Postextraction Problems

Swelling is normal after oral surgery and is proportional to the degree of manipulation and trauma. An ice pack (or a plastic bag of frozen peas or corn, which adapts to facial contours) should be used for the first day. Cold is applied for 25-minute periods every hour or 2. If swelling persists or increases after 3 days, or if the pain becomes severe, then the patient should be referred back to their dentist or surgeon (1).

Postoperative pain varies from moderate to severe and is treated with analgesics (see Treatment of Pain).

Postextraction bleeding usually occurs in the small vessels. Any clots extending out of the socket are removed with gauze, and a 4-inch gauze pad (folded) or a tea bag (which contains tannic acid) is placed over the socket. Then the patient is instructed to apply continuous pressure by biting for 1 hour. The procedure may have to be repeated 2 or 3 times. Patients are told to wait at least 1 hour before checking the site so as not to disrupt clot formation. They also are informed that a few drops of blood diluted in a mouth full of saliva appear to be more blood than is actually present.

2). In those who are at increased risk of bleeding due to comorbid disease or in those undergoing more extensive procedures, consulting with their patient's physician about timing of antiplatelet or anticoagulant dosing or a brief 24- to 48-hour interruption in therapy is indicated.

Postextraction alveolitis is pain emanating from bare bone if the socket’s clot lyses. Although this condition is self-limited, it is quite painful and usually requires some type of intervention. It is much more common among people who smoke or use oral contraceptives and occurs mainly after removal of mandibular molars, usually wisdom teeth. Typically, the pain begins on the second or third postoperative day, is referred to the ear, and lasts from a few days to many weeks.

3). The gauze is changed every 1 to 3 days until symptoms do not return after the gauze is left out for a few hours. More recently, a commercially available mixture of butamben (an anesthetic), eugenol, and iodoform (antimicrobial) has become more commonly used. Although not resorbable, this mixture washes out of the socket spontaneously after a few days. These procedures typically eliminate the need for systemic analgesics, although nonsteroidal anti-inflammatory drugs (NSAIDs) may be given if additional pain relief is needed. Patients should follow up with a dentist in 24 hours.

Osteomyelitis, which in rare cases is confused with alveolitis, is differentiated by fever, local tenderness, and swelling. If symptoms last a month, a sequestrum (ie, localized area of necrotic bone), which is diagnostic of osteomyelitis, should be sought by dedicated dental radiograph or CT scan. Osteomyelitis requires long-term treatment with antibiotics effective against both gram-positive and gram-negative organisms and referral to an oral surgeon for monitoring and/or definitive care.

Osteonecrosis of the jaw is an oral lesion involving persistent exposure of mandibular or maxillary bone, which usually manifests with pain, loosening of teeth, and purulent discharge. ONJ may occur after dental extraction but also may develop after trauma or radiation therapy to the head and neck.

Medication-related ONJ

Management of osteonecrosis of the jaw is challenging and typically involves palliation, limited debridement, antibiotics, and oral rinses.
