If a fistula has formed the dentist will trace the source of the infection. He or she will insert a flexible thin piece of material into your fistula. This will make an x ray image and shows the dentist where the fistula leads. Once he cleans the infection the fistula will close on its own.

If the infection started inside the tooth, dentist will make a small hole in the tooth and allows the abscess to drain. After the tooth will need root canal treatment followed by a filling or a crown.If the abscess is very large the dentist will make a hole in the gum so that provides an exit path for the pus or any fluid in the abscess as it will reduce the risk of the further spreading of the infection.

Your dentist will give you a prescription for antibiotics and painkiller after the removal of abscess. These drugs will help the abscess heal and keep it from spreading.
