What Causes a Fractured Tooth and How Can It Be Fixed?

By Gila Ridge Dental | August 3, 2026

A fractured tooth does not always hurt right away, and that is exactly what makes it easy to ignore until the damage has already gone deeper.

Most people assume a broken tooth is obvious. But many fractures start small, invisible to the eye, quietly growing until chewing on the wrong side or sipping something cold suddenly sends a sharp jolt through your jaw.

At Gila Ridge Dental, we see this more often than you might think. As your trusted dental care provider in Yuma, we have had patients come in after months of brushing off that occasional twinge, not realizing a crack has been quietly working its way through their tooth the entire time. The earlier we catch it, the simpler the fix and the better the outcome for your smile. 

If you have been feeling unexplained tooth sensitivity or discomfort that seems to come and go, do not wait. Call our team at 928-249-3673 to schedule an exam. We will take a close look and tell you exactly what is going on.

Why Do Teeth Fracture in the First Place?

Teeth are remarkably strong, but they are not unbreakable.

Several everyday habits and situations put your teeth under more stress than they are built to handle. Over time, that pressure adds up.

Some of the most common causes we see include:

  • Biting down on hard foods like ice, hard candy, popcorn kernels, or crusty bread
  • Teeth grinding and clenching (bruxism), which many people do at night without realizing it
  • Trauma or injury: a fall, a sports collision, or even an unexpected knock to the face
  • Large old fillings that weaken the remaining natural tooth structure around them
  • Sudden temperature changes, such as eating something very hot followed immediately by something ice cold
  • Age: teeth naturally become more brittle over time, even with excellent oral hygiene

Sometimes there is no single dramatic moment. A tooth can fracture gradually from repeated stress over months or years. That is why it can feel like the problem appeared out of nowhere, even though it was building the whole time quietly.

Not All Tooth Fractures Are the Same

This is something we explain to patients regularly, because the type of fracture makes a big difference in how we treat it.

  • Craze lines are tiny, shallow cracks in the outer enamel. They are usually cosmetic and do not cause pain or require treatment beyond monitoring.
  • A cracked tooth is a fracture that runs from the biting surface downward, sometimes toward the root. This is one of the most common types we treat, and it can range from minor to serious depending on how deep it goes.
  • A fractured cusp happens when a piece of the tooth’s chewing surface breaks off. This often occurs around an existing filling. It can be uncomfortable but usually does not affect the nerve.
  • A split tooth is a crack that has progressed so far it has divided the tooth into distinct segments. This is a more advanced situation that requires prompt care.
  • A vertical root fracture starts at the root and travels upward. These are tricky because they often produce few symptoms early on and are sometimes only discovered during treatment for another issue.

Knowing which type you are dealing with is the first step to knowing what to do about it.

Signs That Your Tooth May Be Fractured

Here is where things get tricky. A fractured tooth does not always announce itself loudly.

Many of our patients describe symptoms that sound something like this:

  • Pain when biting down that disappears almost immediately after
  • Sensitivity to hot, cold, or sweet foods and drinks that lingers longer than it should
  • Discomfort that comes and goes and is difficult to pinpoint to one specific tooth
  • A sharp edge you can feel with your tongue but cannot see
  • No pain at all, just a visible chip or crack noticed by accident

The intermittent nature of the pain is one of the main reasons people delay coming in. It goes away, so they assume it resolved on its own. But a crack does not heal the way soft tissue does. It does not close back up. Without treatment, it typically gets worse.

If any of these signs feel familiar, that is your cue to get it checked.

How We Find and Diagnose a Fractured Tooth?

Diagnosing a cracked tooth takes more than a quick look. Some fractures are microscopic and will not show up on a standard X-ray.

When a patient comes into our Central Yuma dental office with symptoms that suggest a possible fracture, here is what the diagnostic process typically looks like:

  • Visual exam under magnification and bright lighting to spot cracks on the tooth surface
  • Dental X-rays to check for fractures near the root or signs of bone involvement
  • Bite test: we ask you to bite down on a small instrument to help isolate which tooth and which part of the tooth is causing pain
  • Dental dye applied to the tooth surface to make hairline cracks more visible
  • Probing along the gum line to check for vertical root fractures

This combination gives us a clear picture of what we are working with before we recommend anything. We do not guess; we look for evidence, and then we walk you through exactly what we found.

How a Fractured Tooth Is Treated

Treatment depends entirely on the type of fracture, how deep it goes, and whether the nerve has been affected.

  • Dental bonding or a tooth-colored filling works well for minor chips and surface-level fractures. At our Central Yuma dental office, our dentist removes any rough or damaged material, smooths the area, and applies a bonding resin that blends naturally with your tooth. It is a straightforward procedure that usually takes a single visit.
  • A dental crown is the most common treatment for a cracked tooth that is still structurally intact. The crown fits over the entire visible portion of the tooth, holding it together and protecting it from further damage. Most patients are surprised by how comfortable and natural a well-fitted crown feels.
  • A root canal becomes necessary when the fracture has reached the inner pulp of the tooth, the soft tissue that contains nerves and blood vessels. If you are experiencing significant pain or the tooth has become infected, this is likely the path forward. After the root canal, a crown is placed to protect and restore the tooth.
  • Tooth extraction is a last resort, used only when the fracture is so severe that the tooth cannot be saved. If this is the case, we discuss your options for replacing the tooth, most commonly a dental implant or a fixed bridge, so your bite, function, and appearance are all restored.

Whatever route your treatment takes, the goal is always the same: save as much of the natural tooth as possible and make sure you leave our office with a tooth that works and feels right.

Can You Prevent a Fractured Tooth?

Not every fracture is preventable, but there is quite a bit you can do to lower your risk.

  • Wear a nightguard if you grind your teeth: Bruxism puts enormous pressure on your teeth night after night, and a custom-fitted nightguard is one of the most effective ways to protect them.
  • Be mindful of what you chew: Ice, hard candy, and unpopped popcorn kernels are among the most common culprits behind cracked teeth. It is not worth the risk.
  • Do not use your teeth as tools: Opening packages, tearing tags, cracking nuts these habits put stress on your teeth in ways they are not designed to handle.
  • Keep up with routine dental visits:  A dentist who sees you regularly can spot early craze lines, weakening enamel, or old restorations that may be putting a tooth at risk long before a fracture becomes a problem that needs treatment.
  • Get old fillings evaluated: Large silver fillings from years ago can expand and contract with temperature changes over time, creating pressure that eventually leads to cracks in the surrounding tooth.

Prevention is always easier and less expensive than treatment. That is the honest truth.
