These situations should be timely contact with the doctor to deal with, otherwise there may be serious consequences, the following detailed description: 1, toothache Teeth will appear after the force of mild pain, the specific performance of soreness and weakness, there will be pain when biting, not biting pain is not obvious, there will be no hot and cold stimulation pain and pain aggravation at night. If the tooth has persistent pain, throbbing pain, hot and cold stimulation pain or one of the night pain, you must contact the doctor as soon as possible to deal with the possible causes of hidden tooth decay, occlusal trauma, tooth trauma or excessive force, and need to deal with it in time. 2.The part of the wire that easily sticks to the mouth is the end of the upper and lower jaw wires, usually because after the crowded teeth are aligned, the original curved wire becomes straight and the end will become longer. In this case, you can wrap it with cotton or mucous film protective wax, and then contact a doctor to cut off the overgrown wire. If the site of the ligature is in the front teeth, it may be caused by the end of the ligature wire of a single tooth buckling, at this time, you can use chopsticks at home to lightly press the end of the ligature wire towards the tooth surface, or contact the doctor for follow-up treatment. 3, brackets fall off brackets or buccal tubes and other orthodontic devices are used special bonding agent stuck on the tooth surface, normally speaking, it is not easy to fall off.
