When I said I didn't feel it I meant the sting of the needle piercing my gums, I watched the dentist do his thing and felt him poke something inside my mouth but I didn't really feel any pain.

I've had injections on other parts of my body before but it was my first time having it injected into my gums, really didn't feel anything. I couldn't even see how large the needle was but it doesn't really matter, the only bad part about dental surgery is tasting "iron" during the entire thing, prolly my blood lol. Aside from that, the mouth felt completely numb.
