Dental radiographs are no problem teeth or hidden pain, may be gingivitis, trigeminal neuralgia, acute periapical inflammation, dentin sensitivity, cryptocleidosis and other diseases caused. 1. Gingivitis: Gingivitis is related to tartar, calculus and other factors. Calcified tartar will form calculus, which accumulates in the mouth and causes some irritation to the surrounding gums, thus causing inflammation, which leads to red, swollen and congested gums, sore teeth and bad breath. 2. Trigeminal neuralgia: the third branch of the trigeminal nerve is called the mandibular nerve, while the mandibular nerve has branches between the lower dental bed and the teeth; the second branch of the trigeminal nerve will have the symptom of pain in the upper teeth; the third branch of the trigeminal nerve will have the symptom of pain, that is, the pain in the lower teeth. Therefore, trigeminal neuralgia can cause tooth pain. 3. Acute periapical inflammation: when the stimulation reaches the periapical tissues, it will cause acute inflammation of the periodontal membrane in the apical part of the root, which is mainly due to the periodontal membrane congestion, vasodilatation, or blood exudation, which will lead to edema, compress the peripheral nerves, and cause toothache. 4. Dentin sensitivity: dentin sensitivity occurs when there are wedge-shaped defects and root exposure problems, causing pain when subjected to hot and cold stimuli. 5. Hidradenitis suppurativa: Hidradenitis suppurativa is a crack on the surface of the tooth, which may cause toothache when subjected to chewing pressure and chemical stimulation. Dental radiographs no problem teeth or hidden pain may also be seen in other diseases, if the symptoms of dental radiographs no problem teeth or hidden pain, persistent and unrelieved, you need to consult a doctor for timely treatment.
