Why does my tooth hurt


Did you get up with a toothache? It is one of the most frequent discomforts a person visits the dentist. The mouth is a highly sensitive area and suffering damage to the teeth can present a very intense pain. Thus, discomfort can spread to other parts such as the head causing further discomfort. The truth is that the visit to the dentist in these cases is always necessary and, in many cases, responds to a lack of oral hygiene or inadequate oral cleaning.


If you are wondering why the grinding wheel hurts, we give you some of the explanations that could answer you.

Hypersensitivity to dentin

Hypersensitivity of the teeth is one of the main causes for which you can feel pain. To understand why you have sensitive teeth it is necessary to understand the different components of the tooth. Our dental pieces contain a softer part inside them known as dentin with two ducts full of nerve endings. The dentin is covered by the dental enamel, however, when it is worn for different causes dental sensitivity. This is the known sensation of pricks in the mouth whenever we consume some food, especially those that are very cold or hot. This happens because as it does not contain the necessary enamel, the liquid or food comes in contact with the nerves of the dentin.

The wear of the enamel that produces the tooth sensitivity is due to different causes:

  • Brushing brushed.
  • Excessive use of tooth whiteners.
  • Consumption of excessively acidic foods.


Another one of the most common causes for which the tooth can hurt is cavities. It is one of the most frequent and known oral affections and is, in most cases, an incorrect oral hygiene. That is why it is imperative to know how to properly brush your teeth.

The mouth accumulates bacteria every time we eat or drink. These bacteria are stored and, if we do not brush our teeth correctly, they end up forming what is known as dental plaque. This set of bacteria adhere between the tooth and the gum, in addition to becoming a dental calculus that damages the enamel of the tooth progressively. This situation causes the enamel to wear away to the point of producing a hole. When this happens, bacteria enter the inside of the tooth and accumulate. This accumulation is causing more and more damage inside the tooth, and when they reach the nerve is when it produces pain.

Pulmonary hyperemia

When a condition such as cavities or hypersensitivity is not treated, the bacteria can reach the dentinal tubules generating inflammation in the pulp. The pulp is a tissue located inside the tooth that contains vessels and nerves. When this area is damaged, it is almost inevitable that the nerve will die. In these cases, it is common to feel the pain in the tooth when biting and chewing food. Damage to the pulp can be mainly two:

Reversible Pulpitis

The dental pulp is alive and, once the bacteria or other invading agents are extracted, the pulp can deflate and return to its normal situation.

Pulpitis irreversible

It occurs when damage to the pulp and nerve inflammation cannot be treated.

Pulp necrosis

The nerve of the dental pulp death. In these cases, it is possible that there are changes in the coloration of the tooth by the decomposition of the pulp tissue. Pulpal necrosis is one of the causes of toothache.

Gingivitis and Periodontitis

Although these oral conditions cause damage to the gums, they can also cause tooth pain. These occur when there is an accumulation of plaque between the tooth and the gum. This accumulation causes inflammation in the gums, redness and irritation. It is important to know that plaque causes plaque, and plaque cannot be removed unless we go to the dentist. When gingivitis is prolonged and untreated it results in a major oral problem known as periodontitis. Periodontitis affects the bone and involves a risk that can lead to the fall of the teeth.

If you notice inflammation in the gums, redness, irritation and bleeding during brushing you should visit the dentist. In this article, we give you some tips to prevent gingivitis.

Dental trauma

Another of the answers to “why my tooth hurts” is a trauma to the tooth. This situation usually results from a blow to the tooth that leads to loss of the tooth. When this happens, the nerve can be exposed causing intense pain in the grinding wheel. In order to eliminate the pain, it is necessary to reconstruct the grinding wheel in order to cover the nerve. A decay that has not been treated can also remove part of the tooth until it reaches the nerve.


Bruxism is the involuntary habit of squeezing teeth causing pressure on the jaw. Prolonged pressure on our teeth can lead to damage to the teeth, but also pain in the ears, headache, or neck pain.

Many people suffer from bruxism at night, so they do not understand why their tooth or jaw hurts when they wake up. This condition is more common in people who suffer from stress, nervousness or anxiety and requires specialized medical treatment. In this article, we help you find out if you have bruxism.
