Neurectomy of tooth

1 First, tell yourself how to check a cracked tooth: drop a little iodine on the crown surface of the tooth, and then gently wipe it off. If there is cracked tincture of iodine, it will penetrate into it for linear coloring. 2 Causes of cracked teeth: Traumatic chewing injury (biting hard objects) and dental caries can all cause cracked teeth. However, cracked teeth are similar to many other dental symptoms, so you should pay attention to the differentiation: for example, dental pulp allergy (transient pain will disappear in a short time due to hot or cold stimulation or chewing), periodontitis (often accompanied by swelling of adjacent mucosa, which can cause lymph node enlargement on the same side of mandibular posterior teeth), and 3 treatment mainly depends on the degree of cracked teeth. If the cracked tooth runs through the whole tooth, it is recommended to remove it, because the tooth component is mainly hydroxyapatite. Limestone is impossible to heal. If it is a semi-crown fracture, root canal treatment should be done first and then crown sleeve should be used to protect the affected teeth. Note: crown restoration can only be done after treatment, otherwise it will pit you. After root canal treatment, the tooth itself will lose its nutritional supply because there is no pulp. After a period of time, teeth will turn black and become brittle. Without teeth, the pulp will naturally feel nothing, so some patients will complain that their teeth cannot be chewed. Five root canal therapy is the premise of treating moderate and severe cracked teeth. At present, there is no better method for this kind of dental disease. Of course, if the fractured tooth is only confined to the crown, you can also choose to remove only the crown pulp and keep the root pulp, which will cause less damage.
