A dental abscess with spreading facial swelling, difficulty swallowing, fever, or limited mouth opening requires same-day treatment. Call (503) 822-0096 immediately — these infections can become life-threatening if they spread to the airway or bloodstream. We reserve emergency slots daily and can perform incision and drainage under sedation on the same visit.

The area is anesthetized before the incision — though infected tissue can be harder to numb due to its acidity. We use nerve block techniques to anesthetize the area away from the infection, which is more effective. You may feel pressure during drainage, but sharp pain should not be present. Most patients report significant pain relief within minutes of the pus being evacuated.

Pain relief is often immediate to within hours of the procedure. The pressure that caused the throbbing pain is gone once the pus is drained. Swelling begins to decrease within 24-48 hours. Full resolution of the infection, with antibiotic support, typically takes 5-10 days.

Antibiotics cannot penetrate the abscess wall effectively. The pus inside the cavity is essentially cut off from blood circulation. Antibiotics kill bacteria in the surrounding tissue but cannot sterilize the abscess itself. Without drainage, the infection persists, worsens, or temporarily improves only to recur when antibiotics are stopped.

After local anesthesia (and IV sedation if needed), the surgeon makes a small incision in the swelling to release trapped pus. A Penrose drain — a small rubber strip — is placed to keep the incision open so remaining infection drains over 2-3 days. You receive antibiotics and pain medication. A follow-up visit in 2-3 days removes the drain and evaluates healing.

In most cases, yes — the source of the infection (the tooth) must be addressed to prevent recurrence. Sometimes the tooth is extracted at the same visit as the I&D. Other times, we drain the abscess first, prescribe antibiotics to reduce the acute infection, and extract the tooth a few days later when conditions are more favorable.

If the tooth is restorable and root canal therapy is a viable option, I&D provides temporary control of the infection while the root canal is planned. The drain is removed in a few days, and root canal therapy is performed within 1-2 weeks to permanently address the source. Without treating the tooth, the abscess will recur.

I&D is typically coded as a surgical procedure and is covered by most dental insurance plans. The fee depends on the complexity and location of the abscess. Additional costs may include antibiotics, follow-up visits, and definitive treatment of the source tooth (extraction or root canal). We provide cost details at the time of treatment.

Amoxicillin (or amoxicillin with clavulanate for resistant infections) is the standard first-line antibiotic. Clindamycin is prescribed for penicillin-allergic patients. Metronidazole may be added for deep or mixed anaerobic infections. The antibiotic course typically lasts 7-10 days following I&D.

Yes, if the source tooth is not treated. I&D manages the acute infection but does not cure the underlying cause. The tooth that caused the abscess must be extracted or have root canal therapy performed. Without source control, the abscess will re-form — often within weeks to months.

Palatal abscesses are incised directly through the palatal tissue. The palatal mucosa is thick and tightly bound to bone, so swelling is less obvious but pressure and pain can be intense. Drainage provides dramatic relief. The dense palatal tissue often does not require a drain — the incision is left open for a few days to allow continued drainage.

Go to the ER if you have difficulty breathing or swallowing, swelling involving the neck or floor of the mouth, high fever with inability to keep fluids down, swelling that is closing your eye, or feeling very unwell (faint, confused, or with rapid heartbeat). These signs suggest a spreading infection requiring IV antibiotics and possibly hospital-based surgical management.

Most I&D procedures are performed under local anesthesia alone because they are quick (15-20 minutes). IV sedation is available if the patient is extremely anxious or if the I&D is being combined with extraction. The need for fasting before sedation must be balanced against the urgency of treating the infection.

Pus is composed of dead white blood cells (neutrophils), bacteria, necrotic tissue, and inflammatory fluid. Its yellow-green color and foul odor come from enzymes released by dying neutrophils and the metabolic byproducts of anaerobic bacteria. The presence of pus confirms active bacterial infection and the need for surgical drainage.

Usually yes. The abscess originated from a dead or severely infected tooth. Drainage treats the acute infection, but the source tooth needs definitive treatment — either root canal therapy (if the tooth is restorable) or extraction. We evaluate the tooth after the infection resolves and recommend the best long-term solution, which may include implant replacement.
