What are the symptoms of a cracked tooth?
Direct answer
Symptoms of a cracked tooth can include sharp pain when biting, pain when releasing the bite, sensitivity to cold or heat, pain that comes and goes, discomfort around an old filling and difficulty chewing on one side. Some cracks are visible, but many are hard to see without dental examination. A cracked tooth should be assessed because the crack can deepen and may eventually affect the nerve or the root.
Why cracked teeth can be difficult to identify
A cracked tooth does not always hurt constantly. The pain may appear only when chewing, when the tooth flexes or when temperature reaches the inside of the tooth through the crack.
Cracks can occur in teeth with large fillings, after trauma, from grinding or because of long-term bite stress. Early assessment can help decide whether the tooth can be protected with a filling, bonding, crown or other treatment.
Common signs of a cracked tooth
- Sharp pain when biting on the tooth.
- Pain when releasing the bite.
- Sensitivity to cold, heat or sweetness.
- Pain that comes and goes rather than constant pain.
- A feeling that something is wrong around an old filling.
- Difficulty chewing on one side.
- A visible line, fracture or broken piece of tooth.
Cracked tooth symptom guide
| Symptom | What it may suggest | Why assessment matters |
|---|---|---|
| Sharp pain on biting | The crack may open under pressure. | The tooth may need protection before the crack worsens. |
| Pain when releasing the bite | A classic crack-related pattern can be present. | Bite tests and magnification may be needed. |
| Cold sensitivity | The crack may expose dentine or irritate the nerve. | Treatment depends on how deep the crack is. |
| Intermittent pain | The crack may only move during certain chewing forces. | Symptoms can be difficult to reproduce without testing. |
| Swelling or constant throbbing | The nerve or root area may be infected. | Urgent assessment may be needed. |
What happens at Gloss & Floss Dental Care®?
At Gloss & Floss Dental Care® in Stockholm, we examine the tooth, check old fillings, test the bite and assess whether X-rays are needed. Some cracks are not visible on X-rays, so clinical tests and symptom history are important.
Treatment depends on the crack’s depth and direction. Options may include smoothing, bonding, a filling, a crown, root canal treatment or extraction if the tooth has a vertical root fracture or cannot be saved predictably.
When should you seek care?
Book dental care if you suspect a cracked tooth, especially if you have pain when biting, sensitivity, swelling, a broken filling or a tooth that suddenly feels different when chewing.
Practical advice: Avoid chewing hard foods on the affected side until the tooth has been assessed.
Frequently asked questions
Can a cracked tooth heal by itself?
No. Tooth structure does not heal like bone. Symptoms may come and go, but the crack itself does not repair naturally.
Will a cracked tooth show on an X-ray?
Sometimes, but not always. Many cracks are difficult to see on X-rays and require clinical testing.
Does every cracked tooth need a crown?
No. Treatment depends on the depth, size and position of the crack. Some teeth can be repaired with a filling or bonding, while others need a crown or more advanced treatment.
When is a cracked tooth urgent?
It is more urgent if there is swelling, severe pain, pain when biting, fever, bad taste or signs that the tooth is splitting.
