How to Handle a Dental Emergency: What to Do Before You See a Dentist
It seems that your dental emergency always strikes at the worst possible time: right before the weekend, on vacation, or in the middle of the night. Knowing what to do in the first few minutes can make the difference between saving or losing a tooth, preventing infection, and avoiding long-term damage.
Here’s a clear guide on what to do for the most common dental emergencies.
1. Tooth Falls Out (Knocked-Out Tooth)
If a permanent tooth gets knocked out, time is everything. You have about 30 to 60 minutes to try to save it.
What to do immediately:
- Handle the tooth only by the crown (the white part you normally see in your mouth). Avoid touching the root.
- Rinse gently with saline or milk if dirty — do not scrub or remove any tissue attached.
- Reinsert the tooth back into its socket if possible, holding it in place by gently biting on gauze.
- If reinsertion isn’t possible, store the tooth in milk, saline, or inside your cheek to keep it moist.
- See a dentist immediately. The sooner it’s reimplanted, the better the chance of saving it.
For baby teeth, do not reinsert them — it can damage the developing adult tooth beneath. Still, see a dentist to ensure no pieces remain and the surrounding tissue is healthy.
2. Severe Toothache
A toothache is usually the most miserable dental emergency. It’s your body’s way of saying something is wrong — whether it’s decay, infection, or nerve inflammation.
What to do:
- Rinse with warm salt water (½ teaspoon salt per 8 oz of water) to soothe the area.
- Floss gently around the sore tooth to remove trapped food.
- Alternate taking ibuprofen and tylenol every 4-6 hours as needed to manage pain.
- Apply a cold compress to the outside of your cheek to reduce swelling.
- Avoid placing aspirin directly on the gum — it can cause burns.
If pain keeps you up at night or throbs with your heartbeat, it could signal an infection or abscess that needs professional care immediately. You can learn more about toothaches here!
3. Chipped or Broken Front Tooth
This dental emergency could be anything from a minor cosmetic issue to a serious structural fracture. This post does a great job highlighting everything to consider.
If the tooth only chipped slightly:
- Rinse your mouth to clear debris.
- If sharp edges are irritating your tongue or lips, cover them with dental wax, sugarless gum, or orthodontic wax.
- See a dentist soon for cosmetic bonding or smoothing.
If the tooth broke deeply or is painful:
- Avoid chewing on that side.
- If the pulp (nerve) is exposed, you may see pink tissue or bleeding — this requires immediate dental attention.
- Bring any broken pieces with you; sometimes they can be bonded back.
A quick repair not only restores your smile but also prevents infection or nerve exposure.
4. Dental Abscess (Swelling or Pus)
A dental abscess is a serious dental emergency, an infection under the tooth or in the gums, and it can spread quickly.
Symptoms:
- Throbbing pain
- Swelling of the face or jaw
- A pimple-like bump on the gum
- Fever or bad taste in the mouth
What to do:
- Rinse with warm salt water several times a day to help draw out fluid.
- Take pain relievers for comfort.
- Do not attempt to pop the abscess — this can spread infection.
- If you experience facial swelling, fever, or difficulty breathing/swallowing, go to the emergency room immediately.
Antibiotics and drainage by a dentist are often needed, followed by root canal therapy or extraction to remove the source of infection.
5. Crown Fell Off
Crowns can loosen due to old cement, decay, or sticky foods.
If your crown falls off:
- Check if you can fit it back on your tooth. Clean the inside with toothpaste or mouthwash.
- Use temporary dental cement (available at most pharmacies) or even toothpaste to hold it in place until you can see your dentist.
- If the tooth is sensitive, cover it with dental wax or sugarless gum.
- Avoid chewing on that side.
While it may not be quite as serious of a dental emergency, you’ll want to get it recemented before your teeth shift, causing it to no longer fit properly. Bring the crown with you — your dentist may be able to recement it if the tooth structure underneath is healthy.
6. Cold-Sensitive Tooth
If your tooth zings with cold air, ice cream, or water, it may be due to gum recession, worn enamel, or a small cavity.
What to do:
- Use a sensitivity toothpaste (like Sensodyne) twice daily.
- Avoid whitening products and acidic foods (soda, citrus, vinegar).
- Brush gently with a soft-bristled brush.
- If sensitivity worsens or is localized to one tooth, schedule an exam — there may be decay or a cracked tooth that needs treatment.
Mild, occasional cold sensitivity isn’t an emergency — but a sudden increase in intensity could be an early warning sign.
7. Heat-Sensitive Tooth
Sensitivity to heat, especially if it lingers, often points to nerve inflammation or infection deep inside the tooth. This is different from cold sensitivity and usually more serious.
What to do:
- Avoid hot foods or drinks to prevent aggravating the nerve.
- Take ibuprofen for inflammation.
- Call your dentist promptly — heat sensitivity that lasts after the stimulus is removed can mean the nerve is dying or infected.
- A root canal or other treatment may be necessary to save the tooth.
Ignoring heat sensitivity can allow infection to spread to the bone or cause severe pain later.
8. Pain When Biting or Chewing
Pain during biting usually signals a cracked tooth, high filling, or infection.
Steps to take:
- Avoid chewing hard foods (nuts, ice, crusty bread).
- Note whether pain happens on release (cracked tooth) or only during pressure (high filling).
- Use over-the-counter pain relief as needed.
- Schedule a dental evaluation quickly — cracked teeth can worsen fast and sometimes require crowns or root canal therapy.
A quick diagnosis prevents the crack from spreading deeper into the root where it can’t be repaired.
When to Go to the Dentist Immediately
Go to an emergency dentist or ER right away for your dental emergency if you experience:
- Severe swelling or pain preventing you from eating, speaking, or sleeping
- Facial swelling extending toward the eye or throat
- Uncontrolled bleeding
- A knocked-out permanent tooth
- Signs of spreading infection (fever, chills, fatigue)
Even if your symptoms feel minor, it’s always better to get checked than to risk long-term damage.
Preventing Any Future Dental Emergency
Many emergencies can be prevented with consistent care and a few simple habits:
- Wear a mouthguard during sports or nighttime grinding.
- Avoid chewing ice, hard candies, or using teeth as tools.
- Keep regular checkups every six months to catch small problems before they turn urgent.
- Maintain good brushing and flossing habits to reduce infection risk.
- Get crowns, fillings, or sensitivity issues addressed promptly.
Final Thoughts
Dental emergencies can be stressful, but quick, calm action makes all the difference. Knowing how to protect, clean, and store damaged teeth — and when to call your dentist — can save your smile and prevent costly complications.
If you’re unsure whether it’s an emergency, err on the side of caution and call your dentist. Most offices have after-hours lines or weekend emergency availability. Acting fast can mean the difference between saving and losing a tooth.
