I'm getting a tooth extraction of two baby-teeth?!

I'm getting a tooth extraction of two baby-teeth?

I'd like to know two things:

1. I have been reading on answers that some people, when they get their teeth extracted there is a little piece of the tooth left in their gums because the root was broken. Can that possibly happen to me, when they are extracting baby teeth, or can that only happen with adult teeth?

2. When they give you a shot to numb your gums, where exactly do they apply the shot and how much does it hurt?

Please give me some tips before I get theme extracted, I'm kind of scared.

You may end up with a little piece of tooth left behind, but it is pretty unlikely because with baby teeth the roots are already starting to disappear due to the adult tooth pushing from below. For this reason, baby teeth are usually very easy to remove. Before you have an injection (shot) you usually get a numbing gel put on the area first and you should feel almost nothing. You will get a miniscule dose of anesthesia due them extracting baby teeth. You will be in very capable hands so try to relax, maybe wear your IPod or hold someone's hand. Hope this helps!
