I've had severe toothache for a week now and the pain is now going into my ears and around my jaw. i am petrified of dentists am i able to be sedated?

Yes: Sedated for the procedure, not the examination. See a dentist who does sedation dentistry, if he feels the tooth can be saved, he can offer oral sedation (pill). If the tooth has to be extracted, you can be put to sleep by an oral surgeon.

Call a dentist ASAP: Any other treatment is a temporary relief. A tooth pain won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. With the profound local anesthesia and IV sedation you will have no recall of the events of the dental treatment or experience any pain.
