Local anaesthesia or numbing is done before tooth extraction. This study compares two different methods of numbing molar teeth before extraction. It compares them on the basis of pain during the procedure and on discomfort after the procedure as well. It will help dentists better understand the benefits of the two techniques, and their usage case to case.
