Root canals are the beginning of the dental implant or prosthodontic process. You cannot change your smile for the better if you have not first asked your dentist what they can do for you. Root canals are a simple surgery where the dentist must remove a tooth and the root/nerve. The recovery process for your root canal requires that you have gone home with someone who can help you. You will have a bit of bleeding once the procedure is over because the root was removed from your gum.
