Why are there nerves in our teeth? And most importantly, why are they capable of producing such severe pain that pain can rarely be compared with elsewhere in the human body?

Types of Toothache and Relief Strategies


We will give a list of alarm signals that, thanks to the presence of nerves, can make us understand that there are problems with teeth and should not hesitate to go to the dentist.

Slight sensitivity, discomfort, close to the pain

Symptom: sensitivity to hot or cold foods and drinks.

This can be caused by beginning caries on one of the teeth, the use of a hard toothbrush and whitening pastes, a recent tooth whitening procedure. In addition, this may be an individual characteristic determined by genetics.

What to do: if the tooth enamel is too sensitive, keep it clean, do not allow the formation of persistent plaque and tartar. Use an extra-soft toothbrush, but not more than twice a day. If more frequent hygiene is required, then use soft rinses. Also, try using fluoride-containing toothpaste intended for teeth with increased sensitivity.

Sensitivity and mild soreness after-treatment of the tooth (s)

Symptoms: food sensitivity and reaction to cold air after dental treatment.

This can be caused: treatment leads to tooth sensitivity due to mechanical effects on the tooth - this is normal.

What to do: this sensitivity can last several days. However, if a tooth has recently been removed or canals of a tooth with severe chronic inflammation have been sealed, a full recovery can take up to two weeks. In this case, the use of conventional painkillers dispensed without a prescription is allowed. If the pain persists or gets worse, consult your doctor.

Pain and discomfort when biting off solid foods

Symptom: Sharp pain when biting or other strong pressure on the tooth.

This can be caused by deep caries, pulpitis, a crack in the tooth.

What to do: go through an examination to find out the cause before the pain worsens and becomes unbearable. If the pain is caused by inflammation of the pulp, then it is necessary to conduct treatment and filling the channels. As for the crack caused by traumatic damage to the tooth, the elimination of the consequences will depend on the depth and location of the crack.

Sharp and prolonged pain when eating cold and hot food

Symptoms: prolonged pain after exposure to hot and cold food.

This can be caused: most likely, this means that the pulp is very sore. As a rule, as a result of deep caries or physical injury.

What to do: it is necessary to diagnose problems in the dentist's chair before the pain becomes serious due to the development of an abscess. The tooth is likely to require canal treatment. Acute and ongoing pain whose source (specific tooth) is difficult to determine

Acute pain and swelling of the gums

Symptom: constant severe pain that does not go away even under the influence of painkillers, swelling of the gums and sensitivity to touch.

This can be caused: there is an infection in the tooth that has spread to the surrounding tissue and bone.

What to do: contact your doctor immediately! In addition to root canal treatment, you will probably need special medications to help minimize symptoms while you are undergoing treatment.


Regarding toothache, the main thing to remember is two things. First, pain is a signal that tells us about serious problems. Secondly - the pain tends to worsen and never goes away like that. It can only temporarily become less acute, but will soon return with renewed vigor. Therefore, postponing a visit to the dentist, at least, is impractical.
