You should probably go to a dentist and have it checked out. It could be a severed
salivarySalivary gland tumors duct. The duct may have been damaged and now is
blockedBlocked tear duct and the saliva is pooling in there and causing that jelly bean to appear. If thats the case, they just need to re-open the duct and let the saliva come out or remove it all together. If its on the bottom of mouth, its a minor duct and you won't notice it if they remove it.
