All India Institute Of Medical Science [AIIMS] — dentist incompetent

My opd number is[protected]. I went to the dental department of aiims for aroot canal treatment and they told me that the root canal is done and i need to come again for getting capping done on 21/11/2019. I went to dr. Vijay for getting my capping done and he sent me to dr. Vandana gupta (Senior resident, unit of conservative dentistry and endodontics) for checking if my gums are good for capping and he mentioned that she would inject a medicine into my gums after giving me anesthesia and numbing my gums. But she injected the medicine straight into my gums without giving me the anesthesia. It was extremely painful. She asked me to come again on 28/11/2019 with few more reports. When i confronted her as to why she didn't give me anesthesia, she gave a stupid smile. This is extremely unprofessional on the part of a doctor who is supposed to make sure that the patient does not suffer pain because of their incompetence.
