Tooth pain is an extremely common condition that affects people of all ages. It can range from mild sensitivity to severe, debilitating pain that disrupts sleep and interferes with daily activities. When tooth pain strikes, most people reach for over-the-counter (OTC) pain medications like ibuprofen or acetaminophen to find relief. But extensive research shows that ibuprofen is actually more effective than other OTC pain relievers for treating tooth pain specifically.

In this comprehensive article, we’ll explore the reasons why ibuprofen works better than alternatives like acetaminophen when it comes to managing toothaches. We’ll look at:

  • How ibuprofen works to block tooth pain
  • The specific advantages it has over acetaminophen
  • Proper ibuprofen dosing for toothaches
  • Its risks and side effects
  • Other remedies to use alongside ibuprofen

Read on to learn why ibuprofen should be your first choice when tooth pain strikes and how to use it safely and effectively.

How Ibuprofen Works to Relieve Tooth Pain

How Ibuprofen Works to Relieve Tooth Pain

Before exploring why ibuprofen is ideal for toothaches, let’s first look at how it works to relieve tooth pain in the body.

Ibuprofen belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by inhibiting the production of prostaglandins – inflammation-fueling chemicals released in response to injury or infection.

Here are the main ways ibuprofen eases tooth pain specifically:

1. Reduces Inflammation

Most tooth pain arises from inflammation in the pulp of the tooth. The pulp contains sensitive nerves and blood vessels that become aggravated and inflamed in response to dental issues like tooth decay, cracked teeth, gum disease, or injury.

Ibuprofen helps reduce this pulsating, throbbing pain by decreasing inflammation in the pulpal tissue and halting prostaglandin production.

2. Blocks Pain Signals to the Brain

When the inner pulp tissue is inflamed, the nerves within send pain signals to the brain. Ibuprofen reduces prostaglandins that allow these pain signals from the tooth’s nerves to reach the brain. This provides pain relief right at the source.

3. Constricts Blood Vessels

Inflamed pulpal blood vessels become dilated and expanded, leading to pressure and throbbing pain. Ibuprofen helps return these blood vessels to their normal shape and size by reducing prostaglandins that trigger vasodilation and fluid buildup.

4. Has Mild Anti-Bacterial Properties

Early research indicates ibuprofen may have some anti-bacterial properties, especially against certain oral bacteria. This may contribute to its efficacy in treating tooth pain caused by dental bacterial infections. However, more studies are still needed.

5. Acts as a Pain-Blocking Analgesic

In addition to its anti-inflammatory actions, ibuprofen works directly as a strong analgesic (pain-reliever). It binds to COX enzymes and prevents pain signals from being amplified and dispersed throughout the nervous system.

Now that we’ve reviewed how ibuprofen blocks tooth pain at the source, let’s analyze why it’s the most effective OTC option compared to alternatives like acetaminophen.

Why Ibuprofen is Better than Acetaminophen for Toothaches

Why Ibuprofen is Better than Acetaminophen for Toothaches

Acetaminophen (Tylenol) is another go-to over-the-counter medication used for tooth pain relief. However, studies consistently show ibuprofen works significantly better for relieving toothaches. Here’s why:

Targets Inflammation More Effectively

While acetaminophen does have analgesic properties, it has little impact on reducing inflammation. Since inflammation is the main cause behind most sudden-onset and throbbing types of tooth pain, ibuprofen is better equipped to address this root issue, rather than just masking symptoms.

Stronger Pain-Relieving Effects

Multiple research studies directly comparing equal doses of ibuprofen (200-400mg) and acetaminophen (325-650mg) show ibuprofen provides stronger analgesic (pain-relieving) effects.

For example, one study tested pain relief in people with wisdom tooth extractions. Those given a standard 400mg dose of ibuprofen reported significantly greater pain relief than those given 1000mg of acetaminophen, even though the ibuprofen dose was lower.

Longer-Lasting Relief

On average, a single dose of ibuprofen provides toothache pain relief for 6-8 hours. In contrast, acetaminophen is effective for a shorter duration of 3-4 hours before the effects wear off. This makes ibuprofen a better choice for longer lasting coverage, especially for relief overnight while sleeping.

Less Liver Toxicity with Short-Term Use

Although generally safe at recommended OTC doses, excessive acetaminophen use over time carries a higher risk of liver toxicity compared to ibuprofen. Ibuprofen has demonstrated little to no hepatoxicity at OTC doses taken short-term. This may make ibuprofen a safer choice for recurring toothaches that require repeated pain relief.

Ideal Ibuprofen Dosage for Toothaches

When used properly, ibuprofen provides fast and effective relief from tooth pain. Here are the evidence-based dosage recommendations for ibuprofen:


  • 200-400mg every 6 to 8 hours as needed
  • Maximum daily limit of 1200mg (3 doses) for toothaches
  • Take with food to minimize stomach upset
  • Use the lowest dose that provides pain relief
  • Seek medical advice if pain lasts more than 1-2 days

  • 10mg per kg of body weight every 6-8 hours
  • Only use under medical supervision
  • Children under 2 should not take ibuprofen without doctor’s approval

In general, it’s best to take ibuprofen at the very first sign of tooth pain for preventive effects before it becomes severe. Ibuprofen works best when paired with treatment of the underlying dental issue causing pain, such as getting cavities filled.

Risks and Side Effects of Ibuprofen

Risks and Side Effects of Ibuprofen

When used as directed for short periods, ibuprofen is generally safe and well-tolerated for occasional toothaches. However, frequent overuse can increase the risks of certain side effects.

Common Side Effects

  • Nausea, upset stomach
  • Heartburn
  • Dizziness
  • Headaches
  • Rash or redness

Serious Risks

  • Kidney problems with chronic overuse
  • Increased stroke/heart attack risk at very high doses
  • Stomach ulcers and bleeding with long-term use
  • Delayed healing after dental procedures
  • Allergic reaction in sensitive individuals

To reduce side effect risks:

  • Take the lowest effective ibuprofen dose
  • Never exceed 3200mg per day
  • Use for less than 10 days for toothaches
  • Avoid in those with NSAID hypersensitivities

Also, people with hypertension, kidney disease, or bleeding disorders should use ibuprofen cautiously and ask their dentist or doctor if it’s appropriate in their situation.

Other Remedies to Use Alongside Ibuprofen

While ibuprofen should be your first go-to for fast toothache relief, also consider these home remedies to help manage pain and inflammation alongside ibuprofen:

  • Cold compresses – Ice packs or cold compresses can help numb pain. Apply for up to 20 minutes several times a day.
  • Warm Salt Water Rinses – Swishing with warm salt water helps soothe inflamed nerves and draws out fluid buildup and bacteria.
  • Dental Wax – Coat sharp points or cracks in teeth with orthodontic wax to prevent irritation.
  • Clove Oil – Applying diluted clove oil to gums has a mild numbing effect thanks to eugenol. Rinse out after 15 minutes.
  • Avoid Temperature Extremes – Prevent thermal irritation by avoiding hot and cold foods/drinks. Stick to room temperature.

Getting to the root cause of the tooth pain, such as filling cavities, performing root canals on infected pulps, or extracting problematic wisdom teeth, often provides lasting relief when combined with ibuprofen pain management.


Ibuprofen is widely regarded as the most effective over-the-counter medication for relieving toothaches, thanks to its unique capacity to reduce tooth pulp inflammation while providing strong analgesic pain relief. Multiple studies confirm it outperforms acetaminophen for fast relief of dental pain from issues like cavities, cracked teeth, erupting wisdom teeth, or pulpal infections. Just be sure to take the lowest effective ibuprofen dose for less than 10 days to avoid side effects. Combine ibuprofen with dental treatment and home remedies for optimal, lasting tooth pain relief.

Frequently Asked Questions

Q: Is it OK to use ibuprofen for a tooth infection?

A: You can take ibuprofen to temporarily relieve pain and swelling from a tooth infection until you can see a dentist. However, it won’t cure the infection itself. Make a dental appointment urgently, as untreated infections can spread.

Q: What’s better for wisdom tooth pain, ibuprofen or acetaminophen?

A: Ibuprofen is more effective for the inflammation and throbbing pain associated with erupting wisdom teeth. Its anti-inflammatory effects target this type of pain better than acetaminophen alone.

Q: How long does it take ibuprofen to work on a toothache?

A: Ibuprofen begins working within 30-60 minutes after taking a dose. However, it may take a couple doses over several hours to significantly ease severe toothache pain. Allow 6-8 hours to feel the full effects.

Q: Can I take ibuprofen before dental work?

A: Avoid ibuprofen 1-2 weeks before dental procedures where bleeding is expected. Ibuprofen can hinder clotting and increase bleeding risks. Always follow your dentist’s specific pre-op instructions.

Q: Is there a topical ibuprofen gel for toothaches?

A: Yes, topical ibuprofen gels are available over-the-counter. Applying them directly to the gums around an aching tooth provides localized relief by absorption into inflamed tissues. Oral ibuprofen works systemically as well.
