The tooth responds to cold after fillings: tooth sensitivity

Sometimes a tooth responds to cold after fillings doctor. Unfortunately, the trip to the doctor to cure the carious lesion or a complication does not always end the way we would like. Sometimes after stopping the complication appears in the form of increased sensitivity to the cold. To understand the mechanism of occurrence of pain and treatment will try in this article.

The reasons for the increased sensations

Not always, the sensitivity of the tooth after installation of the seal indicates the presence of any complications. If we consider the increase of sensation to cold stimuli in terms of diseases of the tissues to react is only a human tooth. This is possible when the necrotic process hard tooth structures (tooth decay) or the inflammation of the neurovascular bundle (pulpitis). Caries prior to preparation pain noted short sweet and cold. If we consider the complicated caries, namely pulpitis, then the effect of cold stimulus appears pain long term.

To seal doctor tooth begins only after it removes the basic cause of the disease solid tissue or neurovascular bundle. For a start let us examine carious method of substitution.

Treatment of tooth decay which can cause later discomfort

There are several classifications of tooth decay. Mostly use two: the depth of the lesion and the extent of the process.

In correlation to the depth of the lesion:

  • Caries in stage of spot;
  • Initial;
  • Medium;
  • Deep.

According to the degree of the process:

  • Sharp;
  • Chronic.

Doctor all forms except the dental caries in the stage spots, treats with dissection and subsequent filling. Usually tooth sensitivity after a filling is indicated on the background of the abandonment of non-viable infected tissue of the tooth. Most often it occurs when the middle and deep stage of the process.

In order to eliminate the possibility of the re-development of secondary caries, the doctor uses a special solution, which when used will stain the dead tissue of the tooth (the»Caries detector»). However, not every dental appointment you can meet this medication.

Other probable causes that can trigger pain in postcombination period to cold, are indicated for violation of its tactics in terms of treatment of deep caries. If the process is chronic, then this will be indicated visually dense pigmented dentin. The doctor, probing the bottom, it reveals sensitivity. The preparation can be finished in that case, if in sensing the bottom is marked dense pigmented dentin even, the sound will be made from the manipulation krepitiruyuschie.

If the dentin is light, slabomineralizovannaja, soft and doctor for some reason decided not to open the cavity, having decided to reinforce the bottom of the cavity with a calcium-containing substrate, over time the infection from the bottom of the cavity will penetrate the dentinal tubules in the tooth cavity. This penetration will cause the development of a response in the form of inflammation of the neurovascular bundle.

And cause dental caries, pain to cold or heat might eventually be the wrong tactic against chilling. Obligatory condition of preparation is the simultaneous application of air-cooling. Use flow of distilled water from the unit through the gun or the tip together with the installation spirituosa system (saliva ejector) in the oral cavity. If the cooling was carried out insufficiently, the process of preparation occurs heating of the tissue transmitted to polovoy fabric. Thus, even if the average caries can cause the development of pulpitis.

Pulpitis as it can cause pain after treatment

Pulpitis — inflammation of the blood vessels and nerves located in the connective tissue of the tooth infection, overheating, overvoltage. Do not always perform in the treatment of simultaneous removal of tissue (extirpation). In pediatric practice the unformed apical root tip perform amputation (removal of the coronal portion of the pulp), with subsequent filling with a special material. The fact that after sealing a toothache, treated about pulpitis, may give the impression of wrong doing therapy.

Amputation is performed in a short time from the appearance of night pain. Infection of the crown region quickly deployed in the root. And also appear the pain after the sealing can of the inadequate implementation of the hysterectomy removed the neurovascular bundle is not fully or not found one or more channels, which are also the result is not passed.

Pulpitis is treated is not always in one visit. Sometimes two, and a few (gangrenous form). In the case of treatment in a few visits impose a temporary filling. Plombira such material, the doctor tells the patient about the short method of substitution in this way the missing tissues. If the patient draws himself with further therapy, then sooner or later there is a depressurization between the time substance and the tooth cloth. Thus, the tooth after filling, albeit temporary, becomes sensitive to temperature stimuli.

Cured and caries and pulpitis and pain from thermal stimuli is

Sometimes there is that had been on the receiving cavity of carious origin, complications of caries in the form of pulpitis and treated everything was by the rules, and the pain is still there. In this scenario, events, it is recommended to exclude hyperesthesia teeth.

Hyperesthesia — increased sensitivity of tooth tissues to the action of various stimuli. The severity of symptoms is higher during the celebration of microcracks in the enamel tissue or anatomically represented extensions of the nerve tubules of the tooth.

How to diagnose at home and at the doctor’s

At home the patient to realize that a seal is made not, as was calculated by performing simple actions. You can simply drink cold water. Or note that the sealed tooth responds to hot also. When tooth decay will quickly occur discomfort with pulpitis the pain will gradually increase. Sometimes there may be pulsation in the tooth, and the tooth ache is different over time. Voltage polovoy tissue occurs in response to overheating in the process of preparation. If symptoms persist more than 2_3 days is recommended to consult a doctor.

At the reception, the doctor notes the patient’s General condition and the condition of the tissues of the oral cavity. Visualized the viability of marginal integrity, and sensitivity from cold air exposure. As discussed earlier, dental caries, the pain is short-lived, with pulpitis long. Percussion and mucosa without features. Sensing is only performed after the removal of fillings. There is pain on the walls (secondary caries), bottom (deep caries) in one point of the bottom of the corresponding projection at the mouth of the canal of the tooth (pulpitis).

What to do

If the painful events are observed immediately after sealing, it is recommended the use of analgesics with anti-inflammatory and analgesic effect (Ketorol). In case of pain more than 3 days must re-visit the dentist for repeated retreatment of the tooth.


The sequence of actions during the decay at re-admission:

  1. Pain relief;
  2. Removal of fillings, preparation;
  3. Medicated treatment;
  4. Filling.

Tactics of treatment of pulpitis developed, for the first time or not sufficiently treated for the first time:

  • To anesthetize;
  • To remove the seal, to produce a work in the channels;
  • Mechanical treatment of endodontic instruments together with antiseptic irrigation;
  • Fill the canal with permanent material, if necessary, temporary;
  • To apply the seal permanent or temporary.

When applying the temporary filling will need another visit to complete the restoration work.

Prevention or how to prevent disease

In order that the tooth did not respond to cold after a filling is necessary to observe a number of requirements. Recommended planning to visit a dentist every six months or as needed more frequently. To carry out a thorough oral hygiene regularly. Eat right. To avoid excessive stress loads.
