A broken or cracked tooth can happen suddenly and may or may not be painful. Prompt assessment is important, as early treatment can often prevent further damage and reduce the risk of infection or tooth loss.

Common causes include:
Some cracks are obvious, while others are difficult to detect and may only cause intermittent symptoms.
Treatment depends on the extent of the damage and may include:
In some cases, temporary stabilisation is provided first, with definitive treatment planned once symptoms settle.
Cracks can worsen over time if not protected, particularly under heavy bite forces.
Not all cracked teeth are painful initially, which is why assessment is important.
Not always. Small fractures may be repaired. Cracked or heavily restored teeth often need cuspal coverage (onlay or crown) to prevent worsening.
Many can. The key is early diagnosis and stabilisation. Cracks that extend deep below the gum line are more difficult and may not be restorable.
We focus on gentle treatment and clear communication. If the tooth is inflamed, we aim to relieve pain quickly and stabilise the situation.
If pain or sensitivity is present:
The priority is comfort and preventing further damage.
We’ll advise on long-term protection, particularly if the break relates to grinding or tooth wear.
If swelling or severe pain develops, contact the practice urgently.
If you’re unsure whether it’s urgent, you should contact us promptly if you have:
When you attend with a broken or cracked tooth, we will:
The aim is to understand the extent of the damage and which treatment will protect the tooth long-term.
Not all cracked teeth need the same treatment. The decision depends on the depth and location of the crack, and on how the tooth functions in the bite.
| Step | Assessment Question | Yes – Likely Diagnosis | Yes – Recommended Action | No – Next Step / Action |
| 1 | Is the crack only on the surface? | Craze line | No treatment required; monitor over time | Move to Step 2 |
| 2 | Has a piece of the tooth broken away? | Fractured cusp | Tooth usually restorable; crown or protective restoration recommended | Move to Step 3 |
| 3 | Is there pain when biting or releasing? | Cracked tooth syndrome | Protective crown recommended; bite assessment important; early treatment improves prognosis | Monitor closely; further testing may be required |
| 4 | Does the crack extend deep into the tooth or below the gum? | Possible split tooth or vertical root fracture | Tooth often not restorable; extraction is usually required | Conservative protection and monitoring; review response to treatment |
| 5 | Is the tooth heavily worn or under high bite forces? | High risk of crack progression | Bite management and protective treatment are important; a night guard may be recommended | — |
Early cracks are often manageable and protectable. Delayed treatment increases the risk of fracture and tooth loss.
Your dentist will assess the tooth carefully and explain which category it falls into. Where cracked teeth are associated with significant tooth wear, bite changes, or complex restorative planning, Dr Kevin Gilmore will be involved in overseeing the treatment planning to ensure the most appropriate and predictable outcome.
Not all cracks are emergencies — but all cracks deserve assessment. Early diagnosis gives the best chance of saving the tooth. Many broken or cracked teeth can be saved, especially when treated early. Prompt assessment improves comfort, predictability, and long-term outcomes.
