What should I do if my filled teeth are unusually sensitive?

Patient: I had a tooth filling 28 days ago, and the doctor said that it did not reach the pulp, then almost 14 days ago it hurt when I drank a little cold water. Also, it hurts when I eat an apple. The doctor said the pulp was fine, and the symptoms subsided after four or five days. Until now, this tooth cannot eat cold or hot food, but there is no spontaneous pain, this tooth is more in the front, and I have three incisors decayed, one of them has been root canal treatment, I feel so troubled this tooth is still saved? Does it have to be a root canal? Can I still save the pulp of this tooth? Jiang Bizhan: You can consider preserving the pulp. It is recommended to remove the filling, protect the pulp tissue and then observe for 2 weeks before doing permanent filling treatment. Patient: Can I get your number? What day of the week are you available? Jiang Bizhan: I have a specialist clinic on Friday morning, so you can come over and take a look. If you can’t get a number, you can see me in the department and I will give you an extra number. Patient: Hello doctor! My parents asked me to ask. I’d like to know what you said last time about regenerating the pulp. 1. what kind of surgery is needed to do inside the teeth? 2. how long does the treatment take. 3. will there be any after-effects such as kidney injury or other messy things? 4. What was the success rate you mentioned last time before the age of 15? I will come next Wednesday at 8:00 am sharp~. Please! Jiang Bizhan: Hello, does your tooth still hurt! The pulp vitality restoration technology refers to the removal of the original infected pulp tissue after the inflammation of the pulp using the growth factor (imported from the United States, with the US FDA use permit) that has no side effects on the body into the root canal, and through the growth factor to induce the cells around the root to grow into the root, so as to achieve the regeneration of the pulp tissue and restore the vitality of the pulp. This treatment is a new technique recently developed and has a high success rate of over 80% in children and adolescents. However, it is relatively low in adults. Given your age, and the fact that you have root inflammation in your anterior teeth, I think it is a good idea to try this technique. The course of this program is usually about six months, and if you cannot recover within six months, it means that the possibility of pulp regeneration is low and we can also do root canal treatment. Regarding the cost all the imported materials used for pulp regeneration are covered by the hospital, you just need to come for a review in the 1st, 2nd, 3rd and 6th month after the treatment. The procedure you are worried about is actually the exact same as the root canal, which is the extraction of the infected pulp tissue. Since it is important to regenerate the pulp, asepsis is important, so it is done in a sterile surgical suite, not just in a regular outpatient clinic, which is a strict requirement for our operators, so you should not have to worry about it. If there is still something unclear, feel free to ask questions.
