A cracked tooth can be difficult to recognize. You may feel sharp pain when chewing, sensitivity to hot or cold foods, or discomfort that comes and goes even though the tooth looks normal.
Understanding how to fix a cracked tooth starts with determining where the crack is and how far it extends. A shallow enamel crack may only need monitoring, while a deeper fracture may require a filling, crown, root canal treatment, or extraction.
A dental examination helps determine the type of crack and the most appropriate treatment.
What Does a Cracked Tooth Feel Like?
Cracked tooth symptoms often come and go. According to the American Association of Endodontists, symptoms can vary depending on the location and extent of the crack.
Common signs include:
- Sharp pain when biting or releasing your bite
- Sensitivity to hot or cold foods and drinks
- Pain that comes and goes
- Discomfort when chewing on one side
- Tenderness around the affected tooth
- Swelling near the tooth in some cases
A crack may allow parts of the tooth to move slightly under biting pressure. This movement can irritate the pulp, which contains nerves and blood vessels inside the tooth.
Deeper cracks may eventually affect the pulp or tissues around the tooth.
What Causes a Cracked Tooth?
Teeth can crack from a sudden injury or repeated pressure over time.
Common causes include:
- Biting ice, hard candy, or unpopped popcorn kernels
- Grinding or clenching your teeth
- Large fillings that leave less natural tooth structure
- Sports injuries or falls
- A direct blow to the mouth
- Using your teeth to open packages or containers
- Repeated heavy biting forces
Teeth that already have large restorations or weakened areas may also be more vulnerable to fractures.
What Are the Different Types of Cracked Teeth?
Different types of cracks can affect different layers of a tooth. Identifying the type of fracture helps guide treatment.
| Type of Crack | What It Means | Possible Treatment |
| Craze line | A shallow line limited to the enamel | Usually monitoring |
| Fractured cusp | Part of the chewing surface breaks, often near a filling | Filling, onlay, or crown |
| Cracked tooth | A crack extends from the chewing surface toward the root | Crown, with root canal treatment if the pulp is damaged |
| Split tooth | The tooth has separated into distinct sections | Treatment depends on the extent; extraction may be necessary |
| Vertical root fracture | A fracture begins in the root and extends upward | Root removal or tooth extraction may be necessary |
Craze lines are common and usually do not cause pain. Structural cracks involving deeper tooth layers require closer evaluation because they may affect the strength or health of the tooth.
What Should You Do After Cracking a Tooth?
Home care cannot repair the fracture, but a few steps can help protect the tooth until you receive dental care.
You can:
- Rinse your mouth gently with warm water.
- Chew on the opposite side.
- Avoid hard, sticky, or crunchy foods.
- Avoid very hot or very cold foods if they trigger sensitivity.
- Apply a cold compress outside the cheek if swelling develops.
- Place clean, moist gauze over the area if cold air causes discomfort.
Avoid placing aspirin directly against the gums or damaged tooth because it can irritate soft tissues. Also evaluate ongoing or sharp biting pain. The AAE’s tooth pain guide lists a cracked tooth as a possible cause of sharp pain when biting.
How Does a Dentist Diagnose a Cracked Tooth?
Fine cracks can be difficult to see during a basic visual examination. Dentists may combine several findings before making a diagnosis.
An evaluation may include:
- Asking when the pain occurs
- Checking where biting pressure triggers discomfort
- Testing the tooth’s response to temperature
- Examining the tooth under magnification
- Shining light through the tooth to reveal fracture lines
- Measuring gum depths around the tooth
- Taking dental X-rays when appropriate
X-rays may help identify changes around the root, decay, bone loss, or other problems. Very fine cracks may not always appear clearly on a standard dental X-ray.
Treatment decisions depend on more than simply seeing a crack. The dentist also considers the location and depth of the fracture, pulp health, symptoms, bite forces, and how much healthy tooth structure remains.
How to Fix a Cracked Tooth?
Treatment depends on the type of crack, how far it extends, and whether the pulp or surrounding tooth structure has been affected. After examining the tooth, your dentist may recommend one of the following options.
Dental Bonding or Filling
Dental bonding or a tooth-colored filling may be suitable for a small chip or minor surface damage. Composite resin is applied, shaped to match the tooth, and hardened to restore its form. Deeper structural cracks usually require a stronger restoration to support the tooth.
Inlays and Onlays
An inlay or onlay may be used when the damaged area is too large for a filling but does not require a full crown. These custom restorations strengthen the affected area while preserving as much healthy tooth structure as possible.
Dental Crown
A dental crown covers and protects the weakened portion of the tooth while helping distribute biting pressure more evenly. It is often recommended for a fractured cusp or structural crack that needs added support. A crown can protect the tooth, although it cannot make the existing crack heal.
Root Canal Treatment
Root canal treatment may be needed when a crack causes significant inflammation, damage, or infection within the pulp. The affected pulp is removed, the inside of the tooth is cleaned and sealed, and a crown is often placed afterward to protect the remaining tooth structure.
Tooth Extraction and Replacement
Extraction may be necessary when a crack extends deeply below the gum line, reaches far into the root, or splits the tooth into sections that cannot be restored. After removal, replacement options may include a bridge, removable partial denture, or dental implant, depending on your oral health and treatment needs.
Can You Fix a Cracked Tooth Naturally at Home?
Home remedies cannot permanently repair a structural crack. Tooth enamel and dentin do not grow back together the way a broken bone can heal. Warm-water rinses, softer foods, and avoiding pressure on the tooth may reduce irritation temporarily, but they cannot seal the fracture.
Clove oil, salt-water rinses, or other home remedies should not replace a professional evaluation.
A dentist needs to determine how deep the crack extends before recommending treatment.
Can a Cracked Tooth Be Saved?
Many cracked teeth can be preserved, especially when the fracture is identified before it extends too deeply.
The possibility of saving the tooth depends on:
- Where the crack begins
- How far it extends
- Whether the pulp is healthy
- Whether infection is present
- How much healthy tooth structure remains
- Whether the tooth can be predictably restored
A fractured cusp, for example, may often be restored with an onlay or crown. A crack extending deeply below the gum line or through the root may have a less predictable outlook. An examination is necessary to determine whether preserving the tooth is realistic.
How Can You Prevent a Cracked Tooth?
Not every crack can be prevented, but reducing unnecessary stress on your teeth can lower the risk.
Helpful habits include:
- Avoid chewing ice or other very hard objects.
- Stop using your teeth to open packaging.
- Wear a mouthguard during contact sports.
- Ask about a night guard if you grind or clench your teeth.
- Have loose or damaged restorations evaluated.
- Attend regular dental examinations.
- Address persistent bite discomfort rather than ignoring it.
These habits can reduce repeated forces that weaken tooth structure over time.
When Should You See a Dentist for a Cracked Tooth?
Schedule a dental evaluation if you notice sharp biting pain, recurring sensitivity, swelling, or discomfort around a tooth after an injury. Cracks vary widely in depth and severity, so treatment depends on what the examination shows. A small defect may need monitoring or a simple restoration, while more serious damage may require a crown or root canal treatment. Avoid chewing on the affected side until the tooth is evaluated. An earlier assessment can offer more treatment options and help protect the remaining natural tooth.

FAQs
Can a cracked tooth heal on its own?
A structural crack cannot grow back together on its own. Minor craze lines may only need monitoring, while deeper cracks require professional evaluation. Treatment focuses on protecting the tooth, controlling symptoms, and reducing the risk of further damage.
How to fix a cracked tooth if the pain comes and goes?
How to fix a cracked tooth depends on the fracture’s location and depth. Intermittent pain still deserves evaluation because symptoms can vary. Treatment may involve bonding, an onlay, a crown, root canal therapy, or extraction.
Does every cracked tooth need a crown?
A crown is not necessary for every crack. Craze lines may need no restorative treatment, while minor chips can sometimes be repaired with bonding. Structural cracks or weakened cusps are more likely to need greater protection.
