What is it for?
Allowing a collection of fluid or pus to drain.

What does drainage mean for an infection in the mouth?
Drainage provides a way for collected fluid or pus to escape. A dental abscess may need treatment through the tooth, an incision into the swelling or removal of the tooth causing the infection. Treating the cause remains essential; drainage alone does not solve every problem.

Recognise a collection
An abscess is a local collection of pus. Not every swelling is an abscess, and its appearance does not reliably show how far infection has spread.
Provide an outlet
The clinician decides whether and how to drain it. Depending on the findings, drainage may be achieved through the tooth or a small opening in the affected soft tissue.
Treat the cause
Treatment of the affected tooth and follow-up may still be needed. Antibiotics are added only in particular circumstances and do not replace local treatment.

Often confused
Drainage or antibiotics?
Drainage is a local measure that allows fluid to escape. An antibiotic is a medicine and does not replace treatment of the infection source.
Quick answers
Can I lance an abscess myself?
No. Do not squeeze, pierce or insert material into a wound. A painful swelling needs dental assessment.
Does every infection need drainage and antibiotics?
No. Treatment depends on the findings. Local measures are central for a localised infection; spread or systemic symptoms may require additional treatment.
When is it urgent?
Breathing or significant swallowing problems, swelling in the floor of the mouth or rapidly spreading swelling require immediate medical help; for breathing difficulty in Germany, call 112. Fever or increasing swelling also needs urgent assessment.
At the practice
For the appointment
You can bring this question to your appointment:
How will the cause be treated, and when should the area be checked after drainage?
A painful swelling needs prompt examination; seek immediate medical help for warning signs.

Drainage is a local measure that allows fluid to escape. An antibiotic is a medicine and does not replace treatment of the infection source.
