Clinical causes of toothache are many, may be the teeth to deep caries, pulpitis, apical periodontitis, gingivitis, periodontitis, periapical inflammation, dental trauma and so on.
1. Deep caries: When tooth decay reaches deep caries, the deep dentin layer is contaminated, and when hot and cold stimuli as well as food enters into the cavity, the tooth will show symptoms such as soreness and pain.
2. Pulpitis: Pulpitis is mainly manifested as persistent pain from hot and cold stimulation, night pain, radiating severe pain in the teeth, which requires endodontic treatment to relieve.
3. Periapical periodontitis: After tooth decay, bacteria and infectious substances enter the root canal and damage the periapical tissues, which can also cause symptoms of toothache and require root canal treatment.
4. Gingivitis: Inflammation of the gums caused by food impaction, hard object trauma and other factors can also cause teeth to have swollen gums and bite pain and other problems.
5. Periodontitis: Periodontitis is mainly due to plaque and other compression of the gums, clinical manifestations of gum recession, tooth swelling and pain, tooth loosening and other symptoms of discomfort.
6. Pericoronitis: mainly occurs in the mandibular wisdom teeth, mostly due to cleaning is not in place, resulting in food residues left in the gingival sulcus caused by tooth swelling and pain and other problems.
7. Dental trauma: impacts and excessive biting force may cause the tooth to fracture or crack, which may expose the pulp and lead to toothache.
Toothache can also be caused by other reasons, it is recommended to go to the hospital in time.
