The structure of the tooth
Externally, the tooth is divided into three parts: crown, neck and root. Crown – the visible part of a tooth protruding above the gum. Neck parts the root and the crown and is under the edge of the gums, the root, respectively, is in the alveoli, and attaches the tooth to the jaw.
The tooth surface is enamel, which protects it from external influences. Underneath the enamel is dentin – mineralized base of the tooth, beneath the dentin is pulp – soft tissue, which contains blood vessels and nerves. The nerves in the tooth as long as there are tentacles of the root, and placed in the root canals.
Tooth nerve looks like a white translucent thin thread of different lengths. Through a root canal, ending apically hole, he goes to the mandibular or maxillary nerve.
Why inflamed tooth nerve?
The cause of inflammation of the dental nerve (pulp and all) is getting an infection in the inner tissues of the tooth. This may be due to deep caries, tooth trauma (e.g., chipped), poor treatment, use of substandard materials during the sealing, the infection through blood defeat of the root of the tooth with intact crown.
Pain when inflammation of the nerve - tearing, as the pulp swells and compresses the nerve. When chewing, the intake of spicy or salty foods, drinking cold or hot water becomes even stronger. This disease cannot be ignored, removing the symptoms with pills, not going to the doctor. First, the nerve may die, but the infection can go into the tissue around. Secondly, the pulp can cause inflammation of the trigeminal nerve, and the pain will spread to the jaw.
How to treat inflammation of the tooth nerve?
Treatment of inflammation of the nerve is determined by the "neglect" of the disease. If the pulp has become dead, you can save the nerve, after removal of the tooth usually darkens. Removing the affected tissue, the dentist usually lays in the tooth various medications that strengthen and restore the pulp and the root. During treatment, he puts a temporary filling, and only at the end of the photopolymer constant.
If the pulp is partially or completely deadened, the nerve is removed, pre - "killing" it with a paste based on arsenic or paraformaldehyde. Then, a cleaning and sealing of the channels assigned to the x-ray to check the quality of the procedures put temporary filling and later constant. Some time after treatment you may feel pain in the jaw, but most often it is caused by irritation of the soft tissues around the tooth.
