Toothache when lying down does not hurt when standing up

Many people have experienced toothache in daily life. Although toothache is not a serious disease, it can have a great impact on the patient's life and physical and mental health. If you pay attention, you will find that when you have a toothache, the symptoms will be lighter when you stand, but will become more severe when you lie down. This is the reason why toothache causes you to be unable to sleep.

Toothache when lying down does not hurt when standing up

Typical symptoms of pulpitis are spontaneous pain, which worsens at night and cannot be localized, and the affected tooth is sensitive to temperature. The pain is aggravated by the low head position when lying flat. In this case, it is probably because the filled tooth was not treated or the treatment was not thorough, so you need to see the dentist again. At present, pulp drainage is required to allow the inflammatory exudate to drain through the root canal, relieve apical pressure, relieve pain, and then gradually treat the disease.

Causes of pulpitis

The main cause of pulpitis is infection. When the hard tissue of the tooth is damaged due to various reasons, bacteria can invade and infect the pulp. Among them, caries is the most common cause of loss of tooth hard tissue. Other causes include tooth defects caused by abnormal tooth development, crown fracture and pulp exposure caused by accidents, which also directly damage the pulp. In addition, in severe periodontal disease, the periodontal pocket reaches deep into the root apex, and bacteria can enter the pulp cavity through the apical foramen or some small branches of the root, causing pulpitis.

Symptoms of pulpitis

1. Acute pulpitis

The main symptom of acute pulpitis (including acute exacerbation of chronic pulpitis) is severe pain, which has typical clinical characteristics.

Severe pain occurs suddenly without any external stimulation. The pain has a process of persistence and relief, so it has the characteristics of paroxysmal attacks or paroxysmal aggravation. Secondly, it is night pain. Patients often have difficulty falling asleep because of toothache. Thirdly, temperature stimulation will aggravate the pain. Eating hot or cold foods can stimulate pain or make the pain more severe, and people often dare not brush their teeth with cold water. In the late stage of pulpitis, it also manifests as "hot pain, cold relief". Heat stimulation will produce severe pain, and patients often temporarily relieve the pain by gargling with cold water. When the pain occurs, most patients cannot clearly point out the location of the affected tooth, and the pain often radiates to the upper and lower teeth or head and face on the same side of the affected tooth.

2. Chronic pulpitis

(1) Chronic closed pulpitis

There is no obvious spontaneous pain or occasional dull pain. However, almost all patients have a long history of pain due to cold or heat stimulation.

(2) Chronic ulcerative pulpitis

There is usually no obvious spontaneous pain, but patients often complain of severe pain when food is stuck in the affected tooth cavity. Another typical symptom is severe pain when cold or hot stimuli irritate the affected tooth.

(3) Chronic hyperplastic pulpitis

Generally there is no spontaneous pain. Sometimes patients may complain of pain in the affected tooth or bleeding when eating. Therefore, they dare not chew food with the affected side for a long time.
