I’ve Cracked a Tooth – What Should I Do?

I’ve Cracked a Tooth – What Should I Do?

22/12/2025

Cracked teeth are more common than you might think. Whether it’s from biting down on something hard, an accident, or even years of clenching and grinding, a crack in your tooth should never be ignored.

While a small crack might not seem serious at first, leaving it untreated can lead to bigger problems for your tooth and overall oral health.

Why Cracks in Teeth Are a Concern

Teeth are designed to withstand strong biting forces, but once a crack develops, the structure is weakened. If left untreated:

• The crack can spread further – making the tooth more likely to split or fracture completely.
• The pulp (nerve) may become involved – once bacteria reach the pulp, the tooth can become painful or infected, often requiring root canal treatment.
• Tooth loss is a risk – in severe cases, a crack that extends deep below the gum line may leave the tooth beyond repair.

Signs You May Have a Cracked Tooth

A cracked tooth may not always be symptomatic but this does not always mean that the tooth is safe and not at risk of getting worse.  Some patients may notice:

• Sharp pain when biting or chewing
• Sensitivity to hot or cold
• Intermittent discomfort that comes and goes
• A visible line or fracture on the tooth surface

Even if the pain isn’t constant or the tooth isn’t hurting, if you notice a crack, it’s important not to delay seeing your dentist.

How Can a Cracked Tooth Be Treated?

The best way to protect a cracked tooth is to restore its strength and stability before the crack worsens.

• Onlay – A partial cover that reinforces the weakened area of the tooth.
• Crown – A full protective cover that surrounds the entire tooth, restoring its form, structure, and function.

Both options are custom-made to fit securely and are designed to prevent the crack from spreading, while allowing you to bite and chew normally again allowing you to keep the tooth for longer.

Conclusion

A cracked tooth will not heal on its own. The longer it’s left untreated, the greater the risk of pain, infection, or losing the tooth altogether.

By placing a crown or onlay, your dentist can protect the tooth, stop the crack from worsening, and keep your smile strong and functional for years to come.
