Patient Question:Disease:Hot and cold tooth sensitivity, pain, root canal treatment; wisdom tooth blockage Description:I am female, 23 years old. In June 2014, a resin filling was done in Anhui for the upper left sixth-aged tooth. There was no sensitivity and no pain before the filling, but the cavity was large and the caries time should have been about 10 years. After the filling, the cold sensitivity was serious, but the heat sensitivity was a little bit weaker, chewing was painless, and I was used to chewing with my right side. In the winter of 2015, the weather in Beijing was cold, and I started to be sensitive to cold wind. On December 23, 2015, I started to have toothache and swollen gums (my period started, I have irregular menstruation and come once every few months). December 30 Jishuitan Hospital oral, did the ice strip test, a certain place cold sensitive stimulation is heavy. Percussion no pain; current test when the pain is not as strong as the cold stimulation. Dental film was taken and the doctor said that the pulp was not injured. Observation was recommended (symptoms gradually decreased on January 1 and the period gradually ended). January 5, 2016 dinner, painful hot water stimulation. January 6, 2016 night, cold and woke up in pain during sleep. January 7, 2016 morning, Tong Ren Hospital for glue stick heat stimulation, painful, root canal for the first time. Now the tooth is more painful, painful to percussion but no longer sensitive to hot and cold water. Hope to provide help: 1. All my crowns are relatively short, the doctors are saying to root canal finish need to do braces. I don’t use my left side to chew food and I don’t want to wear out my teeth, can I just fill my teeth with glass ionomer without braces? 2.The dental film shows that my caries has not reached the pulp, but it has been sensitive, should I do desensitization treatment first instead of root canal, will it be over-medical now? 3.The dental film shows that my upper left wisdom tooth is blocked, is it necessary to extract it? 4. Is it normal that my tooth is painful when I knock on it and also when I don’t touch it? 5. The reason for my root canal is that I have checked that the inflammation of the pulp may be caused by the abnormal hormone level during my period. Will I have toothache during my period or pregnancy in the future? Are my worries superfluous? The first root canal was done in the morning of January 7, and I started taking it at noon, just after the first one. Drug name: auxin tooth pain anti-inflammatory granules Dosing instructions: 2 times a day, one sachet at a time. I started using it on December 31 and drank 5 sachets. During the same period, I took artificial cow’s yellow metronidazole capsule, cow’s yellow detoxification tablets (these three drugs are self-purchased, not prescribed by the doctor) Taking until January 3, the tooth pain reduced to a relatively mild, but not completely eliminated. Yang Yang, Department of Stomatology, Beijing 301 Hospital, replied: 1. Whether the crown needs to be made after root canal treatment depends on the size and resistance of the crown defect after root canal treatment. If it can be filled directly, it is also recommended to use a more wear-resistant resin material. 2.According to your description, the pain woke up on January 6, belongs to the symptoms of pulpitis, desensitization can not solve the problem, de-pulpal root canal treatment is the right choice. 3, whether the wisdom teeth need to be extracted, depends on the situation in the oral cavity, such as completely under the gums, no symptoms, then you can not deal with. If part of the gingiva is exposed and often inflamed, it needs to be extracted. 4.It is a normal symptom in root canal treatment, if the symptom is more serious, it needs to be treated in time for consultation. 5.After the perfect root canal treatment, the problems you are worried about will not usually occur.
