Do Cracked Teeth Heal? A Dentist’s Honest Answer
By Dr. Aliya Khan, DDS — Columbia University School of Dental and Oral Surgery, 20+ years in practice, Moorestown NJ
The Short Answer
No. Your tooth can’t heal itself.
I know that’s not what you wanted to hear. Skin closes back up. Bones knit themselves together. But teeth? They don’t have the cells for that. Once enamel cracks, it stays cracked — until a dentist fixes it.
Here’s the good news: I’ve been fixing cracked teeth for over 20 years, and in most cases, we can save the tooth. Sometimes with a 30-minute bonding fix. Sometimes with a crown. Occasionally with more. But rarely does a crack mean you’re losing the tooth.

Why Can’t Teeth Heal Themselves?
Quick anatomy lesson — just enough to make sense of what’s happening.
Your tooth has three layers:
1. Enamel — the hard white outer coat. It’s the toughest substance in your body. Harder than bone. But it has one weakness: it’s made of minerals, not living cells. No cells means no healing.
2. Dentin — the softer yellow-ish layer underneath. Still no living tissue that repairs damage.
3. Pulp — the innermost part with nerves and blood vessels. This is where “living tooth” starts. But by the time a crack reaches the pulp, you’re not talking about healing anymore — you’re talking about an infected tooth.
So when a crack starts in the enamel, it’s just a mineral fracture. There’s nothing there to grow back. It stays cracked, and often gets worse over time.
That’s why treating it matters.
What Kind of Crack Do You Have?
Not all cracks are created equal. Here’s how I categorize them, from “we can wait” to “call me right now.”
Craze Lines (The Ones You Can Usually Ignore)
Tiny surface lines you might notice in the mirror. They only affect the outer enamel — no pain, no sensitivity, no risk. Most adults have some, especially past age 40.
Do you need treatment? Usually no. If they bother you cosmetically, we can hide them with dental bonding.
Typical cost: $0 to $500
Wait time: Not urgent — bring it up at your next checkup.
Fractured Cusp (The “Broken Chunk” Kind)
You bit down on something hard and a piece of the chewing surface broke off. The tooth is still there, but it’s missing a corner. You might feel it with your tongue.
Do you need treatment? Yes. Without a crown, the crack usually spreads.
Typical cost: $800-$1,500 (crown)
Wait time: Within 1-2 weeks. Longer risks the crack spreading into the pulp.
Cracked Tooth (The One That Hurts When You Bite)
This is what most people mean when they say “cracked tooth.” A vertical crack running from the chewing surface toward the root. Often you get sharp pain when biting AND when you release pressure — that’s the classic sign.
Do you need treatment? Yes, and soon. If the crack reaches the pulp, you’ll need a root canal too.
Typical cost: $1,500-$2,500 (crown + often a root canal)
Wait time: Within 3-5 days. Every day increases the risk of pulp damage.
Split Tooth (The One We Might Not Save)
A crack that splits the tooth into two distinct pieces. Usually happens when a cracked tooth wasn’t treated for months or years.
Do you need treatment? Yes — but often the tooth can’t be saved. Depending on where the split is, we may save the tooth crown or extract the whole thing.
Typical cost: $3,500-$5,500 (extraction + dental implant). Wait time: As soon as possible.
Vertical Root Fracture (The Sneaky One)
The crack starts at the root and moves up. Usually there are few symptoms until infection develops. Only shows up on X-rays.
Do you need treatment? Yes. These almost always require extraction.
Typical cost: $3,500-$5,500 (extraction + implant)
Wait time: Whenever you find out about it. These are almost always caught at a routine checkup.
What To Do Right Now
If you just cracked a tooth (or think you did), here’s the game plan.
In the Next Hour
Rinse your mouth with warm salt water. One teaspoon of salt in a cup of warm water. Swish gently, don’t gargle. This cleans the area and reduces bacteria.
Cold compress on the outside of your cheek. Fifteen minutes on, fifteen off. Helps with swelling and takes the edge off pain.
Take ibuprofen (Advil). 400mg is fine for most adults. It’s better than acetaminophen (Tylenol) for dental pain because it reduces inflammation, not just pain.
Save any broken pieces. Put them in a small container of milk or in a cup with your own saliva. In some cases, we can reattach small pieces. Don’t count on it, but bring them to your appointment just in case.
Eat on the other side. Sounds obvious, but people forget. Also skip anything crunchy, chewy, or extreme temperature.
Don’t Do These Things
Don’t put aspirin on your gum or tooth. Old wives’ tale — actually causes a chemical burn. Take it orally instead if you don’t have ibuprofen.
Don’t try to glue anything back on. Not with superglue, not with any home remedy. You’ll just make my job harder when you come in.
Don’t ignore severe pain. Pain that ibuprofen doesn’t touch, or pain that keeps you up at night, means the crack has reached the pulp. That’s not something to sleep on.
Don’t drink through a straw right at the tooth. Suction can shift a loose piece. Drink from the other side of your mouth.
Call Us Immediately If:
- You have a fever (indicates infection)
- Your face or gum is visibly swollen
- The tooth feels loose
- Bleeding won’t stop
- Pain isn’t controlled by ibuprofen
- You bit down and a whole tooth came out

How Long Can You Actually Wait?
Everyone wants to know this, so let me be straight with you.
| What’s happening | When to see me |
|---|---|
| I see a hairline crack. No pain. | Bring it up at your next 6-month checkup |
| Small chip. No pain or sensitivity. | Within 1-2 weeks |
| Chip with mild sensitivity to cold | Within 1 week |
| Sharp pain when biting | Within 3-5 days |
| Sharp constant pain, sensitivity to everything | Within 24-48 hours |
| Pain + swelling or fever | TODAY. Emergency. |
The general rule I tell every patient: the sooner we treat a crack, the simpler the fix.
A crack that could have been fixed with bonding on Monday becomes a crown by Friday. A crown case becomes a root canal by the following week. Waiting rarely makes anything cheaper.
Your Four Treatment Options
When you come in for a cracked tooth, here’s what I’ll be considering.
Option 1: Bonding
For small cracks or chips that haven’t reached the dentin.
What happens: I remove the crack completely as if I am removing caries for a filling then fill the area with bonding . Or if the crack is caused by a silver filling I remove the silver filling replacing it with white bonding material that can keep the crack together No anesthesia in most cases.
How long it lasts: 5-10 years, sometimes longer.
Cost: $300-$500 per tooth.
Insurance: Usually covered as cosmetic-adjacent. Coverage varies.
Option 2: Crown
For fractured cusps or deeper cracked teeth. A crown is a custom-made cap that covers the entire top of your tooth.
What happens: First visit: I prep the tooth and take an impression. You leave with a temporary crown. Second visit (2-3 weeks later): I bond the permanent crown in place.
How long it lasts: 10-15 years, often 20+ with good care.
Cost: $800-$1,500 depending on material.
Insurance: Usually covered at 50%.
Option 3: Root Canal + Crown
If the crack has reached the pulp (the inside of your tooth), we need to clean out the infected tissue before crowning it.
What happens: Root canal removes the pulp, cleans and seals the canals. Then we place a crown to protect the tooth.
How long it lasts: 10-15 years for the crown; the underlying tooth structure lasts a lifetime with proper care.
Cost: $800-$1,600 (root canal) + $800-$1,500 (crown) = $1,600-$3,100 total.
Insurance: Usually covered at 50-80%.
Option 4: Extraction + Replacement
If the crack has split the tooth or affected the root, extraction is often the only option. Then we replace the tooth with an implant or bridge.
What happens: Tooth extraction takes 15-60 minutes depending on complexity. Implant placement happens either same day or after 2-3 months of healing.
How long it lasts: Implants can last a lifetime.
Cost: $200-$700 (extraction) + $3,000-$5,000 (implant) = $3,200-$5,700 total.
Insurance: Extraction usually covered. Implant coverage varies.
What Causes Cracked Teeth (So You Can Prevent the Next One)
You didn’t cause this. Bad luck happens. But here’s what typically leads to cracked teeth, and what you can do about it.
Chewing on hard things. Ice cubes are the #1 offender in my practice. Popcorn kernels are #2. Hard candy, jawbreakers, and chicken bones round out the list. Just… don’t.
Grinding or clenching (bruxism). If you grind your teeth at night, you’re putting 6-10x normal chewing force on them. Cracks are inevitable eventually. A custom nightguard from our TMJ treatment prevents this.
Large old fillings. Big silver fillings from decades ago left teeth structurally weakened. Cracks around them are common. Modern dentistry uses smaller, bonded fillings that preserve tooth strength.
Temperature shock. Biting into ice cream right after hot coffee. Or vice versa. Rapid temperature changes can crack enamel.
Trauma. Sports injuries, car accidents, falls. Even a fist-fight (I’ve seen it).
Age. Teeth do get more brittle with time. Nothing you can do about this except protect what you have.
Prevention basics:
- Wear a mouthguard for sports
- Wear a nightguard if you grind
- Skip the ice chewing
- Come in every 6 months so I can catch stress fractures before they become full cracks
Common Myths I Hear Every Week
“If it doesn’t hurt, it’s fine.”
Wrong. Many cracks are painless until they reach the pulp. By then, you’re looking at a root canal instead of a filling. Painless cracks are still cracks — they still spread.
“Only old people get cracked teeth.”
Also wrong. I’ve treated cracked teeth in patients from age 14 to 91. Teenagers with sports injuries. Adults who chew ice. Young professionals with high-stress grinding habits.
“A cracked tooth always means extraction.”
Definitely wrong. In most cases, we save the tooth. Extraction is the last resort, not the default.
“I can wait until my next regular appointment.”
Depends on the crack. For painless craze lines, yes. For a fractured cusp or sharp biting pain — no. Every week you wait, the tooth loses treatment options.
“My tooth broke while eating soft food, so it’s your fault.”
Actually, sometimes teeth just fail. Especially teeth with old fillings, previous root canals, or existing stress fractures. It’s not always something you did wrong.
Does Insurance Cover Cracked Tooth Repair?
Yes — most of it.
PPO dental insurance typically covers:
- Bonding: 50-80% coverage
- Crown: 50% coverage
- Root canal: 50-80% coverage
- Extraction: 80-100% coverage
- Implant: 0-50% coverage (varies significantly)
At Moorestown Smile Center, we accept most major plans:
- Aetna, Cigna, Delta Dental
- MetLife, Horizon, GEHA
- United Concordia, Careington
We verify your benefits BEFORE your appointment. You’ll know what’s covered and what you’ll owe before we start any work.
Don’t have insurance? We offer CareCredit and Proceed Finance. Payment plans that fit your budget.
When to See a Dentist — Not the ER
Dental emergencies aren’t emergency room emergencies (usually). Here’s the difference.
Go to an actual ER if:
- You can’t breathe properly due to swelling
- You have uncontrolled bleeding
- You have severe facial swelling extending to your neck or eye
- You have a high fever with dental pain
Call our office if:
- Cracked tooth with sharp pain
- Broken tooth
- Lost tooth (immediate care can sometimes save it)
- Severe toothache
- Swollen gums around a specific tooth
- Anything urgent but not life-threatening
I keep same-day emergency slots open every day. Call (856) 638-5266 as early as possible.
Frequently Asked Questions
No. Teeth don’t have the living cells needed for healing. Once enamel cracks, only a dentist can restore the tooth using bonding, crown, root canal, or extraction — depending on how deep the crack goes.
Cost depends on severity. Bonding for minor cracks: $300-$500. Crown: $800-$1,500. Root canal + crown: $1,600-$3,100. Extraction + implant: $3,200-$5,700. Most insurance plans cover 50% or more.
Craze lines are surface enamel cracks with no pain and no risk. Real cracks penetrate through enamel into dentin or pulp, cause sensitivity or pain, and require treatment.
That’s the classic sign of a cracked tooth. When you bite, the crack opens slightly. When you release pressure, it closes and irritates the nerve. This “biting pain” is a distinctive sign of cracked tooth syndrome.
Yes. Cracked teeth can trigger referred pain that shows up as jaw pain, ear pain, or even headaches. This is especially common with molar cracks and can be confused with TMJ issues or bruxism.
Not always. Small cracks and chips can be fixed with bonding. Crowns are needed when the crack has weakened the tooth structure or affected the chewing surface. Dr. Khan determines the right treatment after an exam.
Depends on the crack. Painless craze lines: no rush. Small chip without pain: 1-2 weeks. Biting pain: 3-5 days. Severe pain or swelling: same day. The general rule: sooner is always cheaper and less invasive.
Yes. When cracks reach the inner pulp, bacteria can enter and infect it. Signs of infection include throbbing pain, swelling, bad taste, fever, or a pimple on the gum. This requires immediate care.
A Personal Note From Dr. Khan
Cracked teeth scare people. I get it. You feel something break, you don’t know how bad it is, and you’re worried about pain, cost, and losing the tooth.
Here’s what I tell every patient: In 20+ years of practice, I’ve saved far more cracked teeth than I’ve extracted. Modern dentistry has made this a very treatable condition — as long as you come in before the crack spreads.
If you’re in pain right now, call us. If you’re not sure whether to come in, call us anyway — we can tell you over the phone whether it’s urgent or can wait.
You don’t have to wait until the pain gets worse. And you don’t have to be a current patient to see me for a cracked tooth. Just call.
