Cracked Teeth
Cracked Teeth is available at these locations:
Few problems are as hard to track down as a cracked tooth. The pain tends to come and go, and the crack often hides from the naked eye. That is where advanced imaging and magnification come in: at Aesthetic Dentistry, our doctors use them to detect cracked teeth and pinpoint exactly where the fracture sits and how serious it is. Treating it early is what saves the tooth and stops the crack from spreading.
What it is
A fracture in a tooth, anywhere from a harmless surface crack to a deep split reaching into the root. Some appear suddenly after trauma; others build slowly over years of grinding and wear.
Who it's for
Anyone with on-and-off pain when chewing, temperature sensitivity, or unexplained discomfort in a tooth, particularly the back teeth, where cracks turn up most often.
How we help
We locate the crack with advanced diagnostics, magnification, transillumination, and digital imaging, then treat it in a targeted way to save the tooth wherever possible.
A cracked tooth never heals on its own and can worsen fast. Call us for an evaluation before the crack spreads.
How to Tell If Your Tooth Is Cracked
- A sharp jab when you bite down that vanishes the moment you let go
- Pain that comes and goes with no clear pattern
- Sensitivity to hot, cold, or sweet foods and drinks
- Discomfort as you eat, though you cannot tell which tooth it is
- Swelling in the gum beside the affected tooth
- Cracks turn up most in the back teeth (molars and premolars)
Common Causes
- Teeth grinding (bruxism): Years of clenching and grinding wear the enamel down
- Biting hard objects: Ice, unpopped popcorn kernels, hard candy, and pens
- Large fillings: An extensively filled tooth has less structure left and cracks more easily
- Trauma: A fall, a sports injury, or an accident
- Temperature extremes: Hot food chased straight away by an ice-cold drink
- Age: Teeth grow more brittle over time, and cracks are most common after age 50
Types of Cracks
Fractured Cusp
Here a portion of the tooth's cusp splits or breaks away completely. Because a fractured cusp rarely reaches the root, a full crown is usually enough to repair the damage. If the broken piece is still attached, our doctors may remove it first.
Cracked Tooth
A cracked tooth is an incomplete fracture running through the chewing surface, sometimes reaching down to the gum line or even the root. Catching this kind of crack early is what prevents further damage. How it is treated depends on how far the crack goes, but restoring the tooth often calls for a root canal procedure.
Split Tooth
Leave a cracked tooth alone and it can advance into a split tooth, a complete fracture running from the crown all the way through the root. At that point the dentin has separated into two distinct sections. This usually develops out of a cracked tooth over time, and if the fracture is severe enough the tooth has to be extracted.
Vertical Root Fracture
This fracture begins down at the root and works its way up toward the crown. Symptoms usually stay quiet until it becomes severe. Extraction is often the outcome, though in some cases endodontic surgery can save part of the tooth.
Treatment Options
How We Treat Cracked Teeth
- Crown: On fractured cusps and minor cracks, it binds the tooth together and keeps the crack from spreading
- Root canal + crown: Once a crack reaches the pulp (nerve), root canal therapy clears the damaged tissue and a crown follows
- Bonding: Suits minor surface cracks (craze lines) that are cosmetic rather than structural
- Extraction: Called for when the tooth is split below the gum line or the crack runs deep through the root
- Endodontic surgery: In select cases, part of a vertically fractured root can still be saved
How to Prevent Cracked Teeth
- Keep hard objects like ice, unpopped popcorn kernels, pens, and hard candy out of your bite
- If you grind or clench overnight, ask our doctors about a night guard
- Put in a mouthguard for contact sports
- Resist using your teeth as tools to open packages or tear tape
- Have large, old fillings checked, since a crown may need to replace them for added protection
Today's small crack is tomorrow's big problem. Treating it early is the surest way to save your tooth.
What to Expect at Your Visit
Visit Steps
- Symptom review: our doctors ask where the pain is, what triggers it, and how it comes and goes
- Clinical exam: Bite tests, percussion, and transillumination (a bright light shone through the tooth) help locate the crack
- Imaging: Digital X-rays, and possibly CBCT (3D) imaging, gauge the depth and direction of the fracture
- Diagnosis: our doctors identify which type of crack it is and explain the best treatment option
- Treatment: Plenty of cracked teeth can be handled the same day, and the sooner you are seen, the better the outcome
Helpful Tips
- Note which side hurts if you can, but do not worry if you cannot pin down the exact tooth
- Steer clear of chewing on the painful side until your visit
- Over-the-counter pain medication can take the edge off the discomfort
- Craze lines, the tiny surface cracks you can see on front teeth, are very common and rarely need treatment
- The sooner a crack is found, the more treatment options you have, so do not wait for the pain to grow
Frequently Asked Questions
No. Unlike a broken bone, a tooth has no blood supply in its hard outer layers, so it cannot regenerate or knit a crack back together. A cracked tooth will not heal on its own, and the everyday forces of chewing tend to work the crack open a little further over time.
That is why a small crack left alone can eventually deepen, reach the nerve, or split the tooth in two and lead to extraction. Early diagnosis and treatment matter so much precisely because the window when a cracked tooth can still be saved is widest at the beginning, before the fracture spreads.
It comes down to how a crack behaves under pressure. Biting down flexes the tooth and nudges the crack open, which irritates the pulp (the nerve) inside the tooth; the moment you release the bite, the crack closes again and the sharp pain stops. That brief, stabbing pain on release is one of the most telltale signs of a cracked tooth.
Temperature sensitivity creeps in for a related reason: the crack gives hot and cold a path to reach the nerve more easily than solid enamel would. Because the pain comes and goes rather than staying constant, a cracked tooth is easy to ignore, but that on-and-off pattern is exactly the signal worth getting checked before the crack deepens.
Often, yes, and it depends on the type of crack and how far it travels. A cracked tooth caught early, while the fracture is limited to the crown, has the best odds. Fractured cusps and many cracked teeth come back nicely with a crown, or with root canal therapy followed by a crown when the crack has reached the nerve.
The deeper a crack runs, the harder the tooth is to save: split teeth and some vertical root fractures that extend below the gum line may need extraction, sometimes followed by an implant or bridge to replace the tooth. To find out where your tooth stands, our doctors will assess your specific situation, often with an X-ray, and talk through every option honestly before any treatment.
Usually not. Craze lines are tiny, shallow cracks in a tooth's outer enamel only, and they do not reach the inner layers where the nerve lives. They are extremely common, especially in adults, and are almost always a purely cosmetic matter rather than a structural one.
Because they cause no pain and pose no threat to the tooth, craze lines need no treatment unless their appearance bothers you. If they do catch your eye, especially on a front tooth, veneers or bonding can mask them. It is still worth mentioning them at a checkup so our doctors can confirm a line is a harmless craze line and not the start of a deeper cracked tooth.
Back teeth, the molars and premolars, do the heavy lifting of chewing, so they absorb far greater biting forces than the front teeth do. Those forces concentrate on the cusps and grooves of the chewing surface, which is exactly where cracks tend to begin.
On top of that, back teeth are the ones most likely to carry large fillings from past decay, and a heavily filled tooth has less solid structure holding it together. Combine the heaviest forces with the most reduced structure, add a habit like grinding, and it is easy to see why a cracked tooth shows up in the back of the mouth far more often than the front.
Left untreated, the crack keeps spreading under the daily force of chewing. As it deepens, bacteria can work their way in, reach and infect the pulp, and bring on an abscess, which is a painful infection at the root that may require root canal therapy or extraction to resolve.
From there the cracked tooth may eventually split in two, and once a fracture runs below the gum line, extraction is often the only remaining choice. Replacing a lost tooth with an implant or bridge then costs more time and money than the original repair would have. Treating a cracked tooth early, while it can still be saved, always beats waiting for the problem to force your hand.
A crown is one of the most effective fixes for a cracked tooth, binding it together and keeping the crack from spreading under the pressure of chewing. By cupping the whole tooth, it takes over the job the weakened enamel can no longer do, which is why it is the go-to repair for fractured cusps and many cracked teeth.
If the crack has already reached the nerve, root canal therapy comes first to clear the damaged tissue, and a crown follows to protect and seal the tooth. To decide the right path, our doctors will determine whether a crown on its own is enough or whether root canal treatment is needed too, based on how deep the crack runs.
Tooth pain that comes and goes is worth a closer look. It could be a cracked tooth, so call us for an evaluation.
