A fractured tooth—commonly referred to as a cracked tooth—occurs when a crack develops in the structure of a tooth. This crack may be superficial, or it may extend from the biting surface down toward the root. In more severe cases, a fracture can result in a tooth splitting or breaking apart.

While some fractures may be minor and not pose an immediate threat to your oral health, others can lead to infection, nerve damage, or tooth loss if left untreated. That’s why it’s important to have any signs of a crack evaluated promptly by a dental professional.

At Westmount Dental, we specialise in diagnosing and treating fractured teeth using advanced diagnostic tools and restorative treatments. Our goal is always to preserve as much of the natural tooth as possible and restore its strength and function.

What causes a fractured tooth?

Teeth are hardy, but they’re not invincible. Tooth grinding, injuries and amalgam fillings that have been contracted can all cause minor, moderate and major fractures. Tooth fractures tend to be more common in children and older people.

Back teeth, such as molars, are most susceptible to fractures as they do most of the hard work of chewing down foods of all textures, shapes, and sizes. These teeth also suffer the most when you grind your teeth.

What Causes a Fractured Tooth?

Although teeth are designed to withstand the forces of everyday biting and chewing, they are still vulnerable to damage over time. Several factors may lead to a tooth fracture, including:

• • Tooth Grinding (Bruxism)

Chronic clenching or grinding of the teeth places repeated stress on tooth enamel and underlying structures. Over time, this pressure can lead to hairline cracks or more serious fractures—particularly in the back teeth.

• • Physical Trauma

A sudden impact or injury, such as a fall, sports injury, or car accident, can fracture a tooth. Even biting down on something hard, like an unpopped popcorn kernel or ice, can lead to a crack.

• • Large Fillings

Amalgam or composite fillings that are large or have deteriorated over time can weaken the surrounding tooth structure, making it more susceptible to fracture.

• • Large Fillings

Amalgam or composite fillings that are large or have deteriorated over time can weaken the surrounding tooth structure, making it more susceptible to fracture.

• • Age

Fractured teeth are more common in both older adults and children. In older patients, natural wear and tear from years of chewing can thin the enamel, while in children, developing teeth may be more vulnerable to trauma and grinding.

Which Teeth Are Most Affected?

Molars—especially the first and second molars—tend to be the most commonly fractured teeth. These are your strongest teeth, but they bear the brunt of chewing forces and are especially prone to stress from grinding and clenching.

Types of Dental Fractures

Not all dental fractures are the same. The type of crack will determine how we treat the tooth and whether it can be saved:

• • Tooth Grinding (Bruxism)

Chronic clenching or grinding of the teeth places repeated stress on tooth enamel and underlying structures. Over time, this pressure can lead to hairline cracks or more serious fractures—particularly in the back teeth.

• • Craze Lines

These are superficial cracks that affect only the outer layer of enamel. Craze lines are very common, particularly in adults, and typically don’t require treatment unless they worsen or affect aesthetics.

• • Cracked Tooth

This type of crack extends from the chewing surface toward the root of the tooth. Without prompt intervention, a cracked tooth can progress to a split tooth. Restorative treatment such as a crown is often necessary to protect the tooth and prevent further damage.

• • Split Tooth

A split tooth results from an untreated crack that has progressed over time, causing the tooth to divide into segments. In these cases, root canal therapy followed by a crown may be recommended, though extraction may be necessary if the damage is extensive.

• • Vertical Root Fracture

These fractures begin in the root and extend toward the chewing surface. They are often less noticeable until infection or swelling develops. In many cases, extraction is required, though advanced treatments may offer other solutions.

Why Treat a Cracked Tooth Promptly?

Even if a fractured tooth isn’t causing pain, delaying treatment can lead to more severe complications. Bacteria can enter the crack and infect the inner pulp of the tooth, resulting in the need for root canal therapy or extraction.

Prompt diagnosis and treatment can often preserve the tooth and avoid the need for more invasive procedures.
