If your tooth hurts badly right now, the most effective over-the-counter approach is combining ibuprofen and acetaminophen together. This combination outperforms either drug alone for dental pain, and the American Dental Association recommends it as the first-line treatment for acute tooth pain in adults. While that takes the edge off, you need to get to a dentist, because severe tooth pain almost always signals a problem that won’t resolve on its own.
Signs You Need the ER, Not a Dentist
Most toothaches, even terrible ones, can wait for a dental appointment within a day or two. But certain symptoms mean the infection has spread beyond your tooth and become dangerous. If swelling has moved from your gum into your face, cheek, or neck, or if you’re having any trouble breathing or swallowing, go to the emergency room. A fever alongside tooth pain also suggests a spreading infection that may need immediate treatment. The ER can manage life-threatening complications, but they typically can’t fix the underlying tooth problem, so you’ll still need a dentist afterward.
What’s Likely Causing the Pain
Severe, constant, throbbing pain usually means the soft tissue inside your tooth (the nerve and blood supply) is inflamed or infected. Dentists call this pulpitis, and there are two types that feel noticeably different.
If your pain is mostly triggered by cold drinks or sweet foods and fades within a few seconds, the inflammation is likely still reversible. The tooth can often be saved with a filling or other straightforward treatment. But if the pain lingers for more than a few seconds after the trigger is gone, if heat makes it worse, or if it hurts when you bite down, the damage to the nerve is probably permanent. That’s the type that causes the relentless, keep-you-up-at-night pain most people are searching about.
When that inflammation goes untreated, it can progress to an abscess, a pocket of infection at the root of the tooth. Abscess pain is intense and throbbing, often radiating into your jaw, neck, or ear. You might notice swollen lymph nodes under your jaw, a bad taste in your mouth, or a small bump on your gum that looks like a pimple. Sometimes an abscess ruptures on its own, flooding your mouth with salty, foul-tasting fluid and temporarily relieving the pain. That relief doesn’t mean the problem is gone. The infection is still there.
How to Manage the Pain Right Now
Ibuprofen Plus Acetaminophen
Taking ibuprofen and acetaminophen together works better than either one alone because they reduce pain through different pathways. A combination tablet contains 125 mg of ibuprofen and 250 mg of acetaminophen, with a dose of two tablets every eight hours (no more than six tablets per day) for adults and children 12 and older. If you don’t have the combination product, you can take standard doses of each separately. Ibuprofen also reduces inflammation, which is often a major part of what’s generating the pain.
Salt Water Rinse
Dissolve half a teaspoon of salt in a cup of warm water and swish it gently around the painful area. This helps draw out some fluid from swollen tissue and can flush debris from around a damaged tooth. It won’t fix anything, but it can take the intensity down a notch while you wait for medication to kick in.
Cold Compress
If you have any swelling, place an ice pack or bag of frozen vegetables wrapped in a towel against the outside of your cheek. Keep it on for 10 to 20 minutes at a time, then remove it for a break before reapplying. This constricts blood vessels in the area and reduces both swelling and pain signaling.
Numbing Gels
Over-the-counter gels containing benzocaine can temporarily numb the gum tissue around the painful tooth. They’re safe for adults and children over 2 years old when used as directed. The FDA has warned that benzocaine should never be used on infants or children under 2, because it can cause a rare but serious condition that reduces the blood’s ability to carry oxygen.
How to Get Through the Night
Toothaches famously get worse at bedtime, and there’s a straightforward reason: lying flat increases blood flow to your head, which raises pressure around the inflamed tooth and amplifies the throbbing. Prop your head up with an extra pillow or two, or sleep in a recliner if you have one. Keeping your head elevated above your heart makes a real difference in how intense the pain feels. Take your pain medication about 30 minutes before you plan to sleep so it has time to reach full effect.
What Happens at the Dentist
When you get in for an emergency dental visit, the dentist will take X-rays to see the extent of the damage and check whether infection has spread to surrounding bone. If the nerve inside your tooth is the source of the pain, the most effective way to stop it is to remove it.
During this procedure, the dentist numbs the area, drills a small opening in the tooth, and uses tiny instruments to take out the inflamed or infected tissue from inside the tooth and its roots. The tooth is then cleaned, disinfected, and sealed with a temporary filling. This is the first stage of a root canal, and for most people, the pain drops dramatically once it’s done. A second visit completes the process with a permanent filling and a crown to protect the tooth long-term.
If the tooth is too damaged to save, extraction is the other option. In cases with significant infection, the dentist may prescribe antibiotics. It’s important to finish the entire course even if the pain disappears quickly, because the infection can flare back up if bacteria aren’t fully eliminated. You can expect some soreness around the area for a few days after treatment, but it’s a different quality of pain entirely from what brought you in.
What Not to Do
Avoid putting aspirin directly on your gum. This is an old home remedy that actually burns the tissue and can make things worse. Don’t eat on the side of the painful tooth, and stay away from very hot or very cold foods and drinks if temperature seems to trigger or worsen the pain. Avoid alcohol as a pain remedy. It doesn’t work well for dental pain and can interact with pain medications you’re already taking.
Most importantly, don’t assume the pain will just go away. Tooth pain sometimes fades temporarily if the nerve dies or an abscess drains, but the infection remains active and will continue causing damage. What starts as a fixable problem can become a much more complicated and expensive one if left alone.
