How to Handle Common Dental Emergencies: A Practical Guide

Dental emergencies can happen to anyone at any time. Knowing how to respond quickly and correctly can mean the difference between saving and losing a tooth, and can significantly reduce pain and complications. This guide provides practical, step-by-step instructions for managing the most common dental emergencies before you reach your dentist.

What Qualifies as a Dental Emergency?

A dental emergency is any dental problem that requires immediate attention to stop bleeding, alleviate severe pain, or save a tooth. True dental emergencies include:

• A knocked-out (avulsed) permanent tooth
• A severely broken or fractured tooth with exposed nerve
• Uncontrollable bleeding from the mouth
• Severe dental infection with facial swelling or difficulty breathing
• A displaced or loosened tooth from trauma

Situations that require prompt but not necessarily immediate care include toothaches, lost fillings, broken crowns, and minor chips. For a comprehensive list, see our guide to the top 10 dental emergencies and how to handle them.

Knocked-Out Tooth

A knocked-out permanent tooth is the most time-sensitive dental emergency. The chances of successful reimplantation decrease significantly with every minute the tooth is outside its socket. If handled properly, a knocked-out tooth can be successfully replanted with a survival rate of over 90 percent when reimplanted within 5 minutes.

What to Do:

1. Find the tooth and pick it up by the crown (the white part you normally see). Never touch the root.
2. If the tooth is dirty, gently rinse it with milk or saline solution for no more than 10 seconds. Do not scrub it, use soap, or wrap it in tissue.
3. Try to reimplant the tooth by gently pushing it back into the socket with your fingers. Bite down on a clean cloth to hold it in place.
4. If you cannot reimplant it, place the tooth in one of the following storage media (listed in order of preference):
   • Milk (whole or low-fat)
   • Saline solution
   • The patient’s saliva (tuck it between the cheek and gum if the patient is old enough not to swallow it)
   • Water (as a last resort)
5. Get to a dentist within 30 minutes. Time is critical. The best outcomes occur when the tooth is reimplanted within 20 to 60 minutes.

Important: Baby teeth that are knocked out should not be reimplanted, as doing so can damage the developing permanent tooth underneath.

Severe Toothache

A severe toothache often indicates an infection, deep cavity, or cracked tooth that needs professional treatment. While you cannot treat the underlying cause at home, you can manage the pain until your dental appointment.

What to Do:

1. Rinse your mouth with warm salt water (half a teaspoon of salt in eight ounces of water) to help reduce inflammation
2. Floss gently around the tooth to remove any trapped food that may be contributing to the pain
3. Take over-the-counter pain medication such as ibuprofen (reduces both pain and inflammation) or acetaminophen
4. Apply a cold compress to the outside of the cheek for 15 to 20 minutes if there is swelling
5. Do not place aspirin directly on the gum tissue (this causes chemical burns)
6. Avoid very hot, cold, or sweet foods and beverages
7. Contact your dentist for an appointment as soon as possible

When a Toothache Is an Emergency:

Seek immediate care if the toothache is accompanied by:

• Facial swelling that is spreading
• Fever
• Difficulty swallowing or breathing
• A foul taste from drainage in the mouth

These symptoms may indicate a serious infection that requires urgent treatment.

Broken or Chipped Tooth

The urgency of a broken tooth depends on how much of the tooth is damaged and whether the nerve is exposed.

What to Do:

1. Rinse your mouth with warm water to clean the area
2. Save any broken pieces in milk or saline and bring them to your appointment
3. Apply gauze to any bleeding area with gentle pressure for 10 minutes
4. Apply a cold compress to reduce swelling
5. Cover sharp edges with dental wax or sugar-free gum to protect your tongue and cheeks
6. Avoid chewing on the affected side
7. See your dentist as soon as possible, especially if the break is large or the tooth is painful

Lost Filling or Crown

A lost filling or crown is uncomfortable but usually not a true emergency. However, the exposed tooth is vulnerable to further damage and sensitivity.

Lost Filling:

1. Clean the cavity gently with warm water
2. Place temporary filling material (available at pharmacies) or sugar-free gum into the cavity as a temporary seal
3. Avoid chewing on that side
4. See your dentist within a few days

Lost Crown:

1. Keep the crown and bring it to your appointment
2. Clean the crown and the tooth gently
3. Temporarily reattach the crown using denture adhesive, toothpaste, or over-the-counter temporary dental cement (do not use household glue)
4. See your dentist within a few days to have the crown properly recemented or replaced

Dental Abscess

A dental abscess is a bacterial infection that creates a pocket of pus in the tooth, gum, or jawbone. It is a serious condition that can spread to other parts of the body if left untreated.

Signs of a Dental Abscess:

• Severe, persistent, throbbing toothache
• Sensitivity to hot and cold temperatures
• Swelling in the face, cheek, or neck
• Tender, swollen lymph nodes
• Fever
• A pimple-like bump on the gum that may drain foul-tasting fluid

What to Do:

1. Rinse with warm salt water several times a day to draw the infection toward the surface and reduce pain
2. Take pain medication as needed
3. See your dentist urgently – dental abscesses require professional treatment with drainage and antibiotics
4. Go to the emergency room if you have difficulty breathing, swallowing, or if facial swelling is severe or spreading rapidly

Soft Tissue Injuries

Cuts, tears, or puncture wounds to the lips, tongue, cheeks, or gums can bleed significantly and cause alarm.

What to Do:

1. Rinse gently with warm salt water
2. Apply pressure with clean gauze or a moist tea bag for 15 to 20 minutes
3. Apply a cold compress to the outside of the mouth to reduce swelling
4. If bleeding does not stop after 20 minutes of continuous pressure, go to the emergency room

Building a Dental Emergency Kit

Keep these items at home and when traveling:

• Over-the-counter pain medication (ibuprofen and acetaminophen)
• Sterile gauze pads
• A small container with a lid (for a knocked-out tooth)
• Dental wax or temporary filling material
• Temporary dental cement
• Salt (for salt water rinses)
• Contact information for your dentist and nearest emergency dental clinic

Frequently Asked Questions

Should I go to the emergency room for a dental emergency?

Go to the emergency room if you have uncontrolled bleeding, difficulty breathing or swallowing, severe facial swelling, a jaw fracture, or signs of a life-threatening infection. For dental pain, lost fillings, and non-life-threatening issues, a dentist is usually better equipped to help than an emergency room.

Can a knocked-out tooth be saved?

Yes, if you act quickly. A knocked-out permanent tooth has the best chance of survival if it is reimplanted within 20 to 60 minutes. Keep the tooth moist in milk and get to a dentist immediately.

How do I know if my tooth is infected?

Signs of tooth infection include persistent throbbing pain, swelling around the tooth or in the face, a bad taste in the mouth, fever, and a pimple-like bump on the gum. If you suspect an infection, see your dentist promptly, as dental infections can become serious if untreated.

What should I do if my child knocks out a baby tooth?

Do not try to reimplant a baby tooth, as this can damage the developing permanent tooth underneath. Control any bleeding with gauze, apply a cold compress for swelling, and see your dentist to ensure no other teeth or the jawbone were damaged.
