I just got back from the dentist, A nerve in my front top tooth was dying because I of boxing, so the only way to save the tooth was to Numb the tooth, giving me 3 injections into my gum, and another 3 into my palat of my mouth, The gun was fine, but the palat was sore as hell. So next thing i see is him sticking these scrapers into my TOOTH, all the way in there, He even took an xray and showed me. My tooth is still numb but he said it won't hurt, sorry Pecker LOL
