Thanks for requesting for me to answer your question.
Warm salt water rinses are fine, you can do those.
Not being able to brush is normal after a traumatic surgery
, let some times pass and you should be able to brush as usual.
Was the dripping from your nose happening after u drank water or any other liquid? If yes, then it could be an oro-antral fistula
. This is a communication that is developed between the oral cavity
send the maxillary sinuses, due to a surgical procedure like an extraction. This needs to be closed surgically if required.
Regarding the bump on your gum, is it possible for you to upload a photo of that area here? You can either attach the photo directly with your reply or use an external photo sharing site like www.imgur.com and paste the URL of the photo in your reply.
Hope this answers your question. Feel free to contact me again for more information.
