Q. I am due to have my upper left molar extracted next month at the dental hospital under IV sedation. I was referred there by my dentist due to the tooth being too badly decayed underneath the filling to have root canal treatment on it. As it is causing me little or no pain at the moment I would like your advice as to whether I could wait until it does cause me pain and have it extracted then or would this just make things worse? Also, I am concerned about the gap it would leave behind and would like to know my options regarding this, as neither my dentist nor the dental hospital have discussed this with me. Thank You
