It is normal for patients to have food left in the extraction socket after wisdom tooth extraction, but they should not dispose of it by themselves. The clot is protecting the extraction socket and food will not enter the actual socket. If the patient removes the food and breaks the clot at this time, the healing of the extraction socket will be affected. Patients can brush their teeth and rinse their mouths to clean out the food retention. If there is retention and the patient is not able to clean it out, there is no need to force it too much.
