So I went to the emergency dentist last week for abscess on my gum . He did a X-ray , found the infection from my front tooth . He performed root canal , gave antibiotic in my tooth . Thought all would be well and iv finally got it sorted , fast forward to today ! And it's back ! Yellow pus inside , it's back but not as big as last time . He did say to keep using salt water , how the hell do I revolve this ? Any remedies to cause drainage on its own ? I can't go to the dentist again as no child care and really cannot afford it . I'm in no pain whatsoever , it's just annoying to have lol . I thought this would of been over with after visiting the dentist! Help . Also I don't think he drained it just did the root canal
