A tooth hurts after nerve removal and canal filling: why and what to do

After removal of the nerve and cleaning of the canals, the teeth can hurt when pressed for both natural and pathological reasons. Under the influence of whatever factors such a pain arises, it is called post-filling.

If the symptom bothers you for no more than 7 days and is weaker every day, there is nothing to worry about. Most likely, it is a completely natural physiological reaction of the body to surgery. If the pain persists for a long time and is very pronounced, you should consult a dentist for repeated treatment.

Why tooth aches when pressed after nerve removal

Many people are afraid to visit dental centers and therefore, if any dental problems occur, they are limited to taking painkillers. However, it should be understood that toothache indicates an infection of the tooth pulp, in which the nerve endings responsible for this symptom are located. Deep caries, pulpitis and periodontitis cannot be cured at home. And the longer the visit to the doctor is postponed, the more painful and longer the recovery period will be after the depulpation - canal treatment.

After removal of the nerve, the tooth should hurt, but slightly and not for long. This pain is called post-filling and is associated with the body's response to surgery. The depulpation procedure is painful, because during it soft and hard dental tissues are injured, and sensitive nerve endings are removed. For the same reason, almost all patients experience pain at the end of canal cleaning. However, in order to accurately determine why a depulped tooth hurts, you must seek help from a dental center.

Canal treatment

Upon completion of the depulpation procedure, it can:

• enamel sensitivity to hot, cold, sweet;
• jaw ache when closing;
• throbbing toothache in the evening;
• general health worsen (headaches, weakness, temperature).

If the acute pain in the tooth that occurred after it was depulped did not go away within 7 days, most likely, repeated inflammation began. In this case, you can not do without the help of a specialist.

The main causes of toothache associated with cleaning the canals

Why can a tooth hurt after removing a nerve and cleansing the canals:

• 

  X-ray dental canals

  The doctor did not conduct the procedure well - in the canal passages there were particles of the dental nerve, which led to sharp pain and an increase in body temperature.

• Poor antiseptic treatment of dental canals or infection after the procedure due to illiterate oral care.
• The appearance of voids under the seal is accompanied by pain when pressed and the formation of abscesses, fistulas.
• The doctor did not take an X-ray and did not notice one of the channels (their number can reach up to 6), as a result of which the infected tissues remaining in them began to rot, and toothache occurred.

Causes of toothache associated with canal filling

Why can a tooth hurt after removing a nerve and filling the canal passages:

• Dentin burn. Occurs when the dentist drills a tooth root for a long time and does not use cooling. In this case, the tooth hurts badly.
• Depressurization of the seal after installation. Most often occurs due to mechanical injury, in which the material comes off the dental tissue.
• Allergic reaction. An allergy occurs to medications and materials used in the treatment of pulpitis.
• Modification of the bite. If the filling is too high, it will prevent the jaw from closing, which will cause pain to begin to feel when biting on the tooth.
• Shrinkage of the seal. Any filling material hardens under the influence of light and may shrink. In this case, the filling begins to put pressure on the dental walls. As a result, cracks appear in the dentin through which air penetrates. If you press on such a tooth, it will begin to ache.

Why does a tooth ache after canal treatment - medical errors

A doctor may be to blame for the inflammatory process that occurs after the treatment of dental canals. It is necessary to contact the dentist again so that he corrects the errors and heals the tooth correctly. Most likely, a decision will be made to put a temporary seal.

Medical errors leading to the appearance of toothache after depulpation include:

• Improper therapeutic treatment of pulpitis - the doctor poorly cleaned the dental canals, as a result of which the nerve, which began to decompose naturally, was not completely removed.
• Puncture of the root - the doctor introduced the filling material beyond the root, which provoked the development of the inflammatory process.
• Poor overlay of filling material - the channels are not densely filled with material, due to which the infection penetrated into them.
• Violation of the technique of filling the canals - the tooth may hurt when touched after treating pulpitis, if the doctor placed the filling outside the apex of the root.
• Inattention of the doctor - during the cleaning of the canals, part of the instrument broke off and remained in the gum, which led to discomfort and the development of inflammation.

Fill beyond the tip of the tooth root

A tooth may hurt after pulp has been removed from it, with trigeminal neuralgia. The disease proceeds in different ways: pain can torment a person constantly or in fits. Only a neurologist can identify and cure it.

Why could a long-healed tooth without a nerve with a filling get sick

A long healed tooth without a nerve with a filling can hurt for the following reasons:

• the doctor could not thoroughly clean the root system, which led to the development of sluggish chronic inflammation;
• the dentist who filled the tooth introduced the filling material beyond the top of its root;
• during depulpation, the canals were poorly washed with an antiseptic;
• the canals are not completely filled with filling material - in this case, acute pain occurs when biting solid products.

How much tooth can hurt after nerve removal

How much the tooth will hurt after nerve removal depends on the individual characteristics of the patient and the cause of the symptom. Fine, pain can persist for two weeks after filling, but only if there is a tendency to a daily decrease in its severity. If more than 3-4 days have passed and your teeth continue to hurt just as much, you should visit your dentist.

Sometimes after depulpation, the so-called phantom pains appear, in which it is painful to press on the crown, cleanse the mouth of the remnants of food, chew food. You may feel that your teeth are whining completely healthy. Phantom pain can persist up to 4 weeks, gradually receding. It is impossible to do anything for its speedy disappearance, you just have to wait out this period.

What to do if tooth ache after nerve removal

In order for a sealed tooth without a nerve to stop hurting, you need to visit a doctor.If symptoms occur due to the development of secondary caries, the doctor will clean, disinfect and seal the tooth again. The cyst that has arisen in the tooth after removal of the nerve and filling of the canals is removed by the dental surgeon. If there is an allergic reaction to the filling material, the binder used for its manufacture should be replaced.

If the dentist claims that the pain caused by removing the filling material at the apex of the root does not require treatment and will go away on its own, consult another specialist. Such pain can persist up to six months and can be easily eliminated in well-equipped dentistry clinics. It arises as a reaction of the immune system to a foreign body, therefore, with a high level of susceptibility of the body, it can deliver terrible discomfort for a very long period.

A condition in which it is painful for a person to bite and chew food (permanently or temporarily) may indicate that the cured tooth is again inflamed. Rinsing the mouth with a solution of salt and iodine will help to reduce the severity of such an unpleasant sensation: five drops of iodine and one small spoon of salt must be added to one glass of warm water. Rinse your mouth about 5 times per hour until the pain subsides. During the treatment you need to remove solid foods from the diet.

To eliminate severe pain, you can use painkillers: Ketarol, Analgin, Mig, Next. It is permissible to take such medicines only after agreement with the doctor.

If the tooth without a nerve hurts when pressed for two days or more, it is necessary to visit the dentist, as the cause of this condition may be improper treatment. The doctor is obliged to unseal the inflamed canals and perform repeated depulpation.

You can reduce the severity of pain before visiting the clinic using warm rinses. An excellent analgesic effect has solutions made from chamomile, St. John's wort, a mixture of soda and salt.

Sometimes a toothache that occurs after removing a nerve and cleaning the canals is removed using physiotherapeutic procedures. For this, phonophoresis with hydrocortisone, fluctuating currents, a helium-neon laser, UHF and microwave are used. These methods of therapy are suitable both for the treatment of natural post-filling pains and for the elimination of various complications.

If you treat your teeth on time, you can avoid many health problems. However, it is necessary to consult a doctor even if it becomes painful to press on an already healed tooth, since a similar symptom often indicates repeated inflammation.
