What is a cracked tooth?
A cracked tooth is a tooth with a break in the hard surface of enamel or deeper tooth structure. Cracks can follow biting something hard, a fall or blow to the mouth, grinding, or long-term wear. Healthdirect lists eating something hard, falls and facial blows among common causes of dental injury, which can include cracked or broken teeth (healthdirect).
This page is about signs people notice, calm interim tips, and when to book a review at AMK Dental Clinic in Mortlake. It does not diagnose crack type or depth, and it does not say whether a filling, crown or another option will suit your tooth. That decision needs an examination. It is general information only.
What signs do people notice?
People often describe one or more of these:
- a brief sharp twinge when they bite, or when they release the bite
- a sudden temperature zing with hot, cold or sweet food or drink
- a rough edge the tongue keeps finding, or a piece that feels newly sharp
Better Health Channel notes that teeth that have been chipped or cracked may or may not be painful — and that you should still see an oral health professional (Better Health Channel). A quiet tooth can still need review. Symptoms alone do not map to severity: a small surface roughness and a deeper crack can feel similar until a dentist looks carefully.
Healthdirect also notes that not all damage to the teeth or mouth is visible after an injury, which is why a dental visit matters after mouth trauma (healthdirect).
What can you do while you arrange a review?
Interim steps while you book:
- Chew on the other side and avoid hard foods on the sore tooth
- Keep brushing with a soft toothbrush; clean around the area without digging
- Rinse with plain water if a fragment feels loose
- If a piece of tooth has broken off and you still have it, store it in milk or saliva in a clean sealed container and bring it along (Better Health Channel)
- Do not glue a rough edge or fragment with household adhesives or DIY bonding — those products are not a dental repair and can make assessment harder
These steps do not fix a crack. They only reduce further load while you arrange care. If symptoms continue, book a dental review at AMK Dental Clinic in Mortlake rather than waiting it out.
When should you book, and when should you call sooner?
Book a dental review if the twinge, temperature zing or rough edge continues, or if you notice a chip after biting something hard. Better Health Channel advises seeing an oral health professional as soon as possible for chipped or cracked teeth, because early repair can improve the outlook for a damaged tooth (Better Health Channel). Healthdirect advises seeing a dentist if a tooth is cracked, chipped, loose or lost after an accident, and notes that treatment can help avoid longer-term damage (healthdirect).
Call sooner — do not wait for a routine slot — if you have facial swelling, injury after a fall or blow, heavy bleeding, or increasing pain with swelling. For trouble breathing or swallowing, heavy bleeding that will not stop, or severe facial swelling, seek emergency medical care (call 000). For urgent mouth-trauma first-aid pathways such as a knocked-out adult tooth, follow what to do in a dental emergency. That emergency post is a complement for swelling and trauma only; this page stays on everyday cracked-tooth signs and booking a review.
Your dentist decides repair options after examining the tooth. This page does not promise a crown, a filling or any other specific treatment.
Booking a review in Mortlake

Common questions
What does a cracked tooth often feel like?
Many people notice a brief sharp twinge when they bite or release a bite, a sudden zing with hot or cold food or drink, or a rough edge the tongue keeps finding. Better Health Channel notes that chipped or cracked teeth may or may not be painful. Symptoms alone do not show how deep a crack is. Book a review at AMK Dental Clinic in Mortlake so your dentist can examine the tooth.
Should I glue a rough edge or broken piece myself?
No. Do not use household adhesives, temporary kits meant for other uses, or DIY bonding on a tooth. Store any broken fragment in milk or saliva in a clean sealed container if you have one, and bring it to your appointment. Better Health Channel advises seeing an oral health professional as soon as possible for chipped or cracked teeth. Book AMK Dental Clinic in Mortlake rather than waiting for a home fix.
What can I do while I wait for an appointment?
Chew on the other side, avoid hard foods on the sore tooth, and keep brushing with a soft toothbrush. Rinse with plain water if a fragment feels loose. Do not dig at a rough edge with sharp household objects. These steps are interim only. They do not repair a crack. Arrange a dental review at AMK Dental Clinic in Mortlake if symptoms continue.
When should I call sooner than a routine booking?
Call sooner if you have facial swelling, injury after a fall or blow, heavy bleeding, or trouble breathing or swallowing. For breathing difficulty, heavy bleeding that will not stop, or severe facial swelling, seek emergency medical care (call 000). For urgent mouth trauma pathways, see what to do in a dental emergency. Otherwise phone AMK Dental Clinic on (02) 9739 6525 or use Contact.
Will I need a crown or a filling for a cracked tooth?
This page does not say which repair fits your tooth. Healthdirect notes that after a dental injury your dentist discusses options once they have examined the mouth. Treatment depends on where the crack sits, how deep it is, and the state of the tooth. Your dentist at AMK Dental Clinic in Mortlake will explain benefits, risks and alternatives after assessment — not from symptoms alone.
