There shouldn't be any pain at all during local anaesthetic, but you'll still feel movement. The injection also shouldn't be particularly painful if done correctly; something like a mild pinch. They can use numbing gel prior to the injection if needed. It also shouldn't affect your alertness.

Are you perhaps a redhead or something else that would give you an atypical response to anaesthesia and pain? Some people do just need a higher dose of local anesthetic, and your dentist should provide it if you're still in pain.

If done correctly!

I was unlucky and it was extremely painful. It also resulted in a very minor permanent facial droop.
