A broken tooth is an emergency when it causes severe pain, strong sensitivity to hot or cold, bleeding from inside the tooth, a visible pink or red spot in the centre of the break, a sharp edge cutting your mouth, or when a large part of the tooth is missing. A small chip with no pain or sharp edges can usually wait for a regular appointment, although it should still be checked. This guide explains how to tell whether a broken tooth is urgent, what to do with a chipped tooth right away, the repair options a dentist may suggest, and when to go to the hospital.
How Can You Tell If a Broken Tooth Is an Emergency?
What you notice | What it may mean | How urgent |
Small chip, no pain, smooth edge | Enamel-only damage | Book a regular appointment |
Rough or sharp edge cutting your tongue or cheek | Enamel or dentine damage | Book soon; protect the edge |
Sensitivity to hot or cold | Inner layer (dentine) may be exposed | Book a prompt appointment |
Pink, red, or bleeding spot in the break | Nerve (pulp) may be exposed | Same-day care |
Large piece missing or tooth split | Major structural damage | Same-day care |
Severe or throbbing pain | Nerve damage or infection | Same-day care |
Swelling, fever, or bad taste | Possible infection | Same-day care; hospital if breathing or swallowing is affected |
Teeth have three main layers. Enamel is the hard outer surface, dentine is the softer layer beneath it, and the pulp in the centre contains nerves and blood vessels. The deeper a break goes, the more urgent it usually is.
What to Do Right Away With a Broken or Chipped Tooth
- Rinse gently with warm water to clean the area.
- Save any pieces in a clean container. Keeping them moist in milk or saliva can help if bonding them back is an option.
- Control bleeding with gentle pressure using clean gauze.
- Reduce swelling with a cold compress on the outside of your cheek.
- Protect your mouth by covering a sharp edge with dental wax or sugar-free gum.
- Manage pain with over-the-counter pain relief taken as directed on the package.
- Contact a dentist and describe what happened and how it feels.
Avoid chewing on the broken tooth, very hot or cold food and drinks, and anything hard or sticky until you are seen.
What to Do With a Chipped Tooth That Does Not Hurt
A small chip with no pain, no sensitivity, and no sharp edges is usually not urgent. Still book an appointment soon. Even small chips can weaken the tooth, collect plaque, or develop into larger cracks over time. A dentist can smooth the edge or repair it with tooth-coloured bonding. In the meantime, avoid biting hard foods on that tooth.
When Should You Go to the Hospital Instead?
Go to the nearest emergency department or call 911 if a broken tooth comes with:
- Bleeding that will not stop with steady pressure
- Swelling that affects breathing, swallowing, or your eye
- A possible broken jaw or serious facial injury
- A head injury, dizziness, or loss of consciousness
Hospitals manage serious injuries and swelling, while dental repair is usually done by a dentist afterward. The ADA’s MouthHealthy guide to dental emergencies also covers broken teeth.
Types of Broken Teeth
Minor chip
A small piece of enamel breaks off, often from a front tooth. Often causes no pain and is repaired with smoothing or bonding.
Fractured cusp
A pointed chewing surface on a back tooth breaks, often around a large filling. It may feel sharp but is often not painful. A filling, onlay, or crown is often used to restore it.
Cracked tooth
A crack runs from the chewing surface toward the root. It can cause sharp pain when biting or releasing, or sensitivity to temperature. Early treatment can help prevent the crack from spreading.
Split tooth
A crack has separated the tooth into parts. Depending on where the split is, part of the tooth may be saved, but sometimes extraction is needed.
Vertical root fracture
A crack starts in the root and may cause few symptoms until infection develops. It is often found on X-rays and may require extraction.
What Happens at Your Emergency Visit?
- Assessment: the dentist asks what happened, checks the tooth, gums, bite, and soft tissues, and looks for other injuries.
- X-rays: these show how deep the break goes and whether the root or bone is affected.
- Options explained: you hear what is wrong, your options, and the costs before treatment.
- Pain relief and protection: the first step is relieving pain and protecting the tooth, sometimes with a temporary filling or crown.
- Follow-up: some repairs are finished the same day; others need another visit.
How Is a Broken Tooth Repaired?
Treatment | When it may be used |
Smoothing | Very small chips with no sensitivity |
Bonding | Small to moderate chips, especially on front teeth |
Filling | Breaks involving part of a back tooth |
Crown | Large breaks or weakened teeth needing full coverage |
Veneer | Front teeth with chips or cosmetic concerns, in selected cases |
Root canal therapy | Breaks that expose or damage the nerve |
Extraction | Teeth that cannot be saved, such as some split teeth |

Can a Broken Tooth Be Fixed the Same Day?
Sometimes. Smoothing and bonding a small chip can often be done in a single visit. Larger repairs, such as a crown, may need a temporary restoration first and a second appointment. If the nerve is involved, root canal therapy may be started to relieve pain and then completed later.
What Causes Teeth to Break?
- Biting hard foods, ice, or hard candy
- Falls, sports injuries, and accidents
- Large old fillings that weaken the tooth
- Decay that undermines the tooth structure
- Grinding or clenching, especially at night
- Teeth that have had root canal treatment without a crown, in some cases
How Can You Prevent a Broken Tooth?
- Wear a mouthguard for contact sports and activities with a fall risk.
- Avoid chewing ice, hard candy, and popcorn kernels.
- Do not use your teeth to open packages or bottles.
- Ask about a night guard if you grind your teeth.
- Keep up check-ups so weak fillings and cracks are found early.
Broken Teeth in Children
Children often chip or break teeth during play and sports. Stay calm, find any pieces, control bleeding with gentle pressure, and contact a dentist promptly. For baby teeth, the dentist will check the injury and the developing adult tooth underneath. Go to hospital for serious facial injuries, uncontrolled bleeding, or any head injury.
Broken Tooth Emergency Checklist
Do | Avoid |
Rinse gently with warm water | Chewing on the broken tooth |
Save pieces in milk or saliva | Very hot, cold, hard, or sticky food |
Apply gentle pressure for bleeding | Placing aspirin on the gum |
Use a cold compress for swelling | Ignoring a crack that does not hurt |
Cover sharp edges with dental wax or gum | Trying to glue a tooth yourself |
Contact a dentist promptly | Waiting if pain or swelling worsens |
Broken Front Tooth vs. Broken Back Tooth
A broken front tooth is often noticed right away because it affects your smile, and repair options such as bonding or a veneer focus on both appearance and protection. A broken back tooth may not be visible, but back teeth take heavy chewing forces, so even a small break can grow. Back teeth with large fractures often need a crown or onlay for strength. Either way, prompt assessment helps protect the tooth.
What If a Filling or Crown Breaks?
A broken or lost filling or crown can leave the tooth sensitive and weaker. Keep any crown that comes off and bring it with you, since it may be possible to re-cement it. Avoid chewing on that side, keep the area clean, and use temporary filling material from a pharmacy only as a short-term measure. Book an appointment soon, and sooner if there is pain.
Can a Cracked Tooth Be Saved?
Many cracked teeth can be saved, especially when found early. A crack limited to the crown may be protected with a crown. If the crack reaches the nerve, root canal therapy may also be needed. Cracks that extend deep into the root are harder to treat and may require extraction. Because cracks can be hard to see, sharp pain when biting or releasing is worth having checked even if the tooth looks normal.
What Does Broken Tooth Repair Cost?
Cost depends on the type of repair, such as bonding, a filling, a crown, or root canal therapy, and whether more than one visit is needed. Many dental plans cover part of these treatments. Ask for an estimate before treatment so you understand the options and your share of the cost.
Protecting a Repaired Tooth
After a broken tooth is repaired, a few habits help it last:
- Avoid biting hard objects, ice, and pens.
- Wear a mouthguard for sports and a night guard if you grind.
- Brush and clean between teeth daily, paying attention to the edges of bonding or crowns.
- Keep up regular check-ups so the repair can be monitored.
Common Myths About Broken Teeth
- “If it doesn’t hurt, it doesn’t need treatment.” Chips and cracks that do not hurt can still grow or collect plaque.
- “A broken tooth always means extraction.” Many broken teeth can be repaired with bonding, a crown, or root canal therapy.
- “The ER can fix a broken tooth.” Hospitals manage serious injuries, but dental repair usually needs a dentist.
- “A crack will heal on its own.” Teeth do not heal cracks the way bones do.
What to Do With a Chipped Tooth: Summary
Rinse, save the piece, protect sharp edges, avoid chewing on that side, and book an appointment. If there is pain, sensitivity, a pink or red spot, or swelling, contact a dentist the same day. Most chipped teeth can be repaired, and early care helps prevent a small chip from becoming a larger break.
Broken Teeth and Dental Anxiety
A broken tooth can be stressful, especially if you feel nervous about dental visits. Tell the team when you call so they can explain each step, go at a comfortable pace, and discuss comfort options. Getting the tooth assessed early often means simpler treatment, which can make the experience easier overall.
