<s>[INST] I Have A Huge Boil At The Top Of My Mouth. It Sits On The Second Tooth At The Back. It s A Gum Boil And It Hurts Really Bad. I Can t Eat And I Can t Close My Mouth All The Way Or It ll Start To Hurt. What Do You Suggest I Should Do About It While At Home. P.S ( Their Always In My Mouth, Everytime One Disappear, Another Comes In A Different Spot. ) When I Go To The Dentist They Give ME Different Kinds Of Medicine And The Boils Will Disappear For A While And Comes Right Back. I ve Been Having This Same Problem For About 4 Years Now. I Need Help. [/INST] Hi..Thanks for the query..As per your complain a gum boil can occur as a result of infection and trauma in gums leading to stuffing of bacteria deep into the gums leading to formation of a pus filled bubble known as a "GUM BOIL"In case of a gum boil you should get the professional cleaning of the gums and teeth done followed by a course of antibiotics like amoxicillin and metronidazole and gum paint can help..But in case if the boils are recurring and there is change in location of the gum boil everytime then you should get an evaluation done for canker sores as well as herpatic cold sores as recurrent gum boils at varying sites on gums is not a very common finding..As in case of canker sores or cold sores the line of treatment can be totally different as of the gum boil..Hope this  helps..Regards.. </s>
