Blister in tooth extraction site
A bump after extraction may be healing tissue, trapped food, or infection, and its timing and symptoms determine whether it needs review.
The short answer
A bump after extraction may be healing tissue, trapped food, or infection, and its timing and symptoms determine whether it needs review. Do not pop, squeeze, or scrape it because that can injure the clot and healing socket.
How does an extraction socket normally heal?
The extraction socket contains a blood clot that is gradually replaced by healing tissue and bone. A pale or reddish raised area can be part of healing, while a fluid-filled swelling, worsening pain, bad taste, pus, or fever can point to infection or another complication.
What can you do to protect the extraction site?
Follow the extraction instructions, keep food away with gentle rinsing when permitted, and brush the other teeth carefully. Avoid probing the socket, smoking, and forceful spitting, and contact the treating clinic if the bump changes or pain increases.
When does a bump after extraction need review?
Seek dental review for increasing pain after initial improvement, facial swelling, pus, fever, persistent bleeding, a foul taste, or difficulty opening the mouth. Breathing or swallowing difficulty requires urgent medical attention.
What should the dentist identify at the extraction site?
Ask whether the appearance matches normal socket healing, an exposed bone fragment, food retention, or infection. Ask whether the socket needs irrigation, medication, removal of a fragment, or another examination.
Frequently asked questions
Is white tissue in the socket always pus?
No. Pale healing tissue can look white, but discharge with worsening pain, bad taste, or swelling needs assessment.
Can I rinse the blister away?
Do not use forceful rinsing or probing; follow the extraction instructions and ask the clinic about gentle rinsing.
