Whether or not root canal treatment can be reimbursed by medical insurance depends on different local medical insurance regulations, and cannot be generalized. 1. For oral treatment, root canal therapy is very widely used in clinical practice. When there is pulpitis or apical inflammation, it is necessary to carry out root canal treatment, so, root canal treatment is a clinically important means of treatment of toothache. 2. Whether root canal treatment can be reimbursed by the medical insurance or the reimbursement rate is different according to different local medical insurance policies. Therefore, patients are advised to find out the local health insurance policy and the amount of reimbursement before treatment. At the same time, it is recommended that patients undergo root canal treatment in the dental department of a regular hospital to prevent unnecessary adverse consequences. For specific medical insurance reimbursement matters, please consult the hospital’s medical insurance office.
