Gumboil, known medically as Parulus is defined as a drainage point for abscessed teeth. This is a dental infection that occurs around the root of the tooth. It can be caused by a number of reasons, the most common among them being tooth decay, gum infections or a failed root canal. Gum boil appears as a small red bulging in the gum which when pressed drains out pus or occasionally blood. This condition is very painful and may also cause fever, swelling of the face and earache. The patient may experience a foul salty taste in his mouth and bad breath due to the pus draining out.''
