Why The Dentist Makes You Laugh Uncontrollably 😂 Why is this girl laughing uncontrollably while getting dental work done? 😂 It looks like a comedy show, but it is actually a brain trick! This is Nitrous Oxide, famous as "Laughing Gas." The moment you inhale it, the fear centers in your brain shut down. You feel as light as if you are floating on clouds. ☁️ You stay awake, but all the stress and pain completely vanish. #shorts #dentist #laughinggas #funny #medical #health #teeth #science #nitro

Going to the dentist is no joke, unless you inhale some laughing gas, then it's pretty hilarious! | The Fantastic Family Time Machine
