Several cases of gossypiboma have been reported after orthopedic abdominal otorhinolaryngology or plastic surgery but there has been only one reported case after oral surgery. Case presentation A 42-year-old Caucasian German-speaking Swiss woman applied to our clinic for removal of her right mandibular first molar. Her right mandibular third molar had been removed seven years ago. Post-operatively she complained of pain and foreign body sensation for six months in the area of the removed tooth. A panoramic radiograph of our patient showed a defined and oval radiolucent area in the socket of the right mandibular third molar evoking a residual cyst. An operation was planned to remove the cyst-like lesion. During surgery a foreign body composed of gauze was found in the right mandibular third molar region. The histological findings were compatible with a foreign body reaction around gauze. Conclusion Retained gauze must be considered if patients complain of pain and foreign body sensation after tooth removal. The use of gauze with radio-opaque markers and extensive irrigation of the socket with saline to remove gauze fragments can avoid this mishap.

After the third molar has been extracted and the socket has been treated the envelope sulcular mucoperiosteal flap or triangular flap is repositioned. Three wound-healing techniques following lower third molar removal exist primary closure alone primary closure with drainage and open .
