Deep caries: causes, symptoms, pictures and treatment

Deep caries – the disease, the causes of which may lie in the wrong diet, and the characteristic symptoms might depend on its effective treatment.

The procedure of treatment is a complex and expensive process, so pay special attention to prevention, using folk remedies.


Deep caries is a wide lose large areas of hard tooth tissues with subsequent spread to the dentin because of this disease is confused with the pulpit, but the latter only its complication.

The fact that the dentin that separates the pulp and a cavity, not for a long time can prevent the spread of harmful microorganisms and its destruction leads to the emergence of pulpitis.

Another feature of deep caries is a thin layer of dentin, a gradual destruction which is his last stage. This is the hardest phase of illness that requires proper treatment and quality dental care.

The disease causes considerable discomfort, and there is also the risk of injury of adjacent teeth and spreading infection throughout the oral cavity. In case of incorrect and delayed treatment of the patient can remain without teeth.


There are several types of deep caries, which are separated depending on the location and form of the disease:

  1. Chronic — short toothache in the affected area. Most often the pain arises after exposure to a tooth outside factors: hot or cold beverages, exposure to solid food in a cavity, the bottom of which was visually observed dentin. The cavity itself is well marked, wide edges. Occurs in the strong teeth, which was a resource for resistance to the disease, that pain is weak even when the disease is in its last stage of development.
  2. Acute — fracture processes occur very quickly, so the dentin is no time to recover, which leads to severe pain and rapid defeat of the nerve. A cavity covered with a large layer of dentin, and degradation products of dental tissues.

► According to the localization of deep caries may be at the point of contact of the crown with the gum, it is called cervical.

Mostly it occurs on the front teeth and is accompanied by problems in diagnosis, because it does not cause pain and aesthetic discomfort, but he is also dangerous form and affects the inside of the tooth at the same rate as other types of illness.

Why is there is a deep caries, and what is its etiology? The disease develops as a primary or on the tooth that has been treated. The process of emergence is characteristic of all carious diseases and is caused by the presence of pockets of acid that erode enamel and expose the tooth crown. The result is the protective complex of the tooth is broken and he begins to break down faster.

The fundamental reason is the incorrect care of the oral cavity (or lack thereof), irregular consultation with a dentist. That is why tooth decay often affects chewing teeth, including wisdom teeth.

The plaque is in most cases located on the side, in those places where the cleaning of teeth difficult. Front teeth at risk, but much less that is due to more careful care and visual appearance of the first signs of tooth decay.

The speed of development of carious process is influenced by the properties of the saliva of the patient, which can slow the growth in the number of harmful microorganisms.

What else may develop a disease? Separately identify the following several factors:

  • poor quality drinking water and malnutrition;
  • genetic predisposition;
  • mineral imbalance in the body;
  • professional activities;
  • pathology of growth and formation of teeth.

  • the defect of the tooth surface — the better the affected tooth visible when smiling or during a call, the faster the person goes to the dentist for help. If it is in a remote place, the patient goes to the clinic due to severe pain, which is typical for pulpitis;
  • bad breath — caused by the activity of harmful bacteria and the process of disintegration of the tissues of the affected tooth.
  • discomfort at sharp difference of temperatures — very cold or hot foods may cause brief episodes of pain that occur due to the lack of enamel on the affected area;
  • pain is not always a symptom, and even if the patient has complaints of pain, it is not strong and short-lived. Severe pain a person begins to feel when deep caries affects the nerve and enters the pulpit.

The stronger tooth and better its mineral composition, the longer it can resist tooth decay, although the process of destruction is already irreversible.


Detection of the disease is not difficult, but if deep caries must be distinguished from other similar diseases can be difficult. Common methods for differential diagnosis are probing and radiographs.

Deep caries is often confused with the different types of pulpitis:

  • fibrous form, in which there is mild pain even in direct contact of carious cavity with a foreign object, sometimes there is bleeding.
  • hypertrophic — diagnosis, you need to thoroughly explore the cavity. If it is pulpitis, then to see her bottom pink fabric, which can be enlarged pulp, and buried in the gum defect.
  • with acute pulpitis — the appearance of the affected area will be similar, but in sensing the patient feels very sharp pain.

In all other cases, recommend the use of diagnostic x-ray, which will help to distinguish the deep decay of the average or even from periodontitis. With an average caries the dentine layer will be dense and fairly large, and when deep in the affected area, it will almost be absent. In periodontitis the x-rays are detected changes in the tissues of the periodontium.

Treatment of deep caries

During treatment the main tasks of a dentist are: the removal of tissue affected by necrosis and the filling of carious cavity. It takes place in several key stages:

  1. To begin with, the physician must assess the condition of the tooth and the degree of its defeat necrotic processes.
  2. Is injectable anesthesia and dissection of the affected area.
  3. His antiseptic treatment and re-assessment. Then prepariruetsya unfinished areas.
  4. Pulp is isolated from the filling materials by means of a special gasket. If this is not done, it will be painful to respond to changes in temperature and exposure very filling.
  5. The installation of permanent seal.

Completely cure deep dental caries in adults and in one, albeit long, a visit to the dentist, but this is only possible if the walls of carious cavity are thick, and the pulp is not affected necrotic processes, otherwise you’ll need a temporary filling with the pharmaceutical composition and the treatment will last from 3 to 10 days.

A few popular recipes:

  1. Propolis tincture will prevent the spread of bacteria, use natural propolis, not a pharmaceutical solution. For this ball of propolis attach on the damaged tooth area of the tooth for 10-15 minutes. Important! Propolis is used only if the tooth is not yet developed in the pulpit.

In case of incorrect dental intervention can occur recurrent caries. A cavity is formed at the junction of the seal and healthy area of the tooth surface. Effects complications will be the removal of old fillings and a new course of treatment.
