An abscessed tooth is a tooth that has a pocket of pus in the tissues around it. Pus forms when the body tries to fight an infection caused by bacteria. If the pus cannot drain, it forms an abscess. An abscessed tooth can cause red, swollen gums and throbbing pain, especially when your child chews. Your child may have a bad taste in their mouth and a fever, and your child's jaw may swell.
Damage to the tooth, untreated tooth decay, or gum disease can cause an abscessed tooth.
An abscessed tooth needs to be treated by a dental professional right away. If it is not treated, the infection could spread to other parts of your child's body. A dentist will give your child antibiotics to stop the infection. If antibiotics don't stop the infection, your child may need other treatments.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
