Unfortunately, even a small tooth crack can be just as dangerous as an untreated cavity, and may even lead to tooth loss. According to statistics, 9.7% of patients aged 30 to 60 experience this issue. Additionally, teeth with fillings are more prone to cracks and chips than healthy, untreated teeth.

Dr. Boris Lipovetskiy is a cosmetic dentist that utilizes over five treatment techniques when dealing with a cracked tooth, depending on the severity of the damage.

What Is a Cracked Tooth?

A crack is an incomplete fracture of the tooth crown or root. The defect can be limited to the surface enamel layers, extend to the enamel-dentin junction, or pass through the enamel, dentin, and even all tooth structures. Acute or prolonged trauma can significantly impact dental tissues.

Cracks may occur when biting or chewing hard foods, due to injury, or from teeth grinding (bruxism) during sleep.

Symptoms of a Cracked Tooth

There are several telltale signs that indicate a cracked tooth:

Pain when consuming hot, cold, sweet, or acidic foods.

Discoloration due to trauma or nerve bleeding.

Swelling or tenderness in the surrounding gums.

Discomfort when biting or applying pressure.

Tooth misalignment, such as tilting or rotation.

Visible crack lines, either vertical or horizontal, on the enamel.

Why Even The Smallest Cracks Are Dangerous

A minor crack can gradually worsen over time. When chewing, molars and premolars endure high pressure, causing the fracture to deepen. Early treatment is essential to prevent severe damage.

What Can Cause Your Teeth to Crack?

Several factors can compromise the integrity of your teeth, including:

Trauma from impact or a fall.

Bruxism (teeth grinding), causing excessive jaw pressure.

Sudden temperature changes, such as drinking hot tea or coffee with ice cream.

Malocclusion, where certain teeth experience excessive contact.

Missing teeth, leading to an uneven distribution of bite pressure.

Chewing on hard objects or biting into tough foods.

Delayed dental prosthetics, as devitalized (nerve-removed) teeth become more fragile.

How Can You Tell That You Have a Cracked Tooth?

"Oftentimes, you’ll be able to feel the crack in your tooth with your tongue, or it’ll be visible in the mirror. You might experience:

  • Pain when biting, which disappears when pressure is released.
  • Sensitivity to hot, cold, sweet, or acidic foods.
  • Discoloration of the enamel or gum inflammation around the affected tooth.

If you notice any of these symptoms, schedule a free consultation with our cosmetic dentist to prevent further damage and restore your smile."

Types of Tooth Cracks

The American Dental Association (ADA) identifies several types of cracked tooth syndrome:

Superficial crack – affects only the enamel.

Fractured cusp – a piece of the tooth’s chewing surface breaks off.

Cracked tooth – the crack extends beyond the enamel but doesn’t fully split the tooth.

Split tooth – a severe crack that divides the tooth into distinct parts.

Vertical root fracture – a crack starting from the root, often invisible at first.

Classification of Cracks by Size and Visibility

Type I – The thinnest cracks, only visible under professional dental examination.

Type II – Wider cracks, noticeable under intraoral lighting without magnification.

Type III – The most severe cracks, visible to both the patient and the dentist with the naked eye (e.g., a tooth split in half).

What to Do If You Notice a Tooth Crack?

Stay calm! Follow these steps:

Rinse your mouth with a 0.05% chlorhexidine solution.

If there's pain, avoid chewing on the affected side and take a pain reliever.

Schedule an appointment with a dentist as soon as possible.

If the pain is severe, visit us immediately for emergency dental care—no appointment needed!

Diagnosing a Cracked Tooth

To determine the location, size, and depth of a tooth crack, the dentist will conduct a comprehensive examination, which includes:

1. Medical History Review

The dentist will ask about:

Your symptoms – when they started and what triggers discomfort.

Past injuries – any trauma or accidents that may have caused the crack.

Biting habits – chewing hard foods, ice, or other habits that strain teeth.

Previous treatments – when your last dental procedure was performed.

2. Visual Examination & Percussion Test

The dentist inspects all teeth and evaluates gum health.

Magnification tools such as loupes or a dental microscope may be used to detect microcracks.

Percussion test – gentle tapping to check for pain response.

Bite alignment check – assessing occlusion and missing teeth that may cause stress fractures.

3. Crack Detection with Special Indicators

A special staining solution is applied to the tooth.

It highlights cracks, cavities, and deposits while leaving healthy enamel unstained.

After rinsing, even the smallest cracks become visible as thin lines.

4. 3D Cone Beam CT Scan (CBCT)

A high-resolution scan captures a detailed 3D image of the tooth and root structure.

Allows millimeter-by-millimeter analysis, ensuring that no crack goes undetected.

Helps in selecting the best treatment plan by assessing the exact location and size of the crack.

Why Accurate Diagnosis Matters

A thorough examination not only confirms the presence of a crack but also helps determine why the tooth cracked in the first place. Identifying the cause is crucial to ensure that any restoration (filling, crown, or veneer) is protected from future fractures.

Treatment Methods for a Cracked Tooth

At our clinic, we use several advanced techniques to save cracked teeth. In most cases, treatment requires only 1 or 2 visits.

1. Enamel Smoothing (Minor Crack Repair)

This is the simplest treatment that doesn’t require anesthesia. It’s used for small surface cracks limited to the enamel, such as tiny fractures or microchips on the edge of front teeth. After polishing, a remineralizing gel with essential minerals is applied to strengthen the enamel.

2. Dental Filling (Composite Restoration)

If the crack extends deeper into the enamel or reaches the dentin, composite bonding is required.

Under local anesthesia, damaged tissue is removed to prevent the crack from spreading.

Layers of light-cured composite are applied and sculpted to restore the tooth’s natural shape.

The filling is polished to a natural shine for seamless integration.

3. Veneers (For Front Teeth Cracks)

For cracks in front teeth, veneers provide both protection and aesthetics.

Under local anesthesia, microcracks are removed, and the outer surface is prepared (0.5–1 mm reduction).

Impressions are taken, and custom-made ceramic or zirconia veneers are crafted in a lab.

The veneer replaces damaged enamel, ensuring a beautiful and natural look.

4. Dental Crowns (For Severely Damaged Teeth)

In cases where a tooth with an existing filling develops a crack, a crown may be necessary.

The tooth is reshaped, and an impression is taken.

A ceramic or zirconia crown is fabricated to fully cover and protect the tooth, preventing further damage.

5. Dental Implant (For Root Fractures)

If the tooth root is cracked, restorative treatments won’t work. A filling or crown cannot stabilize a fractured root, which can cause persistent pain and inflammation.

The damaged tooth must be removed.

A titanium implant is placed to replace the root.

A custom-made crown is attached, restoring both function and aesthetics.

Important! Don’t Delay Treatment

If you notice a crack, schedule a consultation immediately. Delaying treatment can worsen the crack, increasing the risk of tooth loss.

Avoid self-treatment! No medication or home remedy can heal a crack. Using over-the-counter products without a dentist’s supervision may harm your tooth, gums, and overall oral health.

Prevention of Tooth Cracks

To maintain strong and healthy teeth, follow these essential preventive measures:

1. Maintain Excellent Oral Hygiene

Proper brushing and flossing help prevent cavities and decay.

Healthy enamel is naturally resistant to fractures.

Repeated dental treatments (fillings, restorations) can weaken tooth structure over time.

2. Visit Your Dentist Regularly

Schedule dental check-ups at least twice a year, even if you have no symptoms.

Your dentist can strengthen enamel with remineralizing treatments.

Early detection of gum disease, decay, or stress fractures can prevent serious damage.

3. Don't Delay Dental Prosthetics

Missing teeth cause uneven pressure on remaining teeth, leading to cracks, wear, and fractures.

Timely placement of crowns, implants, or bridges helps distribute bite force properly.

Placing a filling in a weak tooth can lead to breakage during chewing, so proper restoration is crucial.

4. Protect Teeth from Sports Injuries

Contact sports like boxing, hockey, and martial arts significantly increase the risk of tooth fractures.

Front teeth (incisors and canines) are especially vulnerable.

Custom-made sports mouthguards absorb impact, reducing the risk of microcracks and fractures.

By following these steps, you can prevent cracked teeth and maintain strong, healthy enamel for years to come.

FAQ

Is It Ever Safe to Leave a Tooth Crack Untreated?

Only if it’s a minor surface crack (microcrack) limited to the enamel. In all other cases, the crack must be treated with a filling, veneer, or crown to prevent further damage.

How Long Can You Wait Before Treating a Cracked Tooth?

If you notice a crack, don’t delay your visit to the dentist. Over time, the crack will worsen, leading to a larger fracture or complete breakage of the tooth.

Does a Cracked Tooth Always Need Extraction?

Not necessarily. The treatment depends on the size and location of the crack:

  • If only the crown is affected, the tooth can usually be restored.
  • If the root is fractured, extraction is necessary since no restoration can stabilize it.

Can You Brush a Cracked Tooth?

Yes! It’s important to remove plaque to prevent gum inflammation. However, be gentle, especially if tooth fragments feel loose or cause pain.

Is Cracked Tooth Treatment Painful?

No! For minor cracks, simple smoothing (enamel reshaping) is painless. For deeper cracks, local anesthesia ensures a completely pain-free procedure. Modern anesthetics make dental treatments comfortable and stress-free.
