A sharp zing when you release a bite can point to a cracked molar, and cracks can reach the pulp. For households in Caledon, we assess the crack, the nerve and whether the tooth can be rebuilt.
Biting on a seed or an unexpected bit of bone, then feeling a sharp zing as you open, is a classic story with cracked molars. The crack itself is often invisible to you. Over time it can let bacteria and irritation reach the pulp, the living tissue inside, and that is when a root canal may come into the conversation.
Whether it actually helps depends on where the crack runs. Some cracks stay in the crown of the tooth and can be managed with a protective restoration, with or without canal treatment. Others extend deep down the root, which can make the tooth impossible to restore. The examination has to work out which situation you are in.
For anyone travelling from Bolton or one of Caledon’s other villages, an early assessment gives you options while they still exist. Ask what the dentist can see, whether the pulp is involved, how the tooth would be protected, and whether an endodontist should take a closer look before any decision is made.
Cracked teeth can be elusive. Note when the first jolt happened, what you were eating, how often it recurs and any large fillings or crowns on that side.
Pain that flashes as you let go of a bite is a common feature of cracks, though other problems can cause it. Note which foods trigger it. Please avoid deliberately biting hard to reproduce it, since that can extend a crack; the dentist has gentler ways to test.
At first, a cracked tooth may react briefly to cold. If the reaction begins to last, appears without a trigger or wakes you, the pulp may be more affected. That change is important to report.
A localized swelling, a bump that keeps returning or a narrow pocket along one side of a molar can be linked to a deep crack or an infection. Mention any taste or drainage. Comfort for a stretch does not mean the crack has healed; teeth do not knit back together.
Call promptly about significant pain or swelling. If swelling affects breathing or swallowing, seek emergency medical care immediately.
Provided the crack is limited and the pulp can be treated, keeping the molar with a protective restoration may be realistic. A tooth that still chews comfortably is an asset to your bite. Cracks that run deep into the root, however, can make retention unpredictable, so this is weighed carefully.
Expect a candid account of the likely benefit with no guarantee about longevity. Cracked teeth carry particular uncertainty. Ask what the dentist sees, what would change the outlook, and how the final restoration is meant to hold the tooth together under chewing forces.

Magnification, dyes, bite tests and probing along the gum can help show where a crack goes. Ask how far it appears to extend and what that means for restoring the molar afterward.
Sometimes a temporary band or restoration is placed to stabilize the molar while the pulp is assessed or treated. If a second clinician is part of your care, confirm who handles each stage and how findings will be shared.
Cracked molars can be very sensitive to pressure. Tell us about anxiety, jaw discomfort or a past hard appointment, and agree on a pause signal, so the visit can be planned around you.
The sequence and number of visits depend on the crack and the pulp. It is reasonable to ask, before anything starts, what the diagnosis is, how much work is proposed, what it costs, what else could be done and how the tooth will be held together afterward.
Your symptoms are reviewed and the tooth is examined with bite tests, temperature tests and X-rays, keeping in mind that many cracks do not show on X-rays. Ask whether the molar appears restorable and whether an endodontist should assess it.
A temporary band or covering may be placed to brace the tooth. For canal treatment, local anaesthetic is given and a dental dam isolates the molar. Let the team know at once if you feel discomfort.
Affected pulp is removed, and the canals are cleaned, shaped, disinfected and sealed. Sometimes the crack can be examined more closely from inside the tooth. Ask whether that changed the outlook.
Cracked back teeth generally need a restoration that covers and braces its cusps, placed without long delay. Confirm the timing. Follow-up checks healing and whether the crack is behaving, rather than relying on comfort.
Follow the instructions for your current stage. The guidance before the final restoration is often stricter than after.
After numbness fades, chew on the opposite side and avoid ice, hard candy, nuts and crusty bread until the molar is fully restored. A crack can lengthen under force, even with a temporary in place.
With a cracked tooth, the final restoration is especially important. Book it as advised, and if something interferes, call to reschedule quickly rather than leaving the molar unbraced.
Tell us about worsening pain, swelling, a piece breaking off or a temporary that loosens. Describe when it started and what treatment you have had. Use medication only as directed for you.
Fractured teeth can raise several decisions. Write down what you were eating when it started; it can help the assessment.
Book an exam with our Bronte Street team for an assessment of the crack, the pulp and the restoration plan. Bring a note of when the pain started, what you were eating and any questions about saving the molar.
For severe pain or swelling, please call us. Email and online forms are for non-urgent requests.
