What to do right now
1. Call us immediately — same-day treatment for dental abscesses before 3pm.
2. ER if you have spreading facial swelling, difficulty breathing/swallowing, or high fever.
3. Ibuprofen 400-600mg + acetaminophen 500-1000mg combo every 6 hours.
4. Cold compress (NOT heat) on outside of cheek — 20 min on, 20 off.
5. Warm salt-water rinse 3-4 times daily if draining.
6. DO NOT apply aspirin to gum — chemical burns.
7. DO NOT try to lance or squeeze the abscess yourself.
A tooth abscess is a serious bacterial infection that won’t resolve on its own. Call us at 480-331-4955 — we treat dental abscesses same-day at our Gilbert practice when we can. An abscess is the body trying to wall off an infection that’s reached the pulp of a tooth or the surrounding bone. Without treatment, it can spread to the jaw, into the bloodstream, or up into the face — and in rare cases that progression becomes life-threatening within days. The good news: treated early, a dental abscess is straightforward to resolve.
What an abscess feels like — and when it’s an emergency vs urgent
- Emergency — come in today, regardless of hour. Swelling that’s spreading visibly to the cheek, jaw, or neck. Difficulty swallowing, opening your mouth, or breathing. Fever above 101°F (38.3°C). Rapidly worsening pain. Visible pus draining from the gum. Bad taste suddenly worsened. Chills. Any of these signs warrant calling us immediately, and if you can’t reach us, going to an emergency room. Spreading dental infections cause a small number of hospitalizations and rare deaths in the U.S. every year — the difference between a routine dental visit and a critical emergency is sometimes 24-48 hours of progression.
- Urgent — call today, see us within 24 hours. Localized throbbing pain in one tooth, increasing over a day or two. Tenderness when biting on the affected tooth. Visible pus pocket on the gum but no spreading swelling. Bad taste in the mouth. Mild localized swelling. Sensitivity to hot. These warrant treatment promptly to prevent progression but don’t require an emergency room.
- Watch — call within 48 hours. Mild discomfort suggesting infection might be developing, but no pus, no swelling, no fever. We’ll see you on the next available appointment, often within 1-2 days.
The two main kinds of abscess
- Periapical abscess. Infection at the tip of the root, almost always from decay that reached the pulp or from a cracked tooth that let bacteria in. The pulp dies, the infection spreads through the root canal into the bone at the tip. This is by far the most common kind. Treated with root canal therapy or extraction.
- Periodontal abscess. Infection in a gum pocket alongside an otherwise healthy tooth, usually from advanced gum disease or a foreign body (popcorn hull, food fragment) lodged in a deep pocket. Treated with deep cleaning of the pocket and antibiotics.
- Pericoronitis. Specifically affects partially-erupted wisdom teeth where the gum flap traps food and bacteria. Treated with cleaning, antibiotics, and often eventual extraction of the wisdom tooth.
What to do right now while you’re trying to reach us
- Take ibuprofen if you can take it. 600mg every 6 hours, with food, helps reduce inflammation as well as pain. (Skip if you have a contraindication: kidney disease, certain blood thinners, severe asthma, or you’re pregnant in the third trimester.)
- Acetaminophen alongside ibuprofen for stronger pain relief. 1000mg of acetaminophen plus 600mg of ibuprofen, alternating every 3 hours, outperforms most opioids for dental pain in published trials. Don’t exceed 3000mg of acetaminophen in 24 hours.
- Cool compress on the outside of the cheek. 15-20 minutes on / 15 off. Reduces swelling and dulls pain. Avoid heat — it draws more blood to the area and can spread infection faster.
- Salt-water rinse. 1/2 teaspoon of salt in 8 ounces of warm (not hot) water, swished gently around the affected area for 30 seconds. Repeat every few hours. Helps draw fluid out of the swollen tissues and provides mild antibacterial effect.
- Don’t pop or squeeze a visible pus pocket. If pus is draining on its own, that’s ok — rinse with salt water and let it. But don’t actively squeeze or break it — you can spread the infection further into surrounding tissues.
- Don’t apply aspirin directly to the gum. A common but harmful folk remedy — aspirin is acidic and burns gum tissue. Take aspirin orally if you take aspirin; don’t put it on the tooth.
- Hydrate, especially if you have fever. Plain water or oral rehydration solution. Skip alcohol, sugary drinks, and acidic juices.
- Sleep with your head elevated. Reduces overnight throbbing.
What we do at the emergency visit
- Diagnosis. Visual exam, percussion test (gentle tap to identify the painful tooth), thermal test, X-ray. Sometimes the tooth that hurts isn’t the one infected — we make sure we’ve identified the right tooth before treating.
- Drain the abscess. The most important first step. With local anesthesia, we either: (a) open the tooth into the pulp chamber to drain through the canal, or (b) make a small incision in a gum-pocket abscess to drain the pus. Drainage relieves the pressure and starts the healing process — pain often improves within hours.
- Antibiotics if indicated. Most localized abscesses with adequate drainage don’t need antibiotics — the drainage IS the treatment. Antibiotics are added when there’s spreading infection, fever, immune compromise, or when drainage isn’t complete. Common choices: amoxicillin, or clindamycin if penicillin-allergic. We don’t over-prescribe; the data on routine antibiotics for dental abscesses doesn’t support reflexive use.
- Definitive treatment plan. The drainage is symptom relief, not a cure. The tooth needs definitive treatment — usually root canal therapy (preserves the tooth) or extraction (removes the source of infection). Periodontal abscesses get periodontal therapy. We schedule the definitive procedure within 1-2 weeks while the immediate pain is being managed.
- Pain management for home. Ibuprofen + acetaminophen as primary pain control. Opioids only when ibuprofen is contraindicated or pain is severe and short-lived.
- Follow-up. Within 24-48 hours by phone or visit to confirm symptoms are improving. If they’re worsening, antibiotics may be added or escalation to oral surgery considered.
Definitive treatment options
- Root canal therapy. Preserves the natural tooth. The infected pulp is removed, the canals are disinfected, and the tooth is sealed. Most root-canal-treated teeth last decades. Followed by a crown 2-4 weeks later. $700-$1,700 (root canal) + $1,200-$1,900 (crown). See our root canal page.
- Extraction. Removes the tooth and the source of infection in a single procedure. Faster timeline (one visit), lower upfront cost, but creates a gap that needs to be replaced for long-term function. $200-$950 depending on tooth complexity.
- Replacement after extraction. Implant ($4,500-$6,500), bridge ($2,800-$4,800), or partial denture ($1,200-$2,800). The right choice depends on the tooth’s location and the patient’s overall plan. Implants typically planned 3-6 months after the extraction once the bone heals.
What happens if you wait
- Days 1-3 untreated. Pain typically increases. Antibiotics from a doctor or urgent care may temporarily reduce symptoms but don’t address the source — the infection often returns or progresses once antibiotics finish.
- Days 3-10 untreated. The infection may “burst” through the gum, creating a draining sinus tract (a small pimple-like opening that releases pus). Pain often improves at this point because pressure is relieved — but the infection is still active and doing ongoing bone damage.
- Weeks-to-months untreated. Chronic infection erodes the bone around the root, often eventually destroying enough bone that the tooth becomes loose or non-restorable. What started as a treatable abscess becomes an extraction. Adjacent teeth can also be affected if the infection spreads to their root tips.
- Acute spreading infection (rare but serious). Sudden worsening — spreading swelling into the face or neck, difficulty swallowing or breathing — can require hospital admission, IV antibiotics, surgical drainage, and rarely is life-threatening (Ludwig’s angina, sepsis from oral infection). Old data on dental-infection-related deaths in the U.S. shows these are uncommon but real.
Costs
- Emergency exam + X-ray: $130-$280.
- Drainage of abscess: $150-$400.
- Antibiotic prescription: $10-$30 at most pharmacies for amoxicillin or clindamycin.
- Definitive treatment: root canal + crown ($1,900-$3,600 total) or extraction ($200-$950).
- Replacement after extraction: implant ($4,500-$6,500), bridge ($2,800-$4,800), partial denture ($1,200-$2,800).
Emergency dental visits are covered by dental insurance like any other procedure. Some emergencies that involve hospitalization or facial trauma may also have medical insurance coverage. We file directly. We’re in-network with Delta, Cigna, Aetna, BCBS AZ, and AHCCCS. CareCredit and in-house financing are available for the rest.
Prevention
- Address decay before it reaches the pulp. Most periapical abscesses start as untreated decay. Six-month checkups catch decay while it’s still a small filling, not a future root canal.
- Don’t ignore lingering tooth sensitivity. Cold sensitivity that lasts more than a few seconds, or sensitivity to sweet that’s new, often signals reversible inflammation that’s on its way to becoming an abscess. Treated early, it’s a filling. Treated late, it’s a root canal.
- Treat gum disease. Periodontal abscesses arise from advanced periodontal pockets. Treating gum disease prevents the pockets from getting deep enough to abscess.
- Take cracked teeth seriously. A crack that lets bacteria into the pulp space is the second most common cause of dental abscesses. Crowns or onlays seal cracks; ignoring them lets infection develop.
If you suspect a dental abscess, call 480-331-4955 now. Don’t wait to “see if it gets better” — in dental infection, the early visit is the cheap one.
