Dental Cyst: Causes, Symptoms, Consequences


Some believe that a dental cyst is in fact not a dangerous disease, that it can remain for years, and if necessary, you can deal with it even at home. Others panic on just hearing these two words. Let’s figure out what such a cyst is and how to treat it.

What Is a Dental Cyst?

A dental cyst is an inflammatory mass in the form of granule, which appears as a protective response of the body to injury or infection. Externally, the tumor is a bubble with a diameter of several centimeters filled with fluid or pus. The fact is that when the body itself tries to fight the inflammation, the affected cells begin to die, and for isolating them from the healthy tissue, a shell is formed around. To see this cavity at the early stages is possible through DPR.

Why Does a Dental Cyst Appear?

The main causes of cysts in teeth are:

  • dental cyst causesInfection in a root;
  • Trauma;
  • Chronic diseases of nasopharynx and oral cavity;
  • Inflammation of periodontal tissues (periodontitis);
  • Reduced immunity;
  • Caries;
  • Poorly installed filling;
  • Difficult eruption of wisdom teeth.

The Symptoms of Dental Cyst

A difficulty of diagnosing the cyst consists in the absence of symptoms. In some cases people can pay attention to such signs of a dental cyst as the enamel darkening or unpleasant sensations when chewing food, but most people attach no importance to that. By the time it starts to hurt, a granule can already grow up to 1 cm in diameter. The patient begins to feel other signs. Here are the symptoms of the cyst at this stage:

  1. follicular dental cystAching pain in the area of inflammation;
  2. Swelling gum;
  3. Enlargement of lymph nodes;
  4. Fever;
  5. Headaches;
  6. General malaise.

You must not ignore these symptoms, otherwise there will be severe consequences, and the removal of a tooth with a cyst is not the worst of them. At the first sign of the disease, you must consult a specialist. A dental cyst is often confused with granuloma. It is other dangerous disease, in which there appears a rounded tumor. It is important to distinguish them because the diagnosis directly affects the treatment plan and its forecasts. In cases of granuloma the therapeutic treatment is usually sufficient. A cyst requires more radical measures.

How to Deal with a Tooth Cyst?

As it is difficult to find a cyst under a tooth (whether it be a follicular dental cyst or a residual dental cyst), since it is formed slowly and without pronounced symptoms, the patients usually visit a doctor in the later stages of the disease – when there is already pain, malaise, and other signs of inflammation. Formerly, in such a situation the affected tooth had to be removed. Today there are different methods of cyst treatment without the loss of a dental unit. Depending on the severity of the disease, a cyst can be removed either by means of therapeutic method or with the help of surgery.

Therapeutic treatment includes scrubbing cysts from the channels, their processing and filling. Surgical method involves a removal of the damaged part of the tooth root with preservation of the tooth – a doctor removes a cyst, and the missing tissue is filled with special material. Indications for tooth removal due to a cyst take place in special cases, including a cyst of wisdom tooth. Is it essential to treat a dental cyst? The answer is yes. Still, if it concerns a child, and it appeared before the change of teeth, this cyst will burst on its own, due to the friction of the gums with each other.

How Dangerous Is a Tooth Cyst?

The irony is that, being formed as a defense reaction of the body, a cyst under a tooth can eventually lead to serious complications. The main of them are:

  • residual dental cystPeriodontitis: an advanced case of a dental cyst, in which the inflammation in the tissues spreads to the bone.
  • Dental abscess: purulent inflammation in the jaw area. Such a complication is accompanied by a tumor of soft tissues, including the cheeks, and severe pain.
  • Tooth loss: it occurs when the cyst is not treated. In this case, the lesion extends to the adjacent teeth (although the cyst itself is not the reason for a removal).

In addition to the above, the worsening of the disease can lead to even more serious consequences: purulent abscess, osteomyelitis, sepsis, and even a fracture of jaw. Therefore, if you have a cyst, treatment should follow immediately. It is important to remember that the sooner a dental cyst is identified, the higher are the chances of its successful treatment. So instead of having to deal with the consequences of such a cyst, visit your dentist regularly to maintain the health of your oral cavity.

    Why are teeth removed with large inflamed epithelial cysts that are not loose and full roots…just some bone loss? Or can they be left in? How about teeth with 100% resorbed teeth? Or a tooth with one root left?
