An infected tooth requires professional dental treatment to fully resolve. No home remedy, antibiotic, or pain reliever can eliminate an infection inside the tooth on its own. The good news: once treated, most dental infections heal within 10 to 15 days. Here’s what that treatment looks like, what you can do for pain in the meantime, and how to recognize when the situation is becoming dangerous.
Why Tooth Infections Don’t Heal on Their Own
A tooth infection starts when bacteria get through a cavity, crack, or chip and reach the soft tissue (called the pulp) inside the tooth. That tissue contains nerves and blood vessels, which is why it hurts so much. In the early stage, the inflammation is reversible: a dentist can repair and seal the tooth, and it recovers. But once the inflammation progresses past a certain point, the pulp tissue can no longer heal itself. It dies, and the infection spreads toward the tip of the root.
When infection reaches the root tip, it can form a pocket of pus called an abscess. That abscess won’t drain or disappear without intervention. The infection sits in a closed space that your immune system and even antibiotics have limited access to. This is why the American Dental Association recommends direct dental treatment, not antibiotics, as the first-line approach for most tooth infections.
Professional Treatment Options
Your dentist’s goal is straightforward: get rid of the infection. Which procedure they choose depends on how much of the tooth can be saved.
Draining the Abscess
If there’s visible swelling with pus buildup, the dentist may need to drain it first. This involves making a small cut into the abscess, letting the pus escape, and washing the area with saline. Sometimes a small rubber drain is placed to keep the site open while swelling goes down. The area is numbed beforehand, so you’ll feel pressure but not sharp pain during the procedure.
Root Canal
A root canal saves the tooth by removing the infected tissue inside it. The dentist drills into the tooth, clears out the dead or diseased pulp, drains any abscess, then fills and seals the empty space. Back teeth usually get a crown afterward for strength. Despite their reputation, root canals with modern anesthesia are comparable to getting a filling. The tooth is no longer alive afterward, but it stays in your jaw and functions normally.
Extraction
If the tooth is too damaged to save, pulling it is the remaining option. The dentist extracts the tooth and drains any infection. You’ll later need to discuss replacement options like an implant or bridge to prevent neighboring teeth from shifting.
When Antibiotics Are Needed
Antibiotics alone don’t cure a tooth infection, and current ADA guidelines recommend against prescribing them for most cases. They’re reserved for situations where the infection has spread beyond the tooth itself, into nearby tissues, the jaw, or other areas. Signs that antibiotics are warranted include fever, feeling generally unwell, or rapidly spreading swelling. People with weakened immune systems may also receive antibiotics as a precaution.
Managing Pain Before Your Appointment
If you can’t see a dentist immediately, you can take steps to control pain and keep the infection from worsening.
The ADA recommends combining ibuprofen and acetaminophen for dental pain. A typical dose is 400 mg of ibuprofen (two standard pills) taken alongside 500 mg of acetaminophen. This combination targets pain through two different pathways and often works better than either one alone. Alternate or repeat doses throughout the day following the instructions on each bottle, and avoid exceeding the maximum daily amount for either medication.
Rinsing with warm salt water several times a day can help draw some pus toward the surface and keep the area cleaner. Use about half a teaspoon of salt in a cup of warm water, swish gently for 30 seconds, and spit.
Clove oil is one home remedy with actual evidence behind it. The active compound acts as a natural anesthetic and has mild antibacterial and anti-inflammatory effects. A clinical trial found that clove gel applied to the gums was as effective as benzocaine (the numbing agent in over-the-counter oral gels) for pain relief. A 2024 review of 21 clinical studies confirmed it has the most consistent evidence of any plant-based dental pain treatment. You can dab a small amount onto a cotton ball and hold it against the sore area.
These measures buy you time. They cannot fix the underlying problem. If the tooth keeps hurting despite home remedies, that persistent pain signals an infection that needs professional treatment.
How Long Recovery Takes
After treatment, expect the area to feel sore and tender for a few days. Most dental abscesses heal fully within 10 to 15 days, though severe infections or surgical extractions can take longer. Swelling typically peaks in the first 48 hours and then gradually improves. Stick to soft foods on the opposite side of your mouth for the first few days, and keep up with salt water rinses to support healing.
If you had a root canal, the tooth itself may feel sensitive for a week or two as surrounding tissues calm down. If you had an extraction, the socket usually closes over within one to two weeks, with full bone healing taking several months underneath.
Warning Signs of a Spreading Infection
Most tooth infections stay localized and are treatable in a dental office. But in rare cases, the infection spreads into the neck, throat, or chest, and this can become life-threatening. One serious complication is a deep neck infection that causes rapid swelling under the jaw and tongue, which can block your airway.
Go to the emergency room if you experience any of the following:
- Difficulty breathing or swallowing
- Swelling spreading to your neck or under your jaw
- Fever or chills alongside worsening tooth pain
- A swollen or protruding tongue
- Slurred speech
- Severe pain that keeps getting worse despite medication
These symptoms can develop suddenly, sometimes within hours. Without treatment, a spreading dental infection can lead to sepsis, airway obstruction, or lung infection. This is rare, but the risk increases the longer an active infection goes untreated. Getting dental care early, even if the pain feels manageable, is the most reliable way to prevent a simple problem from becoming a dangerous one.
