Pediatric dental infection antibiotic evaluation and safety
A child's dental infection needs examination to find its source; antibiotics may support care but do not remove infected tooth tissue.
The short answer
A child's dental infection needs examination to find its source; antibiotics may support care but do not remove infected tooth tissue. Treatment can involve drainage, a filling, pulp treatment, or removal of a tooth, depending on the tooth and the child's development.
How can infection reach the inside of a tooth?
Infection may begin when decay reaches the pulp, the living tissue inside a tooth, or when bacteria enter through a crack or injury. Facial swelling, gum swelling, fever, bad taste, pain, or difficulty opening the mouth can indicate that infection is spreading beyond the tooth.
What should you do when your child may have an infection?
Arrange a dental examination promptly and give the clinician the child's symptoms, medicines, allergies, and medical history. Do not use leftover antibiotics or place aspirin on the gum; the dentist may examine the tooth, take an X-ray when indicated, drain pus, and treat or remove the source.
When is a child’s dental infection urgent?
Seek urgent dental care for tooth pain with swelling, fever, pus, or a child who is unusually tired or unable to eat. Go to emergency medical care if swelling affects breathing or swallowing, spreads around the eye or neck, or the child cannot keep fluids down.
What treatment options should you discuss for the infection?
Ask which tooth is infected, whether the pulp or surrounding tissues are involved, and whether drainage, pulp treatment, restoration, or extraction is needed. Ask how to give any prescribed medicine, what warning signs to watch for, and when the child should return.
Frequently asked questions
Can a child have a dental infection without severe pain?
Yes. A draining abscess may cause little pain while swelling, a gum pimple, bad taste, or fever remains present.
Will antibiotics cure the tooth?
Antibiotics can address infection in selected situations, but the tooth usually still needs dental treatment to remove the source.
