Q. am just wondering how effective sedation is? i am very scared of the dentist but after having terrible toothache for a week i had no choice but to go he told me the tooth needed taking out and i calmed myself enough for him to inject the gum and loosen the tooth then after 5 attempts of removing the tooth told me he could not do it i was sent home in agony and shock now i know i cant try this again without sedation..or could i even be put to sleep?,
