What an Abscessed Tooth Looks Like and How It’s Treated
Reviewed by Dr. Paul Rubin, DDS
Dental abscesses can develop quickly in children and often cause more than just tooth pain. Parents usually notice visible changes in the gums or face before they realize an infection is present. Knowing what an abscessed tooth looks like and when to seek care helps prevent serious complications.

What Does an Abscessed Tooth Look Like?
An abscessed tooth is a pocket of infection that forms near the root of a tooth or along the gumline.
An abscessed tooth may present with one or more of the following signs:
- A swollen or raised area on the gums near a tooth
- A small pimple-like blister that may appear white or yellow
- Redness or inflammation around the affected tooth
- Facial or jaw swelling in more advanced cases
- A tooth that looks darker or discolored compared to others
The blister may drain pus and temporarily flatten, but the infection remains active even if swelling decreases.
Common Symptoms of an Abscessed Tooth
Beyond visible changes, an abscessed tooth can cause symptoms that indicate active infection. Without treatment, these symptoms worsen over time.
Common symptoms include:
- Persistent or throbbing pain
- Sensitivity to hot, cold, or pressure
- A bad taste in the mouth or foul odor
- Fever or general signs of illness
- Swollen or tender lymph nodes in the neck or jaw
Younger patients may not always explain pain clearly. Changes such as irritability, avoiding chewing on one side, or trouble sleeping can be early signs of a problem.
How Pediatric Dentists Treat Abscessed Teeth
Treatment depends on the severity of the infection and the condition of the affected tooth. Abscesses do not resolve on their own and always require professional care.
Common treatment options include:
- Drainage of the abscess to remove trapped infection and relieve pressure
- Antibiotics to help control the spread of bacteria
- Pulpotomy (baby root canal) when the tooth can be saved
- Tooth extraction, when the tooth cannot be safely preserved or infection risk remains high
We always choose treatment with the child’s comfort, safety, and long-term dental development in mind.
When an Abscessed Tooth Is a Dental Emergency
Seek immediate medical care if your child develops:
- Fever along with tooth pain or swelling
- Visible facial swelling
- Difficulty swallowing or breathing
- Trouble opening the mouth fully
These signs suggest the infection may be spreading beyond the tooth and surrounding gum tissue.
Supporting Your Child’s Oral Health
Treating an abscessed tooth early helps relieve discomfort and prevents infection from spreading. If you notice swelling, gum changes, or ongoing tooth pain, a pediatric dentist can evaluate the area and recommend appropriate care.

FAQs
Untreated infection from a baby tooth can interfere with the development of the permanent tooth below and may affect eruption or enamel quality.
Symptoms may temporarily lessen if the abscess drains, but the infection remains and can worsen without professional care.
Most abscesses develop from untreated cavities, dental trauma, or cracks that allow bacteria to reach the tooth pulp.
Antibiotics alone do not cure the problem. Dental treatment is required to remove the source of infection and prevent recurrence.
