I've just come from the dentist tonight after visit number six over four months. I had an abscess under a tooth, then half the tooth cracked out completely. I'm still in the process of getting it fixed. No pain, though as the nerves are dead. My dentist can drill and ream that tooth and socket with no juice needed. Makes for quicker recovery as no numb mouth. Only two more visits to go and then she'll cap it for good.
Pain from the abscess was worse than any pain I've ever had from dental work, needles or not. So get it done and over with amdkt7 before you get an abscess like mine; it has taken 4 four months to get rid of it to the stage where I can get the tooth restored.
