hi, 2 days ago i went to the dentist to get my 4 cavities in the upper front teeth
fixed, they gave me novacains n made me wait for it to kick in, then he started drilling i stopped him cuz i could still feel it. more novacane; then it was painless. after i got home from the dentist the novacaine was pretty much gone. and the areas that he drilled on my teeth are find, but where he put the needle in my upper lip were very painful. i cam feel it into my sinuses and ive had major headaches since.
