Do teeth extractions hurt?!

The injection you have will sting a bit, like a small pinch but the anaesthetic will start to work very quickly, sometimes mid-injection you will realise you feel nothing!
As others have already commented you will feel no pain but an unusual pressure, as they are to make spaces for braces they will probably be the 4th tooth along in each quarter of your mouth and these teeth are SO simple to remove.
You have Absolutely nothing to worry about and it will be over a lot quicker than you think.
I hope that has helped a little.
Be brave and stop worrying

Im a dentist.

I had my tooth extracted last year, it hurts only a little bit when they inject your gums.

Then all you feel is the pressure being applied while the dentist pulls your teeth out.

Afterwards its a little uncomfortable for a few weeks and you have to be carefull what you eat and I'd recommend strong pain killers, as you can experience some gum ache and sensitivity on the remaining teeth around the extracted tooth

I had to get 2 teeth extracted for my braces and i was so scared LOL.
But honestly its fine, the only part that hurts is when the put the needle in your mouth but its nothing too bad and you dont feel them pull your teeth out at all. Then you just have a numb mouth for a while haha :)

You'll feel pressure as the teeth are being extracted, but you'll feel no pain because you'll given novocaine before hand, I was scared too when I learned that I had to get my wisdom teeth extracted.

I think it would hurt; if you weren't numbed for the pain or put under local anasthetic. It may be uncomfortable afterwards...

You don't feel a thing after the injection.

Not at all. They numb you up beforehand so you won't feel any pain.
