I had a bottom molar extracted but the tooth crumbled and half the root was left in the gum - it is still not healed (two months on and my gum is turning grey and I have puss coming out if I put pressure on the gum - pain is mild at the moment and doing salt water washes - I have an appointment in January to have rest of root removed but should I bring this forward?  I would like an implant in the longer term.
Thanks for your query, I have gone through your query. The pain and pus discharge is because of the infection in the left out root piece. Nothing to be panic, consult a good oral maxillofacial surgeon and get it removed. Regrading the implants, to place an implant the tooth should have been removed carefully without losing much bone, right now there is infection in the extracted site, so you might have to wait for another 6 months by placing the graft in the extraction site. I hope my answer will help you, take care.
