Symptoms of nerve entrapment

The tooth may look very simple on the surface, but inside it is made up of very complex structures of nerves, blood vessels, and supporting tissues such as the gums and bones, all of which together maintain the structure and function of the tooth. The internal parts of the teeth include cement, blood vessels of the nerves, dentin, pulp, etc.

Tooth damage has several stages. In the early stages, the damage is apparent and generally does not cause pain. For this reason, you should always pay attention to the appearance of your teeth and if you see any changes, follow the cause. But if the damage deepens, it can penetrate the nerves of the teeth and cause severe pain.

Stay tuned with StrAIberry for more information on the symptoms of nerve entrapment.


Tooth nerve entrapment

Enamel is the outermost layer of the tooth that is in direct contact with food. Beneath the enamel and after the hard tissue, there is soft tissue where nerves and blood vessels are located, called the dental pulp. The pulp starts from under the crown to the root of the tooth. This tissue is very sensitive and can be easily damaged by contact with food, so it is covered with a hard layer and protected.

If the enamel and dentin are damaged and cracked, it can open the way for bacteria and nutrients to penetrate the innermost parts of the tooth. If this failure is not treated in time, it will gradually deepen and reach the dental pulp. Cracks on the teeth are a hotbed for bacteria to accumulate and grow. The presence of bacteria in these areas also exacerbates tooth damage, as their metabolites destroy tooth tissue.

As the superficial damage to the tooth deepens, it reaches the pulp, where nerves and blood vessels are located. As a result, food and bacteria can easily reach this area and cause problems and damage to the tooth roots. The root of the tooth becomes inflamed due to exposure to external factors and causes severe pain in the tooth.

Symptoms of tooth nerve entrapment

When the damage to the tooth becomes very deep and reaches the root, the nerve of the tooth gets involved, which causes more severe pain and harm if not treated in time. Damage to the nerves of the teeth always manifests itself with symptoms. See your dentist as soon as you experience these symptoms.


  • Pain

Pain in all parts of the tooth always indicates a problem. Of course, not all toothaches indicate nerve entrapment. In some cases, root canal problems do not even cause pain, and other factors indicate root damage. The type, nature, and location of pain caused by root damage are different from other dental injuries.


Type of pain

Nerve entrapment pain is rapid and severe. This transient pain becomes more severe and lasts longer as the nerve damage increases. So that it gradually becomes a vague and longer pain.


Characteristics of pain

Pulsating pain in the teeth indicates nerve damage.

The severity of the pain can change with posture change, such as standing, bending, lying down, etc. The pain from nerve damage usually increases when bending.

Sometimes the injury causes so much pain that it interferes with the patient’s sleep.

Profile of pain

Nerve entrapment pain may be sudden. That is, it is created spontaneously without the need for any stimuli. Sometimes this pain occurs in response to external stimuli. External stimuli include pressure from chewing food, biting, clenching teeth, hitting teeth, or changing temperature. Also, sugary foods can greatly increase this pain.

Spontaneous toothache is usually transient. In the more advanced stages of the injury, the pain is chronic and long-lasting, making it very difficult for the patient to bear.

Pain caused by a response to a stimulus in nerve entrapment usually persists for a while as the stimulus disappears. Over-the-counter painkillers can relieve some of this pain, but this is not a permanent treatment and starts again when the effect wears off.


Location of the pain

One of the problems with teeth is that the patient cannot accurately identify which tooth the pain source. Damage to the tooth nerve transmits pain to the surface that occurs in the gums. This type of pain is called recurrent pain. This means that the source and location of the pain are different. For this reason, after experiencing painful teeth and gums, see a dentist to identify its main source and choose the appropriate treatment.


  • Sensitivity

The next thing that can indicate dental nerve entrapment is the tooth sensitivity to cold and heat. A common type of tooth sensitivity is to temperature changes caused by hot and cold drinks. Occasionally there is a sensitivity to sugary foods.


  • Infection and swelling of the gums

Swelling is one of the most noticeable signs of inflammation. Depending on the stage of nerve entrapment, this swelling can be very slight, manifesting as a red area with tenderness. In case of severe nerve entrapment, the infection involves large, palpable bumps that can be easily detected.

Inflation location

The location of the swelling varies depending on the degree of inflammation. When the nerve entrapment is severe, the swelling spreads to the face and neck. In mild conflicts, the accumulation of inflammatory agents is near the tip of the tooth root. Occasionally there is a pimple on the side of the gums. It is important to note that these bumps are not always painful and can sometimes be painless. If the accumulated mass finds a way out, it can cause a bad taste in the patient’s mouth or bad breath.


  • Change in tooth color

Sometimes nerve damage causes the teeth to darken and change color. This indicates damage to the internal structures of the tooth that, if left untreated, can lead to tooth loss.


Common treatments for toothache pain

You can see a dentist to treat nerve entrapment like other dental problems. A filling is commonly used to treat nerve involvement. In cases of high involvement, the tooth is denervated.


  • Filling

The filling is the most common form of tooth restoration. In this type of treatment, the damaged tooth is filled with cement. During this operation, the area around the tooth is anesthetized, the decayed part of the tooth is removed, and special dental cement is used to fill the damaged area. This treatment prevents nerve injury by external stimuli.

  • Root canal

This is a more severe dental procedure used when severe tooth decay results in pain. During this procedure, the damaged nerve, and the pulp of the damaged tooth, is completely removed, and then the area is cleaned and sealed. As a result, you can use your teeth without feeling pain.


You can also use toothpaste for sensitive teeth to minimize damage to the teeth. The best way to prevent dental problems is to follow a proper care routine that includes brushing, flossing, and mouthwash. StrAIberry app provides you with some services for a proper dental routine.
