I'm a grown up Mum and petrified of the dentist - haven't been for 20 years until 5 days ago - currently in pain and have been urgently recommended to Queen Alexandras Hospital in Portsmouth (Southampton?) for top, left, back extraction under GA - I'm being admitted as an excessively nervous patient - I had a bad experience 20 years and never went back.... Can anyone allay my fears - I worry that i might not wake up and my son will wonder where I am.
