Sore tooth after treatment: why and what to do

Patients of dental clinics are often faced with the fact that sore tooth after treatment. Pain can be acute or pull, mild, long lasting. Despite the claims of people far from medicine and dentistry, such pain in most cases is a normal phenomenon associated with the tissue damage of the tooth during drilling and placement of fillings. In some situations pain indicate lack of quality work of the dentist and development of a diseased tooth of a new pathological process. So, what to do if the pain did not disappear after treatment of the tooth? What pain is normal and what is the indication for immediate re-visit to the doctor?

When the pain is considered normal

Any mechanical intervention in the body, whether it be caries treatment or surgery is a violation of the integrity of tissues. In this case there is a violation of the internal structures of the tooth, the removal of tissue. All of this can happen painlessly. Of course, in the process of treatment, the doctor anaesthetises the area in which the intervention is made. Therefore, the teeth on which it was made, start to hurt after a few hours after visiting the clinic.

According to the dentists, pain after installation of the seal can be stored for several weeks. In practice, these deadlines are much shorter. Usually, the patient forgets about the problematic tooth is in 12-24 hours after treatment.

Why sore tooth after treatment? The fact that the pain is a kind of alarm, giving us to understand that the body is not all right, there are some failures, damage. The receptors in pain sensitivity is unable to differentiate between «normal» pain from «bad». It was the intervention, during which they drilled the tooth and remove the pulp — the pain appear.

Note: an important feature of the «normal» pain after dental treatment is her character. Toothache after treatment is characterized by low intensity, aching character, gradual subsidence.

Why «normal» pain persists for several days

The normal human body’s response to mechanical damage is aseptic inflammation and swelling of the affected tissues. Thus there is a local expansion of blood vessels, tissues of the tooth are saturated with liquid, they accumulate in the phagocytes, begin to work other protective mechanisms that will prevent the development of infectious process.

Swelling of tissue is a compression of the nerve endings. Accordingly, the patient complains that the tooth ache after filling. It is important that the pain occurs even in the case of the seal of pain in the affected tooth was not noted.

As healing of the damaged area subsides and the inflammatory process. Accordingly, the swelling comes down, the degree of compression of the nerves is gradually reduced. With it decreases pain. The speed of regenerative processes depends on the individual characteristics of the patient and the morbidity of this intervention.

As mentioned above, the «normal» pain is characterized by gradual subsidence. Strengthening of pain is a symptom of a pathologic process and evidence of improperly performed treatment. Growing pain can occur when injected into the tooth cavity infection and development of bacterial inflammation.

In some cases, the pain is an indication for a return visit to the dentist

A characteristic feature of the pain, indicating ongoing pathological process that is increasing with time, increased intensity of sensations, the spread of pain to other areas of the gums and jaw. If you have similar symptoms you can conclude that any of the following diseases:

  • incomplete removal of carious tissue;
  • chronic pulpitis;
  • damage or improper installation of the seal;
  • improper drying of the surface of the tooth when setting the seal;
  • adolecente inflamed tissue in periodontitis.

This pain can be aching, also occur when biting or to be constant, wear of a throbbing character. In the latter case we can talk about purulent inflammation with abscess formation in the area of the tooth root.

Note: abscesses can occur not only in the form of a localized twitch of pain. With the spread of pain sensation be spilled. While the patient developing General toxic syndrome.

Incomplete removal of carious tissues

With incomplete removal of carious and inflamed tissues pathological process continues even after treatment of the cavity with an antiseptic and the sealing. Such patients first complain of aching tooth. However, such phenomena are usually attributed to the normal pain caused by the swelling of tissues.

In the future the process evolves, the inflammation extends to the former healthy tissue. If the hotbed of anaerobic microflora, she gets ideal conditions for their development, which causes severe inflammation. In the absence of medical aid anaerobic processes for several days lead to the formation of abscess or phlegmon of soft tissues.

Chronic pulpitis

In the process of treatment of caries chronic pulpitis often remains undiagnosed. The filling of carious cavity does not lead to its resolution. The inflammatory process continues to progress, creating aching feeling, after the — causing acute pain.

Note: some patients try to treat the pulpitis, the pulp is heated piercing needle. To undertake independent attempts of treatment using such methods unacceptable. This leads to the formation of chronic foci of inflammation.

In fact, the pulpitis may develop, and because the dental intervention. This becomes possible if the drill of the dentist goes further than necessary. It is damaged the pulp, which leads to inflammation.

Damage or improper installation of the seal

To wrong can be attributed to excessively deep installation of the seal or insufficient depth of her performances. Also in the treatment process, the seals can be damaged by poor quality material. As a rule, in violation of the technology of treatment of patients complain that a tooth hurts when you bite food.

Incorrectly installed seal could be ejected from the seat. Open the carious cavity is quickly subjected to colonization of pathogenic microflora. Microorganisms in the pulp and tooth channels with the emergence of relevant clinic inflammation.

Improper drying of the inner surface of the tooth

When tooth filling, the doctor removes decayed tissue, and then deals with existing cavity with an antiseptic solution. Immediately prior to setting the seal cavity is dried from droplets of the solution, but leave it moist. The presence of drops of antiseptic or conversely, overly dry the cavity leads to insufficient adhesion of the cement.

Improper drying leads to increased pain sensitivity of the tooth and unpleasant sensations that occur in the patient. Such a seal it is better to remove and make a new one. Otherwise it may be lost in the moment to get to the dentist would be impossible.


Adolecente inflamed tissue in periodontitis

Periodontitis can be detected during treatment, the patient’s tooth or to be a result of wrong therapy. Most often disease occurs when damage to the deeper periodontal structures by the dentist’s tools.

In this situation the patient will present complaints, characteristic for this disease: a sense growing up of the tooth, throbbing pain, and later swelling of the gums. In the presence of such symptoms should visit the dentist.

First aid and treatment

If you have a toothache after treatment, should pay attention to the character of the pain. In the absence of the above signs of serious pathological process to stop the discomfort by using pain medications. In the presence of pulsating and intensifying pain, you should immediately consult a specialist.

First aid

«Normal» pain does not require the use of drugs. If there is significant discomfort and the low pain threshold of the patient admission of non-steroidal anti-inflammatory drugs (ketorol, analgin, MIG). To take medication needed for 2-3 days. If during this time the pain was not, it is recommended to undergo radiographic examination to exclude septic complications.

To relieve toothache, you can apply some methods from the category of folk medicine. So, many patients noted a decrease in pain after applying to the sore area of the gum piece of good salted pork fat. This method is often used for the temporary relief of toothache prior to treatment. However, it can be used and for the purpose of relief of pain arising after the filling of the tooth.

The action is considered a way to reduce pain is based on osmotic pressure. The fat, the salt concentration which is sufficiently high, pulls fluid from the inflamed area. This decreases swelling, decreases the degree of compression of the nerve endings, the pain goes away.

If there is evidence of pathological pain and the inability to immediately visit the dentist it is recommended to start treatment with antibiotics. The tool is chosen empirical method. In dentistry the drug of choice often becomes lincomycin, Amoxiclav.


In most cases, severe pain in the tooth after its treatment requires repeated opening of the cavity and thorough antiseptic treatment of canals. With incomplete removal of carious tissue is again processed and thoroughly cleaned. The presence of purulent process is an indication for drainage installation — rubber strips, on which the outflow wound content.

If the patient with purulent process, which developed after treatment of a tooth, long do not seek medical help, he developed a jaw abscess or phlegmon of soft tissues. It’s life-threatening conditions that require full surgical intervention.

Pharmacological therapy is the patient appointment of the following groups of medicines:

  1. Non-steroidal anti-inflammatory (analgin, ketorol) to relieve pain and reduce the release of inflammatory mediators;
  2. Antibiotics (Amoxiclav, lincomycin, azithromycin) is etiotropic treatment. Effect on pathogenic micro-organisms, reducing their number in the pathological focus;
  3. Antiplatelet agents (trental) improve blood circulation, thereby ensuring better supply of the affected area with oxygen and nutrients;
  4. Regenerating means (solkoseril, sea buckthorn oil) are applied topically in the presence of a cut on the gums. Accelerate wound healing.

Note: the use of drugs without the need for treatment of the tooth does not lead to recovery.


Pain in the tooth after treatment in most cases is the result of an error of the doctor. Therefore, to prevent such a development virtually impossible. However, to reduce the likelihood of improper treatment possible. What to do for this?

It should be remembered that the less deep is the carious focus, the less complicated and deeper intervention is required to correct it. So do not put off a visit to the dentist «indefinitely». Ask for help immediately after the defect was found.

If the initial pain arising after treatment for 2-3 days do not decrease, but intensify and become throbbing in nature, you should immediately visit a hospital where you were treated. In case of impossibility of immediate visit to the doctor as a maintenance measure, it is recommended to take an antibiotic.
