What to Do During a Dental Emergency

A dental emergency needs calm, quick action. What you do in the first 30 minutes can determine whether a tooth is saved or lost.

Dental emergencies range from a knocked-out tooth to sudden severe pain that wakes you at 3am. Most people have never been told what to do in these situations, and the wrong first-aid response can make the outcome worse. Placing a knocked-out tooth in water instead of milk, for example, kills the root cells within minutes.

This guide covers the most common dental emergencies, what to do immediately for each one, and when to head to the emergency department instead of a dental clinic.

What Counts as a Dental Emergency

Not every dental problem is an emergency, and knowing the difference helps you respond appropriately. A dental emergency is any situation involving uncontrolled bleeding, severe pain that does not respond to over-the-counter pain relief, trauma to the teeth or jaw, or a sudden infection causing facial swelling.

Situations that typically require urgent dental care:

• A tooth that has been knocked out completely (avulsed)
• A tooth that has been pushed out of position or loosened by trauma
• A broken or fractured tooth with exposed nerve (sharp pain, visible pink tissue)
• Severe toothache that does not respond to ibuprofen or paracetamol
• Facial swelling from a dental abscess (can spread if untreated)
• A broken crown, bridge, or denture causing pain or soft tissue injury
• Uncontrolled bleeding after an extraction or injury

A chipped tooth with no pain, a lost filling that is not causing discomfort, or a minor crack can usually wait for a standard appointment within a few days. Anything involving active bleeding, severe pain, swelling, or a displaced tooth needs same-day attention.

What to Do if a Tooth Gets Knocked Out

A knocked-out adult tooth can sometimes be replanted successfully if you act within 30 to 60 minutes. The cells on the root surface need to stay alive, and how you handle and store the tooth in those first minutes is what matters most.

1. Pick up the tooth by the crown (white part) only. Do not touch the root. The root surface has cells called periodontal ligament cells that are needed for reattachment.
2. If the tooth is dirty, rinse it gently under milk or saline. Do not scrub the root, do not use tap water for more than a few seconds, and do not wrap the tooth in tissue.
3. Try to place the tooth back in the socket. Push it in gently with your fingers and bite down on a clean cloth to hold it in place.
4. If you cannot replant it, store it in cold milk. Milk has the right pH and osmolality to keep root cells alive for up to an hour. Saline is the next best option. Tap water damages the cells rapidly.
5. Get to a dentist within 30 minutes if possible. The longer the tooth is out of the socket, the lower the chance of successful replantation.

Baby teeth that get knocked out are not replanted. If a child loses a baby tooth from trauma, apply gentle pressure with gauze and see a dentist to check for damage to the developing adult tooth underneath.

What to Do for a Broken or Chipped Tooth

A broken tooth ranges from a minor chip to a fracture that exposes the nerve. The urgency depends on whether you can see pink or red tissue inside the break, and how much pain you are in.

For a minor chip or crack with no pain:

• Rinse your mouth with warm salt water
• Apply dental wax or sugar-free gum over any sharp edges to protect your tongue and cheek
• Book a standard appointment within a few days

For a larger break with pain or visible nerve tissue:

• Rinse with warm salt water
• Apply a cold compress to the outside of your cheek (20 minutes on, 20 minutes off)
• Take ibuprofen for pain and inflammation (follow packet directions)
• Do not apply aspirin directly to the tooth or gum
• See a dentist the same day if possible

A broken tooth may need a crown, root canal treatment, or extraction depending on the severity. Your dentist can assess the fracture and recommend the most appropriate treatment after an X-ray.

What to Do for Severe Toothache

Sudden severe toothache is usually caused by an infection reaching the nerve of the tooth (pulpitis) or an abscess forming at the root tip. Both need professional treatment. Home first aid manages the pain until you can get to a dentist, but it does not treat the underlying cause.

1. Rinse with warm salt water (half a teaspoon of salt in a glass of warm water). This can help draw out minor infection and reduce inflammation.
2. Take over-the-counter pain relief. Alternating ibuprofen and paracetamol every 3 to 4 hours is generally more effective than either alone. Follow the dosage on the packet.
3. Apply a cold compress to the outside of your cheek if there is swelling.
4. Do not place aspirin or any painkiller directly on the gum. This causes chemical burns to the soft tissue.
5. Avoid very hot, very cold, or sweet food and drinks until you see a dentist.

If the toothache is accompanied by facial swelling, fever, difficulty swallowing, or difficulty breathing, go to a hospital emergency department. Dental infections can spread into the neck and airway, and this requires urgent medical treatment beyond what a dental clinic can provide.

When to Go to Hospital Instead of a Dentist

Most dental emergencies are best treated by a dentist, not a hospital emergency department. Hospitals generally do not have dental equipment and can only provide pain relief and antibiotics until you see a dentist. However, some situations need a hospital first.

The key indicators for hospital over dentist are airway compromise, spreading infection, and uncontrolled bleeding. If in doubt, call your dentist first. Most dental clinics have an after-hours message with instructions for emergency situations.

How to Reduce Your Risk of Dental Emergencies

Most dental emergencies fall into two categories: trauma (sports injuries, falls, accidents) and infection (untreated decay or gum disease progressing to an acute episode). You can reduce the likelihood of both.

• Wear a custom mouthguard for any contact sport or activity with a risk of facial impact
• Keep up with regular check-ups and cleans to catch decay and gum disease before they become emergencies
• Do not use your teeth to open packaging, bottles, or anything that is not food
• Address cracked or weakened teeth early with a crown or filling rather than waiting for them to break
• If you grind your teeth at night, a nightguard protects against fractures

The Australian Dental Association recommends dental check-ups at least once a year, though patients with gum disease or high decay risk may benefit from visits every six months. Catching problems early is the most effective way to avoid a dental emergency.
