Dentists won't pull a tooth that has an abscess under it as the Injection that anaesthetises the area and makes it numb (Novocaine etc) does not work if an abscess is present, you need to go to the doctors or the in patient part of a hospital and they will gives you a weeks course of Amoxicillin (anti-biotics)to get rid of the abscess, only once the abscess has gone will a dentist pull the tooth, that's what happened to me anyway.

Uhuh... except that none of that is correct.

He did mention if i left for a week longer it would have started to eat away at my teeth then into the jawbone & eventually lead to blood posioning.

No way of telling if it would've been a week.

And since you're getting it treated, here's a tidbit - dental abscesses are a common cause of cardiac surgery.
