Apart from using floss, the other option is to see if you can catch the edge of the husk with a clean fingernail and drag it out. Be careful if the gum is inflamed from trying to get it out with repeated flossing. Alternatively, you can wait 24 hours to see if it dislodges itself or sometimes quickly swishing around a large volume of water in the mouth can help. If it lodged too far under the gum you will need to see your dentist. They should be able to remove it quickly and painlessly. I hope this answers your question.
