What are the causes of sudden toothache

There are many reasons for toothache, such as caries, periodontitis or pulpitis, etc. It may also be caused by sudden toothache due to anxiety, inflammation, etc. Toothache can be very painful and can seriously affect study, work and life. Many people will suddenly have toothache in life. So, what are the causes of sudden toothache? We need to understand the causes of sudden toothache so that we can take appropriate measures when we have sudden toothache.

1. Tooth decay

The occurrence of dental caries can also cause toothache. Initial caries usually have no symptoms. When the caries cavity becomes larger and deeper, toothache will occur when eating. The pain will be aggravated when eating sweets or overly cold or overheated food. You can brush your teeth with warm water at this time, but the most effective treatment is to fill the cavities.

2. 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. This is the reason why adults often suffer from toothache.

3. 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.

4. Tooth Trauma

If you accidentally fall, get hurt, or bite sand while eating, your teeth may break or crack, causing toothache. You can take anti-inflammatory and analgesic drugs first.

5. Pericoronitis of wisdom teeth

Difficulty in the eruption of wisdom teeth (impacted), coupled with poor oral hygiene, causes inflammation, swelling and pain in the tissues around the crowns.

6. 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.

7. 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.

8. 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. This is also the reason why adults often suffer from toothache.

9. 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.
