i've had a fair few, and i really dreaded it everytime :S i don't like the needle being stuck into your gums :P but the worst bit is the drilling, the sound and vibrations more than anything :blink: one time, they didn't inject enough aneasthetic on my bottom jaw, they started to drill, and i felt the most painfull feeling i've ever felt in my life :P they had to inject me again, needless to say that's the last time i ever went to the dentists :)
