A cracked tooth can be uncomfortable, stressful, and sometimes difficult to detect. While some cracks cause immediate pain, others may go unnoticed for months. Understanding the signs, causes, and treatment options can help protect your oral health and prevent long-term damage.
Cracked teeth are more common than many people realize and are one of the leading causes of tooth loss in adults. Fortunately, early diagnosis and professional treatment can often save the tooth.
What Causes Cracked Teeth?
Several everyday habits and dental conditions can lead to cracked teeth, including:
- Biting down on hard foods such as ice, nuts, or hard candy
- Teeth grinding or clenching (bruxism)
- Large or old dental fillings that weaken tooth structure
- Trauma from accidents, falls, or sports injuries
- Sudden temperature changes (hot food followed by cold drinks)
- Natural aging and enamel wear
Over time, these factors weaken the enamel, making teeth more prone to cracking.
Types of Tooth Cracks
1. Craze Lines
Small, superficial cracks in the enamel.
They are usually painless and do not require treatment.
2. Fractured Cusp
Often occurs around a dental filling.
Usually painless and does not affect the tooth’s nerve.
3. Cracks Extending Below the Gum Line
These cracks are more serious and require immediate dental evaluation.
If the crack reaches below the gum line, the tooth may not be salvageable.
4. Split Tooth
A tooth that has separated into two or more segments.
In most cases, it cannot be fully saved.
5. Vertical Root Fracture
Begins below the gum and moves upward.
Often causes minimal symptoms until infection develops.
Common Symptoms of a Cracked Tooth
Not all cracks are visible, but you may experience:
- Pain when biting or chewing
- Sensitivity to hot, cold, or sweet foods
- Swollen or tender gums near the affected tooth
- Pain that comes and goes without warning
Because symptoms vary, a dental exam is often the only way to confirm a crack.
How do you know if you have a cracked tooth?

Depending on the severity of the crack, you may not know if one exists even if it is very small. Often times, your dentist will be the one to help diagnose a cracked tooth in conjunction with any symptoms you may be experiencing.
How Dentists Diagnose a Cracked Tooth
Your dentist may use several methods, including:
- Visual examination
- Dental instruments to feel for cracks
- Dental dye to highlight fractures
- Bite tests to locate discomfort
- X-rays to check underlying damage
- Gum evaluation for inflammation
Is a Cracked Tooth an Emergency?
A cracked tooth is not always an emergency, but delaying care increases the risk of:
- Infection
- Nerve damage
- Tooth loss
If pain, swelling, or sensitivity worsens, you should schedule an appointment as soon as possible.

What to Do If You Think Your Tooth Is Cracked
Immediate Steps
- Rinse your mouth with warm water
- Apply a cold compress to reduce swelling
- Avoid chewing on the affected side
- Take over-the-counter pain relievers if needed
- Eat soft foods
These steps are temporary and not a replacement for professional care.
Treatment Options for a Cracked Tooth
Dental Bonding
A tooth-colored resin repairs minor cracks and restores shape.
Dental Crown
A custom-made crown protects and strengthens a damaged tooth.
Root Canal Treatment
If the crack reaches the pulp, removing the infected tissue can save the tooth.
Tooth Extraction
Used when the damage is too severe to repair.
Can a Cracked Tooth Heal on Its Own?
Unfortunately, no.
Once a tooth is cracked, it cannot heal naturally. Treatment is required to prevent further damage or infection.
Can a Cracked Tooth Cause Other Health Issues?
Yes. Infections from cracked teeth can spread and may cause:
- Facial swelling
- Jaw pain
- Sinus issues
- Dizziness in severe cases
Prompt treatment helps prevent complications.
How to Prevent Cracked Teeth
- Avoid chewing hard objects
- Wear a night guard if you grind your teeth
- Maintain good oral hygiene
- Visit your dentist regularly
- Address cavities early
When to See a Dentist
Contact your dentist if you experience:
- Persistent tooth pain
- Sensitivity to temperature
- Swelling or redness
- Pain when chewing
Early treatment helps preserve your natural teeth and prevent costly procedures.
