Cracked a tooth? Here's what to do in the next hour.

Cracked teeth are one of the most common dental emergencies we see — usually from biting unexpectedly hard food (popcorn kernels, ice, hard candy), a fall, or a sports injury. Most are fixable. Some are urgent. Here's how to tell the difference and what to do right now.

First, figure out what kind of crack you have

Not all cracks are equal. The key categories:

  • Craze lines — tiny surface cracks in enamel only. Visible but painless. No treatment needed.
  • Chipped tooth — a small piece broken off the edge or corner. Usually no pain unless deep. Cosmetic fix or small bonded filling.
  • Cracked tooth (visible crack across the tooth) — the most variable. Pain when biting, sensitivity to cold or sweet. Needs evaluation soon.
  • Split tooth — the crack has separated the tooth into pieces. Usually severe pain. Needs immediate care; may not be savable.
  • Vertical root fracture — crack runs down into the root. Pain is variable. Usually requires extraction.

In the first hour

1. Save any tooth fragments. Rinse them gently in water and put them in a small container with milk, saliva, or saline. We may be able to bond a fragment back if it's a clean break and you act quickly (within 24 hours).

2. Rinse your mouth with warm salt water. A teaspoon of salt in a cup of warm water — gentle rinse, don't swish hard. This cleans the area and reduces bacteria.

3. Manage pain with ibuprofen. 600 mg every 6 hours works well for most dental pain (assuming you have no contraindications). Avoid aspirin if you're still bleeding.

4. Cold compress on the cheek — 15 minutes on, 15 off. Reduces swelling.

5. Avoid chewing on that side. Bite on the other side until you've been seen.

6. Call us. (719) 647-9433. We hold same-day emergency slots open every weekday.

When to skip the dentist and go to the ER

The ER, not a dentist, is the right call when:

  • The crack is part of a larger jaw or facial trauma
  • You can't close your mouth normally
  • You're bleeding heavily and it won't stop with pressure
  • You're having difficulty breathing or swallowing
  • There's significant facial swelling spreading rapidly
  • You hit your head and may have a concussion

The ER will stabilize you medically. Then we'll see you for the dental side after. For pure dental emergencies (cracked tooth, no other injury), the ER will only give you antibiotics and a referral — they don't do dental work.

What we'll do at the visit

Three steps: examine, X-ray, plan.

The exam tells us how deep the crack is, whether the nerve is involved, and whether the tooth is savable. X-rays show the root and any spread of damage below the gum line. Some cracks need a 3D scan (CBCT) to see clearly.

From there, treatment depends on what we find:

  • Small chip or surface crack: Bonded filling or smoothing. Quick, often same visit. $150–$400.
  • Crack into dentin (no nerve damage): Crown to hold the tooth together. Often a same-day CEREC crown. $1,000–$1,800.
  • Crack reaching the nerve: Root canal followed by crown. ~$2,000–$3,200 total.
  • Split or vertical root fracture: Extraction, usually followed by an implant. $4,000–$6,000 for the complete replacement.

Why some cracks heal and others don't

Tooth structure doesn't heal the way bone does. A crack in enamel won't close on its own. What can change is whether the crack stays small or spreads — and that depends on what you do next.

Cracks left untreated tend to grow. Each chew adds stress. Eventually the crack reaches the nerve (toothache), or the tooth splits in half (extraction). Catching cracks early — before they cause severe pain — is what gives you the best treatment options.

Even if the cracked tooth doesn't hurt much, get it looked at within a week. Pain isn't a reliable indicator of how serious a crack is.

FAQ

Common questions

  • How urgent is a cracked tooth that doesn't hurt?

    Get it evaluated within a week. Painless cracks can be small surface cracks (no treatment needed) or deeper cracks that just haven't reached the nerve yet. The exam tells us which. Don't wait for pain — by the time it hurts, treatment options are usually more invasive and expensive.

  • Can a cracked tooth heal on its own?

    No. Tooth structure doesn't regenerate the way bone does. A crack in enamel stays a crack until it's restored. What's variable is whether the crack stays small or grows over time — and that depends on bite forces and treatment.

  • Should I use temporary tooth repair material from the drug store?

    Only as a stopgap. Drug-store dental cement (like Dentemp) can fill a hole or hold a piece in place for a day or two if you can't get to a dentist. It's not a real fix and shouldn't replace seeing us. If you use it, come in within a few days for a real evaluation.

  • What if I broke a back molar — can I just leave it?

    Not recommended. Even if it doesn't hurt now, the cracked surface gives bacteria easy access to the inside of the tooth. Decay and infection set in over weeks to months. Most "I just left it" stories end with extraction and an implant 6 months later, which costs far more than a crown would have.

  • How can I prevent cracked teeth?

    Wear a night guard if you grind your teeth (a major cause of cracks in adults). Avoid biting hard objects — ice, popcorn kernels, hard candy, pen caps, fingernails. Wear a mouthguard for contact sports. And don't ignore small cracks; treating them early prevents them from becoming big cracks.
