7 Common Causes of Toothache That You Shouldn't Ignore

A tooth is more than just a hard structure for chewing food. Each tooth consists of several layers: enamel, dentin, pulp, and root, surrounded by gums and anchored in the jaw. If at least one part of the tooth or surrounding tissue no longer functions normally, sharp or pulling pain can occur. A toothache is always a sign that something is wrong with the body, and ignoring it is extremely dangerous. In this article, we have gathered seven common causes of toothache that can cause severe discomfort and require professional treatment.

1. Cavities

Cavities (tooth decay) are the most common cause of a toothache. They occur when bacteria in the mouth destroy tooth enamel, causing microscopic cracks and cavities. In the early stages, caries may only manifest as sensitivity to sweet, cold, or hot foods. However, if left untreated, it penetrates deeper into the dentin and the pulp, where the nerve endings are located. At this point, severe pain occurs, especially when chewing or at night. Caries can lead to pulpitis, abscesses, and even tooth loss if left untreated.

2. Pulpitis

Pulpitis develops when the soft tissue inside the tooth, the pulp, which contains nerves and blood vessels, becomes inflamed. This condition is accompanied by severe, throbbing pain that can worsen at night or during temperature changes. Sometimes the pain radiates to the ear, temples, or jaw, making it particularly unbearable. If left untreated, pulpitis develops into tissue necrosis and can be complicated by periodontitis. Treatment usually requires removal of the inflamed pulp and endodontic treatment (root canal).

3. Enamel erosion

Enamel erosion is a gradual thinning of the upper protective layer of the tooth under the influence of acids and mechanical factors. Erosion is not associated with bacterial destruction, but it makes the teeth extremely sensitive over time. It develops because of frequent consumption of carbonated drinks, citrus fruits, wine, and the habit of brushing your teeth too aggressively with a stiff brush. The first symptom of erosion is pain or a sharp reaction to cold and heat, and sweet and sour foods. If the process progresses, the toothache becomes constant. Treatment depends on the stage: from remineralizing therapy to installing veneers or crowns.

4. Cracks and tooth damage

A tooth can fracture due to strong mechanical influences: a blow, an incorrect bite, excessive pressure while chewing, or even a sudden temperature change. A crack is sometimes unnoticeable at first glance, but it can cause severe pain when eating. The pain occurs because bacteria and irritants penetrate deep into the tooth through the crack, reaching the dentin and pulp. Treatment may include restoration, crown placement, or tooth extraction, depending on the depth of the damage.

5. Gum disease

Gingivitis and periodontitis are common causes of toothache. These diseases cause inflammation of the periodontal ligament. Those affected may experience severe pain, bleeding gums, bad breath, and loose teeth. In the early stages, gingivitis is treated with professional teeth cleaning and oral hygiene. However, if the inflammation progresses, periodontitis develops. In this case, the inflammation affects the jawbone, which can lead to tooth loss.

6. Wisdom teeth

The eruption of wisdom teeth is often accompanied by pain. This is because there may not be enough space in the jaw for the eighth tooth to grow normally. As a result, it grows at an angle, presses on neighboring teeth, damages the gums, or becomes lodged in the bone. Such conditions cause not only pain but also inflammation and sometimes the formation of purulent pockets. In difficult cases, the dentist recommends wisdom tooth removal.

7. Sinusitis and referred pain

A toothache is not always directly related to the tooth itself. Sometimes it is the result of a sinus infection, such as a paranasal sinusitis. The upper molars are located near the maxillary sinuses, so inflammation of the mucous membrane can cause a toothache-like pain. In such cases, dental treatment is not helpful, as the problem falls under the purview of an ENT specialist. After treatment of a sinus infection, the pain usually disappears.
