Something hurts in your mouth and you need to figure out why. Tooth pain can range from a dull ache to a sharp jolt that stops you mid-bite — and the cause isn't always obvious without knowing what to look for.
Cavities get the blame most often, but toothaches can come from cracked teeth, gum infections, grinding, sinus pressure, or even a piece of food jammed where it shouldn't be. The type of pain — sharp vs. throbbing, constant vs. triggered by hot and cold — actually tells you a lot about what's going on before you ever see a dentist.
Why Your Tooth Hurts
A toothache is your body yelling at you. Something is wrong. The specific type of pain tells you a lot about what's going on, if you know what to listen for.
Here are the six most common causes.
Cavity (dental decay). Dull, constant ache that gets worse with sweet or cold foods. The bacteria have eaten through enamel and reached the sensitive layer underneath. The deeper the cavity, the sharper the pain.
Cracked tooth. Sharp, sudden pain when you bite down on something, then it disappears. Hurts with chewing but not constantly. The crack opens under pressure, irritating the nerve, then closes again.
Abscess (infection). Throbbing, intense pain that doesn't let up. May include swelling, fever, bad taste in your mouth. This one can't wait. An abscess is a bacterial infection that can spread to your jaw, neck, or worse.
Gum disease. Sore, aching gums more than sharp tooth pain. Bleeding when you brush. Teeth may feel loose in advanced stages.
Grinding (bruxism). Generalized soreness across multiple teeth, worst in the morning. Jaw feels tired. Your teeth are taking forces they weren't designed for, eight hours a night.
Sinus infection. This is the one that fools everyone. Your upper back teeth ache, maybe several at once. It feels like a toothache, but the real problem is inflamed sinuses pressing on the tooth roots directly above them. If your "toothache" came with congestion, post-nasal drip, or facial pressure, it's probably your sinuses.
"A dental abscess requires prompt treatment. Without treatment, the infection can spread to other parts of the body." — Mayo Clinic Learn more about tooth abscess.
Symptom Decoder: What's Causing Your Pain?
| Symptom Pattern | Likely Cause | Urgency |
|---|---|---|
| Sharp pain when biting, goes away when you stop | Cracked tooth | See dentist this week |
| Constant dull ache, worse with sweets | Cavity | See dentist within a week |
| Throbbing pain that keeps you awake, swelling | Abscess/infection | Same day or emergency |
| Sensitivity to hot AND cold that lingers | Dying nerve (irreversible pulpitis) | See dentist in 1-2 days |
| Sensitivity to cold only, brief | Early cavity or recession | Mention at next checkup |
| Multiple upper teeth ache + congestion | Sinus infection | Doctor or urgent care |
| Morning soreness in several teeth, jaw fatigue | Grinding/bruxism | See dentist at next visit |
| Pain after a recent filling or crown | Normal post-procedure sensitivity | Wait 2 weeks, then call if persists |
Immediate Relief at Home
You've figured out your tooth hurts. It's 10 PM. Your dentist opens at 8 AM. Here's what to do right now.
Ibuprofen is your best friend
Take 400 to 600mg of ibuprofen (Advil, Motrin). This is better than acetaminophen (Tylenol) for dental pain, and it's not close. Here's why: most tooth pain involves inflammation. Ibuprofen is an anti-inflammatory. Acetaminophen is not. Ibuprofen attacks the pain and the swelling causing the pain.
If the pain is severe, you can alternate: 600mg ibuprofen, then 500mg acetaminophen three hours later, then ibuprofen again three hours after that. This combination is more effective than either alone and is what many oral surgeons recommend post-extraction.
Other remedies that actually help
| Remedy | How to Use It | What It Does | Effectiveness |
|---|---|---|---|
| Ibuprofen (400-600mg) | Every 6 hours with food | Reduces inflammation and pain | High |
| Saltwater rinse | 1 tsp salt in 8oz warm water, swish 30 sec | Draws out fluid, mild antiseptic | Moderate |
| Cold compress | Ice pack on cheek, 10 min on, 10 off | Reduces swelling, numbs area | Moderate |
| Clove oil | Dab on cotton ball, apply to tooth | Contains eugenol (natural anesthetic) | Moderate |
| OTC numbing gel (Orajel) | Apply directly to painful area | Topical benzocaine numbs the surface | Low-moderate (temporary) |
| Peppermint tea bag | Cooled, pressed against tooth | Mild numbing and anti-inflammatory | Low |
What NOT to Do
Don't put aspirin directly on your gum. People do this thinking it'll numb the area. It doesn't. Aspirin is acidic. It burns the gum tissue, causing a painful white chemical burn on top of your existing toothache. Swallow the aspirin normally.
Don't ignore it hoping it goes away. Tooth pain from a cavity or infection never resolves on its own. It might quiet down for a few days, but that usually means the nerve is dying, not that the problem is fixing itself. When the pain returns, it'll be worse.
Don't use heat on a swollen face. Heat increases blood flow to the area and makes swelling worse. Cold compress only.
Don't poke at it with sharp objects. If something is stuck between teeth, use floss. Not a toothpick, not a pin, not a knife. You'll push bacteria deeper.
When It's an Emergency vs. Can Wait
Go now (emergency):
- Swelling in your face, jaw, or neck
- Fever combined with tooth pain
- Difficulty breathing or swallowing
- Uncontrolled bleeding
- Trauma (knocked-out or broken tooth from injury)
- Pain so severe OTC medication doesn't touch it
Can wait for a regular appointment (1-3 days):
- Sensitivity to cold that's brief
- Mild to moderate ache controlled by ibuprofen
- Tooth that's been slightly sore for a while
- Pain only when chewing on one specific tooth
Gray zone (call your dentist's after-hours line):
- Moderate pain that wakes you up at night
- Visible crack in a tooth but no swelling
- Lost filling or crown
Utah After-Hours Options
Most Utah dental offices have an after-hours answering service that can reach the dentist for true emergencies. Call your regular office first, even at midnight, and follow the prompts.
Beyond that:
- Hospital emergency rooms can manage dental infections (antibiotics, pain control) but can't do dental procedures. Use this if you have facial swelling with fever.
- Urgent dental clinics in Salt Lake City, Provo, and Ogden offer same-day emergency appointments. Fees are higher than regular visits, typically $150 to $300 for the emergency exam.
- University of Utah dental clinics offer emergency services during business hours at reduced fees.
If the pain is controlled with ibuprofen and there's no swelling or fever, you're safe to wait until morning and call your dentist first thing.
Questions for Your Utah Dentist
- Based on my symptoms, what do you think is causing this?
- Do I need an X-ray today, or can we diagnose without one?
- Is this something that needs immediate treatment, or can we plan it?
- If it's a cavity, how deep is it? Could it need a root canal later?
- What's the cost for today's treatment, and what will my insurance cover?
- If I need to wait a few days for the full treatment, what should I do to manage pain in the meantime?
Bottom Line
Tooth pain is not something to tough out. A $200 filling now prevents a $2,000 root canal and crown later. The symptom decoder above can help you gauge urgency, and the home remedies will get you through the night. But make the call in the morning.
