Q. Im now 42, when i was 13 i had 2 top front teeth knocked out by cricket ball. both false teeth are held in the gum by white gold bars. i now keep getting an absess in one of the root canals, and this is so painfull. all my dentist does is give me amoxicillin, which does not help much. is there anything else i could do as sometimes the pain brings me to tears? thanks
