Chipped or Broken Tooth: What to Do and How It Gets Fixed
It usually happens at the worst possible moment. A bite of crusty bread, a cricket ball at Saturday training, a slip on the trampoline. Then your tongue finds a sharp edge that wasn't there this morning.
The good news? A chipped or broken tooth can usually be repaired, often in a single visit. How it gets fixed depends on how deep the break goes, and what you do in the first hour can make the repair simpler.
At Bradbury Dental Surgery in Campbelltown, we see chipped and broken teeth almost every week. Some are tiny corner chips on a front tooth. Others are back teeth that have split around an old filling. Here's what to do straight away, how to tell how serious it is, and how each type of break is repaired.
What Should You Do Right After Chipping or Breaking a Tooth?
Rinse, find the broken piece, protect the sharp edge and call a dentist. Here's the order we'd follow:
Rinse your mouth with warm water. It clears blood and grit so you can see what's happened.
Find the broken piece if you can. Keep it moist in milk, saline or a little water and bring it with you. A fragment can often be bonded straight back on.
Stop any bleeding. Press clean gauze or a damp tea bag on the area for 10 minutes.
Cover the sharp edge. Dental wax from the chemist (or a piece of sugar-free gum) stops it cutting your tongue or cheek.
Take pain relief if you need it. Paracetamol or ibuprofen, as directed on the pack. Don't hold aspirin against the gum, as it can burn the tissue.
Use a cold pack for swelling. Hold it on the outside of your face, 20 minutes on and 20 minutes off.
Chew on the other side. Skip very hot, cold or hard food until you've been seen.
Call your dentist. Most breaks are best seen within 24 to 48 hours, and sooner if there's pain or bleeding.
Why a broken-off piece is worth keeping
You'll often read that a broken tooth must go in milk and never in water. That rule is for a whole adult tooth that's been knocked out, because the living cells on its root need protecting.
A broken-off fragment is different. What matters is that it doesn't dry out. The International Association of Dental Traumatology guidelines recommend bonding the original piece back on where possible. Lab research shows a fragment that's been left to dry bonds back far less strongly than one kept moist (Operative Dentistry, 2012).
So milk, saline or plain water are all fine for a fragment. Just don't wrap it in a dry tissue.
Is a Broken Tooth an Emergency?
A broken tooth is urgent when there's pain, bleeding from inside the tooth, a pink or red dot in the middle of the break, or the tooth has moved. A small, painless chip isn't an emergency, but it should still be checked within a few days.
What you notice | How soon | Where to go |
Adult tooth knocked out completely | Straight away, ideally within 30 minutes | Dentist |
Pink or red spot in the break, or bleeding from the tooth itself | Same day | Dentist |
Severe pain, or the tooth is loose or pushed out of place | Same day | Dentist |
Sharp edge, mild sensitivity, little or no pain | Within a few days | Dentist |
Small chip with a smooth edge | Within a week or two | Dentist |
Swelling spreading towards the eye or neck, trouble swallowing or breathing, a suspected broken jaw, a head knock, or bleeding that won't stop | Now | Hospital emergency department or 000 |
That pink spot matters. It usually means the break has reached the pulp (the soft centre of the tooth that holds the nerve and blood supply), and the sooner it's covered, the better the chance of keeping the nerve healthy.
Campbelltown Hospital's emergency department can manage a jaw injury, head knock or serious swelling, but it can't repair the tooth itself. You'll still need a dentist for that part. Our emergency dentist page explains how same-day urgent appointments work at our Bradbury clinic.
Chipped, Cracked, Broken or Split: What's the Difference?
A chip takes off a small piece of enamel. Cracks are lines through the tooth that haven't separated yet. A break removes a larger piece, and a split tooth has separated into two parts.
Dentists grade the damage on a scale like this one, adapted from the American Association of Endodontists' classification of cracked teeth:
Type | What it is | Common signs | Usual fix |
Craze lines | Hairline lines in the enamel only | None, just faint lines in good light | Usually nothing |
Chipped tooth | A small piece of enamel lost, often from a front tooth edge | Rough or sharp edge, sometimes mild sensitivity | Polishing or bonding |
Fractured cusp | A corner of a back tooth breaks off, often next to a large filling | Sharp edge, food catching, often little pain | Filling, onlay or crown |
Cracked tooth | A crack from the chewing surface down towards the root, not yet separated | Sharp pain when you bite or let go, sensitivity to cold | Crown or onlay, sometimes root canal treatment |
Broken tooth | A large part of the tooth lost, sometimes exposing the nerve | Visible gap, pain, a pink spot | Crown, root canal treatment or extraction |
Split tooth | The tooth has separated into two pieces | Pieces move when you bite, gum swelling | Part of the tooth saved at best, often extraction |
Vertical root fracture | A crack starting in the root, most often in a root-filled tooth | Few symptoms, sometimes a gum bump like a pimple | Usually extraction |
The further down the table, the harder the tooth is to save. That's the main reason not to sit on a crack. Cracks can travel deeper over time, and a tooth that needed an onlay this month may need an extraction next year.
How Do You Fix a Broken Tooth?
A broken tooth is fixed by rebuilding the missing part, protecting what's left, and treating the nerve if the break has reached it. Which option suits you depends on how much tooth is gone, where it sits in your mouth, and whether the nerve is involved.
Damage | Usual repair | Visits | How long it typically lasts |
Tiny chip, smooth edge | Polishing | 1 | No material to wear out |
Small chip on a front tooth | Composite bonding or reattaching the fragment | 1 | Often 5 to 10 years with good care |
Broken corner on a back tooth | White filling | 1 | Often 7 to 10 years or more |
Large break, or a cracked back tooth | Onlay or crown | Usually 2 | Crowns commonly 10 to 15 years or more |
Break that reaches the nerve | Root canal treatment, then a crown | 2 to 3 or more | Depends on the final crown |
Split tooth, or a break well below the gum | Extraction and a replacement tooth | Several | Depends on the replacement |
Polishing and smoothing
The smallest chips sometimes need nothing more than a polish to take off the sharp edge. It takes a few minutes and usually no anaesthetic.
Reattaching the broken piece
If you kept the fragment and it's in one piece, it can often be bonded back on with dental adhesive. Nothing matches your tooth's colour and texture like your own enamel.
Composite bonding
For most small and medium chips, fixing a chipped tooth means composite bonding. Tooth-coloured resin is shaped onto the tooth and set with a curing light. It's the chipped tooth repair we do most often at Bradbury Dental Surgery, and most take under an hour. You can read how the process works on our dental bonding page.
White fillings
A broken corner on a back tooth, or a break caused by decay, is usually rebuilt with a tooth-coloured filling. It can usually be done in the same visit as the assessment.
Onlays and crowns
When a large part of the tooth is missing, or a back tooth is cracked, a filling alone won't hold it together. An onlay covers the weakened cusps. A dental crown covers the whole tooth. We compare the two in our guide to inlays, onlays and crowns.
Root canal treatment
If the break exposes the nerve, or the knock has damaged it, root canal treatment removes the injured pulp and seals the inside of the tooth. A crown usually follows to protect it.
Extraction and replacement
When a tooth has split through the root, or the break runs well below the gum, removing the tooth is often the most predictable option. The gap can then be filled with a dental implant, a bridge or a denture.
So broken tooth repair isn't one procedure. It's a ladder, and the sooner you get in to repair a broken tooth, the lower down that ladder the treatment usually stays.
Fixing a Broken Front Tooth
Fixing a broken front tooth usually means composite bonding, reattaching the original piece, or a veneer or crown for larger breaks. Front teeth are on show every time you smile, so getting the colour and shape right is most of the work.
Small chip on the biting edge: bonding, often in the same visit.
Larger break, fragment saved: the piece can often be bonded back on.
Larger break, no fragment: a composite build-up, composite veneers, a porcelain veneer or a crown.
Break with a pink spot: the nerve needs protecting first, then the tooth is rebuilt.
With teenagers, we usually lean towards bonding first. Their teeth and gums are still changing, and bonding removes little or no healthy tooth, which keeps more options open for later.
One more thing. A front tooth that's been knocked hard can look fine and then turn grey weeks later, because the nerve was bruised in the injury. The dental trauma guidelines recommend a review at around 6 to 8 weeks and again at 12 months, even after a small chip has been repaired.
How Are Cracked and Split Teeth Repaired?
Cracked tooth repair aims to hold the tooth together so the crack can't spread, usually with an onlay or a crown. Split tooth repair is harder. Once a tooth has separated into two pieces, it often can't be saved whole.
Cracked teeth
The classic sign is a sharp jab of pain when you bite on something, or when you let go. Cold drinks can sting too. Between those moments, the tooth often feels perfectly normal.
So how do you fix a cracked tooth? A dentist covers it with an onlay or crown, which acts like a splint and stops the two sides flexing apart every time you chew. If the crack has already inflamed the nerve, root canal treatment comes first. Our guide to how long dental crowns last covers what to expect afterwards.
The cracked teeth we see most at our Bradbury clinic are lower back molars in adults aged 40 to 60. Most have a large old silver filling, and a lot of them belong to people who clench or grind at night.
Split teeth
A split tooth has broken into two separate pieces, and you can usually feel them move when you bite. Sometimes the smaller piece can be removed and the rest kept with root canal treatment and a crown. More often, the split runs too deep and extraction is the more reliable option.
My Broken Tooth Doesn't Hurt. Can I Leave It?
No. A broken tooth with no pain still needs checking, usually within a week or two. No pain can mean the break stopped in the enamel, but it can also mean the nerve inside is already dying.
Here's what can happen when a painless break is left alone:
Decay gets in faster. The layer under the enamel (dentine) is softer and decays more quickly once it's exposed. Our guide to the signs of tooth decay shows what to watch for.
Sharp edges cause ulcers. A jagged edge rubbing the same spot on your tongue or cheek can keep a mouth ulcer coming back.
Cracks spread. A small crack can work its way deeper with every meal.
Infection can build quietly. If the nerve died after the injury, bacteria can settle inside the tooth with no pain, then flare up as a dental abscess months later.
We see a common pattern at our clinic. A back tooth lost a corner months earlier and never hurt. By the time it's checked, food packing into the gap has started decay under the edge, and what could have been a simple filling now needs an onlay or crown.
Even if you've had a broken tooth for years without trouble, it's worth one X-ray to see what's going on underneath.
Can You Fix a Broken Tooth at Home?
No. Nothing you can buy rebuilds lost enamel, and a chipped tooth can't grow back. What you can do at home is protect the tooth until a dentist can repair it.
So if you're asking "how do I fix a broken tooth myself?", the real answer is: you can't, but you can stop it getting worse.
Safe in the short term:
Dental wax over a sharp edge
Temporary filling material from the chemist, for a few days only
Pain relief as directed on the pack
Soft food, chewed on the other side
Avoid:
Superglue or any household glue. It isn't safe in the mouth and can make the repair harder.
Filing the edge with a nail file. You can't see what you're removing.
Treating a DIY repair kit as the fix. These kits are designed to last days, not months.
Biting on the tooth to test it. A cracked tooth can split the rest of the way.
What If Your Child Chips a Tooth?
A chipped baby tooth often needs only smoothing, but every knock to a child's mouth should be checked. Baby teeth sit directly over the adult teeth forming underneath, and an injury can affect both.
Never put a knocked-out baby tooth back in. It can damage the adult tooth developing below, which is why the dental trauma guidelines for baby teeth advise against it.
Do put a knocked-out adult tooth back (usually from around age 6) if you can, holding it by the crown. If not, carry it in milk and come straight in.
Watch the colour. A baby tooth that turns grey or dark in the weeks after a knock needs another look.
Across Campbelltown and the Macarthur region, we see a clear rise in chipped front teeth once the winter footy and netball seasons start. The Australian Dental Association recommends a mouthguard for both games and training, including in sports people don't think of as contact sports, like cricket, basketball and soccer.
Our children's dentistry team sees young patients for injuries as well as check-ups. If your family receives an eligible government payment, the Child Dental Benefits Schedule can help with basic treatment such as fillings, root canal treatment and extractions. For children whose two-year period starts in 2026, the cap is $1,158 (ADA). Cosmetic work isn't covered.
How Can You Stop a Tooth Chipping Again?
Most chipped teeth come from three things: impact, grinding, and biting something harder than enamel. A few habits cover all three.
Wear a custom mouthguard for sport. A custom-fitted mouthguard spreads the force of a hit across the whole arch.
Deal with grinding. Night-time grinding wears and cracks teeth slowly. An occlusal splint protects them while you sleep, and our guide to managing teeth grinding covers the daytime side.
Don't chew ice, hard lollies or popcorn kernels. And stop using your teeth to open packets and bottles.
Get large old fillings checked. A back tooth with a big filling can lose a cusp eating something soft. An onlay placed before it breaks is a smaller job than one placed after.
Keep up regular check-ups. Small cracks and worn fillings are easier to catch early. See how often you should visit the dentist.
Getting a Chipped or Broken Tooth Checked
A chipped or broken tooth is easier to repair the sooner it's seen. At your visit, we'll check how deep the break goes with an X-ray and a close look at the nerve, then explain your repair options before anything starts.
If the break is painful, bleeding or showing a pink spot, read about our same-day emergency dental care in Campbelltown. For a cosmetic chip on a front tooth, our page on dental bonding at Bradbury Dental Surgery explains how it's done.
We see patients from Bradbury, Campbelltown, Camden, Narellan, Leumeah and across the Macarthur region. Afterpay, Zip and payment plans are available, and we accept DVA and OHFFSS.

Frequently Asked Questions
Can a chipped tooth heal or grow back on its own?
No. Enamel has no living cells, so a chipped tooth can't grow back or repair itself. Small chips can be smoothed, and larger ones need bonding or a filling to replace what's been lost.
How long can I leave a broken tooth before seeing a dentist?
If it hurts, bleeds, or shows a pink spot, see a dentist the same day. A painless chip can wait a few days, but leaving any broken tooth for weeks raises the chance of decay, a spreading crack, or a bigger repair.
Does a broken tooth always need a root canal?
No. Root canal treatment is only needed when the break reaches the nerve or the injury has damaged it. Most chips and small breaks are repaired with bonding, a filling or an onlay.
Will my health fund cover a broken tooth repair?
Medicare doesn't cover general dental care for most adults. Private extras cover usually pays part of fillings and crowns, depending on your policy and waiting periods. Eligible children may be covered by the CDBS, and DVA and OHFFSS can apply to eligible patients.
Can a tooth broken at the gum line be saved?
Sometimes. If enough healthy root remains, the tooth can often be kept with root canal treatment, a post and a crown, occasionally after a minor gum procedure. If the break runs well below the gum or splits the root, extraction and a replacement tooth is usually the more reliable option.
