Our teeth are incredibly strong, designed to handle the pressure of biting and chewing tough foods. But even though they are durable, they’re not indestructible. Accidents, wear and tear, and even poor dental habits can all lead to cracked teeth.

In fact, according to the ADA Health Policy Institute’s latest data, 71% of dentists surveyed reported a 63% increase in the prevalence of cracked teeth over the past year.

Understanding how cracks happen and recognizing the signs early can help you avoid more serious issues down the road.

What Causes Cracked Teeth?

Several factors can lead to cracked teeth. Some are a result of sudden, sharp force, while others are caused by gradual wear.

Here are the most common causes:

Blows to the Mouth:

A sharp impact, like a sports injury or accident, can crack a tooth.

Chronic Teeth Grinding (Bruxism):

Habitual grinding wears down the enamel, increasing the risk of cracks.

Tooth Decay:

Decay weakens the tooth, making it more prone to cracking.

Large Fillings or Root Canal Treatments:

These procedures may compromise the tooth’s structure, making it more vulnerable to damage.

Hard Foods:

Biting down on hard foods like nuts, ice, or candy can crack a tooth.

Temperature Changes:

Extreme shifts in temperature (e.g., hot food followed by cold drinks) can cause the tooth to expand or contract, leading to cracks.

Age:

As we age, our teeth become weaker, and the risk of cracking increases—especially after 50.

Weakened Teeth:

Enamel erosion, genetics, and previous dental work can all weaken teeth, making them more prone to cracks.

Recognizing the Signs of a Cracked Tooth

Cracked teeth aren’t always easy to spot, especially when the fracture is small.

However, certain signs can indicate that a tooth may be cracked. Keep an eye out for:

Pain when chewing or biting down:

This could indicate pressure on the crack.

Increased tooth sensitivity:

You may feel discomfort when exposed to hot or cold temperatures.

Persistent pain:

If the pain doesn’t go away or worsens, it may be a sign of a cracked tooth.

Swelling of the gums:

This could be an indication of irritation around the cracked tooth.

Bad breath:

In some cases, a crack can lead to infection, which may cause foul-smelling breath.

When you experience these symptoms, it’s essential to get your tooth checked out by a dentist. Ignoring the issue could lead to more severe damage and infection.

Types of Cracked Teeth

Cracked teeth come in various forms, from minor hairline fractures to more serious splits. The damage can extend through the enamel, into the dentin, or even to the pulp. Here are the most common types:

Craze Lines:

These are fine, shallow cracks in the enamel. They don’t usually require treatment since they don’t affect the tooth’s function.

Fractured Cusp:

A deeper crack that can extend into the dentin, often caused by a large filling compromising the tooth.

Vertical Cracks:

These cracks can reach the gumline and cause significant discomfort.

Split Tooth:

A crack that extends below the gumline may cause a portion of the tooth to break off. In this case, the tooth may not be salvageable.

If a tooth is severely cracked, it may need to be extracted to prevent infection or further damage.

Trauma from an accident or injury can also lead to multiple cracked teeth, requiring immediate dental care.

Risks of Delaying Treatment

Failing to address a cracked tooth can lead to several complications, including:

Abscess around the tooth
Infection spreading to the gums or jawbone
Fever and swelling
Tenderness around the neck and face

This is why it’s so important to see a dentist as soon as you notice any signs of a cracked tooth.

How Are Cracked Teeth Treated?

When you visit your dentist with a cracked tooth, they will first examine the tooth and may use a magnifying device or an explorer tool to identify the crack. X-rays can help determine how deep the crack extends.

The treatment will depend on the type and severity of the crack. Here are some common treatment options:

Bonding:

This is often used for smaller cracks. Your dentist will apply a tooth-colored resin to seal the crack and restore the tooth’s strength.

Veneers:

For cracks affecting the appearance of your tooth, veneers can cover the crack, improving the look of your smile.

Dental Crowns:

A crown may be placed over the damaged tooth to protect it and restore its function. Both traditional and same-day crowns can be used for this.

Root Canal:

If the crack extends to the pulp, a root canal is needed to remove the infected tissue. Afterward, a crown will be placed to protect the tooth.

Tooth Extraction:

If the crack is too severe to repair, the tooth may need to be extracted. Your dentist will then discuss options like dental implants or bridges to restore your smile.
