Treatments for Gum Abscesses
If you think your child has a gum abscess, take them to a dentist right away. A gum abscess doesn't go away on its own. If it is not treated, an abscess can damage the surrounding teeth and bones. The infection can even spread beyond the gums, which may lead to more serious problems.
The NHS explains that a gum abscess is treated by eliminating the cause of the infection and draining the buildup of pus. If an object is trapped between the teeth and gums, the dentist will carefully remove it. The pus can be drained through the gum pocket (the space between the teeth and gums) or through an incision in the gum tissue. Usually, this procedure is carried out under local anesthesia, which means that your child will be awake, but the affected areas of their mouth will be numb.
Your child will feel better once the abscess has been treated. They may be prescribed medications to help with any lingering pain, though the NHS does not recommend giving aspirin to children younger than 16. Antibiotics may also be prescribed if the infection is severe.
