The cyst that forms under the tooth, or rather under the tip of its root, is a small, round cavity that has a membrane that retains fluid in it. The size of such a cyst can be from a few millimeters to a couple of centimeters. Cysts must be treated, in the opposite case complications are inevitable.
Cyst of the root of the tooth - causes
The cyst arises as a reaction of the body to an infection that has come from outside. Most often this happens due to the development of periodontitis. Periodontitis is an inflammation of the periodontal tissue, a complex of tissues holding the tooth in the hole and providing it with nutrition and sensitivity.
Another reason may be poor-quality pulpitis treatment in the tooth, when the filling material is not brought to the top of the tooth root or a fragment of the tool remains in the channel. Cases of perforation of the root canal wall with a mechanical instrument are common. The most common cause of cysts on the root of the tooth is a severe acute or chronic injury.
Cyst of tooth - symptoms
While the cyst has only been formed and its size does not exceed a couple of millimeters, it often does not make itself felt. Such small cysts, which have not yet grown beyond 0.5 mm, are called granulomas by doctors. Most often, they are determined only by the X-ray image, which shows a small rounded spot with clear outlines. But, eventually, the root of the tooth cyst begins to increase in size and cause the following symptoms:
- Pain that occurs in the tooth when biting. It seems that the tooth is pushed out of the dentition, a strong sense of bursting and heaviness, which is growing. In addition to the tooth, the gum in his area also hurts.
- Swelling of the mucous gum around the tooth. The gums become red, friable, edematous, painful on palpation. Later the swelling passes to the mucous membranes of the cheeks and lips. With suppuration of the cyst on the gums, a fistula is formed - a small hole through which pus is released. Fistula is often formed with the tooth cyst under the crown. Usually the formation of a fistula brings with it a relaxation of pain.
- Enlargement of lymph nodes. The tooth has a good lymphatic drainage in the adjacent lymph nodes , so that the infection spreads throughout the body. This is often the case with a follicular cyst, that is, a tooth tumor that is formed from the rudiment of an uncut or supercomplete tooth. More often such cysts are found in children.
- Increased body temperature.
