How to Fix a Broken Tooth Crown Temporarily

Last Updated: September 21, 2026

Step 1: Assess the Damage and Protect the Exposed Tooth

A broken tooth crown needs calm, quick action: once it comes loose, the tooth underneath is exposed and vulnerable. This guide from Rodney Street Dental shows how to fix a broken tooth crown temporarily until you can be seen.

Find the crown, check your mouth, pillow or the sink. If you swallow it, don't panic; it will pass safely. Rinse it gently with warm water and set it aside. If the tooth bleeds, bite on clean gauze or a damp tea towel for ten minutes.

Protect the exposed tooth, the dentine and pulp underneath become sensitive fast. Avoid hot and cold drinks, breathe through your nose and keep your tongue away from sharp edges. If the tooth feels jagged, cover it with dental wax from a pharmacy.

Watch Out Never force a crown back on if it doesn't sit comfortably. Forcing it can damage the tooth root and turn a simple repair into a much bigger problem.

If you can't reattach it, store the crown in a small container or a cup of milk, never tissue.

Step 2: Using Temporary Dental Cement for Crowns

Temporary dental cement is the best at-home option for reattaching a crown, available over the counter at most pharmacies. Follow the kit's mixing instructions closely.

Here's the basic process:

  1. Clean and dry the crown and tooth
  2. Mix the cement as directed
  3. Apply a thin layer inside the crown
  4. Seat it gently, bite down and hold firm pressure for two to three minutes

Don't use too much cement, excess can push the crown up and throw off your bite. Denture adhesive is too soft to hold a crown for long. Clove oil can ease sensitivity but won't fix the crown.

Pro Tip If the crown won't stay put, leave it off and keep the tooth clean. A poorly seated crown is worse than no crown at all.

After reattaching, avoid chewing on that side and skip anything sticky or hard.

Step 3: When to Seek Emergency Dental Care for a Broken Crown

Not every broken crown is a dental emergency, but some are. Call an emergency dentist straight away if you have:

  • Severe or throbbing pain that won't settle
  • Bleeding that won't stop after ten minutes
  • A swollen face, jaw or gum
  • A loose or shifted tooth
  • Signs of infection, like fever or a bad taste

These signs suggest the dental pulp may be involved, and a broken tooth crown that exposes the pulp raises the risk of infection. Even without pain, book an appointment within a few days so a dentist can check the abutment and gingival tissue.

Situation What to Do Urgency
Crown off, no pain Reattach with temporary cement Book within days
Sharp edge, mild sensitivity Cover with dental wax Book within days
Severe pain or swelling Call an emergency dentist Same day
Bleeding that won't stop Seek urgent care Immediately

Emergency care focuses on relieving pain and protecting the tooth; a dentist may reshape the crown, fit a temporary restoration or plan a permanent cement fix later.

Looking After the Tooth Until Your Appointment

A temporary fix buys you time, not a cure. Keep the area clean. Brush gently around the tooth and rinse with warm salt water.

  • Use a soft-bristled brush
  • Avoid flossing tightly around the crown
  • Skip sugary snacks and fizzy drinks

Watch for changes. New pain, a bad smell, or a loose crown all mean you should call sooner.

Key Takeaway Temporary cement holds a crown for days, not weeks. Book a dental appointment as soon as you can to avoid long-term damage.

If the tooth is fractured below the gum line, no home fix will work. That needs a dentist.

Preventing Future Crown Problems

Good habits keep crowns in place longer.

  • Avoid chewing ice, pens or hard sweets
  • Wear a mouthguard if you grind your teeth
  • Keep up with check-ups and treat gum disease early

Occlusal pressure from grinding is a common cause of crown failure. A night guard can help. If a crown keeps coming loose, the abutment may need review. Don't keep reattaching it yourself.


A broken crown is unsettling, but it rarely means a lost tooth.

Frequently Asked Questions

My temporary crown broke off on the weekend. What should I do?

If your temporary crown comes off over the weekend, keep the area clean and avoid chewing on that side. You can use over-the-counter temporary dental cement from a pharmacy to reattach it if the crown is intact. If you have pain, swelling, or the tooth is fractured, contact an emergency dentist. Do not use superglue. A broken tooth crown needs professional assessment to prevent infection or further damage.

How long can I leave a broken crown before seeing a dentist?

A temporary fix is not a long-term solution. You should see a dentist within a few days, ideally 24 to 48 hours. Leaving a broken tooth crown untreated exposes the tooth to bacteria, which can lead to infection, sensitivity, and further fracture. If you cannot get an appointment quickly, keep the area clean and use temporary dental cement for crowns as a short-term measure, but do not delay professional care.

Can I use superglue to fix a broken crown at home?

No. Superglue is toxic and not designed for use in the mouth. It can damage the tooth, irritate gums, and make professional repair more difficult. Only use temporary dental cement for crowns that is specifically made for oral use and available from a pharmacy. If you are unsure, leave the crown out and protect the exposed tooth with dental wax or sugar-free chewing gum until you can see a dentist.
