Doug Leone, a prominent figure and former managing partner at Sequoia Capital, drew public attention after recounting his decision to undergo dental procedures without anesthesia.

In an interview on the ‘David Senra’ podcast, Leone explained that he requested a dentist drill without numbing agents to avoid potential side effects of anesthesia before a meeting, describing the choice as a personal test to see if he was a ‘badass.’

Following these comments, Leone’s decision to undergo a root canal without local anesthetics like procaine sparked debate. He described the experience as physically intense, noting he was sweating profusely by the end of the treatment. In response to the story, dental professionals and the American Association of Endodontists noted that modern techniques are designed for patient comfort and emphasized that root canal treatments should not be used as tests of physical endurance.
