Tooth extraction is a dental procedure in which a tooth is removed from its socket in the jawbone. It is usually performed when a tooth is severely damaged due to decay, infection, trauma, or overcrowding, or when wisdom teeth cause problems. The procedure is done under local anesthesia to ensure comfort, and proper aftercare helps promote healing and prevent complications. Tooth extraction relieves pain, prevents the spread of infection, and supports overall oral health when saving the tooth is not possible.
