What is the cause of toothache

Teeth are a very important part of people's oral cavity and play a very important role. Therefore, if there are symptoms of toothache, it will also affect people's lives, such as affecting people's dining. Many people have experienced toothache, which is related to many reasons. In addition to improper oral care, some dental diseases can also cause tooth pain. You must not blindly judge the disease that causes toothache, but prescribe the right medicine. Toothache is a very troublesome problem for many people, so pain relief must be done well, especially oral care is very important, and attention should also be paid to cleanliness and hygiene. So what exactly causes toothache?

1. Acute pulpitis

It is more common in patients with deeper caries. The bacteria enter the pulp cavity from the caries hole, causing congestion and inflammation of the dental nerve. Toothache is often spontaneous, the pain worsens at night, and is more severe after hot or cold stimulation. The pain may also radiate to the face, temples, and ears. When suffering from suppurative pulpitis, the patient's pain is aggravated by heat stimulation, while the pain is reduced or disappears by cold stimulation.

2. Acute periapical inflammation

Caused by factors such as the development of acute pulpitis or trauma. The diseased tooth presents persistent pain, a floating sensation, and a fear of chewing. The patient can point out the diseased tooth correctly, but tapping the tooth will cause pain. At this time, there is no stimulating pain because the nerve of the diseased tooth has been necrotic.

3. Acute periodontitis

The nature of the toothache is similar to that of acute periapical periodontitis. The diseased teeth not only cause chewing pain and a floating sensation, but also have formed periodontal pockets and loose teeth. The gum tissue may become swollen, painful, and bleed repeatedly.

4. Periodontal abscess

Further development of periodontal tissue inflammation can cause suppurative inflammation. When an abscess is formed, the pain is severe, and a feeling of fluctuation will appear locally after the abscess is formed. After a periodontal abscess forms, the pain can be significantly reduced or relieved.

5. Tooth hypersensitivity

It is often caused by gingival recession, exposed dentin at the neck of the tooth and tooth defects. At this time, cold, hot, sweet, sour and other stimuli may cause pain, but the pain will disappear after the stimulation stops.

6. Food impaction pain

Food can get stuck in the spaces between teeth and cause toothache, which is called food impaction pain.

7. Dry socket

It usually occurs 2 to 4 days after tooth extraction and can cause spontaneous, persistent, severe pain. During the examination, it was found that the blood clots in the tooth extraction wound had a foul smell.
