Knocked out an infected tooth
A knocked-out tooth with infection is an urgent dental injury; handle it gently, preserve it correctly, and seek immediate assessment.
The short answer
A knocked-out tooth that was infected still needs urgent dental assessment because the socket, surrounding bone, and nearby tissues may require treatment even if the tooth cannot be replanted. Infection does not make the injury routine.
What is the direct answer?
What does this question mean?
A tooth can be displaced by trauma, while infection may already have affected its pulp, root, or supporting tissues. A dentist must assess the tooth, socket, gum, bite, and nearby teeth, often with dental imaging, before deciding whether replantation or replacement is possible.
What can you do next?
Hold the tooth by its crown, not the root, and do not scrape or scrub it; if it is dirty, gently rinse it with milk or saline. Place it in milk or a tooth-preservation solution, control bleeding with clean gauze, and contact emergency dental care immediately.
When should you seek dental care?
Seek urgent care immediately, especially with uncontrolled bleeding, facial swelling, fever, severe pain, loss of consciousness, or a jaw injury. Do not delay because the tooth was already infected; the infection and trauma need separate assessment.
What should you ask the dentist?
Ask whether the tooth can be replanted, whether the socket needs cleaning or repair, and how the existing infection changes the plan. Ask what temporary protection and later replacement options are available if replantation is not suitable.
Frequently asked questions
Should I scrub the tooth clean?
No. Gently rinse visible debris without scraping the root surface.
What if the tooth cannot be saved?
The dentist can treat the socket and discuss a temporary and definitive replacement plan after healing is assessed.
