When it comes to maintaining impeccable oral health, promptly addressing issues like a cracked tooth is crucial. Many often ponder, “Does a cracked tooth need to be pulled?” The truth is not all cracks necessarily lead to tooth extraction. Factors such as the severity of the crack, its location, and its impact on the tooth’s structure play a significant role in the decision-making process.

Cracked teeth can range from tiny craze lines on the tooth enamel, barely visible to the naked eye, to extensive cracks that reach the gum line, potentially jeopardising the natural tooth. Chipped teeth, on the other hand, might be a result of biting hard objects or due to trauma, leading to sharp pain or sensitivity to hot and cold temperatures. Vertical root fractures or a fractured cusp, which affects the tooth’s chewing surface, might even go unnoticed until the bone or gum surrounding the tooth becomes infected.

Certain cracks, especially those on the tooth’s structure that extend beneath the gum line, could demand a more intensive treatment approach, such as a root canal or dental crown placement. However, not all cracks require such drastic measures. Sometimes, early treatment and preventive measures can save teeth from severe damage. This could be as simple as avoiding ice cubes or using a protective mask when playing contact sports.

A split tooth, resulting from unchecked vertical cracks or a severely decayed or damaged tooth, might lead to excruciating pain and eventual tooth loss. However, seeking treatment early and consulting a dentist can pave the way for varied treatment options, depending on the crack’s location, how deep it extends, and its impact on the tooth’s pulp tissue.

Understanding Tooth Cracks



Tooth cracks are more common than we think, and they come in various types, each with its own set of implications. Let’s delve into the distinct categories of cracks and understand their common causes.

Types of tooth cracks

Craze lines

These are tiny cracks primarily found on the tooth enamel. Often superficial, they might not affect the tooth’s structure but can potentially lead to more extensive cracks if left untreated.

Fractured cusp

This type of crack usually occurs around a dental filling, especially if the filling is large. A fractured cusp affects the chewing surface of the tooth and can lead to a chipped tooth or further damage if not addressed.

Cracks that extend to the gum line

These cracks go beyond the enamel and can even reach the tooth’s pulp. If a crack extends deeply, it might cause excruciating pain and require root canal treatment or even tooth extraction if the damage is too severe.

Split tooth

As the name suggests, this is when a tooth has split vertically into two distinct segments, often due to untreated vertical cracks. This can lead to tooth loss if treated promptly.

These are cracks that begin in the root and extend upward. They might not show symptoms initially but can cause infections or gum disease around the affected tooth if not diagnosed early.

Causes of tooth cracks

Biting on hard substances

Chewing or biting down on hard objects like ice cubes or candies can lead to tooth cracks. This action can cause immediate trauma to the tooth, leading to sharp pain and a fractured tooth.


Any direct impact from playing contact sports without a protective mask or a fall can lead to dental injury, including cracked or chipped teeth.

Grinding or clenching

Persistent teeth grinding can weaken the tooth’s structure over time, increasing the risk of extensive cracks or even a split tooth.

Large fillings

Fillings, especially large ones, can sometimes weaken the integrity of the surrounding tooth enamel. This weakened area might become prone to fractures, particularly when subjected to biting pressure.

Extreme temperature changes

Constant exposure to hot and cold temperatures, like sipping hot coffee followed by cold water, can cause tooth enamel to expand and contract. Over time, this can result in tiny cracks, which might expand if preventive measures are not taken.

Symptoms of a Cracked Tooth

A cracked tooth might not always be evident at first glance, and it’s not uncommon for people to remain unaware of the damage until they experience distinct symptoms. Recognising these early signs can save a tooth from further damage and be the difference between a simple repair and a more invasive procedure. Here’s a breakdown of the common symptoms:

Pain when chewing or biting

One of the most telling signs of a cracked tooth is pain or discomfort when applying pressure, such as biting or chewing. This is because the act can cause the cracked segments of the tooth to move, aggravating the tooth’s pulp where the nerve endings are located.

Sensitivity to hot or cold

A cracked tooth can expose the inner layers of the tooth, including the dentin and, in some cases, the pulp. This exposure can make the tooth particularly sensitive to hot and cold temperatures. For example, someone with a crack might experience sharp pain when consuming hot coffee or ice cream.

Swelling in the gum area around the affected tooth

If a cracked tooth goes untreated, it can lead to infections. This infection might present as swelling in the gum surrounding the damaged tooth. Over time, if left untreated, it could even progress to more serious dental conditions, including abscesses.

Discomfort that comes and goes

Unlike a constant toothache that might indicate other dental problems, the pain or discomfort from a cracked tooth can be sporadic. This means it might come and go, often misleading individuals to dismiss it. However, this intermittent pain can clearly indicate a crack, especially if specific actions or temperatures trigger it.

Treatment Options

The course of treatment for a cracked tooth hinges on the type, location, and severity of the crack. It’s vital to remember that timely intervention can prevent the escalation of problems and can also save a tooth from extraction. Below is an overview of potential treatment options, each tailored to specific crack scenarios:


Sometimes, especially in the case of minor craze lines, the dentist might recommend simple observation. Not all cracks need immediate intervention. Often, with proper oral care, these minor cracks don’t progress, and patients can continue without invasive procedures. However, regular dental check-ups are necessary to monitor the crack and ensure it’s not expanding or causing other issues.


One of the less invasive treatments is dental bonding. A dentist uses a plastic resin to seal the crack, restoring the tooth’s appearance and function. This method is particularly effective for smaller cracks and provides a seamless fix that often matches the natural tooth’s shade.


A dental crown might be the ideal solution for cracks that are more significant but haven’t yet jeopardised the tooth’s pulp. A crown is a prosthetic cap placed over the tooth, offering protection and restoring its shape. This is particularly common in cases with a risk of the crack expanding or when a significant part of the tooth’s structure has been compromised.

Root Canal

A root canal treatment might be necessary if the crack has extended deep into the tooth, reaching the pulp. During a root canal, the damaged or infected pulp is removed, and the inside of the tooth is cleaned, disinfected, and sealed. This process can save the natural tooth and prevent further infections or complications.

Extraction might be the only viable option in extreme cases where the crack is too severe or the tooth is split. This is typically the last resort when other treatment methods can’t salvage the natural tooth. After extraction, several ways exist to replace the missing tooth, such as dental implants or bridges, ensuring that patients can still maintain a full and functional smile.

Factors Influencing the Decision to Pull a Cracked Tooth

The decision to extract a tooth is made with seriousness, and numerous factors come into play before reaching that conclusion. While some cracks can be managed with minimal interventions, others can lead to the more dramatic extraction step. Here are the primary determinants that influence this decision:

The extent of the crack

Naturally, the depth and length of the crack are significant factors. Small, superficial cracks might not necessitate extraction. Still, if a crack extends deep into the tooth, reaching the pulp or passing it to the root, the damage might be too significant for other treatment methods.

Location of the Crack

Not all cracks are created equal. A crack on the crown (the visible part of the tooth) may be treated differently than one closer to or beneath the gum line. Vertical root fractures, for example, which start at the root and move upwards, are especially problematic and might necessitate extraction.

The Patient’s Overall Oral Health

If a patient already has underlying oral health issues such as gum disease or other infections, a cracked tooth can exacerbate these problems. In such situations, leaving a compromised tooth might pose a greater risk to overall dental health, leaning toward the decision for extraction.

Age and Health of the Tooth

An older tooth or one undergoing several treatments might be more vulnerable. Similarly, teeth that show signs of decay, extensive dental fillings, or previous root canal treatments might be less resilient to cracks, making extraction a more probable recommendation.

If left unchecked, some cracks can lead to severe complications like abscesses, further decay, or even loss of surrounding bone. In cases where the potential for complications is high, and other treatments might not mitigate these risks effectively, extraction might be the safer route.


Cracked teeth, in their varied forms and severities, remind us of the delicate balance between preserving our natural tooth structure and recognising when intervention is necessary.
