A cracked tooth can happen unexpectedly while eating something hard, from an injury, or due to long-term habits like teeth grinding. Sometimes, it hurts instantly; other times, the pain appears only while chewing or drinking something hot or cold.
Many people hope the crack will “heal on its own,” but teeth don’t function like bones. Understanding what happens when a tooth cracks and how it recovers can help you take the right steps quickly.
What Is a Cracked Tooth?
A cracked tooth occurs when there’s a break or fracture in the enamel (the hard outer layer) or even deeper layers of the tooth. The damage may range from a small surface line to a split that reaches the root.
Cracks can result from:
- Biting or chewing hard foods like nuts, ice, or candies
- Jaw clenching or nighttime teeth grinding (bruxism)
- Sudden impact or injury to the mouth
- Weakened teeth from large fillings or previous dental work
- Sudden temperature changes (such as eating hot food and immediately sipping something cold)
Can a Cracked Tooth Heal Naturally?
Unlike skin or bone, tooth enamel doesn’t have living cells, so it cannot regenerate. However, once treated properly, the discomfort can subside, and the tooth can function normally again. The healing process depends on the depth of the crack, the type of treatment, and how early it’s addressed.
Here’s a general guide to healing time based on the severity of the crack:
1. Surface Cracks (Craze Lines)
Tiny cracks on the enamel that are painless and mostly cosmetic.
Healing time: Usually requires no treatment. The tooth remains healthy.
2. Minor Cracks or Chips
Slight cracks that don’t reach the nerve can be treated with dental bonding or fillings.
Healing time: Approximately 1 to 2 weeks after treatment, once sensitivity has reduced.
3. Moderate Cracks (Reaching the Dentin)
If the fracture extends deeper but not into the pulp, a crown is often used to protect the tooth.
Healing time: Usually 2 to 3 weeks for full comfort after crown placement.
4. Severe Cracks (Affecting the Pulp)
When the inner nerve tissue is exposed, a root canal treatment is required.
Healing time: 3 to 4 weeks for complete relief and stabilization after the procedure.
5. Vertical or Split Tooth
If the crack extends below the gum line or splits the tooth into two parts, extraction may be necessary.
Healing time: The gum tissue heals in 4 to 6 weeks. A replacement option like a dental implant may take longer.
Factors That Influence Healing
Several factors can affect how long recovery takes after a cracked tooth treatment:
- Severity of the fracture — deeper cracks need a longer recovery time.
- Oral hygiene habits — brushing and flossing gently prevent infection.
- Eating habits — avoiding hard or sticky foods speeds up healing.
- Stress and grinding — using a mouthguard can prevent further damage.
- Timely dental care — early diagnosis always leads to quicker recovery.
Tips to Protect and Support Healing
- Avoid biting or chewing hard foods on the affected side.
- Rinse with warm salt water to reduce inflammation.
- Maintain gentle brushing and regular flossing.
- Use a night guard if you grind your teeth.
- Attend follow-up appointments for proper monitoring.
Proper care and professional attention can help preserve a cracked tooth for many years. Ignoring it can lead to infection, increased pain, or tooth loss.
