Have you ever felt a sudden sharp pain when biting into your favorite snack? Or maybe you’ve felt persistent discomfort or sensitivity in a tooth that doesn’t seem to fade away? These are common signs of a cracked tooth, a dental problem many of us encounter at some stage.

Keep on reading to understand why cracked teeth occur, how to recognize them, what treatments are available, and how to prevent them from leading to more serious issues.

What is a Cracked Tooth?

A cracked tooth is a dental condition characterized by a fracture or crack in the tooth structure. These cracks vary in severity, ranging from minor ones that impact only the enamel to more severe fractures that extend deep into the tooth’s root.

What are the Causes of Cracked Teeth?

Cracked teeth can result from various factors and situations, including:

  • Chewing on hard items like hard candies, ice, or bones.
  • Accidental trauma or injury to the face or mouth, such as falls or blows.
  • Tooth decay weakens the tooth’s structure, increasing the likelihood of developing cracks.
  • Large fillings can weaken the integrity of the tooth over time.
  • Bruxism (teeth grinding) and clenching, especially during sleep, can exert excessive pressure on the teeth.
  • Fluctuations in mouth temperature, such as consuming hot foods followed by cold drinks, cause gradual expansion and contraction of tooth material.
  • Age-related wear and tear on teeth can make them more susceptible to cracking over time.

What are the Common Symptoms of a Cracked Tooth?

Recognizing the symptoms of a cracked tooth can help you seek timely dental care. Common signs and symptoms include:

  • Sensitivity: Feeling sensitivity to hot, cold, or sweet foods and drinks, especially when the stimulus is removed.
  • Pain when Chewing: Experiencing discomfort or sharp pain when biting or chewing, particularly with pressure on the cracked tooth.
  • Intermittent Discomfort: Having occasional pain or discomfort that comes and goes, making it more challenging to pinpoint the problematic tooth.
  • Gum Swelling: Observing swelling or tenderness in the gums around the affected tooth can indicate inflammation or infection in more severe cases.

What is the Diagnosis of a Cracked Tooth? 

Diagnosing a cracked tooth involves a thorough dental examination performed by a dentist. The diagnostic process typically includes:

  1. Visual Inspection: The dentist visually inspects the teeth using a dental mirror and light to identify any visible signs of cracks or damage on the tooth surface.
  2. Dental X-rays: X-rays are commonly used to detect cracks or fractures that are difficult to see through the naked eye, especially those affecting deeper layers of the tooth or extending below the gum line.
  3. Specialized Tests: Specific tests are conducted to assess the tooth’s response to hot, cold, or pressure stimuli. These tests tell the location and severity of the crack.
  4. Bite Tests: Bite tests involve biting on different objects or applying pressure to specific areas to replicate the pain or discomfort associated with the cracked tooth. This aids in confirming the diagnosis and planning appropriate treatment strategies.

By utilizing these diagnostic techniques, dentists can accurately diagnose cracked teeth, determine the extent of the damage, and recommend suitable treatment options to restore dental health and functionality.

What are the Types of Tooth Cracks? 

Tooth cracks vary in severity and location within the tooth structure. Let’s take a closer look at the common types of tooth cracks:

Craze Lines 

These are minor cracks limited to the enamel, the outer layer of the tooth. Craze lines are mostly cosmetic and typically don’t cause pain or need treatment.

Fractured Cusp 

This happens when a part of the tooth’s chewing surface (called the cusp) breaks off. Fractured cusps can lead to sensitivity and discomfort, especially during chewing.

Cracked Tooth 

A vertical crack starts from the tooth’s biting surface and extends towards its root. Cracked teeth may cause occasional pain or sensitivity, with severity depending on the crack’s depth.

Split Tooth 

This represents a severe tooth crack where the tooth splits into distinct parts, often causing significant pain and requiring immediate dental attention.

Vertical Root Fracture 

A crack that begins in the tooth’s root and extends upward toward the chewing surface. Vertical root fractures are hard to detect without X-rays and usually require professional diagnosis.

Treatment Options for Cracked Teeth 

Treating a cracked tooth depends on various factors, such as the type and severity of the crack, its location, and your overall dental health. Here are common treatment options:

Dental Bonding: 

Minor cracks or craze lines limited to the enamel may be addressed with dental bonding. This procedure applies a tooth-colored resin to the cracked area, restoring appearance and guarding against further damage.

Dental Crown:

For more extensive cracks compromising the tooth’s structure, a dental crown is often recommended. This crown covers and reinforces the visible part of your tooth above the gum line, restoring both function and strength.

Root Canal Therapy: 

A root canal becomes necessary when a crack extends into the tooth’s pulp, causing pain, infection, or sensitivity. This procedure removes the damaged pulp, disinfects the tooth, and seals it to prevent future issues.

Tooth Extraction: 

Extraction may be required in severe cases where the crack is extensive or if the tooth cannot be saved with other treatments. After tooth extraction, replacement options such as dental implants, bridges, or removable dentures can restore dental function and aesthetics.

Nightguard for Bruxism: 

If teeth grinding (bruxism) contributed to the cracked tooth, wearing a custom nightguard as prescribed by your dentist can prevent further damage by cushioning the teeth and reducing grinding forces while you sleep.

Preventive Measures 

While certain causes of cracked teeth are inevitable, you can adopt the following precautions to minimize the risk:

Avoid chewing on hard objects such as ice, pens, or hard candies.

Use a mouthguard during sports activities to shield your teeth from potential trauma.

Follow good oral hygiene practices to prevent tooth decay and maintain the strength of your teeth.

If you experience bruxism (teeth grinding), consult your dentist about a custom nightguard to mitigate its effects.


Dealing with a cracked tooth involves more than just discomfort—it poses a real threat to your dental well-being if left untreated. Early identification and proper treatment can often preserve the tooth and prevent further complications. If you notice any signs of a cracked tooth, don’t delay scheduling a dental appointment for a thorough evaluation and personalized treatment plan.

How can I prevent cracked teeth? 

Preventive measures include avoiding chewing on hard objects, wearing a mouthguard during sports activities, maintaining good oral hygiene to prevent decay, and addressing teeth grinding (bruxism) with a custom nightguard.

When should I seek dental care for a suspected cracked tooth? 

It’s essential to schedule a dental appointment if you experience any symptoms of a cracked tooth, such as pain, sensitivity, or discomfort when eating. Early diagnosis and treatment can prevent complications and preserve dental health.

Does a cracked tooth always cause pain? 

Not necessarily. Some cracked teeth may only show sensitivity or occasional discomfort without consistent pain, emphasizing the importance of early diagnosis.
