A tooth infection needs professional dental treatment to fully resolve. No home remedy or antibiotic alone will cure it. But there’s plenty you can do right now to manage pain, prevent the infection from spreading, and get the right care as quickly as possible.
Manage Pain While You Wait for Treatment
The most effective over-the-counter approach for dental pain is combining ibuprofen and acetaminophen. A combination tablet (250 mg acetaminophen and 125 mg ibuprofen) can be taken as two tablets every eight hours, up to six tablets per day. If you don’t have a combination product, you can alternate standard doses of each. This pairing works better than either one alone because they reduce pain through different pathways. Ibuprofen also helps with the swelling that’s contributing to pressure and throbbing around the infected tooth.
A saltwater rinse helps keep the area clean and can draw some fluid out of swollen tissue. Mix one teaspoon of salt into eight ounces of warm water and swish gently. If your mouth is too sore, cut the salt to half a teaspoon for the first day or two. You can rinse several times a day, especially after eating.
Clove oil has a mild numbing and antiseptic effect and can temporarily ease a toothache. Apply a small amount to a cotton ball and dab it directly on the tooth. Be careful to avoid your gums, though. Repeated contact with soft tissue can cause blistering, swelling, and gum damage. It’s a short-term measure, not something to use for days on end.
Why You Still Need a Dentist
A tooth infection starts when bacteria reach the inner pulp of a tooth, usually through deep decay, a crack, or an old filling that’s broken down. Once the pulp is infected, the body walls off the bacteria with pus, forming an abscess. That abscess won’t drain or heal on its own. Even if pain fades temporarily, the infection is still there, and it will come back, often worse.
Antibiotics can control the spread of infection, but they can’t reach the source inside the tooth. The American Dental Association recommends antibiotics only when the infection has moved beyond the tooth itself and you’re showing signs like fever, malaise, or facial swelling. For a localized toothache without those signs, antibiotics aren’t indicated. The definitive treatment is always a dental procedure that removes the infected tissue.
What Treatment Looks Like
Your dentist will typically choose between two procedures: a root canal or an extraction. A root canal removes the infected pulp from inside the tooth, cleans and seals the canals, and preserves your natural tooth. You’ll usually need a crown afterward to protect the remaining structure. An extraction removes the entire tooth.
Root canals are the preferred option when the tooth still has enough healthy structure to save. They’re generally less expensive in the long run because replacing a missing tooth with a bridge or implant costs more than keeping the original. Without insurance, a root canal averages around $1,200, ranging from about $776 for a front tooth up to $2,471 for a molar. A crown adds another $800 to $2,500 depending on the material. Extraction is simpler upfront but leaves a gap that can cause neighboring teeth to shift, making future dental work more complex.
If there’s an active abscess, your dentist may drain it before or during the procedure. This provides fast relief from the pressure that’s causing much of your pain. After treatment, temporary sensitivity is common, but most people feel back to normal within a few days.
When Antibiotics Are Prescribed
If your infection has spread enough to cause fever, swelling beyond the immediate tooth area, or general feelings of illness, your dentist will prescribe antibiotics alongside the dental procedure. The standard first choice is amoxicillin, taken three times daily for three to seven days. If you’re allergic to penicillin, alternatives include azithromycin or clindamycin.
Your dentist should check in within three days of starting the prescription, either by phone or in person, to make sure the infection is responding. One important detail: current ADA guidelines recommend stopping antibiotics 24 hours after your symptoms resolve, even if that’s before you’ve finished the full bottle. If the first antibiotic isn’t working after a few days, your dentist may switch to a broader-spectrum option or add a second antibiotic.
Signs You Need Emergency Care
Most tooth infections can wait a day or two for a dental appointment. Some cannot. Facial swelling that spreads from a dental abscess into deeper tissue is a genuine emergency called facial cellulitis, and it can become life-threatening quickly. Get to an emergency room if you notice any of the following:
- Swelling near your eye or down your neck. This suggests the infection has moved into deep tissue spaces.
- Difficulty breathing or swallowing. A swollen tongue, drooling, or slurred speech can signal a condition called Ludwig’s angina, which starts from an infected lower molar in over 90% of cases. It can block your airway.
- Fever with chills and a rapid heartbeat. These are signs of sepsis, meaning the infection has entered your bloodstream.
- Trouble opening your mouth. Severe jaw stiffness (trismus) indicates deep tissue involvement.
These complications are rare but serious. Ludwig’s angina, if untreated, can lead to airway obstruction, pneumonia, or septic shock. In the ER, treatment typically involves IV antibiotics, imaging to map the infection’s spread, and surgical drainage. The infected tooth will still need to be treated afterward to prevent recurrence.
What Not to Do
Don’t place aspirin directly on your gums. This old home remedy causes chemical burns to soft tissue. Don’t ignore a tooth infection because the pain stopped. Abscesses sometimes rupture on their own, which relieves pressure and pain but doesn’t eliminate the infection. The bacteria are still active, and the abscess will reform or spread. Don’t rely on multiple rounds of antibiotics without getting the tooth treated. Each course of unnecessary antibiotics increases the risk of resistant bacteria and delays the procedure that actually fixes the problem.
If cost is a barrier, dental schools offer supervised treatment at significantly reduced prices. Community health centers with sliding-scale fees are another option. Some dentists offer payment plans for root canals and extractions. Waiting rarely makes a tooth infection cheaper to treat, because the longer you wait, the fewer options your dentist has to save the tooth.
