
  • Degeneration into a malignant formation;
  • Sepsis.


Late stage of cyst are treated surgically. Initially, the purulent capsule does not manifest itself. A tooth with a cyst is found only in the picture of other nearby teeth. After some time, there is a weak pain when pressing on the gums or when biting. Timely therapy allows to cure the tooth without removal. The late stage of the disease has the following signs:

  1. Aching pain in the gums, it becomes hard to eliminate the pain;
  2. Sometimes there may be high temperature;
  3. Swelling, redness (hyperemia) of the gums, a cheek swells;
  4. Pain in the head (when located near the sinuses of the nose).

The final stage is accompanied by the formation of fistulas (passage from the cavity with pus and gum, which removes pus, after deformation of the pouch). Each stage is easy to diagnose by making an x-ray of the tooth.

Treatment or Removal

After mechanical opening, the cavity is treated with a laser that removes the contents and disinfects the wound.

Treatment with Surgery

The removal of the cyst by resection of the upper layer of the root. This technique preserves the tooth, allows not to carry out the filling of the channels and not to replace the crowns. If a pin is installed in the tooth, it is opened, breaking only the top of the chewing part.
