When I ate hazelnut, my teeth were damaged and I didn't dare to eat. I went to a top three hospital for root canal treatment. I was treated seven times for nearly two months. Every time I came back after dressing change, I felt a little stuffy and had pain all the time. I asked the doctor, and the doctor said it was normal. The day before yesterday, the doctor blocked my teeth. I didn't make the braces. There was pain in the buckle before blocking. I asked the doctor if it was apical periodontitis. The doctor said no, and that my tooth might have cracked. Now the key is that I don't feel comfortable eating, and it's painful to buckle. The doctor said that I should be observed for a month. So I want to know what to do with tooth pain after root canal therapy. Let's talk about how tooth pain occurs after root canal therapy.

How can the tooth ache after root canal treatment

First: my friends must pay attention to the anatomy of the teeth, that is, the tip of the molar is too high and too steep. When molars chew food, it is not a vertical involution of upper and lower teeth, but a multi-directional crushing and grinding process participated by masticatory muscles. The masticatory force required should reach tens of kilograms. If the tooth tip is too high and too steep, the masticatory force can produce a greater component force on the teeth, making the teeth easy to split. Such teeth often have imperceptible cleft before treatment.

Second: friends must know that filling materials, such as silver mercury, have a large coefficient of expansion, which can also cause tooth splitting. The nutrition supply of teeth mainly comes from the dental pulp. After root canal treatment, the dental pulp is killed and removed, and the teeth that lose the nutrition supply become fragile. Even if they eat ordinary food, they may split, which is the same as the reason that a branch is easy to break. If any of the first three factors are present at the same time, it is easier to split.

Third: friends must pay attention to that if only a few teeth split, most of the remaining teeth are stable, without occlusal pain, and there is no apical lesion on the dental film, the active part of the split can be pulled out, and then the crown can be restored. If the split in the center of the teeth, activity is more obvious, plus swelling and pain and other symptoms, generally must be removed. Three months after extraction, implant denture, removable denture or fixed denture can be selected according to the indications.

matters needing attention

Friends must understand that the split just occurred, the part in the center of the tooth, two parts are not loose, no pain, no swelling gums, no occlusal pain, no lesions in the apical part of the film, can be two parts of the tooth split ligation firm, do crown repair. This method can't guarantee 100% success. It's very troublesome for doctors to operate. Not all doctors are willing to do it.
