Dental abscess
Overview
Dental abscess affects the mouth, teeth, ears, hearing or vision. Early assessment can protect comfort, communication and learning.
This guide provides general education and cannot diagnose an individual or replace professional assessment.
Signs and symptoms
Possible signs include pain, swelling, discharge, reduced hearing, ringing, squinting, blurred vision, feeding discomfort or changes noticed during schoolwork.
Age, development, duration, severity and impact on daily life help determine what the symptom means.
Causes
Infection, fluid, wax, developmental differences, refractive error, dental decay, irritation or normal infancy changes may contribute.
Risk factors
Family history, prematurity, repeated infections, limited screening or dental care and some medical conditions can raise risk. Risk factors do not confirm a diagnosis.
Diagnosis
A clinician, dentist, optometrist or audiologist examines the relevant area and may perform hearing, vision or dental tests.
Treatment options
Treatment may include observation, pain relief, dental care, glasses, patching, hearing support, medicine or a specialist procedure.
Home care
Follow cleaning and treatment advice, attend screening and avoid putting objects or unadvised products into the ear, eye or mouth.
Prevention
Regular dental and sensory screening, twice-daily brushing, protective equipment and early review of concerns prevent avoidable harm.
Possible complications
Untreated problems can cause pain, infection, reduced vision or hearing, sleep disruption and barriers to speech or learning.
When to seek urgent medical care
Urgent dental care is needed for facial swelling, fever, spreading redness, difficulty swallowing or breathing, or a child who is very unwell.
Call emergency services for severe breathing difficulty, blue or grey colour, collapse, reduced responsiveness, uncontrolled bleeding or rapidly worsening serious illness.
Frequently asked questions
Should we wait and see?
Brief mild symptoms can sometimes be observed, but new, severe, persistent or worsening symptoms deserve professional advice.
What should I record?
Note timing, triggers, duration, associated symptoms, medicines, sleep and the effect on eating, drinking, movement, learning or family life.
Who should assess this?
Start with the child’s primary-care clinician, dentist, optometrist, hearing professional, maternity professional or mental-health clinician as appropriate. Emergency warning signs need urgent services.
Summary
A dental abscess needs professional treatment because pain relief alone does not remove the infection source.
