Dental Emergencies: What to Do and When to See a Dentist

Dental emergencies rarely arrive at a convenient time. A sudden toothache, a chipped tooth at a family gathering, a knocked-out tooth on the rink — it can be overwhelming to figure out what to do when you’re caught off guard. Knowing how to respond quickly can reduce pain, prevent complications, and sometimes even save a tooth.

Here’s a practical guide to handling the most common dental emergencies at home before you can reach our office or an emergency clinic.

What counts as a dental emergency?

A dental emergency is any situation involving your teeth, gums, or mouth that needs prompt attention to stop bleeding, relieve severe pain, or save a tooth. Common examples include:

• Severe toothache
• Chipped or broken tooth
• Knocked-out tooth
• Lost filling or crown
• Swelling, abscess, or infection
• Injury to the gums, lips, or tongue

Accidents, sports injuries, untreated decay, and infections are the usual culprits. If you experience severe pain, swelling, or trauma to your mouth, call our office at (613) 932-2058 as soon as possible — we’ll help you directly or point you to the nearest emergency clinic.

Severe toothache

1. Rinse your mouth with warm salt water to clear away irritating debris.
2. Gently floss to remove any food trapped between teeth.
3. If there’s swelling, hold a cold compress against your cheek to ease pain and swelling.
4. Over-the-counter pain relievers such as ibuprofen or acetaminophen can help until you see a dentist.

A persistent toothache may signal decay, infection, or gum disease — don’t wait it out. If the tooth’s nerve is involved, timely root canal treatment can relieve the pain and save the tooth.

Chipped or broken tooth

1. Rinse your mouth gently with warm water.
2. Recover any pieces of the tooth and store them in milk or slightly salted water.
3. If there’s bleeding, hold a small piece of gauze on the area until it stops.
4. Apply a cold compress to your cheek to reduce pain and swelling.
5. Seek treatment promptly — depending on the severity, the tooth may be repaired with bonding, a filling, or a crown.

Knocked-out tooth

Time matters most here — a knocked-out tooth has the best chance of being saved if it’s replanted within 30 minutes to an hour.

1. Pick the tooth up by the crown (the top), never the root.
2. If it’s dirty, rinse it gently with water — don’t scrub.
3. Try placing it back into the socket without pushing or forcing it.
4. If it won’t slip back in, put the tooth in a small clean container of milk or slightly salted water.
5. Call our office immediately.

Abscess or swelling

An abscess is an infection around the tooth root or in the space between your gums and teeth. If you notice a pimple-like bump or swelling on your gums, call your dentist as soon as possible — infections can spread. In the meantime, rinse with warm salt water several times a day to draw pus to the surface and ease pain and swelling.

Lost filling or crown

A lost filling or crown leaves the tooth exposed and vulnerable. Avoid chewing on that side of your mouth, and place a small piece of sugar-free gum over the open cavity as a temporary cover. Then contact our office to repair or replace the restoration.

Something stuck between your teeth

Use dental floss to gently work the object free — the sooner the better, before it irritates or infects the gums. Never use a sharp object to dig it out; that can cut your gums or scratch the tooth surface. If you can’t remove it, give us a call.

Cuts to the gums, lips, or tongue

Rinse with water, apply pressure with gauze, and use a cold compress for swelling. If the bleeding won’t stop, seek immediate medical attention.

When to go to the emergency room instead

Some injuries need urgent medical care rather than a dental appointment. Go to the nearest emergency department if you have:

• Severe bleeding that won’t stop
• Difficulty breathing or swallowing
• Significant facial swelling
• Signs of a head injury or loss of consciousness

Preventing dental emergencies

Accidents happen, but you can lower your risk considerably:

• Wear a custom mouthguard for sports
• Avoid chewing ice, hard candy, and other very hard foods
• Never use your teeth to open packages
• Keep up with regular brushing, flossing, and check-ups — preventive visits catch problems before they become emergencies
• Around the holidays, go easy on hard and sticky treats, and if you have dental insurance, use it for needed treatment before your coverage resets in the new year

FAQ

What should I do first in a dental emergency?

Stay calm, rinse your mouth with warm water, control any bleeding with gauze, and call your dentist right away. For a knocked-out tooth, act fast — keep it moist in milk or slightly salted water and try to be seen within the hour.

Can a knocked-out tooth really be saved?

Often, yes — if you act quickly. A knocked-out adult tooth has the best chance of being saved when it’s replanted within 30 minutes to an hour. Handle it by the crown only, keep it moist, and get to a dentist immediately.

Is a severe toothache an emergency?

A persistent, severe toothache can signal decay, infection, or gum disease, and it won’t resolve on its own. Rinse with warm salt water, use over-the-counter pain relief, and book a dental visit promptly — waiting risks a worse infection.

When should I go to the hospital instead of the dentist?

Go to the emergency department for severe bleeding that won’t stop, difficulty breathing or swallowing, significant facial swelling, or any sign of head injury or loss of consciousness. For tooth-specific problems, your dentist is the right call.
