[|Human|] I have been on pain medications for several years now for chronic pain and nerve pain down my left leg. I actually am a real pain patient - not some junkie.  I need the medications to have some small part of my life. I have noticed of late that what few teeth I have left (I have two partials in my mouth) have black all around them at the gum line.  It seems that it was there before I knew that it was (I believe that it came on quickly before I checked my teeth in a mirror).  Could you guess what this could be?  I am horrified that I will need to have them all extracted and have to go to full dentures.  I would appreciate some small answer.  Thank you
[|AI|]  Thanks for your query, I have gone through your query. The black discoloration over the teeth can be because of stains secondary to coffee, tea, or smoking(if you are a smoker) or it can be secondary to decayed teeth. Nothing to be panic, consult an oral physician and get it evaluated. If it is because of stains then get the teeth cleaned by scaling and root planing. If it is because of the decay, then get the teeth restored with tooth color restoration material like GIG or composites. I hope my answer will help you, take care.
