What To Do About Tooth Pain or a Dental Injury When You Can’t See a Dentist
Rinse your mouth with warm water, control any bleeding with clean gauze, and use an over-the-counter pain reliever if you’re able to take one. Save any broken or knocked-out tooth pieces, and get to a dentist as soon as one becomes available. These steps buy time. They do not treat the underlying problem, and a dentist should still examine the tooth when you can reach one.
This article covers common dental emergencies people run into during power outages, travel, remote living, or any stretch of time without access to a dentist. It is educational information, not medical or dental advice, and it does not replace a professional exam.
Warning Signs That Need Emergency Medical Care, Not Just a Dentist
Most dental problems are painful but not life-threatening. A few situations are different. Seek emergency medical care right away if you notice any of these:
- Swelling that spreads to the eye, neck, or under the jaw, or that makes it hard to swallow or breathe
- A fever along with facial swelling
- You cannot close your upper and lower teeth together after an injury, which can mean a broken jaw
- Heavy bleeding from the mouth that does not slow down with steady pressure
- A head or facial injury severe enough to cause confusion, vomiting, or loss of consciousness
These signs mean the problem has moved beyond the tooth itself. A tooth infection that spreads into the jaw, neck, or bloodstream can become dangerous, so don’t wait on these symptoms.
Toothache: What’s Normal and What Needs Attention
A toothache is usually caused by tooth decay, an infection, or an injury to the tooth. Sometimes pain that feels like it’s coming from a tooth is actually referred from somewhere else, like an earache.
If you can’t reach a dentist right away, an over-the-counter pain reliever can help manage discomfort. Contact a dentist or health care provider as soon as you can if any of the following apply:
- The toothache is severe
- Pain lasts longer than a day or two
- You have a fever along with the toothache
- You have pain when opening your mouth wide
Broken or Chipped Tooth
Rinse your mouth with warm water to clean the area. If there’s swelling, hold a cold compress against the outside of your face near the injured tooth. A minor chip that isn’t causing pain may not need an emergency visit, but you should still have a dentist look at it eventually. Sharp edges from a broken tooth can cut the inside of your cheek, lip, or tongue, so it’s worth protecting the area with dental wax or a clean piece of gauze if the edge is bothering you.
Knocked-Out (Avulsed) Tooth
A knocked-out permanent tooth is one of the few dental injuries where minutes matter. The longer a tooth is out of the mouth, the lower the chance a dentist can save it. Here’s what to do:
- Find the tooth and pick it up by the crown (the white chewing surface), never by the root
- If the tooth is dirty, rinse it gently with water. Do not scrub it, use soap, or remove any tissue still attached to it
- If you’re able to, gently place the tooth back into its socket, facing the right way, and have the person bite down softly on gauze to hold it in place
- If you can’t put it back in place, keep it moist. Store it in a container with milk, or hold it between the lower lip and gum or under the tongue. Do not let it dry out, and do not wrap it in a tissue or cloth
- Apply a cold compress to the outside of the face to reduce swelling, and use gauze with gentle pressure to control any bleeding
- Get to a dentist immediately
Baby teeth are generally not put back in place, so this urgency mostly applies to permanent adult teeth. After a tooth is replanted, a root canal is often needed later to remove the damaged nerve tissue, which is one more reason to follow up with a dentist even after the tooth feels stable.
Tooth Abscess and Signs of Infection
A tooth abscess is a pocket of pus caused by a bacterial infection in or around a tooth. It can develop from untreated decay or from a tooth that’s been broken, chipped, or otherwise injured. The main symptom is a severe, continuous toothache that can feel gnawing, sharp, or throbbing. Other signs include:
- A bitter taste in the mouth or noticeable bad breath
- Fever or general ill feeling
- Pain when chewing, or sensitivity to hot and cold
- Swelling of the gum near the tooth, sometimes looking like a small pimple
- Swollen glands in the neck
- Swelling in the upper or lower jaw, which is considered a very serious sign
Warm saltwater rinses may ease discomfort, and an over-the-counter pain reliever can help with pain and fever. Never place aspirin directly on the tooth or gum — it can burn the tissue and cause mouth ulcers. An abscess will not go away on its own. Left untreated, the infection can spread to the jawbone, the bloodstream, or other parts of the body, so a dentist visit is necessary as soon as one is available, and any spreading facial or jaw swelling should be treated as an emergency.
Lost Filling or Crown
If a filling or crown falls out, the exposed area of the tooth can be sensitive and vulnerable to further damage. Over-the-counter temporary dental cement, sold at most pharmacies, can be used to cover the area following the product’s instructions. This is a short-term measure meant to protect the tooth until a dentist can place a permanent repair — it is not a fix on its own.
Building a Basic Dental Emergency Kit
A small, dedicated dental kit is a useful addition to your home first aid and preparedness supplies. Consider including:
- Sterile gauze pads for bleeding or bite-down support
- A small container with a secure lid, for transporting a knocked-out tooth
- Over-the-counter pain relievers appropriate for the people in your household
- Dental wax, to cover a sharp broken edge
- Temporary dental cement or filling material
- Cotton balls or swabs
- A small flashlight or headlamp for checking the mouth in low light
- Your dentist’s contact information, plus the number for the nearest urgent care or emergency room
This kit works best alongside the wider first aid and family communication planning covered in our emergency preparedness coverage, since dental injuries often happen alongside other emergencies rather than on their own.
Extra Caution for Certain Groups
Some people face higher risk from an untreated dental infection and should be especially cautious about delaying care:
- People with diabetes, since infections can be harder for the body to fight off
- People who are immunocompromised or taking medications that suppress the immune system
- People with certain heart conditions, since dental infections that spread can affect the heart
- Pregnant individuals, who should check with a health care provider before taking any medication, including over-the-counter pain relievers
- Young children, since a knocked-out baby tooth is handled differently than a permanent tooth

Frequently Asked Questions
Can I put a knocked-out tooth back in myself?
If you’re able to, gently placing the tooth back into its socket and biting down softly on gauze can help preserve it until you reach a dentist. Handle it only by the crown, never the root, and don’t force it if it doesn’t seat easily.
Is it okay to put aspirin directly on a painful tooth or gum?
No. Placing aspirin directly against the tooth or gum can burn the tissue and cause mouth ulcers. Aspirin should be swallowed as directed on the label, not applied topically.
How long can a tooth infection go untreated before it’s dangerous?
There’s no safe fixed timeline. An abscess will not resolve on its own, and the infection can keep spreading the longer it goes untreated. Any facial or jaw swelling, fever, or difficulty swallowing or breathing should be treated as an emergency regardless of how long the pain has been present.
What’s the difference between a dental emergency and a medical emergency?
A dental emergency, like a toothache, chipped tooth, or lost filling, generally needs a dentist but isn’t immediately life-threatening. It becomes a medical emergency when there’s spreading swelling, trouble breathing or swallowing, a possible broken jaw, uncontrolled bleeding, or fever with facial swelling. Those situations call for an emergency room, not a wait for a dental appointment.
