Open pulp drainage for pulpitis usually costs about $50-100, and if anesthesia is required, a certain amount of anesthesia fee is also required, usually around $20-50, and if block anesthesia is done, it may be around $200-500. If there is severe pain, the nerve needs to be removed under anesthesia and a thorough root canal treatment is done. The cost of root canal treatment is usually charged according to the number of root canals. Regular review is recommended to remove the nerve or to do tooth following treatment. If the inflammation is apical, root canal treatment can be done to remove the lesion completely, and can be combined with oral anti-inflammatory drugs, commonly used amoxicillin, roxithromycin, etc. If the swelling is serious and the pain is severe, you should go to the stomatology department for consultation in time.
