Cracked tooth syndrome — symptoms and fixes

By the Berala Dental clinical team. Educational information only — this article is general information and is not a substitute for personalised dental advice. Please book a consultation to discuss your individual needs.

Cracked tooth syndrome is when a small crack in a tooth causes sharp, often fleeting pain — typically when biting down or releasing — and it can be tricky to diagnose because the crack is often too fine to see. Common signs include pain on biting that disappears quickly and sensitivity that's hard to pinpoint. Here's how to recognise it and why getting it checked early matters.

Common signs of a cracked tooth

• A sharp pain when biting that disappears quickly afterwards
• Pain when you release a bite, not just when you press down
• Sensitivity to hot, cold or sweet that's hard to locate
• Discomfort that comes and goes rather than a constant ache
• Pain only with certain foods or at a particular angle

What causes teeth to crack?

• Grinding or clenching (bruxism)
• Biting something hard, like ice, nuts or a popcorn kernel
• Large or old fillings that weaken the remaining tooth
• Sudden temperature changes in the mouth
• General wear and tear over time

Why cracks are so tricky to diagnose

Some cracks are very fine and don't show up easily, even on an x-ray. Diagnosis usually involves an examination and a few simple tests — such as biting on a special tool — to work out which tooth is involved and how deep the crack goes. Because symptoms come and go, it helps to note when the pain happens so we can pin it down faster.

Why it's worth acting early

Left alone, a crack can sometimes deepen over time, which may turn a small problem into a bigger one. Getting it assessed early gives you more options and a better chance of keeping the tooth comfortable and functional.

What can be done about it

The right approach depends entirely on where the crack is and how far it extends — something we can only determine by examining the tooth. After an assessment, we'll talk you through the options for your specific situation and, if a specialist's input is the best path, help arrange a referral.

What about cost?

We don't quote a fixed price online, because it genuinely depends on the tooth and what it needs. The only accurate price is one based on examining your mouth. Book a consultation for an itemised written quote, and check any rebate with your health fund. More on our fees page.

Frequently asked questions

Can a cracked tooth heal on its own?

No — unlike a bone, a cracked tooth doesn't heal itself. The symptoms may come and go, but the crack remains, which is why it's best to have it assessed.

How do dentists find a crack that doesn't show on an x-ray?

We use an examination plus simple tests, such as biting on a special device, along with your description of when the pain happens, to locate the crack.

Is a cracked tooth an emergency?

Not always, but sudden severe pain, swelling or a broken tooth should be seen promptly — see our emergency page. Milder, intermittent symptoms still warrant a check before they worsen.

Will I lose the tooth?

Often no, especially when caught early. The outlook depends on how deep the crack is, which is exactly what an assessment determines.
