Buccal space infection; a most common yet diverse case that is frequently reported to clinics. Especially rural parts of Nepal and India where dental treatment is quite neglected, buccal space infection is frequently seen . This might be difficult to manage if the condition is worse.

On palpation:

  • The buccal vestibule adjacent to the lower left 1st molar was very painful but no swelling and pus collection was observed. (This rule out vestibular abscess or space infection)

Hard Tissue Examinations:

  1. Caries: 16,37,46,48
  2. Root stump:17, 36
  3. Peripapical abscess: 36,37,46,47
  • The tooth of concern as per OPG and clinical findings is to be 36 and 37. 
  • There is bone loss observed with periapical radiolucency . So the Cause of this infection is Periapical Origin as a result of pulpal necrosis of 36 and 37.

Treatment plan of buccal space infection:


Since the swelling has started since 2 days and there is no collection of pus, no fluctuating swelling on palpation and no signs of sinus or fistula , it can be managed by medication followed by extraction of tooth resulting in odontogenic infections. However if the condidtion had been severe the management of space infection would be additional and more specific.
