An abscess is a pocket of infection at the root of a tooth or in the gum beside it. It does not drain on its own and it does not improve with time.
Signs that mean call today
Swelling that comes and goes is still an abscess. When the bump drains, pressure drops and pain eases, but the infection is still there.
- Swelling in your cheek, jaw or under your eye, even if it is not painful
- Throbbing pain that wakes you or keeps you awake
- A pimple-like bump on the gum, sometimes with a salty or bad taste
- A tooth that is suddenly very sensitive to pressure or hot
- Fever, or feeling generally unwell with any of the above
Signs that mean go to the ER first
These can become dangerous within hours. Go to the emergency room, then call us for follow-up once you are stable. Antibiotics from the ER buy time; the tooth still needs treatment.
- Swelling spreading toward your eye or down your neck
- Difficulty swallowing or breathing
- Fever with facial swelling that is getting worse quickly
- You cannot open your mouth
What we do at the visit
An exam and an X-ray to find the source. If it is the tooth, we drain the infection and protect the tooth, then coordinate with a trusted specialist when nerve treatment is needed, or remove the tooth if it cannot be saved. If it is a gum abscess, a deep cleaning of that area usually resolves it. You hear the options and cost before anything starts.
Most emergency exams and X-rays are covered by PPO plans. We hold same-day time on weekdays.
What to do while you wait
Rinse with warm salt water. Take ibuprofen or acetaminophen as directed. A cold compress on the outside of the cheek helps swelling. Do not apply heat, and do not try to pop a gum bump yourself.
