Hi doctor, I had done a root canal for an upper tooth in 2010.  Now all the cement has fallen off. And the tooth broke in two pieces. And I can see skin has grown in the middle of the tooth. Some times when I eat  food it bleeds a little there. I'm having cold from few days because I had to use very cold water and dust exposure. I thought of extracting the tooth after my cold gets alright. But today when I brushed my tooth it was bleeding tooth much there. After little while it stopped bleeding. I still have cold and cough and facial pain due to cold. I cannot extract now. Could you say something on this.
