Tooth abscess
A dental abscess is a collection of pus that can form inside the teeth, in the gums, or in the bone that holds the teeth in place. Its caused by a bacterial infection.
Symptoms of an abscess in your tooth or gum may include: an intense, throbbing pain, pain that spreads to your ear, jaw and neck on the same side as the affected tooth or gum, pain that's worse when lying down, etc.
Dental abscesses are treated by removing the source of the infection and draining away the pus. Depending on the location of the abscess and how severe the infection is, possible treatments are used like: removing the affected tooth, root canal treatment, etj.
Your mouth is full of bacteria, which form a sticky film on your teeth called plaque. If you don't keep your teeth clean, acids produced by the bacteria in plaque can damage your teeth and gums, leading to tooth decay or gum disease .
You can reduce your risk of developing dental abscesses by keeping your teeth and gums as healthy as possible by use floss or an interdental brush at least once a day to clean your teeth, brush your teeth with a fluoride toothpaste twice a day, avoid rinsing your mouth with water or mouthwash after brushing, etc.
