How Long Does Amoxicillin Take to Work for a Tooth Infection (Abscess)?

Amoxicillin can treat minor tooth infections, but it can be debilitating to wait for it to work if you have a toothache. Many people are unsure of how long it takes for the antibiotic to kick in. So, how long does amoxicillin take to work for a tooth infection? Read on to find out.

Should You Take Antibiotics for a Tooth Infection?

Before we answer the question “how long does amoxicillin take to work for a tooth infection”, it’s important to note that not all infections require antibiotics. In fact, some mild cases can be resolved with at-home remedies and good oral hygiene.

On the other hand, some tooth infections might be too severe to treat with antibiotics alone. These include abscesses or infections that have spread to other parts of the body. Your dentist will be able to determine whether you need antibiotics or a root canal.

But if you’ve already been prescribed amoxicillin, how long should you expect to wait for it to start working? Read the answer below.

How Long Does Amoxicillin Take to Work for a Tooth Infection?

On average, it takes about 2–3 days for amoxicillin to fully kick in and start working on a tooth infection. You should start feeling better within a few days, but it’s important to finish the entire course of antibiotics, even if you do. Stopping too soon can allow the infection to come back. Usually, a course will take 7–14 days to complete.

In some cases, antibiotics may not be enough to clear up a severe tooth infection. Your dentist might also recommend a root canal or other procedure.

How Long Does It Take to Stop Tooth Pain?

It’s also important to note that amoxicillin is not a pain reliever. While you wait for it to work, you can use over-the-counter pain medication and heat/cold therapy to alleviate discomfort. Without pain relief, your toothache should resolve within a few days after starting amoxicillin, but it can take up to a week for the pain to completely go away.

Will It Work Faster If You Take More?

No, increasing the dose will not make amoxicillin work faster. In fact, it can be dangerous to take more than the prescribed amount. Always follow your dentist or doctor’s recommendations and never increase the dosage without consulting them first.

Try to take your antibiotics at the same time every day to maintain consistent levels in your body and ensure they work effectively. If you miss a dose, take it as soon as possible – unless you’re close to the next one. You should never take a double dose.

How long does amoxicillin take to work for a tooth infection if you follow the recommended dosage? About 2–3 days. If you skip some doses, it could take longer for the antibiotic to start working.

Potential Side Effects of Taking Amoxicillin

Like any medication, amoxicillin can also cause side effects. These include:

  • nausea;
  • vomiting;
  • diarrhea;
  • stomach pain;
  • headache;
  • rashes;
  • changes in taste.

More severe but rare side effects can include allergic reactions, seizures, jaundice, hives, and difficulty breathing. If you experience any of these, seek medical attention immediately.

Is Amoxicillin Safe?

Despite its potential side effects, amoxicillin is generally safe for use in adults and children. However, it’s important to take it as prescribed and discuss any concerns with your dentist or doctor. Always remember to take precautions when taking antibiotics and try to prevent future tooth infections by practicing good oral hygiene.

Other Common Antibiotics Used for Dental Abscesses

How long does amoxicillin take to work for a tooth infection, compared to other antibiotics? Other medications your dentist may prescribe include penicillin, clindamycin, and metronidazole. These also tend to take 2–3 days to start working. There isn’t necessarily a “best” antibiotic for treating bacterial infections in teeth and gums – it all depends on what your dentist recommends and how your body responds.

When to Consider a Root Canal

If the pain and symptoms of your tooth infection do not improve within a few days of taking antibiotics, a root canal might be necessary. This is a procedure where the dentist removes the infected pulp inside the tooth, cleans it out, and seals it. This can prevent further infection and save your tooth from needing to be extracted.

In general, it’s essential to see a dentist as soon as possible if you suspect a tooth infection. They can accurately diagnose the issue and recommend the necessary treatment, including how long to expect for antibiotics like amoxicillin to start working.


Overall, how long does amoxicillin take to work for a tooth infection? While results vary for each individual, on average it takes about 2–3 days for the antibiotic to fully kick in and start treating the infected tooth. It’s important to finish the entire course of antibiotics, even if you start feeling better, to prevent the infection from coming back. In some cases, a root canal or other procedure might also be necessary.
