Dental anesthesia is one of the most commonly performed procedures in clinical dental practice and is essential for ensuring pain free treatments and improving patient experience.

Despite the high efficacy and predictability of current anesthetic techniques and agents, certain clinical situations may result in inadequate anesthesia, potentially compromising treatment outcomes and causing patient discomfort.

The aim of this presentation is to review the main dental anesthesia techniques and discuss recent advances aimed at improving their clinical effectiveness. Particular emphasis will be placed on the inferior alveolar nerve block, highlighting key anatomical considerations for accurate needle placement and optimal anesthetic deposition.

In addition, complementary and alternative techniques will be explored, especially in complex cases where conventional approaches may fail. Commonly used local anesthetics in dentistry will also be reviewed, focusing on their advantages, limitations, and clinical indications.

Finally, practical, evidence-based tips will be presented to help clinicians optimize the success of dental anesthesia in daily practice.
