When your teeth or gums have an infection, you can end up with pain, swelling or abscess in your mouth. There are a lot of bacteria in our mouths, some are beneficial, while some can injure or damage our teeth and gums. A cavity is basically a bacterial infection of your tooth and gum disease is an infection of your gums. If either of them are left untreated, the infection can spread and sometimes an abscess is formed where the infection is draining. Abscess is usually filled with pus from the infection and it can form as quickly as one to two days after the infection starts. If the cavity or gum disease is not treated, the infection can damage surrounding bone or teeth and can sometimes form a hollow tunnel from your bone to skin called a fistula or sinus tract. You can sometimes see or feel this fistula as a pimple like bump around your gums. If the fistula is draining pus you can sometimes notice a bad taste in your mouth or even bad breath. Pain can occur if this fistula is not draining and the pressure builds up to an abscess. Sometimes if this abscess is left untreated and spreads to other areas, it can lead to serious health problems.
