[|Human|] Hi -  i split the piece of gum between #20 and #21. i saw my prosthodontist yesterday, and he told me to use Chlorhexidine twice a day. He said not to rinse or brush afterwards (as he did in the past cause it can cause tooth discoloration. My concern is with the tooth discoloration.  Is there an alternative solution of any kind so i heal the area without using Chlorhexidine? I greatly appreciate your help and wish you a happy holiday season. Many Thanks,Priscilla
[|AI|]  Hi. Thanks for the query. Well, you can use oral gel like Metronidazole that can be applied precisely over the injured area of the gum. You should keep spitting the saliva and do not swallow it. It will not cause any tooth discoloration and will help in preventing infection and heal the injured gum. Also do warm saline gargles and take soft diet. Avoid any hard and spicy foods. Use a soft toothbrush to brush your teeth to avoid injury to the gums. Hope this helps. Regards.
