My sister tried to remove her tooth recently from a doctor in luth and they removed the teeth but didn't completely remove it cos it was the last tooth at the upper side of the mouth and little was remaining inside..so it's still paining and the doctor tried and cut one of two places in the gum but still couldn't . So they asked he to come again but she's tired of the stress and also opening her mouth wide for a period of time and the pains too.. is there any recommendations? Like traditional or any other way.. please help and advice . It's just remain small piece of the tooth in her gum and she's scared it might cause more harms or decay. I await your advices and response..thanks
